Description A virue that induced yellow leaf spots which later coalesced
and became necrotic, vae ieolated from peanut (bacua
-1 in India and named peanut yellow apot'virus (PYSY).
PYSV was sap-transmisslbls to eleven epecles of Chenopodiaccao.
Lcpualnoeac, and Salanacsaa. The virus induced local leslona
in all tho host., Y. uaa a good local lesion host.
The infection In Fl&m -. Ylnnn rndLata and Y.
became ay~temic hen they uers maintained st
temperatures between 20 and 30'~. In thin sectlone of peanut
leaves rpherloal membrane-bound particlea of TO to 100 nm in
diameter were observed to occur in cluatera. Purlfled virus
Preparations contained five polypeptldeo of 90000. 54000.
44000. 40000 and 31000 dslton polypeptldca. Whan virus
particle^ were treated vlth Nanldet P 40, the polypeptides ware
removed with the exception of that of 31000 daltana In both
ELISA end western blot., PYSV did not react vlth antisera to
two tomato apotted wilt virus isolates. On the basis of these
properties. PYSV is regarded as a previously undeecribed virus
belon(linr to the tomato spotted wilt vlrus group.
