UK scientists have created a synthetic molecule that, when applied to crops, has been shown to increase the size and starch content of wheat grains in the lab by up to 20%.

The new plant application, developed by Rothamsted Research and Oxford University, could help solve the issue of increasing food insecurity across the globe. Some 795 million people are undernourished, and this year’s El Nino has shown how vulnerable many countries are to climate-induced drought.

The results of the study, published in Nature, detail the method based on using synthetic ‘precursors’ of the sugar trehalose 6-phosphate (T6P) – a first-of-its-kind strategy that used chemistry to modify how sugars are used by plants. Rothamsted Research, which receives strategic funding from the Biotechnology and Biological Sciences Research Council, identified this naturally occurring sugar as being crucial in controlling how wheat uses sucrose, the main fuel generated by photosynthesis. Sucrose is key to the development of wheat grains. They identified that the more T6P that is available to wheat grains as they grow, the greater the yield.

Utilising the chemical expertise of Oxford University’s Chemistry Research Laboratory, a modified version of T6P that could be taken up by the plant and then released within the plant in sunlight was developed. This T6P ‘precursor’ was added to a solution and then sprayed on to the plants, causing a ‘pulse’ of T6P, which resulted in more sucrose being drawn into the grain to make starch. When tested in the lab, under controlled environmental conditions, this approach resulted in an increase in wheat grain size and yield of up to 20%.

The study also demonstrated that application of the precursor molecule could enhance plants’ ability to recover from drought, which could ultimately help farmers to overcome difficult seasons more easily in the future.

Professor Ben Davis, of the Department of Chemistry at Oxford University, said: ‘The tests we conducted in the lab show real promise for a technique that, in the future, could radically alter how we farm not just wheat but many different crops. The “green revolution” in the 20th century was a period where more resilient, high-yield wheat varieties were created, an innovation that has been claimed to have helped save one billion lives. By developing new chemical methods based on an understanding of biology, we can secure our food sources and add to this legacy. That way we can make sure as many people have access to enough food as possible and that the less fortunate can be rescued from unexpected hardship.’

The method has the potential to increase yields across a wide number of crops, as T6P is present and performs the same function in all plants and crops.

Dr Matthew Paul, Senior Scientist (Plant Biology and Crop Science) at Rothamsted Research, said: ‘This study is a proof of concept, showing us that it is possible to influence how plants use the fuel they produce for agricultural benefit, both in terms of yield and also resilience to drier conditions. The next stage of work is to replicate this experiment as much as possible in the field in different environments, for which we’ll need to understand how to scale up production of the T6P precursor and determine the effect that more variable conditions may have on results.’

Wheat plants were grown until each plant flowered, after which varying concentrations of T6P solution (between 0.1 and 10 mM) were added to different plants to assess the effect each concentration had on growth. The wheat was then sprayed with the solutions either on the ears or the whole plant at intervals of five days after the plants first flowered, with just one application sufficient to increase yield. The plants were then harvested once ripe, with the grains weighed and analysed for amount of starch and protein present. To test the responses to drought conditions, the plants were grown until just before the wheat plant developed its stem. It was then deprived of water for ten days, with T6P solutions being added on the ninth of these days. Plants were harvested after re-watering to assess biomass recovery after the drought period.

Certain forward-thinking people square measure reinventing farming as we all know it. Indoor, organic urban farms growing food vertically victimization husbandry and aquaponic principles, square measure maturation round the country. The push for different ways of raising food follow partially, on the heels of native governments outlawing owners from growing vegetable gardens in their yards, and forcing folks to tear out existing, healthy gardens. supplying the wheels of amendment square measure the county, state and central wittingly making an attempt to destroy the organic phenomenon with chemtrails, pesticides, growth hormones and GMOs, as they alter the terribly molecular nature of our food. These actions move the guts, stimulate rage, emotion and worry, and force humans to vary to survive or die.

grow your hanging gardens of BabylonLooking for alternative routes to feed themselves and also the community, massive and little different husbandry ventures square measure shooting up all over. Smaller ventures like the Urban Hydro Project in state capital, Tennessee is that the farm-child of Jeffery Orkin; and his efforts square measure paying off. A demand community support in late 2012 raised over $3,300 in donations, enough cash for Orkin to shop for materials to increase his fledgling indoor organic garden on the highest floor of a domicile building in state capital. though the Urban Hydro Project has solely a hundred thirty five sq. feet of floor house, the space has twelve foot ceilings, and Orkin plans to plant to the ceiling. lovely organic vegetables square measure mature victimization farming, wherever no soil is employed. Orkin says this is often a additional economical methodology of production, and one that produces higher yields and higher tasting organic food year spherical.

While the Urban Hydro Project continues to expand and thrive in state capital, FarmedHere up up outside of Chicago and claims the respect of being the most important indoor vertical farm within the U.S.. based by Jolanta Hardej, it’s placed in a very Brobdingnagian ninety,000 square measure abandoned warehouse in Bedford Park, Illinois. Hardej had the vision as so much back as 2008 to grow contemporary, organic manufacture victimization aquaponic techniques, and no soil. Like Orkin, Hardej says the vegetables square measure higher tasting than once historically mature. Plants at FarmedHere square measure mature in multiple stacked levels and fed by mineral-rich water circulated throughout the system from fish tanks containing hormone-free genus Tilapia fish.

FarmedeHere is trying to provide over a million pounds of contemporary, organic foliate greens, freed from chemicals, pesticides, herbicides, and GMOs.

Indoor farming provides property choices
As additional tight government rules square measure place in situ dominant individual freedoms, and larger efforts square measure created to change the essence of food by companies like Monsanto, the provision of organic, life-staining foods can diminish. because the air and land square measure poisoned chemically and different corrupting parts in a trial to marginalise life, different means that of growing food are going to be required for people who square measure willing to fight to survive the system.

· Indoor husbandry comes like these et al round the country manufacture organic food year spherical, beneath excellent temperature, wetness and lighting conditions

· because of the controlled growing atmosphere, indoor farms offer property agriculture for all — the house gardener, native tailgate markets, and huge food chains such Whole Foods, inexperienced Grocery, and different massive grocery chains tightened organic foods

· Growing manufacture with farming is feasible for individual owners by fixing a special growing station in their homes, garages or sheds. Some vertical growing instrumentality is moveable and may be captive outside in hotter weather if desired.

· Indoor vertical farming incorporates a little footprint, permitting people to grow food victimization aquaponics or farming off from curious government eyes. in addition, little or massive indoor community gardens square measure attainable in smaller-sized buildings, allowing teams to make gardens, purchase provides and share contemporary vegetables along.
