Two research sites in Central Valley have earned a $12.3-million dollar grant to study how the drought is triggering genetic changes in plants. The goal is to see how plants respond genetically to drought conditions and if more hardy plants can reveal the secrets of how they survive.
The scientists will work at the UC Kearney Agriculture Research and Extension Center in Parlier and the UC West Side Research and Extension Center in Five Points. The focus of the research is on Sorghum which, according to researcher Jeff Dahlberg, is particularly drought resistant.
“It one of the most drought tolerant cereal crops that we grow in the world. And there has been a lot of interest in looking at Sorghum and figuring out what that tolerance is,” Dahlberg said.
The sorghum is apparently able to sense when it is facing drought conditions and flip a genetic switch to use less water. In some cases, the plants close their cells to release less water or create more wax to protect their leaves and stems.
In addition to figuring out how the plant is capable of changing its genetics, Dahlberg says they want to know how the plant is able to divine the conditions.
One early thought is drought triggers microbial changes in the soil that Sorghum can detect.
The researchers will grow two different sets of crops. One under drought conditions and another under normal watering conditions. They will then compare and study the differences in the plants.
Dahlberg says their research might focus on sorghum but their goal is much larger. By learning how sorghum is able to adjust to differing environments, the scientist might be able to apply that information to other crops to improve their drought tolerance.
The Energy Department’s Genomic Science Program is funding this project through its Office of Biological and Environmental Research.
