Responses of seven plant species to inoculation with eight different isolates of Bean yellow mosaic virus (BYMV) and one of Clover yellow vein virus (ClYVV).

Leaves were inoculated with infective sap. Samples from inoculated and tip leaves were tested by ELISA for BYMV, ClYVV and potyviruses in general.aLocations where isolates were collected from: ClYVV, New South Wales (NSW); LMBNN, Mt. Barker, Western Australia (WA); AR93C, Arthur River, WA; MD5 and MD7, Medina, WA; GB17A, Gibson, WA; ES11A, Esperance, WA; LP, South Perth WA.bCoded symptom descriptions: B, bunchy new growth; BP, black pods; DR, leaf drop; LCS, local chlorotic spots; LD, leaf distortion; LMCS, local mild chlorotic spots; LNS, local necrotic spots; M, mosaic; MM, mild mosaic; MSS, mild necrotic stem streaking; MVC, mild local vein clearing; NI, not infected; NSH, local necrotic spots with halo; nt, not tested; PSN, partial necrotic stem streaking (no infection in uninoculated leaves); R, reddening; SC, shepherds crook appearance (i.e. bending over and apical tip necrosis); SS, necrotic stem streaking; SSS, severe necrotic stem streaking leading to plant death; SCS, systemic chlorotic spots; SM, severe mosaic; SN, severe necrosis of uninoculated leaves and new growth; St, stunting; SVC, systemic vein clearing; VC, localized vein clearing; Y, yellowing.cDenotes that the initial round of inoculations failed to infect plants of this species, and due to a lack of seed the inoculations were not repeated.dDenotes that two rounds of inoculation failed to infect L. angustifolius cv. Mandelup. Further testing involving sap, aphid and graft inoculations are required.
