مستخلص: | Plant viruses produce particular suppressors to antagonize the host defense response of RNA silencing to establish infection. Cucurbit chlorotic yellows virus (CCYV), a member of the genus Crinivirus of the family Closteroviridae , severely damages the production of economically essential cucurbits worldwide. Here, we used the attenuated zucchini yellow mosaic virus (ZYMV) vector ZAC to express individual coding sequences, including CP, CPm, P25, and P22, of a Taiwan CCYV isolate (CCYV-TW) to identify their possible roles as pathogenicity determinants. ZAC is an HC-Pro function mutant that lacks the ability of local lesion induction on Chenopodium quinoa leaves and induces mild mottling followed by recovery on its natural host zucchini squash plants. Only the recombinant expressing CCYV-TW P22 complemented the effect of ZAC HC-Pro dysfunction, causing more severe symptoms on zucchini squash plants and restoring lesion formation on C. quinoa leaves, with lesions forming faster than those generated by the wild-type ZYMV. This suggests that CCYV-TW P22 is a virulence enhancer. Sequence analysis of criniviral P22s revealed the presence of four conserved leucine residues (L Competing Interests: The author(s) declare no conflict of interest. |
