An asymptomatic crop holds the clues for healthy roots

Baetsen-Young et al. explore the root transcriptomes of soybean and maize plants infected with a fungus. The Plant Cell By Amy Baetsen-Young and Brad Day, Michigan State University  Background: Diverged plant species respond to microbial interactions through different processes, the outcome…

A Hub of Hubs: The Central Role of ZmABI19 in the Regulatory Network of Maize Grain Filling

Cereal grains accumulate large amounts of proteins and starch and are a major source of dietary calories for humans and animals. In maize (Zea mays), most of the storage compounds are synthesized during the grain-filling period of kernel development. Several key transcription factors (TFs) that regulate…
