The Arabidopsis transcription factor WRKY27 influences wilt disease symptom development caused by Ralstonia solanacearum.
WRKY transcription factors play a key role in modulating the plant defense transcriptome. Here we show that the Arabidopsis mutant wrky27-1, which lacks a functional WRKY27 transcription factor, showed delayed symptom development in response to the bacterial wilt pathogen Ralstonia solanacearum. Additionally, wrky27-1 plants did not express PR marker genes upon infection, as also observed in re...
متن کاملBiological control of potato bacterial wilt caused by Ralstonia solanacearum in Ethiopia: Determination of biovars of Ralstonia solanacearum
Ralstonia solanacearum is a very destructive pathogen that causes wilt in potato and many other solanacean crops in Ethiopia. In order to select effective antagonistic biocontrol agents for R. solanacearum strains, it is necessary to characterize the population of pathogenic strains. Therefore, 62 strains collected from wilted potato, tomato and pepper plants and potato tubers from the major po...
متن کاملRecent Trends in Control Methods for Bacterial Wilt Diseases Caused by Ralstonia solanacearum
Previous studies have described the development of control methods against bacterial wilt diseases caused by Ralstonia solanacearum. This review focused on recent advances in control measures, such as biological, physical, chemical, cultural, and integral measures, as well as biocontrol efficacy and suppression mechanisms. Biological control agents (BCAs) have been dominated by bacteria (90%) a...
متن کاملSoil Amendments and Water Moisture on the Control of Tomato Bacterial Wilt Caused by Ralstonia Solanacearum
Bacterial wilt is one of the most severe tomato diseases worldwide and Ralstonia solanacearum is determined to be the pathogen responsible for its spread. Soil amendments such as calcium cyanamide and herb residues have both been proved to be high potential for tomato bacterial wilt control. Disinfection effect and heat generated during the decomposition processes of calcium cyanamide and herb ...
متن کاملFirst Report of Bacterial Wilt Caused by Ralstonia solanacearum Biovar 2 Race 1 on Tomato in Egypt
This study aims to isolate and identify the causal pathogen of tomato bacterial wilt in Egypt. In 2008, tomato plants showing typical symptoms of bacterial wilt disease with no foliar yellowing were observed in Minia, Assiut and Sohag governorates, Egypt. When cut stems of symptomatic plants were submerged in water, whitish ooze was evident and longitudinal sections showed a brown discoloration...
