Mycosphaerella leaf disease (MLD) is one of the most prevalent foliar diseases of E. globulus plantations around the world. Since resistance management strategies have not been effective in commercial plantations, breeding to develop more resistant genotypes is the most promising strategy. Available genomic information can be used to detect genomic regions associated with resistance to MLD, which could significantly speed up the process of genetic improvement. In this study, we investigated the genetic basis of MLD resistance in a breeding population of E. globulus which was genotyped with the EUChip60K SNP array. Resistance to MLD was evaluated for resistance of the juvenile foliage, as defoliation and leaf spot severity, and for precocity of change to resistant adult foliage. Genome-wide association studies (GWAS) were carried out applying four Single-SNP models, a Genomic Best Linear Unbiased Prediction (GBLUP-GWAS) approach, and a Single-step genome-wide association study (ssGWAS). The Single-SNP and GBLUP-GWAS models detected 13 and 16 SNP-trait associations in chromosomes 2, 3 y 11; whereas the ssGWAS detected 66 SNP-trait associations in the same chromosomes, and additional significant SNP-trait associations in chromosomes 5 to 9 for the precocity of phase change (proportion of adult foliage). For this trait, the two main regions in chromosomes 3 and 11 were identified for the three approaches. The SNPs identified in these regions were positioned near the key miRNA genes, miR156.5 and miR157.4, which have a main role in the regulation of the timing of vegetative change, and also in the response to environmental stresses in plants. Our results outlined that ssGWAS was more powerful in detecting regions that affect resistance than conventional GWAS approaches. Additionally, suggest a polygenic genetic architecture for the heteroblastic transition in E. globulus and identified useful SNP markers for the development of marker-assisted selection strategies for resistance.

Abstract:
Pear is a fruit of great importance for human nutrition due to the organoleptic characteristics and nutritional composition. Its cultivation in Uruguay generally uses rootstocks for adaptation to the soil, productiveness and precociousness, but rootstock selection may also influence fruit quality, with the ability to change its chemical composition. The objective of this work was to evaluate the influence of rootstocks on some physicochemical and nutritional compounds of 'Williams' pear, grafted on six rootstocks (EMC, BA29, OH×F333, OH×F40, OH×F69 and Adams) in Uruguayan production conditions. The experimental design was a randomized complete block design with four replicates located in an orchard at INIA-Las Brujas Experimental Station. At harvest, 20 fruits were sampled per replicate, conditioned in a cold chamber and then at room temperature until consumer maturation. Soluble solids content, titratable acidity, color and texture were evaluated and then fruit peel and pulp were separated for determination of ascorbic acid and minerals contents. As a result, in relation to the soluble solids, titratable acidity, color and texture, no differences were found between the rootstocks. For ascorbic acid content, no significant differences between rootstocks were found, but the concentration was higher in the fruit peel than pulp. The highest phosphorus content was found in the pulp, but calcium and magnesium contents were higher in the peel. The OH×F40 and OH×F69 rootstocks provided higher phosphorus and zinc contents and the boron content was higher in fruits of plants grafted on OH×F40 rootstock. As a conclusion, rootstocks influenced the nutritional content of 'Williams' pear fruits under Uruguayan cultivation conditions, which makes it possible to select a more convenient rootstock in terms of production and to contribute with a greater amount of nutrient in fruits.
