I$#"!;3'!( *#',!#*( ;3$59((GFLV) (a member of the genus J!");3$59, family G!4);3$37#!) is responsible for the for an economic disease of grapevines throughout the world (Andret-Link !%( #,C02004). It is naturally transmitted by the soil nematode K3"-3'!&#(3'7!L !"#$%!$%&!'()$!*+($&#,!-&$&+.#,#,/!$+),0.#00#(,!0*&'#1'#$2!34'%&55&,6&+/&+ !%( #,C02011). Symptoms of the disease include fanleaf, mosaic, shortened internodes and in chromogenic strains severe leaf chlorosis. GFLV naturally infects grapevine (Andret-Link !%(#,C02004) as well as Bermuda grass and knotweed in Iran (Izadpanah !%( #,C0 2003a, 2003b). Despite ample information on molecular variability of GFLV isolates from grapevine, little is known about molecular aspects of this virus from other hosts. In this paper, we report new weed hosts of GFLV and . molecular variability of GFLV isolates from non-vitis hosts.
