The rice XA21 pattern recognition receptor binds a type I secreted sulfated peptide, called axY(S)22, derived from the Ax21 (activator of XA21-mediated immunity) protein. The conservation of Ax21 in all sequenced Xanthomonas spp. and closely related genera suggests that Ax21 serves a key biological function. Here we show that the predicted N-terminal sequence of Ax21 is cleaved prior to secreti...
The nucleotide sequence was determined for the genome of Xanthomonas oryzae pathovar oryzae (Xoo) KACC10331, a bacterium that causes bacterial blight in rice (Oryza sativa L.). The genome is comprised of a single, 4 941 439 bp, circular chromosome that is G + C rich (63.7%). The genome includes 4637 open reading frames (ORFs) of which 3340 (72.0%) could be assigned putative function. Orthologs ...
Sulfones are one of the most important classes of agricultural fungicides. To discover new lead compounds with high antibacterial activity, a series of new sulfone derivatives were designed and synthesized by introducing the aroxymethyl moiety into the scaffold of 1,3,4-oxadiazole/thiadiazole sulfones. Antibacterial activities against three phytopathogens (Xanthomonas oryzae pv. oryzae, Ralston...
Approximately 20,000 of the rice-FOX Arabidopsis transgenic lines, which overexpress 13,000 rice full-length cDNAs at random in Arabidopsis, were screened for bacterial disease resistance by dip inoculation with Pseudomonas syringae pv. tomato DC3000 (Pst DC3000). The identities of the overexpressed genes were determined in 72 lines that showed consistent resistance after three independent scre...
Bacterial leaf blight of rice caused by pathogen Xanthomonas oryzae pv oryzae is a serious pest leading to major loss of rice production world wide. Early detection of pathogen can help in taking necessary precautionary measures to avoid onset and spread of disease. Conventional methods of pathogen identification are laborious, time taking and give inconsistent results. Rapid molecular methods ...
Plants and animals carry specific receptors that recognize invading pathogens and respond by activating an immune response. The rice XA21 receptor confers broad-spectrum immunity to the Gram-negative bacterial pathogen, Xanthomonas oryzae pv. oryzae upon recognition of a small protein, Ax21, that is conserved in all Xanthomonas species and related genera. Here we demonstrate that XA21 is cleave...
Bacterial Leaf Blight (BLB) is the most devastating disease of rice. This disease can reduce grain production by 20-50% . Xanthomonas oryzae pv. oryzae, the causal agent of bacterial leaf blight (BLB) of rice was characterized through pathogenecity and biochemical assays.The development of resistant cultivars has been the most effective and economical strategy to control bacterial leaf blight (...
تنوع ژنتیکی 60 جدایه از xanthomonas oryzae pv. oryzae ، عامل بیماری بلایت باکتریایی برنج، جمع آوری شده از مزارع برنج استان گیلان، با استفاده از نشانگر rapd مورد ارزیابی قرار گرفت. سه جمعیت مد نظر قرار داده شدند: جدایه های جمع آوری شده از خزانه، جدایه های جمع آوری شده از مزرعه و جدایه های جمع آوری شده از خوشه. هشت آغازگر به کار گرفته شده در مجموع، 187 نوار چند شکل ایجاد کردند. بزرگترین قطعه توسط...
ABSTRACT The ability of some phytopathogenic bacterial strains to inhibit the growth of others in mixed infections has been well documented. Here we report that such antagonistic interactions occur between several wild-type strains of the rice bacterial blight pathogen Xanthomonas oryzae pv. oryzae. In mixed inoculations, a wild-type Philippine strain was found to inhibit the growth of a wild-t...
