磷脂酰肌醇转移蛋白(PITP)家族能够结合特定的脂质,在植物生命的不同阶段执行各种生物学功能。但PITP在水稻中的功能尚不清楚。本研究从水稻基因组中鉴定了30个PITPs,这些PITPs在理化性质、基因结构、保守结构域和亚细胞定位等方面存在差异。OsPITPs基因的启动子区包含至少一种激素反应元件,如茉莉酸甲酯(MeJA)和水杨酸(SA)。此外,水稻稻瘟菌感染对OsML-1、OsSEC 14 -3、OsSEC 14 -4、OsSEC 14 -15和OsSEC 14 -19基因的表达水平产生显著影响。基于这些发现,OsPITPs可能参与了水稻对M.通过Me JA和SA途径感染。
The family of phosphatidylinositol transfer proteins (PITPs) is able to bind specific lipids to carry out various biological functions throughout different stages of plant life. But the function of PITPs in rice plant is unclear. In this study, 30 PITPs were identified from rice genome, which showed differences in physicochemical properties, gene structure, conservation domains, and subcellular localization. The promoter region of the OsPITPs genes included at least one type of hormone response element, such as methyl jasmonate (Me JA) and salicylic acid (SA). Furthermore, the expression level of OsML-1, OsSEC14-3, OsSEC14-4, OsSEC14-15, and OsSEC14-19 genes were significantly affected by infection of rice blast fungus Magnaporthe oryzae. Based on these findings, it is possible that OsPITPs may be involved in rice innate immunity in response to M. oryzae infection through the Me JA and SA pathway.
