Crop physiologist to study phosphorus availability and storage root growth
A researcher in Penn State’s College of Agricultural Sciences has received a $650,000 grant from the U.S. Department of Agriculture to lead a multi-university team in a study focused on the anatomical, physiological and genetic factors underlying phosphorus-stress-induced reprogramming of storage root architecture.

Future corn crops could have higher drought tolerance
A team of scientists led by Pennsylvania State University has recently identified a gene encoding a transcription factor (a protein useful for converting DNA into RNA) which triggers a genetic sequence that enables corn roots to acquire more water and nutrients. This finding could lead to the breeding of corn crops able to withstand droughts and low-nitrogen soil conditions, and thus improve global food security.
