Abstract

The cassava common mosaic virus (CMV) is a pathogen that affects cassava plants. The complete genome sequence of a CsCMV isolate was obtained from cassava plants in São Paulo state, Brazil. Subsequent field surveys across multiple counties revealed a high prevalence of CsCMV, ranging from 67 to 100%. Phylogenetic analysis demonstrated two distinct genetic groups of CsCMV isolates in São Paulo, with the Brazilian isolate closely related to isolates from the United States and China. Considering that cassava is propagated vegetatively, the high incidence of CsCMV highlights the need to establish programs to obtain virus-free propagation materials.

木薯普通花叶病毒在木薯植物中的高发病率和巴西一个独特分离株的完整基因组序列

木薯普通花叶病毒（CMV）是一种影响木薯植物的病原体。从巴西圣保罗州的木薯植株中获得了 CsCMV 分离物的完整基因组序列。随后在多个县进行的实地调查显示，CsCMV 的流行率很高，从 67% 到 100% 不等。系统发育分析表明，圣保罗州的 CsCMV 分离物有两个不同的基因组，巴西的分离物与美国和中国的分离物关系密切。考虑到木薯是无性繁殖，CsCMV 的高发病率凸显了制定计划以获得无病毒繁殖材料的必要性。

期刊介绍： Tropical Plant Pathology is an international journal devoted to publishing a wide range of research on fundamental and applied aspects of plant diseases of concern to agricultural, forest and ornamental crops from tropical and subtropical environments.  Submissions must report original research that provides new insights into the etiology and epidemiology of plant disease as well as population biology of plant pathogens, host-pathogen interactions, physiological and molecular plant pathology, and strategies to promote crop protection. The journal considers for publication: original articles, short communications, reviews and letters to the editor. For more details please check the submission guidelines. Founded in 1976, the journal is the official publication of the Brazilian Phytopathology Society.
