“…This was confirmed by Yamanaka et al (2005), who reported that the results of mapping could not be directly applied for the mapping of other populations due to the wide diversity of the populations. In addition, the practical interpretation of molecular genetics results is complicated by the fact that the majority of mapping and marker development work is carried out at the diploid level, while in practice breeders use mainly tetraploid materials.…”

Development of a locus-specific marker and localization of the Rysto gene based on linkage to a catalase gene on chromosome XII in the tetraploid potato genome

As a result of many decades of potato breeding in Keszthely, Hungary, numerous varieties resistant to the pathogens attacking potato have been developed using wild Solanum species as resistance sources. In order to simplify the time-consuming breeding process, the present research project involved the development of a SCAR marker correlating with the Ry sto gene, originating from the Solanum stoloniferun species and conferring extreme resistance to the potato Y virus (PVY), using sequence information from a RAPD marker linked to the gene. The usefulness of the marker was tested on 21 varieties resistant or susceptible to PVY and it was found to provide efficient identification of genotypes carrying the Ry sto gene. Based on its linkage to a new chromosome-specific anchor marker (Cat-in2), identified by means of the intron-targeting method not previously used in potato research, the Ry sto gene was localized on chromosome XII.

Conditional QTL underlying resistance to late blight in a diploid potato population

A large number of quantitative trait loci (QTL) for resistance to late blight of potato have been reported with a "conventional" method in which each phenotypic trait reflects the cumulative genetic effects for the duration of the disease process. However, as genes controlling response to disease may have unique contributions with specific temporal features, it is important to consider the phenotype as dynamic. Here, using the net genetic effects evidenced at consecutive time points during disease development, we report the first conditional mapping of QTL underlying late blight resistance in potato under five environments in Peru. Six conditional QTL were mapped, one each on chromosome 2, 7 and 12 and three on chromosome 9. These QTL represent distinct contributions to the phenotypic variation at different stages of disease development. By comparison, when conventional mapping was conducted, only one QTL was detected on chromosome 9. This QTL was the same as one of the conditional QTL. The results imply that conditional QTL reflect genes that function at particular stages during the host-pathogen interaction. The dynamics revealed by conditional QTL mapping could contribute to the understanding of the molecular mechanism of late blight resistance and these QTL could be used to target genes for marker development or manipulation to improve resistance.

“…SSRs are a class of DNA markers based on short tandem repeat sequences (2-6 bp), which are ubiquitous, locus-specific, codominant, highly polymorphic, and well distributed throughout the genome. These characteristics make them ideal markers for applications in genetic mapping and genetic map comparisons (Rosa et al 2003;Kenis and Keulemans 2005;Pelgas et al 2005;Yamanaka et al 2005;Grando et al 2003). Grattapaglia and Sederoff (1994) have postulated that the application of RAPD markers is an efficient first step towards establishing a genomic map for plants where little or nothing is known about the sequence of the genomic DNA.…”

To lay the foundation for molecular breeding efforts, the first genetic linkage map of mulberry (2n=2x=28) was constructed with 50 F1 full-sib progeny using randomly amplified polymorphic DNA (RAPD), inter-simple sequence repeat (ISSR), and simple sequence repeat (SSR) markers and two-way pseudotestcross mapping strategy. We selected 100 RAPD, 42 ISSR, and 9 SSR primers that amplified 517 markers, of which 188 (36.36%) showed a test-cross configuration, corresponding to the heterozygous condition in one parent and null in the other. Two separate female and male maps were constructed using 94 each of female-and male-specific testcross markers, containing 12 female linkage groups and 14 male linkage groups. At a minimum logarithm of the odds (LOD) score threshold of 6.0 and at a maximum map distance of 20 cM, the female map covered a 1,196.6-cM distance, with an average distance of 15.75 cM and maximum map distance of 37.9 cM between two loci; the male-specific map covered a 1,351.7-cM distance, with an average distance of 18.78 cM and a maximum map distance between two loci is of 34.7 cM. The markers distributed randomly in all linkage groups without any clustering. All 12 linkage groups in the female-specific map consisted of 4-10 loci ranging in length from 0 to 140.4 cM, and in the malespecific map, the 13 largest linkage groups (except linkage group 12, which contained three loci) consisted of 4-12 loci, ranging in length from 53.9 to 145.9 cM and accounting for 97.22% of the total map distance. When mapping, progeny pass through their juvenile phase and assume their adult characters, mapping morphological markers and identification of quantitative trait loci for adaptive traits will be the primary target. In that sense, our map provides reference information for future molecular breeding work on Morus and its relatives.
