We present a draft assembly of the genome European pear (Pyrus communis) 'Bartlett'. Our was developed employing second generation sequencing technology (Roche 454), from single-end, 2 kb, and 7 kb insert paired-end reads using Newbler (version 2.7). It contains 142,083 scaffolds greater than 499 bases (maximum scaffold length 1.2 Mb) covers total 577.3 Mb, representing most expected 600 Mb Pyrus genome. A 829,823 putative single nucleotide polymorphisms (SNPs) were detected re-sequencing...
Most published genome sequences are drafts, and most dominated by computational gene prediction. Draft genomes typically incorporate considerable sequence data that not assigned to chromosomes, predicted genes without quality confidence measures. The current Actinidia chinensis (kiwifruit) 'Hongyang' draft has 164 Mb of unassigned pseudo-chromosomes, omissions have been identified in the models.A second an A. (genotype Red5) was fully sequenced. This new resulted a 554.0 assembly with all...
We have used new generation sequencing (NGS) technologies to identify single nucleotide polymorphism (SNP) markers from three European pear (Pyrus communis L.) cultivars and subsequently developed a subset of 1096 SNPs into high throughput by combining them with the set 7692 apple on IRSC Infinium® II 8K array. then evaluated this 9K SNP array for large-scale genotyping in across several species, using both SNPs. The segregating populations employed validation included population ('Old...
Both a source of diversity and the development genomic tools, such as reference genomes molecular markers, are equally important to enable faster progress in plant breeding. Pear (Pyrus spp.) lags far behind other fruit nut crops terms employment available genetic resources for new cultivar development. To address this gap, we designed high-density, high-efficiency robust single nucleotide polymorphism (SNP) array pear, with main objectives conducting genome-wide association studies. By...
The vigour and precocity of trees highly influences their efficiency in commercial production. In apple, dwarfing rootstocks allow high-density plantings while precocious flowering enables earlier fruit Currently, there is a lack pear (Pyrus communis L.) that are equivalent to the high yielding apple rootstock 'M9'. For efficient breeding new Pyrus it crucial understand genetic determinants control precocity. this study we used quantitative trait loci (QTLs) analysis identify associated with...
Terpene volatiles are found in many important fruit crops, but their relationship to flavor is poorly understood. Here, we demonstrate using sensory descriptive and discriminant analysis that 1,8-cineole contributes a key floral/eucalyptus note the aroma of ripe 'Hort16A' kiwifruit (Actinidia chinensis). Two quantitative trait loci (QTLs) for production were identified on linkage groups 27 29a segregating A. chinensis population, with QTL LG29a colocating complex cluster putative terpene...
Genetic maps are essential tools for pear genetics and genomics research. In this study, we first constructed an integrated simple sequence repeat (SSR) single nucleotide polymorphism (SNP)-based consensus genetic map based on common SSR markers between nine published maps. A total of 5,085 markers, including 1,232 SSRs 3,853 SNPs, were localized a spanning 3,266.0 cM in total, with average marker interval 0.64 cM, which represents the highest density to date. Using three sets high-density...
Highbush blueberry (Vaccinium corymbosum, 2n = 4x 48) is the most cultivated type of blueberry, both in New Zealand and overseas. Its perceived nutritional value conferred by phytonutrients, particularly anthocyanins. Identifying genetic mechanisms that control biosynthesis these metabolites would enable faster development cultivars with improved fruit qualities. Here, we used recently released tools for mapping autotetraploids to build a high-density linkage map highbush detect quantitative...
Abstract Commercially grown kiwifruit (genus Actinidia) are generally of two sub-species which have a base haploid genome 29 chromosomes. The yellow-fleshed Actinidia chinensis var. chinensis, is either diploid (2n = 2x 58) or tetraploid 4x 116) and the green-fleshed cultivar A. deliciosa “Hayward,” hexaploid 6x 174). Advances in breeding green could be greatly sped up by use molecular resources for more efficient faster selection, example using marker-assisted selection (MAS). key genetic...
The availability of Pyrus rootstocks that reduce tree size, enhance precocity and are also easy to propagate is limited. In general, European pears considered a difficult-to-root species, this trait one the obstacles developing successful clonal for pear fruit production. Identifying parent which would be benefit in rootstock development programme. Using dormant hardwood cuttings, we compared propagation success rates 81 different cultivars, with 303 seedling population from communis ‘Old...
The limited availability of a Pyrus-derived dwarfing rootstock, equivalent to apple’s ‘Malling 9’, limits the intensification modern pear orchards. As part search for Pyrus this paper examines diversity key rootstock traits in population 420 P. communis seedlings from cross between ‘Old Home’ and ‘Louise Bonne de Jersey’. were used as rootstocks, budded with scion ‘Doyenne du Comice’, rootstock-induced changes development phenotyped relating tree architecture flowering. rootstocks induced...
