We present the genome assembly of Ralstonia pickettii K-288 (ATCC 27511), consisting of 27 contigs placed into a single scaffold. This 4.76-Mbp genome has 64.0% G+C content and 4,425 coding sequences. Because this is the type strain, inclusion of its data set among other Ralstonia genomes should provide a historical genomic perspective.
Microbe-based biocontrol applications hold the potential to become an efficient way to control plant pathogen disease outbreaks in the future. However, their efficiency is still very variable, which could be due to their sensitivity to the abiotic environmental conditions.Here, we assessed how environmental temperature variation correlates with ability of Ralstonia pickettii, an endophytic bact...
We investigated the genetic diversity, extent of recombination, natural selection, and population divergence of Ralstonia solanacearum samples obtained from sources worldwide. This plant pathogen causes bacterial wilt in many crops and constitutes a serious threat to agricultural production due to its very wide host range and aggressiveness. Five housekeeping genes, dispersed around the chromos...
Ralstonia solanacearum is an important etiological agent that can cause serious bacterial wilt in a very wide range of potential host plants, including ginger. Here, we report the complete genome sequence of R. solanacearum SD54, a race 4 biovar 4 (R4B4) strain from a diseased ginger plant in China.

one of the best strategies to control bacterial wilt caused by ralstonia solanacearum (smith) is generally based on breeding resistant cultivars. the information obtained from the expression of plant defense genes will provide new insight for improving plant resistance against pathogens. this study was to identify inducible genes under defense no death (dnd) reaction of tobacco (nicotiana tabac...
باکتری ralstonia solanacearum باکتری خاکزی است که از طریق ریشه به بیش از 200 گونه گیاهی از جمله گیاهان مدل taliana arabidopsis و medicago truncatula حمله کرده و باعث مسدود شدن آوندهای گیاهی از یک طرف و از طرف دیگر هضم پروتئین ها و آنزیم های کلیدی سلول گیاهی از طریق سیستم ترشحی بیماریزایی نوع سوم می شود که نتیجه آن پژمردگی و از بین رفتن گیاهان است. در این تحقیق از گیاهان مقاوم و حساس m. truncatu...
secondary metabolism in the plant pathogen Ralstonia solanacearum.

بیماری پژمردگی باکتریایی ناشی از باکتری ralstonia solanacearum از اهمیت نسبی روی سیب زمینی در استان همدان برخوردار هستند.در این تحقیق تنوع بیماریزایی و ویژگیهای فنوتیپی این باکتری مورد بررسی قرار گرفت. بدین منظوردر بهار و تابستان سال 1389 نمونههای غده و بوته مشکوک به بیماری از مزارع استان همدان گردآوری شدند. از نمونههای گردآوری شده مجموعا 78 استرین باکتری r. solanacearum پس از کشت روی محی...
Bacterial biofilms are associated with secondary gold grains from two sites in Australia. 16S ribosomal DNA clones of the genus Ralstonia that bear 99% similarity to the bacterium Ralstonia metallidurans-shown to precipitate gold from aqueous gold(III) tetrachloride-were present on all DNA-positive gold grains but were not detected in the surrounding soils. These results provide evidence for th...
