“…Goodrick et al (1991) reported two recessive genes responsible for soybean resistance to Cowpea chlorotic mottle virus -CpCMV. Silva et al (2004) assessed the inheritance to a new strain of Soybean mosaic virus (SMV) that broke the resistance of the soybean cultivar FT-10 in Brazil and identified an alternative allele for the Rsv1 locus, named as Rsv1 d .…”

“…Thus, the serological test enabled us to confirm the observed genetic resistance to natural infections by PVY and EPMV to be symptomless tolerance (partial resistance). The absence of systemic symptom expression in the presence of virus infection, with a positive serological test, in a crop plant was referred by Silva et al (2004) and Sharma et al (2008) as genetic tolerance while they described the reverse case as genetic susceptibility. Visible symptom expressions, including decreased plant vigor and growth resulting from virus infections are the common causes for biomass yield losses in crop plants (Fereres et al 1993;Fereres 2000).…”

The productivity and marketable quality of hot pepper (Capsicum annuum var. annuum L.) are low in tropical regions mainly due to virus infections and lack of effective virus management strategies. The absence of effective virus management strategies could be attributed to lack of information on virus vectors and host resistance. Parental (P 1 and P 2 ) and progeny (F 1 , B 1 , B 2 and F 2 ) generations of five hot pepper crosses were grown in Ethiopia at three sites (Bako, Hawasa and Melkasa) to monitor number and species of potential aphid vectors, disease incidence levels with regards to natural infections by Potato virus Y (PVY) and Ethiopian pepper mottle virus (EPMV) complex, and to determine genetic tolerance of the crop to the viruses. Disease incidence was assessed before the flowering stage of the crop plants using visible disease symptoms due to infections by PVY and EPMV. The serological tests revealed presence of symptomless genotypes of the crop to the virus infections. Aphid species potentially transmitting the viruses, such as Acyrthosiphon pisum (Harris), Aphis fabae (Scopoli), and Myzus persicae (Sulzer), were identified from specimens caught by yellow water traps. The highest number of aphids from yellow water traps was recorded at a dense foliage growth stage of the crop at Melkasa. Highly significant variation was observed among generations of the five crosses in response to infections by PVY and EPMV complex. The most susceptible parents had the levels of disease incidences ranging from 80 to 90%, whereas their progenies had only below 30% incidence levels. The most tolerant parent remained symptomless to the natural infections of PVY-and EPMV-complex. Incidence levels in progenies of a cross from the most susceptible and tolerant parents remained below 20%. Based on serological test, the proportion of PVY-positive plants ranged from 0 to 75% and of EPMV-positive plants from 0 to 25%, with 0 to 17% co-infection by the two viruses. Availability of virus sources in the vicinity, efficiency of aphids in vectoring, weather conditions during the growth period, genetic tolerance and the growth stage of the crop affected natural infection by PVY-and EPMV-complex. Exploitation of the genetic potential of introduced elite genotypes and their progenies along with breeding elite local cultivars for resistance Electronic supplementary material The online version of this article (and excluding aphid vectors at young (seedling) stage of the crop plants could be helpful for minimizing losses in yield and quality of hot pepper due to infections by PVY-and EPMV-complex.

“…13, was first recognized in soybean line “PI96983” (Kiihl & Romeu, 1979). This locus was repeatedly identified in other soybean cultivars, including “Corsica” ( Rsv1‐c ), “FT‐10” ( Rsv1‐d ), “Suweon 97” ( Rsv1‐h ), “Kwanggyo” ( Rsv1‐k ), “Marshall” ( Rsv1‐m ), “PI507389” ( Rsv1‐n ), “Raiden” ( Rsv1‐r) , “LR1” ( Rsv1‐s ), “Ogden” ( Rsv1‐t ) and “York” ( Rsv1‐y ) (Chen et al, 2001; Chen, Buss, Roane, & Tolin, 1991; Chen, Buss, Tolin, Gunduz, & Cicek, 2002; Ma, Chen, Buss, & Tolin, 1995, 2003; Moon, Jeong, Van, Maroof, & Lee, 2009; Silva, Kiihl, & Almeida, 2004; Tucker, Maroof, Jeong, Buss, & Tolin, 2009). Soybean plants with any of the three loci, namely Rsv1‐h , Rsv1‐k , and Rsv1‐y , showed concurrent resistance to SMV G2 and G3 (Chen et al, 1991).…”

Soybean mosaic virus (SMV) is one of the most widespread and devastating viral diseases worldwide. The genetic architecture of qualitative resistance to SMV in soybean remains unclear. Here, the Rsvg2 locus was identified as underlying soybean resistance to SMV by genome-wide association and linkage analyses. Fine mapping results showed that soybean resistance to SMV strains G2 and G3 was controlled by a single dominant gene, GmST1, on chromosome 13, encoding a sulfotransferase (SOT). A key variation at position 506 in the coding region of GmST1 associated with the structure of the encoded SOT and changed SOT activity levels between RSVG2-S and RSVG2-R alleles. In RSVG2-S allele carrier "Hefeng25", the overexpression of GmST1 carrying the RSVG2-R allele from the SMV-resistant line "Dongnong93-046" conferred resistance to SMV strains G2 and G3. Compared to Hefeng25, the accumulation of SMV was decreased in transgenic plants carrying the RSVG2-R allele. SMV infection differentiated both the accumulation of jasmonates and expression patterns of genes involved in jasmonic acid (JA) signalling, biosynthesis and catabolism in RSVG2-R and RSVG2-S allele carriers. This characterization of GmST1 suggests a new scenario explaining soybean resistance to SMV.
