Description 29-33
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.
