Muti-omics revealed the mechanisms of MT-conferred tolerance of Elymus nutans Griseb. to low temperature at XiZang.

Background: Low temperature seriously limited the development of grass and crops in plateau. Thus, it is urgent to develop an effective strategy for improving the plant cold tolerance and elucidate the underlying mechanisms.

Results: We found that MT alleviated the effects of cold stress on suppressing ENG growth, then improved cold tolerance of ENG.
