| [genomic characterization of tomato yellow leaf curl china virus and its associated satellite dna infecting tobacco in guangxi]. | the virus isolates g102 and g103 were collected from tobacco showing leaf curl symptoms in jingxi, guangxi province. a 0.5kb fragment was obtained by pcr using primers specific to geminivirus genome. the nucleotide sequence identity of the partial dna-a sequence between the two isolates was over 99%. the complete dna-a sequence of g102 was determined to be 2728 nucleotides. comparisons showed that the dna-a of g102 had the highest sequence identity (96.5%) with that of tomato yellow leaf curl ch ... | 2006 | 16933601 |
