Wheat and Barley Genetics and Pathology

A phylogeographical study reveals the complex history of wheat genetic diversity through time and space.

The paper shows that flowering time genes in barley affect yield under abiotic stress, with environmental cues modulating their effects, and suggests using wild barley genes to improve yield in crops.

The paper analyzes recombination patterns in hexaploid wheat, identifies genes controlling recombination and gene conversion, and highlights a novel RecQ helicase gene involved in gene conversion.

The paper analyzes genetic control and maps QTLs for wheat grain quality traits in a recombinant inbred population across three environments, identifying 38 putative QTLs explaining 7.9% to 16.8% phenotypic variation.

This study identifies QTL for 16 end-use quality traits in wheat using a RIL population and phenotyping across nine environments, finding stable A-QTL and DE-QTL that explain significant phenotypic variation.

This paper clones four stem rust resistance genes in wild diploid wheat using association genetics and R gene enrichment sequencing within six months.

The paper presents and validates two capture probe sets for wheat to enable efficient and cost-effective re-sequencing of genes and promoters.

The paper uses next generation sequencing to identify and remove duplicated germplasm accessions in genebanks, revealing over 50% duplication in Aegilops tauschii collections.

The paper develops a subfunctionalization epistasis model to assess homeologous gene interactions in allopolyploid wheat and evaluates their contribution to genetic variation.

The paper introduces a low-resolution epistasis mapping method to detect chromosome arm interactions in allohexaploid wheat, finding significant epistatic interactions for 2% of tested pairs.

The paper presents a statistical framework to predict subgenome additive and interaction effects in allohexaploid wheat, showing reliable variance estimation and comparable predictive ability to existing methods.

The paper evaluates the yield performance of durum wheat lines with introgressed Thinopyrum ponticum 7AgL chromosome segments across multiple environments, finding significant increases in yield components despite trade-offs in grain weight.

This study uses gene editing and mutagenesis to show that TaGW2 homoeologues contribute additively to grain size and weight in wheat, with inter-cultivar differences in their effects.

The paper introduces a portal linking the bread wheat reference genome to genetic and phenomic data for wheat improvement.

The paper compares the genome sequences of two wheat cultivars to identify structural variations and their evolutionary mechanisms.

The paper assesses and improves wheat genome assemblies using Fosill jumping libraries, finding that whole genome shotgun assemblies are more accurate than BAC-based ones.

The paper introduces a modified sequence capture method that enables simultaneous analysis of genotype and methylation from the same genomic DNA sample in wheat.

The paper identifies a mutation in the Q gene that leads to increased spike density and improved processing quality in wheat by overexpressing Qc1.

A GWAS identifies a barley locus HsDry2.2 with flowering-independent yield benefits under drought, showing wild alleles improve grain yield and morphology.

The paper develops and characterizes wheat-Aegilops peregrina introgression lines with resistance to leaf rust and stripe rust, identifying lines with varying resistance profiles.

The paper presents the first near-complete assembly of the hexaploid bread wheat genome using a combination of short and long-read sequencing technologies.
