Genomic Resources of Four Colletotrichum Species ( C. fioriniae, C. chrysophilum, C. noveboracense and C. nupharicola ) Threatening Commercial Apple Production in the Eastern U.S

The genus includes nine major clades with 252 species and 15 major phylogenetic lineages, also known as species complexes. spp. are one of the top fungal plant pathogens causing anthracnose and pre- and post-harvest fruit rots worldwide. Apple orchards are imperiled by devastating losses from apple bitter rot ranging from 24 to 98%, which is a serious disease caused by several species of . Bitter rot is also a major postharvest rot disease with leading to 2 - 14 % of unmarketable fruit in commercial apple storages. Dominant species causing apple bitter rot in the Mid-Atlantic U.S. are from the species complex (CASC), and and from the species complex (CGSC). is the dominant species causing apple bitter rot in the Northeastern and Mid-Atlantic U.S. was first identified on banana and cashew but has been recently found as the second most dominant species causing apple bitter rot in the Mid-Atlantic. As the third most dominant pathogen, MB 836581 was identified as a novel species in the CGSC causing apple bitter rot in the Mid-Atlantic. is a sister group to and , also causing bitter rot on apple. We deliver resources of 10 new genomes including two isolates of , three isolates of , three isolates of and two isolates of collected from apple fruit, yellow waterlily and .
