Xanthomonas oryzae pv. oryzae (Xoo) causes severe bacterial leaf blight (BLB) disease to many Vietnamese major rice cultivars, including the TBR225. OsSWEET13 belongs to group III of the OsSWEET gene family encoding sugar transport proteins, which is considered one of the “susceptibility” genes (S genes) necessary for BLB disease.

In order to assess genetic diversity of a set of 41 Caricaceae accessions, this study used 34 primer pairs designed from the conserved domains of bacterial leaf blight resistance genes from rice, in a PCR based approach, to identify and analyse resistance gene analogues from various accessions of Carica papaya, Vasconcellea goudotiana, V. microcarpa, V. parviflora, V. pubescens, V. stipulata and, V. quercifolia and Jacaratia spinosa.

Rice leaf blight, which is a devastating disease worldwide, is caused by the bacterium Xanthomonas oryzae pv. oryzae (Xoo). The upregulated by transcription activator-like 1 (UPT) effector box in the promoter region of the rice Xa13 gene plays a key role in Xoo pathogenicity.

In Asia, rice is the most important, widely consumed staple food for a large part of the world's human population. Bacterial leaf blight (BB), caused by the bacterium, Xanthomonas oryzae pv. oryzae (Xoo) is one of the major disease affecting Basmati rice production in India. CSR-30 is a very popular high yielding, salt tolerant Basmati variety widely grown in Haryana, India but highly susceptible to BB.

This study aims to find antagonistic bacteria that are able to provide the highest resistance to the growth of pathogenic Xoo bacteria in rice plants. Antagonistic bacteria were isolated from the leaves and roots of rice plants through surface sterilization and serial dilution. Obtained 53 bacterial isolates consisting of 20 bacterial isolates from leaves and 33 bacterial isolates from roots tested hypersensitive to tobacco plants for filtering potential non-pathogenic bacteria.

The metabolite 2-(1,1-diallyl-but-3-enyl)-5-nonyl-phenol isolated from Streptomyces sp. TC1 exhibited antimicrobial activity against bacterial leaf blight pathogen Xanthomonas oryzae pv. oryzae (Xoo). The in vitro antimicrobial activity was found to be between 1.8-2.5 cm in agar well diffusion assay against the tested Xoo isolates and 200 µg/ml in terms of minimum inhibitory concentration. The isolated compound showed well binding with the virulence proteins of Xoo by producing a better docking score in molecular docking studies.

The present study was conducted at the experimental farm of ICAR Research Complex for Eastern Region, Patna, India in Kharif season 2016 with an objective to identify sheath blight and bacterial leaf blight disease resistance rice genotypes under submergence condition in middle Indo Gangetic Plain. The disease incidence was observed at maturity stages during Kharif season 2016. The incidence of sheath blight and bacterial leaf blight of paddy ranged from 18.6 to 39.0% and 15.3 to 34.0%, respectively.

The bacterial leaf blight of rice caused by Xanthomonas oryazae pv. oryzae is the disease of great economics importance in India especially in Bihar. Management of BLB disease can play a vital role in management of rice disease. In the present investigation evolution of different plant extract (botanical) and new chemical on growth of bacteria by poison food technique and sowing by best botanical and new chemical were conducted and antagonistic activity were tested.

Bacterial leaf blight of rice, caused by Xanthomonas oryzae pv. oryzae is not only a problem in India but also worldwide. Management using chemicals is undoubtedly quick in action, restricting the severity and spread of the disease. Both in vitro and in vivo studies were conducted to investigate the inhibitory potential of different chemicals against the bacterial pathogen.

One hundred rice genotypes were analyzed to evaluate the genetic polymorphism and identification of resistant lines to bacterial leaf blight (BLB) disease caused by Xanthomonas oryzae pv. oryzae using simple sequences repeat (SSR) markers. A total of 38 alleles were detected by seven polymorphic markers showing highly polymorphic across all genotypes with an average of 5.42 alleles per polymorphic marker. The marker RM-21, RM-122 and RM-224 produced maximum 6 alleles.

Rice crop accounts for nearly a third of the total area under food grains in India and is the staple food for a significant portion of the world‟s population. Widely varying factors influence the growth of rice in different rice growing areas and render the crop susceptible to various pathogenic and non-pathogenic diseases, resulting in extensive damage of grain and straw yield. Bacterial leaf blight disease of rice caused by Xanthomonas oryzae pv. oryzae (Xoo) is a serious menace to rice production in India, besides other rice producing countries.

A bacterial blight (BB) resistance gene Xa21 linked to pTA248 molecular marker was transferred into Pusa Basmati-1 (IPB-1) to develop improved Pusa Basmati-1 (IPB-1). The bacterial culture Xanthomonas oryzae pv. oryzae (Xoo) was used to create artificial epiphytotic condition. The leaf samples were taken from PB-1 and IPB-1 treated with bacterial blight culture at different time interval (0 hour, 6 hour, 12 hour, 24 hour, 36 hour, 48 hour, 60 hour and 72 hour) to observe level of expression.

Keteki joha, one of the most popular aromatic rice variety of our region was found to be resistant towards BB earlier, but is also becoming highly infested by the disease now a days. This may be due to the climatic change which may lead to the evolution of new races of the pathotype which might not exist earlier in Assam. Bacterial blight (BB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most devastating diseases affecting entire rice acreages. It causes severe yield losses of up to 80% depending on the stage of the crop, cultivar susceptibility, and environmental conditions.

Rice is one of the important cereal crop and known to be affected by many diseases. Bacterial leaf blight of rice is a destructive disease of rice, known to be caused by Xanthomonas oryzae pv. oryzae and it also be reported to cause by species of Pantoea. BLB diseased samples were collected from southern districts of Tamil Nadu and upon isolation, the pathogen was thought to be Xanthomonas oryzae pv. oryzae. But, the results of biochemical and molecular characterization revealed that the causal agent was not Xanthomonas, but a new species of bacterium Pantoea stewartii subsp.

One hundred indigenous collection of rice germplasm were evaluated for ten quantitative traits to assess the genetic variability, heritability, associations and estimation of yield related traits including area under disease progress curve for bacterial leaf blight. was present for all the traits,. In all germplasm, the analysis of variance revealed a wide range of variability and significant differences for the characters under study, indicating the presence of high genetic variability among the genotypes and considerable scope for selection.
