Top candidate genes identified for corn's “spotty” defense mechanism

When corn plants come under attack from a pathogen, they sometimes respond by killing their own cells near the site of the attack, committing “cell suicide” to thwart further damage from the attacker. This cell sacrifice can cause very small, often microscopic, spots or lesions on the plant. But up until now it’s been difficult to understand how the plant regulates this “spotty” defense...

Weeds grow like weeds when they grow with corn

The axiom, “growing like a weed,” takes on new meaning in light of changes in gene expression that occur when weeds interact with the crops they infest, according to plant scientist Sharon Clay. Using sophisticated genetic-mapping techniques, the South Dakota State University professor and her research team are documenting how corn and weeds influence one another. “Weeds grow like weeds...

Corn dwarfed by temperature dip suitable for growing in underground controlled facilities

Lowering temperatures for two hours each day reduces the height of corn without affecting its seed yield, a Purdue study shows. This is a technique that could be used to grow crops in controlled-environment facilities in caves and former mines. Raising the crops in isolated and enclosed environments would help prevent genetically modified pollen and seed from escaping into the ecosystem...
