Dissecting nematode resistance regions in soybean revealed pleiotropic effect of soybean cyst and reniform nematode resistance genes

چکیده
Reniform nematode (RN, Rotylenchulus reniformis Linford & Oliveira) has emerged as one of the most important plant parasitic nematodes soybean [Glycine max (L.) Merr.]. Planting resistant varieties is effective strategy for management. The objective this study was to identify quantitative trait loci (QTL) RN resistance in an exotic line, PI 438489B, using two linkage maps constructed from Universal Soybean Linkage Panel (USLP 1.0) and next-generation whole-genome resequencing (WGRS) technology. Two QTL controlling were identified—the cyst (SCN, Heterodera glycines) gene GmSNAP18 at rhg1 locus its paralog GmSNAP11. Strong association between phenotype haplotypes GmSNAP11 observed. results indicated that possibly could have epistatic effect on GmSNAP18, or vice versa, with presence a significant correlation rhg1-a vs. rhg1-b GmSNAP18. Most importantly, our preliminary data suggested proteins physically interact planta, suggesting they belong same pathway resistance. Unlike no indication copy number variation found. Moreover, gene-based single nucleotide polymorphism (SNP) markers developed rapid detection SCN these loci. Our analysis substantiates synergic interaction genes confirms their roles well These contribute better understanding evolution subfunctionalization conferring multiple species provide framework further investigations.

A set of 585 informative single-nucleotide polymorphism (SNP) loci was used to genotype both a panel of diverse accessions and a set of recombinant inbred lines (RILs) bred from the cross Zhongpin03-5373 (ZP; resistant to SCN) × Zhonghuang13 (ZH; susceptible). The SNP loci are mostly sited within genic sequence in regions of the soybean [ (L.) Merr.] genome thought to harbor genes determining r...

The soybean cyst nematode (SCN) Heterodera glycines is a major threat to soybean production, made more challenging by the current limitations of natural resistance for managing this pathogen. The use of resistant host cultivars is effective, but, over time, results in the generation of virulent nematode populations able to robustly parasitize the resistant host. In order to understand how virul...

Soybean cyst nematode (SCN) (Heterodera glycines Ichinohe) is the most important pest of soybean [Glycine max (L.) Merr.] in the world. A total of 17 quantitative trait locus (QTL) mapping papers and 62 marker–QTL associations have been reported for resistance to soybean cyst nematode in soybean. Conflicting results often occurred. The objectives of this study were to: (i) evaluate evidence for...
متن کاملTransgenic soybean overexpressing GmSAMT1 exhibits resistance to multiple‐HG types of soybean cyst nematode Heterodera glycines
Soybean (Glycine max (L.) Merr.) salicylic acid methyl transferase (GmSAMT1) catalyses the conversion of salicylic acid to methyl salicylate. Prior results showed that when GmSAMT1 was overexpressed in transgenic soybean hairy roots, resistance is conferred against soybean cyst nematode (SCN), Heterodera glycines Ichinohe. In this study, we produced transgenic soybean overexpressing GmSAMT1 and...
