When plants are exposed to extreme temperature, stress-inducible proteins are highly induced and involved in subcellular defence mechanisms. Hsp70, one of stress-inducible proteins, functions as an ATP-dependent molecular chaperone in broad organisms to process such as the inhibition of protein denaturation, promotion of protein folding, and renaturation of(More)
The seven members of the 90-kDa heat shock protein (Hsp90) family encode highly conserved molecular chaperones essential for cell survival in Arabidopsis thaliana. Hsp90 are abundant proteins, localized in different compartments with AtHsp90.1-4 in the cytosol and AtHsp90.5-7 in different organelles. Among the AtHsp90, AtHsp90.1, is stress-inducible and(More)
Rice blast caused by Magnaporthe oryzae is a major disease in the paddy field and also a representative model system in the investigation of plant-microbe interactions. This study was undertaken to provide the quantitative evaluation method that specifically determines the amount of M. oryzae proliferation in planta. Real-time PCR was used as the detection(More)
Hsp90 proteins are essential molecular chaperones regulating multiple cellular processes in distinct subcellular organelles. In this study, we report the functional characterization of a cDNA encoding endoplasmic reticulum (ER)-resident Hsp90 from orchardgrass (DgHsp90). DgHsp90 is a 2742bp cDNA with an open reading frame predicted to encode an 808 amino(More)
• This study reports that Arabidopsis thaliana protein serine/threonine phosphatase 5 (AtPP5) plays a pivotal role in heat stress resistance. A high-molecular-weight (HMW) form of AtPP5 was isolated from heat-treated A. thaliana suspension cells. AtPP5 performs multiple functions, acting as a protein phosphatase, foldase chaperone, and holdase chaperone.(More)
Two strains of necrotrophic Alternaria brassicicola, Ab40857 and Ab42464, are virulent on Korean cabbage and several wild types of Arabidopsis thaliana. Interaction between Ab42464 and Col-0 was compatible, whereas interaction between Ab40857 and Col-0 was incompatible. The loss of defense, no death (dnd) 1 function abrogated the compatibility between(More)
Black spot caused by Alternaria brassicicola is an important fungal disease affecting cruciferous crops, including Korean cabbage (Brassica rapa subsp. pekinensis). The interaction between Arabidopsis thaliana and Alt. brassicicola is a representative model system, and objective estimation of disease progression is indispensable for accurate functional(More)
