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 ...
As causal agents of bacterial wilt in pastures and meadows, bacteria of the species Xanthomonas translucens are a serious issue in forage grass production. So far, only little is known about host-pathogen interactions at the molecular level and the lack of comprehensive genome data impeded targeted breeding strategies towards resistant forage grass cultivars. Here we announce the draft genome s...
Pathogenic bacteria rely on secreted effector proteins to manipulate host signaling pathways, often in creative ways. CE clan proteases, specific hydrolases for ubiquitin-like modifications (SUMO and NEDD8) in eukaryotes, reportedly serve as bacterial effector proteins with deSUMOylase, deubiquitinase, or, even, acetyltransferase activities. Here, we characterize bacterial CE protease activitie...
The study of small heat shock proteins in plant-pathogen interactions is a subject that has to be further investigated. While Hsp70 and Hsp90 participate in the defense response, the role of this small Hsps remains elusive. In this work we analyzed the expression of small Hsps in citrus canker and the bacterial spot of pepper as well as in the incompatible interactions of the bacterial pathogen...
Distribution of copper resistance gene variants Xanthomonas citri subsp. and euvesicatoria pv. perforans | Yi-Ru Lai, Chih-Hung Lin, Chun-Pi Chang, Hui-Fang Ni, Wen-Shi Tsai, Chien-Jui Huang Agricultural Journals
در این تحقیق اثر غلظتهای مختلف عصارههای آبی، استونی و متانولی گالهای زنبور Aphelonix persica روی درختان بلوط ایرانی که از جنگلهای زاگرس جمعآوری، خشک و آسیاب شده بودند، بر روی رشد باکتریهای Xanthomonas axonopodis pv. phaseoli عامل بیماری سوختگی معمولی لوبیا، Erwinia. amylovora عامل بیماری آتشک سیب و گلابی، Agrobacterium tumefaciens عامل بیماری گال مو و Psuedomonas syringae pv. tabaci عامل ...
endophytes are important resources of bioactive compounds and due to their potential in theproduction of secondary metabolites, they are regarded as a potential reservoir ofbiotechnological applications. in this study, the bioactivity of bacteria and yeasts endophytesresiding in thymus sp. was evaluated. during april to october 2011, symptomless and healthytissues of thymus sp. were collected. ...
Bacterial spot, caused by Xanthomonas spp., is one of the most important diseases tomato in Illinois. Field surveys were conducted during 2017–19 to assess occurrence bacterial spot commercial fields. Severity foliage and fruit infection was recorded, symptomatic samples collected from three-to-five cultivars three different farms each northern, central, southern regions ranged 0% 91% (average ...
The uptake of maltose and related sugars in Gram-negative bacteria is mediated by an ABC transporter encompassing a periplasmic component (the maltose-binding protein or MalE), a pore-forming membrane protein (MalF and MalG) and a membrane-associated ATPase (MalK). In the present study, the structure determination of the apo form of the putative maltose/trehalose-binding protein (Xac-MalE) from...
