Overexpression of LcFIN1 from Sheepgrass Enhances Cold Tolerance in Transgenic Plants
August 19, 2015| |
Sheepgrass (Leymus chinensis (Trin.) Tzvel) is a forage crop highly tolerant to low-temperatures, thus it can survive through winter. However, the mechanism of its tolerance is still unclear. Qiong Gao of the Chinese Academy of Sciences, led a team of researchers and reported the novel transcript factor LcFIN1 (L. chinensis freezing-induced 1) from sheepgrass.
LcFIN1 showed no homology with other known genes and was rapidly and highly induced by cold stress, suggesting its participation in the early response to cold stress. Consistently, ectopic expression of LcFIN1 significantly increased cold stress tolerance in the transgenic plants, as indicated by the higher survival rate and other stress-related indexes after a freezing treatment.
Transcriptome analysis showed that several stress-related genes were differentially expressed in LcFIN1-overexpressing plants, suggesting that LcFIN1 may enhance plant abiotic stress tolerance by transcriptional regulation. The results show that LcFIN1 positively regulates plant adaptation response to cold stress and is a promising candidate gene to improve crop cold tolerance.
