Rice is a staple food for half of the world’s population, but it accumulates the toxic metalloid arsenic (As), which is present in soils and in plants in two forms, arsenate (AsV) and arsenite (AsIII). Chen et al. review the genetics and biochemistry of As uptake and sequestration into the rice grain,…

Many food-producing regions rely on the withdrawal of water from non-renewable underground sources, a condition called groundwater depletion for irrigation (GWD). Globally, GWD increased by 22% between 2000 and 2010. When food produced with GWD is exported, the exporting country is essentially exporting…

Beneficial microbes help plants take up nutrients, confer protection against pathogens, and can even affect flowering time. Busby et al. argue for a coordinated effort between researchers and farmers to study plant microbiomes with the goal of using them to enhance productivity. The authors define and…

Amazing - over 1.5 million views in less than 24 hours - this is a popular video series!

“The benefits of organic agriculture are widely debated. Although some promote it as a solution to our sustainable food security challenges, others condemn it as a backward and romanticized version of agriculture that would lead to hunger and environmental devastation.” Seufert and Ramankutty address…

Due to its highly repetitive, polyploid genome, wheat genomics has lagged behind that of other cereals, but new tools promise to begin closing that gap.  Uauy reviews these new tools, which include access to full genomes of several wheat varieties, gene expression data from hundreds of publicly available…

Aflatoxins are toxic metabolites produced by some species of Aspergillus fungi that can occur on numerous crop plants. When ingested by animals, aflatoxins cause health problems including liver cancer and stunted growth. Thakare et al. used host-induced gene silencing (HIGS) to block aflatoxin production…

Nature journal published a special “Plant Insights” section featuring several excellent reviews.  Zipfel and Oldroyd review Plant signalling in symbiosis and immunity (10.1038/nature22009), Bevan et al. write about Genomic innovation for crop improvement (10.1038/nature22011), Scheres and van der…
