Texas A&M AgriLife Research scientists have discovered a ribonucleic acid, or RNA, that can increase the thale cress plant’s resistance to stress from drought and salt.
The discovery could help illuminate a new pathway to engineering drought- and salt-tolerant plants, including food crops, said Dr. Liming Xiong, AgriLife Research associate professor,Dallas.
“This is the first finding of a long non-coding RNA, or lncRNA, that regulates plant tolerance to adverse, non-physiological external factors,” Xiong said.
The lncRNA his team discovered in thale cress plants existed in low numbers under non-stress conditions, but levels increased when the plants encountered drought or salt stress, he said. Manually increasing the level of the lncRNA showed corresponding increases in drought and salt tolerance compared with plants where the lncRNA level was unaltered.
Researchers in the Department of Aerospace Engineering have partnered with NASA Langley Research Center to design reflectors that redirect solar power to the moon’s craters.
