An investigation of tomato extensin.
Plant dcfcncr rcsponscs to pathogcn clicitation, plant ccll growth and dcvclopmcnt arc complex and highly integrated pmcesses. Intcraction betwecn host plant and pathogcn result in significant differences in defence gcnc cxprcssion.

متن کاملInvestigating the Role of Extensin Proteins in Poplar Biomass Recalcitrance
The biological conversion of cellulosic biomass to biofuel is hindered by cell wall recalcitrance, which can limit the ability of cellulases to access and break down cellulose. The purpose of this study was to investigate whether hydroxyproline-rich cell wall proteins (extensins) are present in poplar stem biomass, and whether these proteins may contribute to recalcitrance. Three classical exte...
متن کاملRole of the extensin superfamily in primary cell wall architecture.
Nearly two centuries of progress have established the major components of the plant cell wall, a composite that includes interpenetrating networks of cellulose (Payen, 1838; Schulze, 1891), microfibrils (Frey-Wyssling et al., 1948; Preston et al., 1948), pectin (Braconnot, 1825) and lignin (Payen, 1838). However, only over the last five decades has a relatively minor hydroxyproline-rich structu...
متن کاملPurification and Partial Characterization of Tomato Extensin Peroxidase.
Early plant defense response is characterized by elevation of activity of peroxidases and enhanced insolubilization of hydroxyproline-rich glycoproteins, such as extensin, in the cell wall. The insolubilization process (cross-linking between soluble extensin precursor molecules) is catalyzed by extensin peroxidases. We have ionically eluted extensin peroxidases from intact water-washed suspensi...
متن کاملRhizobia modulate root-hair-specific expression of extensin genes.
Three cDNAs (ext3, ext127, and ext26), originally isolated by differential screening from a root-hair cDNA library of Vigna unguiculata, were found to encode extensin-like cell wall proteins. Transcripts homologous to these cDNAs were only detected in root hairs where mRNA levels decreased 1 day after inoculation with rhizobia. This coincided with the onset of root-hair deformation, the first m...
