molecular characterization of squash leaf curl yunnan virus, a new begomovirus and evidence for recombination. | virus isolate y23v, obtained from squash showing leaf curl symptoms in yunnan, china, was readily differentiated from four studied chinese begomovirus isolates in reactions with a set of monoclonal antibodies raised against begomoviruses. the complete nucleotide sequence (2714 nts) of the dna-a-like molecule of y23v was determined. the dna-a of y23v is most closely related to that of tomato yellow leaf curl thailand virus-[1] (tylcthv-[1]) (84% sequence identity). however, the ac1 and ac4 gene o ... | 2003 | 14551824 |
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 |
occurrence and distribution of pepper veinal mottle virus and cucumber mosaic virus in pepper in ibadan, nigeria. | viral diseases constitute obstacles to pepper production in the world. in nigeria, pepper plants are primarily affected by pepper veinal mottle virus (pvmv), cucumber mosaic virus (cmv), pepper leaf curl virus (tlcv), tobacco mosaic virus (tmv), pepper mottle virus (pmv) and a host of other viruses. the experiment was carried out with a diagnostic survey on the experimental field of the national horticultural research institute, ibadan, nigeria and on pepper farms in six local government areas w ... | 2012 | 22495040 |
microarray analyses for identifying genes conferring resistance to pepper leaf curl virus in chilli pepper (capsicum spp.). | pepper leaf curl virus (peplcv) is a serious threat to pepper (capsicum spp.) production worldwide. molecular mechanism underlying pepper plants response to peplcv infection is key to develop peplcv resistant varieties. in this study, we generated transcriptome profiles of peplcv resistant genotype (bs-35) and susceptible genotype (ivpbc-535) after artificial viral inoculation using microarray technology and detail experimental procedures and analyses are described. a total of 319 genes differen ... | 2016 | 27556012 |
