molecular characterization of a new whitefly-transmissible bipartite geminivirus infecting tomato in panama. | the nucleotide sequence of infectious clones of a tomato-infecting geminivirus from panama [named tomato leaf curl virus (tolcv-pan) because of symptoms produced in infected tomato (plant stunting and mild leaf curling)] was determined. tolcv-pan has a bipartite genome (dnas a and b) and computer analysis showed that the genome resembles that of other bipartite, whitefly-transmitted geminiviruses. dna a (2584 nt) and b (2542 nt) have little sequence homology other than within the common region. ... | 1998 | 9780034 |
