Increasing the expression level of purple acid phosphatases (PAPs), which hydrolyze organic phosphate to inorganic phosphate (Pi), is an important response to Pi starvation in plants. PAPs are widely distributed in eukaryotes like mammals and plants but distributed in limited microorganisms. A PAP-like protein named Pap9 from Burkholderia pyrrocinia CH-67 was isolated. The enzyme had optimal activity at atypical pH of 8.5 and temperature of 85°C. When pap9 was overexpressed in Arabidopsis thalia...

Abstract Autoinducers are indispensable for bacterial cell–cell communication. However, due to the reliance on culture-based techniques, few autoinducer-hydrolyzing enzymes are known. In this study, we characterized soil metagenome-derived unique enzymes capable of hydrolyzing 3-hydroxypalmitic acid methyl ester (3-OH PAME), an autoinducer of the plant pathogenic bacterium Ralstonia solanacearum. Among 146 candidate lipolytic clones from a soil metagenome library, 4 unique enzymes capable of hyd...

Ralstonia solanacearum is a soil-borne plant pathogen that infects more than 200 plant species. Its broad host range and long-term survival under different environmental stress conditions suggest that it uses a variety of mechanisms to protect itself against various types of biotic and abiotic stress. R. solanacearum produces a melanin-like brown pigment in the stationary phase when grown in minimal medium containing tyrosine. To gain deeper insight into the genetic determinants involved in mela...

Pseudomonas fluorescens pc78 is an effective biocontrol agent for soil-borne fungal diseases. We previously constructed a P43-gfp tagged biocontrol bacteria P. fluorescens pc78-48 to investigate bacterial traits in natural ecosystem and the environmental risk of genetically modified biocontrol bacteria in tomato rhizosphere. Fluctuation of culturable bacteria profile, microbial community structure, and potential horizontal gene transfer was investigated over time after the bacteria treatment to ...

Ralstonia solanacarum a plant pathogen which causes lethal wilt disease in members of solanceaous plant family. The pathogen can survive in soil for a long time under stress condition. In a stationary phase, we recognized that R. solanacearum GMI1000 wild type strain produced brown pigment in broth culture. The brown pigmentation was much faster in the liquid medium supplemented with tyrosine which is a melanin pigment precursor. To iden-tify genes responsible for melanin-like pigment production...

This study was conducted to evaluate tomato plant resistance against bacterial wilt by Ralstonia solanacearum using tomato cultivars or tomato breeding lines maintained in RDA-Genebank of Rural Development Administration and to select resistant tomato lines for breeding purpose. We evaluated the disease responses of a total of 13 cultivars and 39 breeding lines from RDA-Genebank using R. solanacearum SL341 strain, which is a representative strain in Korea. Tomato cultivar Hawaii 7996 and Moneyma...
