Phylogenetic Characterization and Genome Sequence Analysis of Strains Isolated in Thailand as the Causal Agent of Rice Bacterial Panicle Blight.

is one of the most critical rice-pathogenic bacteria, and it causes bacterial panicle blight (BPB) in rice plants. In 2017, BPB symptoms were observed from rice fields in Chiang Rai, Northern Thailand. Sixty-one isolates obtained from the symptomatic panicles of rice were initially identified as by polymerase chain reaction (PCR) using species-specific primers.

Isolation and Characterization of Bacteriophages Infecting , the Major Causal Agent of Bacterial Panicle Blight in Rice.

Bacterial panicle blight (BPB), caused by , is one of the most severe seed-borne bacterial diseases of rice in the world, which can decrease rice production by ≤75%. Nevertheless, there are few effective measures to manage this disease. In an attempt to develop an alternative management tool for BPB, we isolated and characterized phages from soil and water that are effective to lyse several strains of After tests of host ranges, the phages NBP1-1, NBP4-7, and NBP4-8 were selected for further comprehensive characterization, all of which could lyse BGLa14-8 (phage sensitive) but not 336gr-1 (phage insensitive).

Biological Control Activities of Rice-Associated Bacillus sp. Strains against Sheath Blight and Bacterial Panicle Blight of Rice.

Potential biological control agents for two major rice diseases, sheath blight and bacterial panicle blight, were isolated from rice plants in this study. Rice-associated bacteria (RABs) isolated from rice plants grown in the field were tested for their antagonistic activities against the rice pathogens, Rhizoctonia solani and Burkholderia glumae, which cause sheath blight and bacterial panicle blight, respectively. Twenty-nine RABs were initially screened based on their antagonistic activities against both R.
