“…The immunity of TVu 470 is governed by a single, dominant gene (Sterk and De Jager, 1987). The immunities of 'Arlington' and TVu 1948 are reported to be based on one dominant and one recessive gene, respectively (Kiefer et al, 1984;Patel, 1982). We could confirm this using our Nigerian CPMV-isolate.…”

“…The immunity of Arlington seems not to be based on a single recessive gene , like that of cowpea accession TVu 1948 (Patel, 1982). The latter line, therefore, possesses a third type of immunity to CPMV.…”

SUMMARYInfection of a cowpea line by cowpea severe mosaic virus (CPSMV) was inhibited by cowpea mosaic virus (CPMV) even though the plants were immune to CPMV. The inhibition was dose-dependent and was complete if CPMV was added to the inoculum in a 50-fold excess over CPSMV. Isolated CPMV RNA inhibited infection by CPSMV or by isolated CPSMV RNA. CPMV particles devoid of RNA (top component), u.v.-inactivated but intact CPMV particles or u.v.-inactivated CPMV RNA did not inhibit infection by CPSMV. Bottom component particles of CPMV, but not middle component particles, inhibited CPSMV to the same extent as unfractionated CPMV. These findings strongly suggest that the interference is not due to competition between the particles or the RNAs of the two viruses for infectible sites. It may be that CPMV infects cells of the 'immune' host subliminally and that the inhibition is associated with replication of at least bottom component RNA of CPMV.

“…In Vigna unguiculata L . Walp ., the allele MVN-1 controls the hypersensitive resistance to the cowpea mosaic virus strain CPMV LL and the lethal necrosis to the CPMV-TN strain (Patel, 1982) . These results suggest a strong interaction between hypersensitive reactions and systemic necrosis.…”

Genetic analysis of broad spectrum resistance to potyviruses using doubled haploid lines of pepper (Capsicum annuum L.)

Genetic analysis of resistance to PVY in androgenetic doubled haploid lines, Fl, F2 and backcross progenies of the Mexican pepper line, CM 334 (Capsicum annuum L.), was performed . Three reaction types were observed when seedlings were inoculated with several PVY strains of different pathotypes and with an American PeMV strain . Resistant genotypes never showed systemic symptoms although some individuals sporadically developed necrotic local lesions on inoculated cotyledons . Susceptible genotypes exhibited either a typical systemic mosaic or a systemic necrosis that caused the death of the inoculated seedlings . Segregation analyses indicated that resistance to pepper potyviruses in CM 334 is conferred by two genes . The first one, tentatively named Pr4, is dominant and confers the resistance to all now known pathotypes of PVY and to PeMV The second one, tentatively named pry, is recessive ; it confers only the resistance to common strains of PVY The systemic necrotic response is conferred by an independent dominant gene, tentatively named Pnl . 231
