Abstract
KEY MESSAGE A new resistance locus acting against the potato cyst nematode Globodera pallida was mapped to chromosome VI in the diploid wild potato species Solanum spegazzinii CPC 7195. The potato cyst nematodes (PCN) Globodera pallida and Globodera rostochiensis are economically important potato pests in almost all regions where potato is grown. One important management strategy involves deployment through introgression breeding into modern cultivars of new sources of naturally occurring resistance from wild potato species. We describe a new source of resistance to G. pallida from wild potato germplasm. The diploid species Solanum spegazzinii Bitter accession CPC 7195 shows resistance to G. pallida pathotypes Pa1 and Pa2/3. A cross and first backcross of S. spegazzinii with Solanum tuberosum Group Phureja cultivar Mayan Gold were performed, and the level of resistance to G. pallida Pa2/3 was determined in progeny clones. Bulk-segregant analysis (BSA) using generic mapping enrichment sequencing (GenSeq) and genotyping-by-sequencing were performed to identify single-nucleotide polymorphisms (SNPs) that are genetically linked to the resistance, using S. tuberosum Group Phureja clone DM1-3 516 R44 as a reference genome. These SNPs were converted into allele-specific PCR assays, and the resistance was mapped to an interval of roughly 118 kb on chromosome VI. This newly identified resistance, which we call Gpa VIlspg, can be used in future efforts to produce modern cultivars with enhanced and broad-spectrum resistances to the major pests and pathogens of potato.

Identification of novel associations of candidate genes with resistance to Rhizoctonia solani AG-3PT in Solanum tuberosum stem canker. Int J Biol Macromol 2022; 215:321-333. [PMID: 35718157 DOI: 10.1016/j.ijbiomac.2022.06.105] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2022] [Revised: 06/10/2022] [Accepted: 06/13/2022] [Indexed: 11/05/2022]
Abstract
To develop an understanding mechanism to define responding of potatoes to R. solani, we analyzed the expression of ten novel candidate gene-markers using reverse-transcription-quantitative PCR (RT-qPCR) in resistant 'Savalan' and partially resistant 'Agria' in contrast to susceptible 'Sagita', and partially susceptible 'Pashandi'. In addition, oxidant-enzymatic-activity of catalase and superoxide-dismutase, as well as biomass-growth-parameters; shoot and root length, fresh and dry weight, and root volume were considered as complementary factors to the involving mechanism accordingly. Gene-markers up-regulated maximum up to 3.5-fold with the highest correlation, r = 0.939** following R. solani-inoculation, predominantly in resistant genotypes. Surprisingly, WRKY8-gene, basically resistant to late-blight-Phytophtora infestans was also up-regulated to 2.3-fold in resistant 'Savalan' followed by 'Agria'. Similar results with 3.1-fold were obtained on Osmotin-gene resistant to early-blight-Alternaria alternata. Enzymatic-activity of catalase with 1.6-fold and superoxide-dismutase, 6.8-fold also showed the highest level of activity in resistant genotypes, and had a high significant correlation, r = 773** and r = 0.881** with expression levels of related gene-markers respectively. Similarly, there were significant differences in biomass-growth-parameters, but with reductions in partially susceptible 'Sagita' and susceptible 'Pashandi'. Conclusively, S. tuberosum-R. solani interaction revealed that certain gene-markers can cover resistance to more than one disease simultaneously.

Physical Localization of the Root-Knot Nematode ( Meloidogyne incognita) Resistance Locus Me7 in Pepper ( Capsicum annuum). FRONTIERS IN PLANT SCIENCE 2019; 10:886. [PMID: 31354762 PMCID: PMC6629957 DOI: 10.3389/fpls.2019.00886] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/02/2019] [Accepted: 06/21/2019] [Indexed: 05/09/2023]
Abstract
The root-knot nematode (RKN) Meloidogyne incognita severely reduces yields of pepper (Capsicum annuum) worldwide. A single dominant locus, Me7, conferring RKN resistance was previously mapped on the long arm of pepper chromosome P9. In the present study, the Me7 locus was fine mapped using an F2 population of 714 plants derived from a cross between the RKN-susceptible parent C. annuum ECW30R and the RKN-resistant parent C. annuum CM334. CM334 exhibits suppressed RKN juvenile movement, suppressed feeding site enlargement and significant reduction in gall formation compared with ECW30R. RKN resistance screening in the F2 population identified 558 resistant and 156 susceptible plants, which fit a 3:1 ratio confirming that this RKN resistance was controlled by a single dominant gene. Using the C. annuum CM334 reference genome and BAC library sequencing, fine mapping of Me7 markers was performed. The Me7 locus was delimited between two markers G21U3 and G43U3 covering a physical interval of approximately 394.7 kb on the CM334 chromosome P9. Nine markers co-segregated with the Me7 gene. A cluster of 25 putative nucleotide-binding site and leucine-rich repeat (NBS-LRR)-type disease resistance genes were predicted in the delimited Me7 region. We propose that RKN resistance in CM334 is mediated by one or more of these NBS-LRR class R genes. The Me7-linked markers identified here will facilitate marker-assisted selection (MAS) for RKN resistance in pepper breeding programs, as well as functional analysis of Me7 candidate genes in C. annuum.

Abstract
Genomic analyses have shown that most genes in eukaryotic lineages belong to families. Gene families vary in terms of number of members, nucleotide similarity, gene integrity, expression, and function. Often, the members of gene families are arranged in clusters, which contribute to maintaining similarity among gene copies and also to generate duplicates through replication errors. Gene families offer us an opportunity to examine the forces involved in the evolution of the genomes and to study recombination events and genomic rearrangements. In this work, we focused on the evolution of two plant resistance gene families, Sw5 and Mi-1, and analyzed the completely sequenced nuclear genomes of potato and tomato. We first noticed that the potato genome carries larger resistance gene families than tomato, but all gene copies are pseudogenes. Second, phylogenetic analyses indicated that Sw5 and Mi-1 gene families had dissimilar evolutionary histories. In contrast to Sw5, Mi-1 homologues suffered repeated gene conversion events among the gene copies, particularly in the tomato genome.
