英文摘要	Lectin receptor-like kinases (LecRLK) are widespread in higher plants and their effects on abiotic stress tolerance are gradually being reported. However, little information is available on LecRLK functions in bryophytes. Here, an L-type LecRLK gene (PnLecRLK1) was characterized from the Antarctic moss Pohlia nutans. Subcellular localization analysis revealed that PnLecRLK1 was a plasma membrane protein. The expression of PnLecRLK1 was rapidly induced by simulated cold, salt, and drought stresses as well as by exogenously applied abscisic acid (ABA) and methyl jasmonate. Transgenic Arabidopsis plants of overexpressing PnLecRLK1 exhibited enhanced tolerance to chilling-stress and increased ABA sensitivity. Additionally, the expression levels of genes in the C-repeat binding factor (CBF) signaling pathway such as AtCBF1, AtCBF2, AtCBF3 and AtCOR47 were markedly increased in transgenic Arabidopsis. Furthermore, the expression levels of ABA-responsive genes, such as AtABI4, AtABI5, AtMYB2 and AtDREB2A, were also significantly up-regulated in transgenic Arabidopsis. Therefore, our results suggested that PnLecRLK1 functions as a membrane-bound regulator that increases chilling stress tolerance and ABA sensitivity to enable P. nutans to adapt to polar climates.
