Cowpeas could add sustainability to cropping systems

...r that," Payne said. The crop can be harvested at flowering for forage and at pea production, as with blackeyed peas. By doing both, he can compare water usage and determine potential water stress on the next crop. "Our hope is the wheat yields will increase following cowpeas, as well as the sorghum," Payne ...

NSF awards 19 new projects to better undestand genetic processes in plants of economic importance

Scientists will focus on the genes which encode the chloroplast-targeted proteins that trigger photosynthesis. Understanding how these genes operate could yield significant breakthroughs in biotechno...

This hotspot is home to about 5,300 flowering plant species (of which almost 4,000 are endemics), about a third of the world's oak and pine tree species, and over 1,500 vertebrate species (including 134 endemic species). Among many charismatic flagship species in the region is the volcano rabbit...
