| [molecular characteristics of dna-a of tomato leaf curl guangdong virus isolate g2]. | virus isolate g2 was isolated from tomato plants showing leaf curl symptoms in guangdong. the complete nucleotide sequence of g2 dna-a was determined to be 2744 nucleotides encoding six potential orfs, with two (av1 and av2) in virus sense and four (ac1, ac2, ac3 and ac4) in complementary sense. g2 dna-a has a typical characteristics of begomovirus genome organization. blast results showed that g2 dna-a belonged to the begomovirus of geminiviridae. pairwise comparisons of g2 dna-a with those of ... | 2005 | 15847162 |
| molecular characterization of a distinct begomovirus infecting allamanda cathartica in guangdong, china. | virus isolate g10 was obtained from diseased allamanda plants showing leaf curl symptoms in guangdong, china. the full-length nucleotide sequence of a dna-a-like molecule of g10 was cloned and sequenced; it comprises 2755 nucleotides and has a typical begomovirus genome organization with six conserved open reading frames. when compared with the dna-a sequences of other begomoviruses, the complete nucleotide sequence of dna-a of g10 had the highest sequence identity (81.2%) to tomato leaf curl gu ... | 2009 | 19609637 |
