| Abstract: | Antiviral Protiens (AVPs) named CAP-I and CAP-II purified from the leaves of Chenopodium album cv Pusa Bathura-1 indaced systemic against tobacco mosaic virus (TMV) and sunnhemp rosette virus (SRV) in both hypersenstitive as well as systemic hosts. An increased accumulation of two polypeptides (~17 kDa and ~26 kDa) was observed in untreated upper leaves of Cyamopsis tetragonoloba plants whose basal leaves were treated with CAP-I/CAP-II. Both AVPs exhibited ribosomal RNA N-glycosidase activity on 28S rRNA of tobacco leaves and also caused in vitro degradation of TMV RNA. It is suggested that the CAP-I and –II are multi-functional and may be acting at multiple levels to ensure maximum possible inhibition of viral infection. |
