ABSTRACT Proliferative cell nuclear antigen (PCNA), a conserved plant protein as well as an important replication factor, is induced in response to geminivirus infection in the resting cells of the phloem tissues. The biochemical role of PCNA in rolling circle replication (RCR) of geminivirus DNA has not been explored in detail. The initiation of RCR of the bipartite genome of a geminivirus, Indian mung bean yellow mosaic virus (IMYMV), is mainly controlled by viral protein Rep (or AL1 or AC1). The role of host PCNA in RCR of IMYMV was revealed by studying the physical and functional interactions between recombinant PCNA and recombinant IMYMV Rep. Pea nuclear PCNA as well as recombinant pea PCNA showed binding to recombinant Rep in experiments involving both affinity chromatography and yeast two-hybrid approaches. The contacting amino acid residues of PCNA seemed to be present throughout a wide region of the trimeric protein, while those of Rep appeared to be localized only in the middle part of the protein. The site-specific nicking-closing activity and the ATPase function of IMYMV Rep were impaired by PCNA. These observations lead to interesting speculations about the control of viral RCR and dynamic profiles of protein-protein interactions at the RCR origin of the geminiviruses.

Seven complete genomes and 64 coat protein gene sequences belonging to Bean yellow mosaic virus (BYMV) isolates from different continents were examined for evidence of genetic recombination using six different recombination-detection programs. In the seven complete genomes and a single complete genome of the related virus Clover yellow vein virus (ClYVV), evidence for eight recombination patterns was found by four or more programs, giving firm evidence of their presence, and five additional recombination patterns were detected by three or fewer programs, giving tentative evidence of their occurrence. When the nucleotide sequences of 64 BYMV and one ClYVV coat protein genes were analyzed, three firm recombination patterns were detected in 21 isolates (32%). With another six isolates (9%), tentative evidence was found for three further recombination patterns. Of the 19 firm or tentative recombination patterns detected within and between strain groups of BYMV, and with ClYVV, 12 involved a generalist group of isolates as a parent but none of the other BYMV groups acted as parents more than six times. These findings suggest that recombination played an important role in the evolution of BYMV strain groups that specialize in infecting particular groups of domesticated plants.

A total of nine black gram genotypes were tested for yellow mosaic virus (YMV) resistance along with other nine biometrical traits. The genotypes VBN 4, KKB-14-015, KKB-14-45 and KKB-14-022 exhibited complete resistance to YMV in field screening. From the molecular characterization, out of 42 SSR markers studied, 15 SSR markers expressed polymorphism. The PIC values ranged from 0.37 (for SSR marker CEDG 024) to 0.79 (CEDG 154) with an average of 0.63. From the cluster analysis, YMV resistant genotypes KKB-14-045 and KKB-14-015 were located on clusters 6 and 7 and the susceptible but agronomic desirable genotypes IC 343943 and IC 436656 were located on cluster 3 which showed the diverse nature of these genotypes. Hence combinations viz., IC 343943 x KKB-14-015, IC 343943 x KKB-14-045, IC 436656 x KKB-14-015 and IC 436656 x KKB-14-045 would be ideal to produce desirable recombinants for YMV resistance breeding in black gram.
