Comparative physiological and transcriptomic analyses reveal different stress adaptation strategies controlling buckwheat chilling tolerance.

ABSTRACT:

Background

Tartary buckwheat is the most important traditional minor crop in the high and cold mountain area of southwest China. Its growth and development were seriously inhibited by chilling stress. However, the molecular and physiological adaptive mechanisms of chilling stress tolerance in Tartary buckwheat are still not well understood.

Results

This study performed physiological and transcriptome analyses on the seedlings of two low-temperature resistance (LT-R) and three LT sensitive (LT-S) Tartary buckwheat cultivars under normal (22℃) and low (4℃) temperature conditions. The results revealed that LT-R cultivars exhibited smaller changes in oxidative damage and photosynthetic pigment levels (chlorophyll a and chlorophyll b contents) compared to LT-S cultivars. They als
