| molecular variation of satellite dna beta molecules associated with malvastrum yellow vein virus and their role in pathogenicity. | previous studies have found that the diversity of begomovirus-associated dna beta satellites is related to host and geographical origin. in this study, we have cloned and sequenced 20 different isolates of dna beta molecules associated with malvastrum yellow vein virus (myvv) isolated from malvastrum coromandelianum plants in different geographical locations of yunnan province, china. analyses of their molecular variation indicate that the satellites are clustered together according to their geo ... | 2008 | 18245261 |
| molecular characterization of a distinct begomovirus species and its associated satellite dna isolated from malvastrum coromandelianum in china. | a virus isolate y160 was obtained from malvastrum coromandelianum showing yellow vein symptoms in baoshan, yunnan province of china. the complete nucleotide sequence of dna-a was determined, it contains 2747 nucleotides and has typical genomic organization of a begomovirus. comparisons show that the total dna-a of y160 has the highest sequence identity (82.2%) with that of malvastrum yellow vein virus-[y47] (aj457824), while less than 77.6% identities are found when compared with the other begom ... | 2005 | 15965607 |
