Bacterial brown stripe of rice in soil-less culture system caused by Acidovorax avenae subsp. avenae in China

Abstract

In 2010, the outbreak of a disease with symptoms similar to bacterial brown stripe was observed in rice seedlings planted in a perlite culture system in China. The causal bacterium was identified as Acidovorax avenae subsp. avenae based on its biochemical and physiological characteristics, cellular fatty acid composition, Biolog data, specific PCR detection and 16S rRNA gene sequence analysis. The bacterial isolates caused similar symptoms after inoculation of rice seedlings. This report is the first of bacterial brown stripe of rice in a soil-less culture system caused by A. avenae subsp. avenae in China.

Enhancement of innate immune system in monocot rice by transferring the dicotyledonous elongation factor Tu receptor EFR

“…The three transgenic lines EFR‐8, EFR‐14, and EFR‐39 with different AtEFR expression levels were also used to test whether EF‐Tu responsiveness in the AtEFR transgenic plants increases resistance to bacterial brown stripe using seed germination and growth retardation assays (Li et al ). The wild‐type and transgenic rice lines exhibited no significant differences in plant height and survival rate after treatment with water (Figures B, C, S3C).…”

Sugarcane transcriptome analysis in response to infection caused by Acidovorax avenae subsp. avenae

“…With disease progression, the streaks reach the apical meristem that moistens and then putrefies. Ultimately, if they eventually reach the stem, it will cause cracks that release an unpleasant odor [9]. The gram-negative bacterium Aaa , formerly known as Pseudomonas avenae [10], is responsible for many diseases in economically important monocot plants.…”

Halotolerant bacteria belonging to operational group Bacillus amyloliquefaciens in biocontrol of the rice brown stripe pathogen Acidovorax oryzae

“…The in vivo inhibitory effect of halotolerant bacterial isolates on this pathogen was determined based on the height of rice seedlings, which has been found to be high closely associated with the virulence of Ao in our previous studies (Li et al . ; Masum et al . ; Zhang et al .…”

“…The first symptoms appear as brown stripes on the lower part of the leaf sheath and frequently extend into the sheaths by spreading along the leaf midrib at the seedling stage of rice (Li et al . ). In most cases, the diseased seedlings become stunted and even died before the two‐leaf stage.…”
