Regulatory options for genetically modified crops in India - Choudhary - 2014

Review article

...In summary, this review identifies three fundamental flaws in the current [Indian] biosafety regulatory framework in the form of the EPA Rules 1989 that need to be rectified for the Indian regulatory system to function in a cost-effective and time-bound manner:

Firstly, GM crops are categorized as ‘inherently harmful’ under the ‘hazardous substance’ provision of the Environmental Protection Act 1986, which is scientifically incorrect and gives rise to misperceptions about the safety and potential risk of GM crops to health and environment.

Secondly, the EPA Rules 1989 to regulate GM crops were issued not by a ‘legislative act’ but by an ‘administrative order’ that remains untenable and liable to change with the desire of MOEF, which affects the predictability of the regulations and ignores the need to take into account the views and policies of other concerned ministries and the Parliament of India.

Finally, the Union environment ministry administers the regulation of GM crops in India whereas agriculture falls under the respective State(s). This often confronts approvals posing a ‘Union Vs State’ conflict in decision-making on GM crops.

BBC News - Genetically-modified purple tomatoes heading for shops


By David ShukmanScience editor, BBC News

The prospect of genetically modified purple tomatoes reaching the shelves has come a step closer. Their dark pigment is intended to give tomatoes the same potential health benefits as fruit such as blueberries...

The pigment, known as anthocyanin, is an antioxidant which studies on animals show could help fight cancer. Scientists say the new tomatoes could improve the nutritional value of everything from ketchup to pizza topping...

"With these purple tomatoes you can get the same compounds that are present in blueberries and cranberries that give them their health benefits - but you can apply them to foods that people actually eat in significant amounts and are reasonably affordable," she said.

The tomatoes are part of a new generation of GM plants designed to appeal to consumers - the first types were aimed specifically at farmers as new tools in agriculture.

The purple pigment is the result of the transfer of a gene from a snapdragon plant - the modification triggers a process within the tomato plant allowing the anthocyanin to develop...

Canadian regulations are seen as more supportive of GM and that led to a deal with an Ontario company, New Energy Farms, which is now producing enough purple tomatoes... According to Prof Martin, the Canadian system... look at the trait not the technology... asking if what you're doing is safe and beneficial, not 'Is it GM and therefore we're going to reject it completely'... I hope this will serve as a vanguard product where people can have access to something that is GM but has benefits for them." ...

The aim is to use the juice in research to conduct a wide range of tests including examining whether the anthocyanin has positive effects on humans. Earlier studies show benefits as an anti-inflammatory and in
slowing cancers in mice.

A key question is whether a GM product that may have health benefits will influence public opinion... Prof Martin hopes that the purple tomato juice will have a good chance of being approved for sale to consumers in North America in as little as two years' time. She and other plant researchers in the UK hope that GM will come to be seen in a more positive light...

View from an Iowa farm: In choosing seeds, ‘I’m no pawn of Monsanto’ | Genetic Literacy Project

REPOSTED from Jon Entine's GLP | January 21, 2014 | 
Iowa1
Winter allows a bit of downtime for most farmers. We use it to look back on the prior year and to make plans for the next. We learn from mistakes, failures and successes and attempt to make sense of it all. Personally, I think of each growing season as a clean slate to test out theories and debunk some popular myths about how a corn or soybean plant creates maximum yield. It’s also a time when we get to make the choices about what to plant, where to plant it and what seed to use in each situation. It’s often a very personal and private decision.
I put on some Stevie Ray Vaughn, pull up a mountain of reports, yield data, my own yield maps, spreadsheets, drink lots of coffee, fire up the old adding machine and go at it. You see, our decisions are based on dollars and cents as well as market demand. Each decision must make the most sense to our bottom line and align with the goals we have for land stewardship. It’s a burdensome responsibility. The right decision assures future success for the farming business, puts food on the table for our family and hundreds more, helps ensure the land will yield its bounty for years to come and allows us the income to enjoy life as a family. The wrong decisions can be disastrous.
If you believe many of the cyber-arguments, the seed and chemical company Monsanto has control over what farmers do, say, plant, etc. I’ve been told by denizens of the online forums that Monsanto “controls” farmers. I suppose the company may have secretly adapted some sort of Vulcan mind-meld without our knowledge. Hmmm…… Nope. Maybe Monsanto has some really deep pockets and influential people working for it to tell every commercial farming operation what to do. It’s a daunting task, I’m sure, but completely baseless. No, really, spend some time on the Monsanto Facebook page and read the comments.
This Monsanto-hate is pretty funny, actually. Sometimes I think the critics mistake Monsanto for the Illuminati, a darkly secret society that has influence over every aspect of our lives and has plans for world domination by killing everyone but the chosen few.  That’s a discussion for another time. You see, we farmers are a pretty independent bunch. Just ask our wives. If you tell us to do “A”, we’ll sometimes find a way to do “B” instead, simply because you TOLD us to do “A”. It’s in our blood, our nature. I think my wife truly believes it requires a genetic anomaly to be a farmer.
Besides, Monsanto isn’t the only game in town and has less influence than many think. Some years, they are not even the biggest player. The market share shifts from time to time between several players, depending on product performance, sales programs, and to a small degree company image.. People who think Monsanto is the only game must really tick off DuPont, Syngenta, Dow, Agriliant, and the smaller regional companies. Those poor souls don’t even get an honorable mention in the seed industry from the anti-GMO crowd. I’m pretty sure they think they have some pretty good the products out there, but get no love from the anti’s. Oh well. They’re probably happy that Monsanto has the biggest target.
There are no seed company minions running around out here in the countryside telling us what to do. Sorry to disappoint some, but it simply does not happen. If someone from Monsanto, DuPont, Syngenta, Dow, whomever would come into my office and tell me what to do, he would likely get a tongue lashing that would make a sailor blush, then summarily be told were to put that opinion, and to get the hell out or be removed. By me. Without a shadow of a doubt this would happen, and has.
So, what does influence my decision? Actually, it’s pretty simple and no great secret. You see, I’m a no-nonsense dollars and cents, ‘just the facts’ kind of guy. When the seed salesmen come around each year, we will sit down and have a conversation about what he learned, and what I knew. I’d ask for data, tons of data, then the conversation is over. On goes the Stevie Ray Vaughn, probably something from “Double Trouble” or anything live, and I fire up the coffee pot. I will occasionally call with a specific question on disease resistance or best population for a certain hybrid, but I don’t leave much room for someone “selling” me.
When the decision is made, I call the salesman and tell him the seed order is finalized. He will come in, we might have a brief discussion about supply, or if anything new has arisen that I need to know. Then I usually slide over a slip of paper. On that paper is written a list, my order, of each variety or hybrid I want to plant and how much. At that point, there is no more discussion. End of story. That’s how the decision process goes for me and most farmers that I know. We don’t want to be “sold”; we just want the information to make our own decision. Some farmers can be influenced a bit more than others, but in the end it is a personal decision to buy or not to buy from any particular company.
It’s a dollars and cents on the bottom line kind of thought process that drives the decision. Will non-GMO corn or soy add more to our bottom line in 2014, or not? The economics of it will shift from year to year with available crop premiums, chemical costs and my general willingness to scout, treat, and put in a higher level of management. I’ve never felt pressured to buy a particular type of seed, GMO or not, from Monsanto or any other seed company. I buy what’s best for my farm for this year’s circumstances. Next year it could be different.
For our operation this spring it will be the traited seed, or GMO seed, that I think will have the best impact on the bottom line and the least impact on the environment. The last time we set up a comparison of Bt corn vs non-Bt corn and measured it strictly for yield, the Bt showed a +14bu/ac advantage mainly due to corn borer damage in the non-Bt hybrid. At the current price, that’s about $60/acre. Sure the GMO seed costs more, but adjusting for that, Bt still has a significant advantage in profit per acre. It protects the yield against pests that we might have to use non-selective insecticides to control. It allows us to use more environmentally friendly herbicides and reduce the amount of tillage used to control weeds. Reduced tillage in turn reduces soil erosion and allows us to sequester more carbon in the soil. Reducing tillage saves me wear and tear on the machinery and equipment, saves labor, and saves diesel. It’s a win-win, really, and one that those in the green movement are just starting to realize–or I hope they are.
Next year, the economics of the decision may change and we could plant more non-GMO corn or soybeans. It’s a decision that we re-visit each year. It’s our decision to plant the brand of seed that we feel gives us the best chance of a financially successful season. It’s our decision to plant the brand of seed we want, the crops we choose to, GMO, non-GMO, or if we want to switch our operation to organic.
In the end, it’s a choice that we are free to make and it’s our personal choice. We are not pawns of some Illuminati-like seed and chemical company.
I’m fine with that.
Dave Walton is a full-time farmer in Cedar County Iowa, growing GM and non-GM corn, soybeans, alfalfa and pasture on about 500 acres of the worlds most productive soils.

Arcadia Biosciences and Mahyco Achieve Key Milestone for Salt Tolerant Rice

Technology Will Increase Productivity and Improve Food Security in Southeast Asia --

DAVIS, Calif. and Jalna, INDIA, (January 22, 2014) – Arcadia Biosciences, Inc., an agricultural technology company focused on developing technologies and products that benefit the environment and human health, and Maharashtra Hybrid Seeds Co. Ltd. (Mahyco) today announced the achievement of a key milestone in the development of Salt Tolerant rice.

Arcadia's Salt Tolerance (ST) technology enables plants to produce increased yields under saline water and soil conditions, expanding the range of usable acreage for crop production and reducing requirements for fresh water.

In achieving this key milestone, Mahyco demonstrated that Arcadia’s ST technology significantly increased plant growth and yield in multiple rice lines developed by Mahyco. Rice varieties incorporating ST technology showed substantial increases in key plant performance measures.

Rice is the world’s second-largest crop, grown on 161 million hectares annually. It plays a critical role in food security for more than half of the world’s population. India, with a population of more than 1.2 billion, is the second most populous country in the world. The United Nations Food and Agriculture Organization (FAO) estimates that 221 million people in India, or about one-fifth of the population, are undernourished. As such, there is significant pressure on Indian farmers to increase agricultural productivity.

“With the growing demands on fresh water and land resources for agriculture, the ability to maintain high crop yields in salt-impacted environments is critical,” said Eric Rey, president and CEO of Arcadia Biosciences. “This key technology is just one of a number of improvements Arcadia and Mahyco are developing together to increase farm productivity and reduce the overall environmental impact of agriculture in the region,” he added.

"With this milestone, we are closer to bringing the benefits of this technology to the farmers who are challenged with increased salinity in their farms and improving the overall productivity of the crop," said Usha Zehr, chief technology officer of Mahyco.

A high-energy-density sugar biobattery based on a synthetic enzymatic pathway


Biotech that could change the real technology scene:

High-energy-density, green, safe batteries are highly desirable for meeting the rapidly growing needs of portable electronics. The incomplete oxidation of sugars mediated by one or a few enzymes in enzymatic fuel cells suffers from low energy densities and slow reaction rates. Here we show that nearly 24 electrons per glucose unit of maltodextrin can be produced through a synthetic catabolic pathway that comprises 13 enzymes in an air-breathing enzymatic fuel cell. This enzymatic fuel cell is based on non-immobilized enzymes that exhibit a maximum power output of 0.8 mW cm−2 and a maximum current density of 6 mA cm−2, which are far higher than the values for systems based on immobilized enzymes. Enzymatic fuel cells containing a 15% (wt/v) maltodextrin solution have an energy-storage density of 596 Ah kg−1, which is one order of magnitude higher than that of lithium-ion batteries. Sugar-powered biobatteries could serve as next-generation green power sources, particularly for portable electronics.

Cultivation of Bt Brinjal begins in Bangladesh


Bangladesh formally started the cultivation of the country's first genetically modified (GM) crop--Bt Brinjal today.

As part of the initiatives, Bangladesh Agricultural Research Institute (BARI) distributed saplings of the new crop among 20 farmers of four regions.

But, the authorities decided not to sell out the new variety in the market at present, said Jahurul Islam, chief scientific officer of BARI’s Gazipur region.

The speciality of the Bt Brinjal is that the farmers do not need to spray pesticides on it.

Usually, farmers have to spray pesticides up to 80 times in a cropping season of brinjal against a recommended dose of 25, making the vegetable highly toxic.

The new verities developed by the scientists of BARI are—BARI Bt (Uttara), BARI Bt (Kajla), BARI Bt (Nayontar) and ISD006 Bt BARI.

Agriculture Minister Matia Chowdhury today distributed the saplings among the farmers at a programme in the city’s Bangladesh Agriculture Research Centre.

“We have decided to start cultivating Bt brinjal after different necessary tests at home and abroad. We took long time to experiment all pros and cons for introducing the cultivation of this variety”, she said while addressing as the chief guest....

Natural GMOs Part 189. Pathogenic plant virus jumps to honeybees

21-Jan-2014 American Society for Microbiology

A viral pathogen that typically infects plants has been found in honeybees and could help explain their decline. Researchers working in the U.S. and Beijing, China report their findings in mBio, the online open-access journal of the American Society for Microbiology.

The routine screening of bees for frequent and rare viruses "resulted in the serendipitous detection of Tobacco Ringspot Virus, or TRSV, and prompted an investigation into whether this plant-infecting virus could also cause systemic infection in the bees," says Yan Ping Chen from the U.S. Department of Agriculture's Agricultural Research Service (ARS) laboratory in Beltsville, Maryland, an author on the study.

"The results of our study provide the first evidence that honeybees exposed to virus-contaminated pollen can also be infected and that the infection becomes widespread in their bodies," says lead author Ji Lian Li, at the Chinese Academy of Agricultural Science in Beijing.

"We already know that honeybees, Apis melllifera, can transmit TRSV when they move from flower to flower, likely spreading the virus from one plant to another," Chen adds.

Notably, about 5% of known plant viruses are pollen-transmitted and thus potential sources of host-jumping viruses. RNA viruses tend to be particularly dangerous because they lack the 3'-5' proofreading function which edits out errors in replicated genomes. As a result, viruses such as TRSV generate a flood of variant copies with differing infective properties.

One consequence of such high replication rates are populations of RNA viruses thought to exist as "quasispecies," clouds of genetically related variants that appear to work together to determine the pathology of their hosts. These sources of genetic diversity, coupled with large population sizes, further facilitate the adaption of RNA viruses to new selective conditions such as those imposed by novel hosts. "Thus, RNA viruses are a likely source of emerging and reemerging infectious diseases," explain these researchers.

Toxic viral cocktails appear to have a strong link with honey bee Colony Collapse Disorder (CCD), a mysterious malady that abruptly wiped out entire hives across the United States and was first reported in 2006. Israel Acute Paralysis Virus (IAPV), Acute Bee Paralysis Virus (ABPV), Chronic Paralysis Virus (CPV), Kashmir Bee Virus (KBV), Deformed Wing Bee Virus (DWV), Black Queen Cell Virus (BQCV) and Sacbrood Virus (SBV) are other known causes of honeybee viral disease.

When these researchers investigated bee colonies classified as "strong" or "weak," TRSV and other viruses were more common in the weak colonies than they were in the strong ones. Bee populations with high levels of multiple viral infections began failing in late fall and perished before February, these researchers report. In contrast, those in colonies with fewer viral assaults survived the entire cold winter months.

TRSV was also detected inside the bodies of Varroa mites, a "vampire" parasite that transmits viruses between bees while feeding on their blood. However, unlike honeybees, the mite-associated TRSV was restricted to their gastric cecum indicating that the mites likely facilitate the horizontal spread of TRSV within the hive without becoming diseased themselves. The fact that infected queens lay infected eggs convinced these scientists that TRSV could also be transmitted vertically from the queen mother to her offspring.

"The increasing prevalence of TRSV in conjunction with other bee viruses is associated with a gradual decline of host populations and supports the view that viral infections have a significant negative impact on colony survival," these researchers conclude. Thus, they call for increased surveillance of potential host-jumping events as an integrated part of insect pollinator management programs.
