Abstract

Abstract PI-PLC is not only involved in the regulation of plant responses to a variety of biotic and abiotic stresses, but also plays an important role in the regulation of plant growth. banana is one of the four most famous fruits in the world, as well as one of the most important tropical fruits in the world. However, in recent years, blight and cold damage have become two major deadly hazards for banana industry, making it particularly important to improve the resistance of bananas to stress. In this study. PI-PLCs gene family of banana encodes 567–698 amino acidsand. It is mainly located in chloroplasts, mitochondria and cytoplasm. Systematic evolution and homology analysis, PI-PLCs gene family of banana is highly clustered, the structure and function are relatively consistent. There were hormones and stress response elements such as methyl jasmonate, auxin and gibberellin, in the promoter region of MaPLCs family members. The proteins coded by all MaPLCs could interact and participate in a series of life-sustaining activities. The study showed that members of the MaPLCs gene family of bananas could be induced to express by auxin, abscisic acid and salicylic acid. And the leaves appeared curl, wilting symptoms, and water-stained spots.
