Disease Development and Discovery of Anatomically Resistant Features towards Bacterial Leaf Streak in Rice

Bacterial leaf streak (BLS) caused by bacterium Xanthomonas oryzae pv. oryzicola (Xoc) is one of the most prominent rice diseases. BLS causes a significant reduction in paddy yields. However, there are limited studies and lack information regarding mechanisms cells affected on tissues severed from this disease. Therefore, study, sensitive variety IR24 was inoculated against BLS, pathogen colonised mesophyll some bundle sheath cells. The infection spreads rapidly towards base apex leaf, but rather slowly to left right sides veins. Another experiment performed unravel anatomical characteristics varieties (TN1, IR24, IR5) resistant (IR26, Dular, IR36) BLS. Susceptible have less thick midrib lamina, high number at primary vascular tissue (midrib), layer sclerenchyma secondary vein, more than two metaxylems vein. Resistant varieties, other hand, consist relatively thickened fewer layers This study contributes new knowledge identifying level fields, helps breeders producing paddies
