Project description:We isolated a bacterial identified as the genus of Mycetocola from the infected Flammulina velutipes samples collected from mushroom house in Hebei, North China. The stipe of F. velutipes appeared water-soaked, soften and browning after infected, finally, the whole plant rotten. The incidence of the disease can reach more than 80% in the serious areas, resulting in an obvious decline in the yield and quality of the F. velutipes. Furthermore, the pathogenic bacteria may occurrence in large areas by accumulated in the annual cultivation process. Therefore, the most effective measures to control this bacterial disease is screening resistant strains of F. velutipes with high yield and good agronomic traits. We obtained a white F. velutipes strain JK502 which has strong resistance to this bacterium by using the double-layer plate method combined with the sporozoite hybridization. JK501, which can early fruited, was screened using the same parent SH9 by multi spore hybridization. In order to investigate the differences of gene expression between the parent strain and the selected strains, we completed the transcriptome sequencing by Illumina HiSeq X system.
