A research group from the University of Wisconsin-Madison has reported the discovery of a hormone and receptor that control cell expansion in plants. Led by biochemist Mike Sussman, the group describes a signaling pathway that regulates cell expansion in the root cells of Arabidopsis plants. The study describes a hormone secreted by the plant and a surface receptor known as a protein kinase. The hormone uses the receptor to influence a cell's ability to elongate, to accommodate the growth and development of roots, stems, leaves, and other plant parts.

The CGIAR Consortium's Research Program on Climate Change, Agriculture, and Food Security (CCAFS) has released a downscaled, ready-to-be-used climate data which include around 25 Global Climate Models (GCMs) for four Representative Concentration Pathways (RCP) and four time periods (2030s, 2050s, 2070s and 2080s). The newly-released data corresponds to the Intergovernmental Panel on Climate Change's (IPCC) 5th Assessment Report.

Scientists at Iowa State University have sequenced the genome of Fusarium virguliforme, a fungus that is the culprit for sudden death syndrome (SDS) in soybeans. Using the draft genome sequence, scientists have identified candidate genes responsible for SDS in soybeans. According to Madan Battacharyya, leader of the research team, the draft sequence will lead them towards discovering the mechanisms that the pathogen uses to cause SDS, and will explore on using genetic engineering to develop soybeans with resistance to SDS.

An international team of scientists from the University of Warwick, Chinese Academy of Agricultural Sciences, and Syngenta Seeds has described a mechanism that confers resistance in brassica plants to Turnip mosaic virus. This discovery is hoped to lead to introduction of durable resistance into food crops, including the most important brassica crop worldwide Brassica rapa.

Studies conducted in an organic lettuce field managed by the U.S. Department of Agriculture (USDA) indicate that there's more to sweet alyssum than just good looks. Agricultural Research Service (ARS) horticulturist Eric Brennan has identified ways to improve how the pretty white flowers control aphid pests that prey on lettuce leaves. ARS is USDA's chief intramural scientific research agency.

Scientists from Purdue University have discovered a new microbial-like pathway in plants that produces phenylalanine, an amino acid that is a vital component of proteins in all living organisms. Plants mainly synthesize phenylalanine through a chain of chemical reactions that converts the organic acid arogenate to phenylalanine.

Decline in the apparent quality of rice (Oryza sativa L.) grain due to high temperatures during ripening recently became a major concern in many areas in Japan. The occurrence of white-back kernels (WBK) is one of the main problems of heat-induced quality decline. We identified QTLs associated with the occurrence of WBK using recombinant inbred lines (RILs) and verified their effects using near-isogenic lines (NILs)

Scientists from Rothamsted Research have used metabolic and genetic engineering to demonstrate for the first time that it is possible to achieve an eight-fold increase in DHA content in Phaeodactylum tricornutum. The diatom P. tricornutum naturally accumulates high levels of EPA and is considered a good source for industrial production. The study is published in the journal Metabolic Engineering.

Soybean 305423 was developed through particle bombardment and contains gm-fad2-1 and gm-hra expression cassettes, conferring a high oleic acid profile and tolerance to acetolactate synthase (ALS)-inhibiting herbicides. Bioinformatic analyses and genetic stability studies did not raise safety issues. Levels of the GM-HRA protein in soybean 305423 have been sufficiently analysed. Soybean 305423 differs from the conventional counterpart in the seed fatty acid profile and for the presence of the GM-HRA protein.
