Abstract

Approximately more than 50% of India's population relies on rice (Oryza sativa) for their daily nutrition, making it the country's most important crop. The rice plant is susceptible to a number of important diseases, including blast, brown spot, sheath blight, false smut, sheath rot, stem rot, bacterial leaf blight, leaf streak, bakane disease, and khaira disease. A newly emerging disease of rice that exhibits symptoms similar to BLB has only lately been identified in major parts of Asia, such as China, Malaysia, Korea, and Thailand, as well as in other nations, such as Germany, Turkey, Togo, Brazil, and Venezuela. In the past, P. ananatis was discovered to be the pathogen that was causing rice leaf blight in northern India. In this study, a new species of Pantoea was isolated from diseased seeds and plant parts causing leaf and grain blight of rice from Odisha, India. To identify the bacterial pathogen, typical symptoms were described, and morphological, biochemical, and molecular characterization using the 16s r RNA region were performed to confirm the bacteria as Pantoea dispersa

Keywords

Pantoea dispersa, emerging disease, grain blight, 16s rRNA, India

Conclusion

In conclusion, this is the detailed report of Pantoea dispersa-caused rice leaf and grain blight in India with their biochemical and molecular characteristics. The rising number of reports of disease on novel hosts in various regions of the globe validates the idea that this pathogen is an emerging pathogen. In recent times, there has been a growing focus on comprehending the mechanisms behind the many functions of Pantoea in relation to rice plants. Undoubtedly, this study domain merits more investigation
