Proteomic analysis of Puccina striiformis f. sp. tritici (Pst) during uredospore germination
European Journal of Plant Pathology 144 (1), 121-132
Abstract: Puccinia striiformis f. sp. tritici (Pst), the causal agent of wheat stripe rust, is an obligate pathogen that causes significant yield losses worldwide. In order to profile the change of the proteome during uredospore germination of Pst, proteins from uredospores and germtubes (germlings) were isolated and quantified by iTRAQ (isobaric tag for relative and absolute quantitation) technology. Among the 1548 proteins identified, there were 64 and 54 proteins up- and down-regulated during uredospore germination respectively. Proteins involved in catabolic process, energy production and transport were found to be specially accumulated in germlings, which was an indication of metabolic transition from dormancy to germination. While, proteins involved in protein metabolic process were largely down-regulated, suggesting fewer proteins were needed for uredospore germination. Additionally, a number of down-regulated proteins exhibited increasing mRNA level during germination, suggesting relative less correlation between proteins and mRNAs in dormant uredospores.
