Flavonoids from sorghum plants kill fall armyworm pest on corn; may protect crop

Flavonoids produced by sorghum leaves have shown promising results in combating fall armyworm larvae. When sprayed on the leaves of corn, sorghum flavonoids stunt the growth of fall armyworm and often kill the pest, Penn State researchers report in a new study.

Mutant corn gene boosts sugar in seeds, leaves, may lead to breeding better crop

An abnormal build up of carbohydrates — sugars and starches — in the kernels and leaves of a mutant line of corn can be traced to one misregulated gene, and that discovery offers clues about how the plant deals with stress.

Flavonoids' presence in sorghum roots may lead to frost-resistant crop

​Flavonoid compounds — produced by the roots of some sorghum plants — positively affect soil microorganisms, according to Penn State researchers, who suggest the discovery is an early step in developing a frost-resistant line of the valuable crop for North American farmers.​

Insect-deterring sorghum compounds may be eco-friendly pesticide

Compounds produced by sorghum plants to defend against insect feeding could be isolated, synthesized and used as a targeted, nontoxic insect deterrent, according to researchers who studied plant-insect interactions that included field, greenhouse and laboratory components.
