In this research, the objective was to investigate whether quantitative trait locus (QTL) mapping could identify genomic regions that affect nut and kernel traits in the almond varieties Nonpareil and Lauranne and to investigate whether these regions have effects in two other almond populations (Nonpareil × Constantí and Nonpareil × Tarraco). Linkage mapping and QTL analysis were carried out using single-nucleotide polymorphisms (SNPs) that had previously been discovered using a set of 180 Nonpareil × Lauranne F₁ progeny. With the Nonpareil × Lauranne population, QTLs were detected in ten regions on the Nonpareil map and 16 regions on the Lauranne map. Each Nonpareil QTL region and most Lauranne QTL regions were also detected using the Constantí and/or Tarraco populations. Most QTLs had small effects, indicating that the traits investigated here may be more suitable for genomic selection than for marker-assisted selection. With anchoring of QTL regions to genome sequence assemblies for Nonpareil and Lauranne, some candidate genes were identified that could be evaluated in future research.</p>","PeriodicalId":23335,"journal":{"name":"Tree Genetics & Genomes","volume":"1 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138534039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phylogenetic analysis based on complete chloroplast genome sequence showed that <i>Q. suber</i> is closely related to <i>Quercus variabilis</i>, two cork-producing species with commercial use.

Henry, and Populus trichocarpa Torr. &amp; Gray, 3 and 6 years after planting. The use of spatial analysis proved to be the best method for quantitative growth data. The proportion of the among-family variance to the total (phenotypic) variance as well as the high heritabilities of growth and susceptibility to frost and Spaherulina musiva showed a high potential for selection for these traits while the quality traits were under low genetic control. Some families showed gains for several traits, suggesting the possibility of developing a selection index to obtain superior families that show gain for not only growth but quality and adaptive traits as well. Type B correlations were high, suggesting that families responded in the same way regardless of the site. High type A correlation between growth traits at 3 and 6 years showed early selection potential, although these relationships should be confirmed with future measurements to evaluate this effect at maturity. These results can be integrated into the strategy for improving hybrid poplar parental populations and, in the longer term, will make it possible to optimize the selection of individuals with traits of interest for the operational deployment of hybrid poplar clones.","PeriodicalId":23335,"journal":{"name":"Tree Genetics & Genomes","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135667793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quercus magnoliifolia and Q. resinosa are two endemic oak species distributed across the Mexican highlands. These species diverged ecological and morphologically; however, no nuclear genetic differentiation is evident. In this study, we determined the mechanisms that shape patterns of genetic variation and establish the role of migration and hybridization in the evolutionary history of these two oak species. To do this, Bayesian approaches were used for inference on migration rates and directionality and timing of divergence between species using chloroplast microsatellites. We then integrated species distribution models to infer the geographic distribution of Q. magnoliifolia and Q. resinosa during Last Interglacial, Last Glacial Maximum, and Mid-Holocene time frames. We failed in distinguishing a unique genetic composition for each species. Chloroplast differentiation was more congruent with geography than the taxonomic status of each species. Our study revealed that after the divergence ( c . 10 Mya) of these two oak species, high rates of introgression took place at the end of the Pleistocene. Furthermore, past distribution models predicted that Q. magnoliifolia and Q. resinosa have likely been in sympatry presumable since Last Glacial Maximum and Q. resinosa probably expanded geographically towards its current distribution around Mid-Holocene. This expansion was supported by testing migration models, suggesting recent establishment of Q. resinosa to the north of Trans-Mexican Volcanic Belt. We hypothesized that after Q. magnoliifolia and Q. resinosa diverged, colonization events followed by hybridization between oaks and long-distance seed dispersal occurred, explaining the present-day patterns of distribution of chloroplast diversity. We propose that divergence of species remains mainly on loci under natural selection, providing evidence on the “porous” nature of species boundaries among oaks.","PeriodicalId":23335,"journal":{"name":"Tree Genetics & Genomes","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135834703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
