| Abstract/Contents: | "Pythium iwayamai is a psychrophilic pathogen of turfgrasses and small grains. The mechanism by which this oomycete survives and infects plants under snow cover has not been studied in detail. We isolated RNA from P. iwayamai grown at 7 C and 19 C and in the presence and absence of 'Penncross' creeping bentgrass. RNA-seq was used to assemble and compare the transcriptomes under the various treatment combinations. These transcriptomes were also compared to those of the non-psychrophilic P. irregulare grown under the same conditions. P. iwayamai differentially expressed some proteins, including proteases and abc transporters at the lower temperature and in the presence of bentgrass. The proteases were not expressed at low temperatures in the absence of the bentgrass. Few glucosidases were differentially expressed and no antifreeze proteins were detected. Transcriptomes of P. irregular differed from those of P. iwayamai at both temperatures, with more proteases and glucosidases differentialy expressed at the higher temperature. Results suggest that increased protease activity may be an important component of the infection process of P. iwayamai at low temperatures and P. irregular at higher temperatures." |
