Colletotrichum falcatum, a concealed fungal ascomycete causes red rot, which is a serious disease in sugarcane. It infects economically important stalk tissues, considered as store house of sugar in sugarcane. The study is to find genetic complexities of C. falcatum in establishing this as a stalk infecting pathogen and to decipher the unique lifestyle of this pathogen using NGS technology. We report the draft genome of C. falcatum of about 48.16 Mb in size with 12,270 genes. The genome sequences were compared with other fungal species which revealed that C. falcatum is closely related to C. graminicola and C.sublineola the causal organisms of anthracnose in maize and sorghum. These results brought a new revelation to explore the lifestyle of this unique pathogen which is specialized to infect sugarcane stalk tissues in detail.
胶孢炭疽菌是一种隐匿的子囊真菌，可引发甘蔗赤腐病，这是甘蔗的一种严重病害。它侵染甘蔗中作为糖分储存库的重要经济茎杆组织。本研究旨在探寻胶孢炭疽菌作为茎杆侵染病原菌的遗传复杂性，并利用二代测序技术解析该病原菌独特的生活方式。我们报道了胶孢炭疽菌的基因组草图，其大小约为48.16 Mb，含有12270个基因。将该基因组序列与其他真菌物种进行比较后发现，胶孢炭疽菌与玉米炭疽病和高粱炭疽病的病原菌禾生炭疽菌及亚线炭疽菌密切相关。这些结果为详细探究这种专门侵染甘蔗茎杆组织的独特病原菌的生活方式带来了新的启示。
