“…UV-radiations, temperature and humidity regulates phyllospheric bacterial communities. 3 There are various factors that define phyllospheric microbiota such as temperature, water, topology of the leaf surface, nutrient availability, age of leaves, plant species and leaf physiology. On the surface of the leaves, various morphological parts like trichomes, veins, cell wall junction of epidermis and stomata are the sites rich in microbial community since these regions protect bacteria from UV-radiations as well as other environmental extremes.…”
