ABSTRACT
BACKGROUND:
Cotton leaf curl Multan virus (CLCuMuV) is a Whitefly Transmitted Geminivirus (WTG) endemic to the India subcontinent and is notorious as a causal agent of cotton leaf curl disease (CLCuD), a major constraint to cotton production in south Asia. We found CLCuMuV infecting Hibiscus rosa-sinensis in Guangzhou, China in 2006. The spread and evolution of the invading CLCuMuV were monitored in the following nine years.FINDINGS:
CLCuMuV spread rapidly in the last nine years and became established in Southern China. It infects at least five malvaceous plant species, H. rosa-sinensis, H. esculentus, Malvaiscus arboreus, Gossypium hirsutum and H. cannabinus. Complete nucleotide sequences of 34 geographically and/or temporally distinct CLCuMuV isolates were determined and analyzed together with six other publicly available genomes of CLCuMuV occurring in China. The 40 CLCuMuV isolates were found to share > 99 % nucleotide sequence identity with each other. In all cases tested, the CLCuMuVs were associated with a CLCuMuB. The 36 CLCuMuBs (30 sequenced by us) shared > 98 % nucleotide sequence identity.CONCLUSION:
The high genetic homogeneity of CLCuMuV and CLCuMuB in China suggests the establishment of them from a single founder event.
