Mar 23 2020Two of these qShB1–1 and qShB8 had very large effects on the phenotype with the weedy allele conferring an increased resistance at both loci (Table 2) However both of these QTL co-localized with known PH and HD genes sd1 and DTH8 respectively (Sasaki et al 2002 Wei et al 2010 ) and both disappeared when the analysis was performed

Genes sbm-1 sbm-3 and sbm-4 conferring resistance to PSbMV pathotypes PI L-l and P4 respectively are located on chromosome 6 while sbm-2 also conferring resistance to pathotype L-l is located on chromosome 2 [5] Although this organisation is suggestive of local gene conversion and translocation between chromosomes 2 and 6 other

Cloning and characterization of XiR1 a locus responsible

Plant materials and screening for resistance to X index Three mapping populations with a total of 1 375 F 1 genotypes were used to construct a high-resolution genetic map of the XiR1 region The first population 9621 was derived from a cross of D8909-15 F8909-17 in which the XiR1 locus was initially identified (Xu et al 2008) The 9621 population was expanded to 943 F 1 individuals for

The first locus conferring resistance to S endobioticum pathotype 1 (Sen1) was identified on the distal end of the long arm of potato chromosome XI based on restric-tion fragment length polymorphism (RFLP) linkage map-ping in a diploid F1 family [6] Sen1 is part of a 'hot spot' for qualitative and quantitative resistance against

Plant NLRs with Integrated Domains: Unity Makes Strength

In 2001 Deslandes and colleagues cloned a resistance gene encoding RRS1-R (RESISTANCE TO RALSTONIA SOLANACEARUM1) conferring broad-spectrum resistance to the soil-borne bacterium R solanacearum the causal agent of bacterial wilt (Deslandes et al 1998 2002) RRS1-R contains at its C terminus a WRKY DNA-binding domain

Functional Codominant Marker for Selecting the Fw Gene

Fusarium oxysporum f sp pisi (Fop ) is a major soil‐borne pathogen and the causal agent of Fusarium wilt of pea (Pisum sativum L ) resulting in significant yield losses Resistant cultivars have become the most effective method for controlling this fungal disease The gene controlling resistance to F oxysporum race 1 in pea Fw is located on linkage group (LG) III and widely used in

In tomato the I locus introgressed from Lycopersicon pimpinellifolium confers resistance to F o lycopersici race 1 and is located on the short arm of chromo- some 11 between RFLP markers TG523 and CP58 (Y Eshed and N Ori unpublished data) The 13 locus from chromosome 7 of L pennellii confers resistance to races 1 2 and 3 of F o

Dissection of two soybean QTL conferring partial

The QTL 18–2 19–1 and 19–2 which confer resistance to multiple P sojae isolates were first mapped in a Conrad Sloan F 4:6 population using two different phenotypic methods [10 11] In this study all three QTL were confirmed in the larger F 6:8 generation flanked by similar markers as in the F 4:6 population The QTL 18–2 (Gm18: 59016134 to 62263273) co-localized with the

Additional minor QTLs contributing to the resistance were identified at early DAI (10 and 13) on chromosomes 8 11 and 21 Positive alleles of these minor QTLs were contributed by either Pima S-7 or Acala NemX Genetic linkage analysis based on this progeny suggests that the major resistance locus may be located on chromosome 17
