This article provides a brief overview of some of the major concepts and molecular features of plant and animal innate immune systems. The rice pathogen recognition receptor, XA21, confers resistance to Xanthomonas oryzae pv. oryzae strains producing the AvrXa21 elicitor. Xa21 codes for a receptor-like kinase consisting of an extracellular leucine-rich repeat domain, a transmembrane domain, and...
In vivo and in vitro effects of secondary metabolites against Xanthomonas campestris pv. campestris.
Brassica rapa is a crucifer that is grown worldwide, mainly as a vegetable. The quality of B. rapa crops is highly affected by the disease caused by the bacteria Xanthomonas campestris pv. campestris (Xcc). Glucosinolates and phenolic compounds can confer resistance to Brassica crops against pests and diseases, but few works have been done to evaluate their role in Xcc resistance. The objective...
Waste residual molasses, a non-edible portion produced during the processing of sugarcane juice for the preparation of molasses, may be an alternative low-cost renewable substrate to the pricey food-grade molasses for xanthan production. Systematic strategies were applied to improve xanthan production with a newly isolated indigenous strain Xanthomonas campestris originated from Tezpur, Assam. ...
BACKGROUND Rice plant diseases play a major role as biological constraints on production. One of such rice disease is bacterial leaf blight, caused by Xanthomonas oryzae pv. Oryzae (Xoo). The diffusible signal factor (DSF) synthesized by Xoo has a major role in virulence to rice plant. The DSF synthase RpfF protein, which is related to crotonase superfamily is responsible for the maintaining co...
Chromosomal DNA from group I Pseudomonas species, Azotobacter vinelandii, Azomonas macrocytogens, Xanthomonas campestris, Serpens flexibilis, and three enteric bacteria was screened for sequences homologous to four Pseudomonas aeruginosa alginate (alg) genes (algA, pmm, algD, and algR1). All the group I Pseudomonas species tested (including alginate producers and nonproducers) contained sequenc...
باکتریهای جنس Xanthomonas از مهم ترین باکتریهای بیماریزای گیاهان زراعی بوده و از عوامل مهم فساد پس از برداشت و خسارت اقتصادی می‌باشند. در این مطالعه 71 نمونه از خاک کشتزارهای حومة شهرهای ری و کرج جمع‌آوری شد. غربالگری باکتریها بر روی محیط نیمه‌انتخابی SX agar، انجام آزمونهای ریخت‌شناسی و بیوشیمیایی و بررسی دو شاخص ویژة ویرولانس منجر به جداسازی تعدادی جدایة X. campestris در میان باکتریهای رشد ی...
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 ...
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...
