Abstract

Two monopartite begomoviruses were isolated from Pouzolzia zeylanica (L.) Benn. plants showing yellow mosaic symptoms in Gaoyao, Guangdong Province, China (GD1) and in Phu Tho, Vietnam (VN), respectively. A comparison of the complete genome sequence of GD1 (2,739 nucleotides (nt)) with VN (2,741 nt) indicated that they shared 86.2 % nt sequence identity. GD1 and VN shared the highest nucleotide sequence identity at 86.7 % and 91.4 % respectively, with isolate TY01 of pouzolzia golden mosaic virus (PGMV-TY01), another begomovirus isolated from P. zeylanica . Phylogenetic analysis revealed that GD1, VN, and PGMV-TY01 were members of a distinct begomovirus clade. Based on the ICTV guidelines for begomoviral species demarcation, GD1 belongs to a new begomovirus species, for which the name Pouzolzia yellow mosaic virus is proposed. Likewise, VN represents a previously unreported strain of PGMV. Recombination analysis predicted that VN was a recombinant between PGMV-TY01 and ageratum yellow vein China virus isolate G13 (AYVCNV-G13), and that PGMV-TY01 and VN were likely the parents of GD1 through recombination with allamanda leaf curl virus isolate G10 (AlLCV-G10), a begomovirus endemic to Guangdong Province of China.
