Abstract:
... The non-expressor of pathogenesis-related genes 1 (NPR1) plays essential roles in the salicylic acid (SA) signal pathway and in systemic acquired resistance (SAR) responses. Although a genome-wide analysis of NPR1 gene family has been conducted in some plant species, little is known about these genes in apple (Malus spp.). In this study, eight NPR1 homologs were identified within the apple genome ...

Abstract:
... Soluble sugars and organic acids have a strong impact on the overall organoleptic quality of fruits. In this study, we report the identification of quantitative trait loci (QTLs) for individual sugars and organic acids in apple. A high density linkage map of apple was constructed using the 1536 EST-derived SNP GoldenGate genotyping platform. The linkage map consists of 601 molecular markers, inclu ...

Abstract:
... The development of molecular markers linked to specific traits is now routine practice, but the gap between genomics and breeding often delays their application. In the frame of the FP7 European project FruitBreedomics, apple pilot studies were designed to exploit the project’s outcomes towards the practical application of marker-assisted breeding (MAB) programs. The aim of this pilot study was to ...

Abstract:
... Rosy apple aphid (Dysaphis plantaginea), is one of the major insect pests of apple, causing serious physical and economic damage to fruit production. A dominant resistance gene Dp-fl was previously mapped at the bottom of linkage group LG8 from the cultivar ‘Florina’, linked to the SSR CH01h10. The development of additional genetic markers mapping closer to Dp-fl was needed to position the gene ac ...

Abstract:
... Accurate prediction of genetic potential and response to selection in breeding requires knowledge of genetic parameters for important selection traits. Data from breeding trials can be used to obtain estimates of these parameters so that predictions are directly relevant to the improvement program. Here, a factor allocation diagram was developed to describe the sampling design used to assess the q ...

A set of 87 apple accessions, located in three Portuguese apple germplasm collections, plus eight reference cultivars, were analyzed using 16 SSRs with the aim of assessing their genetic diversity and structure and evaluating relationships among them. Among the accessions studied, 64 unique genotypes were identified, 51 diploids and 13 putative triploids, revealing 19 groups of synonyms and 4 of h ...

The basic leucine zipper (bZIP) family is one of the largest transcription factor (TF) families in plants, which play crucial roles in plant growth and development. bZIP proteins are involved in multiple biological processes, as well as responses to various biotic/abiotic stresses. Although genome-wide analysis of the bZIP gene family has been conducted in several plant species, only few comprehen ...

Resources for resistance can be found in Malus wild species accession such as Malus ×robusta 5 (Mr5) which carries the FB_MR5 CC-NBS-LRR fire blight resistance gene. To study the occurrence of FB_MR5 in other genetic resources of Malus, a total of 394 wild species accessions of three international ...

Abstract:
... The molecular control of bud dormancy establishment and release is still not well understood, although some genes have already been demonstrated to play important roles in this process. The dormancy-associated MADS-box (DAM) genes were first identified in the peach EVERGROWING locus and are considered the main regulators of bud dormancy control. In this work, the apple (Malus × domestica Borkh.), ...

Abstract:
... Well-feathered apple trees are essential for commercial orchards to optimize yields. However, most cultivars do not form these sylleptic branches readily in commercial nurseries due to high apical dominance. Several treatments exist to promote their formation in the nurseries, one of which is heading. However, not all cultivars are expected to react similarly to these treatments. We studied the br ...

Abstract:
... The red skin color desired by most apple consumers is not easy to achieve in warm climates, as the expression of MYB10, which regulates red pigmentation in apple, is influenced negatively by high temperatures. We describe the development and validation of a genetic marker for red skin coloration that effectively predicts color in a warm summer environment in Spain, as well as more temperate climat ...

Abstract:
... We constructed a high-density genetic linkage map of bronze loquat (Eriobotrya deflexa) by using a three-way cross of loquat (Eriobotrya japonica) × (loquat × bronze loquat) and simple sequence repeat (SSR) and random amplified polymorphic DNA (RAPD) markers. The positions of the SSR loci used in this study were previously identified on reference maps of pears (Pyrus spp.) and apples (Malus spp.). ...
