Project description:Expression diversity of P. ramorum isolates belonging to the NA1 clonal lineage growing on solid CV8 was examined. It was found that although all the analyzed isolates belonged to a single clonal lineage, expression patterns were distinctive between isolates originating from coast live oak and California bay laurel. Global expression patterns of 13 isolates originating from coastal live oak and California bay laurel was investigated. No biological replicates were generated. The sequenced strain Pr102 was included. Gene models Phytophthora ramorum v1.0 were used to construct NimbleGen 72K x4 custom arrays.
Project description:Deep sequencing of small RNAs from three Phytophthora species, P. infestans, P. ramorum and P. sojae, was done to systematically analyze small RNA-generating components of Phytophthora genomes. We found that each species produces two distinct small RNA populations that are predominantly 21- or 25-nucleotides long. We present evidence that 25-nucleotide small RNAs are short-interfering RNAs that silence repetitive genetic elements. In contrast, 21-nucleotide small RNAs are associated with inverted repeats, including a novel microRNA family, and may function at the post-transcriptional level. Phytophthora ramorum mycelium small RNAs were sequenced and aligned to the P. ramorum genome for analysis. *Raw data files (fastq) are unavailable for this study.
