Plants have unique lock to control expression of genes, study finds

Purdue University scientists have discovered evidence that the repressive structures that plants use to keep genes turned off is built with a potential self-destruct switch. The findings offer insight into ways to control gene expression to alter plants’ characteristics. Purdue University’s Joe Ogas led a study that showed how plants using repressive states to control… Continue reading Plants have unique lock to control expression of genes, study finds

Warmer climate will dramatically increase the volatility of global corn crops

Corn, or maize, is the most widely grown crop in the world. Used in food, cooking oil, industrialized foods, livestock feed and even automobile fuel, the crop is one that both rich and poor people rely upon. Research led by the University of Washington looks at what climate change will mean for global yields of… Continue reading Warmer climate will dramatically increase the volatility of global corn crops

Robots will support, not replace, growers in the future

Co-robots, robots that work with humans rather than replace them, is the future of high-tech horticultural production, according to experts at Wageningen University and Research in The Netherlands. Twenty British growers who attended a 3-day study tour in The Netherlands heard how a different generation of robots can improve productivity by lending a hand, eyes,… Continue reading Robots will support, not replace, growers in the future

What makes some varieties of rice resistant to drought?

In thirty years, the global population of 7 billion will increase by 30% to a staggering 9.1 billion people. Feeding everyone with the same amount of land that is available today will undoubtedly be a challenge. Along with expanding cities gobbling up agricultural and forest land, changing climatic conditions with frequent spells of droughts also… Continue reading What makes some varieties of rice resistant to drought?

High-protein corn also resistant to parasitic weed

The world produces more corn by weight than any other cereal crop. Corn, also known as maize, is a staple food in many countries. But farmers growing corn face many challenges, such as drought, diseases, and pests. A flowering witchweed (Striga asiatica L. O. Krantz) in a conventionally-ploughed maize field on sandy soils in Madziwa,… Continue reading High-protein corn also resistant to parasitic weed

New GM rice from ETH makes micronutrients transportation more efficiently

In the greenhouse, the genetically modified rice enriched sufficient quantities of iron and zinc in the grains. (Image: Navreet Bhullar / ETH Zurich) A team of researchers led by Navreet Bhullar from the Institute of Molecular Plant Biology at ETH Zurich has genetically modified one of the most commonly grown varieties of rice. The advantage… Continue reading New GM rice from ETH makes micronutrients transportation more efficiently

Predicted environmental changes could significantly reduce global production of vegetables

The study, led by the London School of Hygiene & Tropical Medicine (LSHTM), is the first systematically to examine the extent to which projected changes such as increases in temperature and reduced water availability could affect the production and nutritional quality of common crops such as tomatoes, leafy vegetables and pulses. If no action is… Continue reading Predicted environmental changes could significantly reduce global production of vegetables

Nigerian farmers want substandard seed dealers punished

Nigerian Farmers have asked the Federal Government to put in place measure that would check the proliferation of adulterated seeds across the Country. Speaking on behalf of the group at a media dialogue which held in Abuja, the National Vice President of the All Farmers Association of Nigeria, Daniel Okafor, said, a majority of the… Continue reading Nigerian farmers want substandard seed dealers punished

How a genetically modified soybean helped modernize an economy

Based on the research of Paula Bustos, Bruno Caprettini, Jacopo Ponticelli and Gabriel Garber As Brazil grew richer in the 2000s, its agricultural workers left their farms in droves and headed to work in the rapidly growing industrial sector. But what exactly was happening? Did new economic opportunities lure workers off farms or did changes… Continue reading How a genetically modified soybean helped modernize an economy

Gene discovery may yield lettuce that will sprout in hot weather

A team of researchers, led by a University of California, Davis, plant scientist, has identified a lettuce gene and related enzyme that put the brakes on germination during hot weather — a discovery that could lead to lettuces that can sprout year-round, even at high temperatures. The study also included researchers from Arcadia Biosciences and… Continue reading Gene discovery may yield lettuce that will sprout in hot weather
