molecular characterization of two distinct begomoviruses from papaya in china. | six papaya samples showing downward leaf curling were collected in guangdong and guangxi provinces, china. the result of tas-elisa showed they were all infected by geminiviruses. comparison of partial dna-a sequences reveals that these virus isolates can be classified into two groups. group i includes isolates g2, g4, g5, g28 and g29 from guangxi province, while isolate gd2 from guangdong province belongs to group ii. the complete dna-a sequence of g2 and gd2 were characterized. sequence compari ... | 2004 | 15550769 |
molecular characterization of a novel monopartite begomovirus isolated from pouzolzia zeylanica in china. | the complete genome sequence of a monopartite begomovirus isolate ty01 was obtained from diseased pouzolzia zeylanica plants exhibiting golden mosaic symptoms in baise, guangxi province, china. it consisted of 2723 nucleotides (nt) and encoded two orfs (cp and av2) in the virion-sense dna and five orfs (ac1-ac5) in the complementary-sense dna. compared with the dna-a sequences of other begomoviruses, it has the highest (78.5 %) nucleotide sequence identity with ageratum yellow vein virus (ayvv) ... | 2013 | 23462887 |
