Transcriptome sequence resource for the cucurbit powdery mildew pathogen Podosphaera xanthii [PDF]

Scientific Data, 2019
AbstractPodosphaera xanthiiis the main causal agent of cucurbit powdery mildew in Southern Italy. Illumina sequencing of mRNA from twoP. xanthiiisolates of opposite mating types (MAT1-1andMAT1-2) and their sexual cross was used to obtain a detailedde novoTrinity-based assembly of the transcriptome of the fungus.
