*Chilling requirement, together with heat determines the bloom date, which has an impact on climatic distribution of genotypes tree species. The molecular basis floral bud chilling requirement is poorly understood, despite its importance to adaptation and production fruit trees. In addition, genetic nature interrelationships among date remain unclear. *A peach (Prunus persica) F(2) population 378 developed from two contrasting requirements was used for linkage map construction quantitative...
Low-cost, high throughput genotyping methods are crucial to marker discovery and marker-assisted breeding efforts, but have not been available for many 'specialty crops' such as fruit nut trees. Here we apply the Genotyping-By-Sequencing (GBS) method developed cereals of single nucleotide polymorphisms (SNPs) in a peach F2 mapping population. Peach is genetic genomic model within Rosaceae will provide template use this with other members family. Our population 57 genotypes segregates bloom...
Evergrowing (EVG) peach is one of only two described mutants affecting winter dormancy in woody perennial species. EVG does not set terminal buds, cease new leaf growth, nor enter into a dormant resting phase response to conditions. The mutation segregates F2 progeny as single recessive nuclear gene. A local molecular genetic linkage map around was previously developed using amplified fragment length polymorphism (AFLP) and simple sequence repeat (SSR) markers, bacterial artificial...
Commercial production of apricot is severely affected by sensitivity to climatic conditions, an adaptive feature essential for cycling between vegetative or floral growth and dormancy. Yield losses are due late winter early spring frosts inhibited caused unfulfilled chilling requirement (CR). Two cultivars, Perfection A.1740, were selected high low CR, respectively, develop a mapping population F 1 individuals using two-way pseudo-testcross strategy. High-density male female maps constructed...
Over a century after two introduced pathogens decimated American chestnut populations, breeding programs continue to incorporate resistance from Chinese recover self-sustaining populations. Due complex genetics of blight resistance, it is challenging obtain trees with sufficient and competitive growth. We developed high quality reference genomes for leveraged large disease phenotype genotype datasets develop accurate genomic selection. Inoculation simulation results indicate that may be...
Summary White oak ( Quercus alba ) is an abundant forest tree species across eastern North America that ecologically, culturally, and economically important. We report the first haplotype‐resolved chromosome‐scale genome assembly of Q. conduct comparative analyses structure gene content against other published Fagaceae genomes. investigate genetic diversity this widespread phylogenetic relationships among oaks using whole data. Despite strongly conserved chromosome synteny size , certain...
Abstract Resistance to fusiform rust disease in loblolly pine (Pinus taeda) is a classic gene-for-gene system. Early resistance gene mapping the P. taeda family 10-5 identified RAPD markers for major gene, Fr1. More recently, single nucleotide polymorphism (SNP) associated with were mapped full-length model genome encoding nucleotide-binding site leucine-rich repeat (NLR) protein. NLR genes are one of most abundant families plant genomes and involved effector-triggered immunity. Inter-...
Summary White oak ( Quercus alba ) is an abundant forest tree species across eastern North America that ecologically, culturally, and economically important. We report the first haplotype-resolved chromosome-scale genome assembly of Q. conduct comparative analyses structure gene content against other published Fagaceae genomes. In addition, we probe genetic diversity this widespread investigate its phylogenetic relationships with oaks using whole-genome data. Our comprises two haplotypes...
Chestnut blight (caused by Cryphonectria parasitica ), together with Phytophthora root rot cinnamomi has nearly extirpated American chestnut ( Castanea dentata ) from its native range. In contrast to the susceptibility of chestnut, many Chinese C. mollissima genotypes are resistant blight. this research, we performed a series genome-wide association studies for resistance originating three unrelated trees (Mahogany, Nanking and M16) Quantitative Trait Locus (QTL) study on Mahogany-derived...
Abstract Forest tree species are increasingly subject to severe mortalities from exotic pests, diseases, and invasive organisms, accelerated by climate change. health issues threatening multiple ecosystem sustainability globally. While sources of resistance may be available in related species, or among surviving trees, introgression genes into threatened reasonable time frames requires genome-wide breeding tools. Asian chestnut ( Castanea spp.) being employed as donors disease restore native...
Abstract Long noncoding RNAs (lncRNAs) have been shown to act as important cell biological regulators including fate decisions but are often ignored in human genetics. Combining differential lncRNA expression during neuronal lineage induction with copy number variation morbidity maps of a cohort children autism spectrum disorder/intellectual disability versus healthy controls revealed focal genomic mutations affecting several candidate loci. Here we find that t(5:12) chromosomal...
