Two new species of Cytospora (Diaporthales, Cytosporaceae) causing canker disease of Malusdomestica and M.sieversii in Xinjiang, China.
Apple tree canker is a serious disease caused by species of Cytospora. Xinjiang Uygur Autonomous Region is one of the most important apple-producing areas in China. However, losses due to apple Cytospora canker have seriously damaged the apple industry and affected the economic development of the apple growers in this region. In this study, we used morphological characteristics combined with multilocus phylogenetic analyses of the ITS, act, rpb2, tef1 and tub2 loci to identify isolates from apple (Malusdomestica) and wild apple (M.sieversii). As a result, C.hippophaopsissp. nov. from M.sieversii and C.shawanensissp. nov. from M.domestica were discovered and proposed herein. Pathogenicity tests were further conducted on 13 varieties of apple and wild apple, which confirmed C.hippophaopsis and C.shawanensis as canker pathogens. Meanwhile, C.hippophaopsis is generally more aggressive than C.shawanensis on the tested varieties of apple and wild apple.
