Open AccessDiversity in bread and durum wheat stigma morphology and linkage of increased stigma length to dwarfing gene Rht14
The dwarfing allele Rht14 of durum wheat associates with greater stigma length, an important trait for hybrid breeding, whilst major dwarfing alleles Rht-B1b and Rht-D1b showed little to no effect.

Open AccessNested association map**-based GWAS for grain yield and related traits in wheat grown under diverse Australian environments
Utilising a nested association map** (NAM) population-based GWAS, 98 stable marker-trait associations with 127 alleles unique to the exotic parents were detected for grain yield and related traits in wheat.

The genetics of vigour-related traits in chickpea (Cicer arietinum L.): insights from genomic data
QTL controlling vigour and related traits were identified in a chickpea RIL population and validated in diverse sets of germplasm. Robust KASP markers were developed for marker-assisted selection.

Open AccessQTL analysis and fine map** of a QTL for yield-related traits in wheat grown in dry and hot environments
Genetic control of grain yield and phenology was examined in the Excalibur/Kukri doubled haploid map** population grown in 32 field experiments across the climatic zones of southern Australia, India and nort...

Effects of Rht-B1 and Ppd-D1 loci on pollinator traits in wheat
Elite wheat pollinators are critical for successful hybrid breeding. We identified Rht-B1 and Ppd-D1 loci affecting multiple pollinator traits and therefore represent major targets for improving hybrid seed produ...

Open AccessDAWN: a resource for yielding insights into the diversity among wheat genomes
Democratising the growing body of whole genome sequencing data available for Triticum aestivum (bread wheat) has been impeded by the lack of a genome reference and the large computational requirements for analysi...

Open AccessOptical and physical map** with local finishing enables megabase-scale resolution of agronomically important regions in the wheat genome
Numerous scaffold-level sequences for wheat are now being released and, in this context, we report on a strategy for improving the overall assembly to a level comparable to that of the human genome.

Open AccessAllelic variants of OsSUB1A cause differential expression of transcription factor genes in response to submergence in rice
Flooding during seasonal monsoons affects millions of hectares of rice-cultivated areas across Asia. Submerged rice plants die within a week due to lack of oxygen, light and excessive elongation growth to esca...

Open AccessTranscriptome-scale homoeolog-specific transcript assemblies of bread wheat
Bread wheat is one of the world’s most important food crops and considerable efforts have been made to develop genomic resources for this species. This includes an on-going project by the International Wheat G...

Protocol
Fluorescence-Activated Cell Sorting for Analysis of Cell Type-Specific Responses to Salinity Stress in Arabidopsis and Rice
Fluorescence-activated cell sorting (FACS) provides a rapid means of isolating large numbers of fluorescently tagged cells from a heterogeneous mixture of cells. Collections of transgenic plants with cell type...

Open AccessDiscovery of barley miRNAs through deep sequencing of short reads
MicroRNAs are important components of the regulatory network of biological systems and thousands have been discovered in both animals and plants. Systematic investigations performed in species with sequenced g...

Varietal and chromosome 2H locus-specific frost tolerance in reproductive tissues of barley (Hordeum vulgare L.) detected using a frost simulation chamber
Exposure of flowering cereal crops to frost can cause sterility and grain damage, resulting in significant losses. However, efforts to breed for improved low temperature tolerance in reproductive tissues (LTR ...

Article
Open AccessComparative transcriptomics in the Triticeae
Barley and particularly wheat are two grass species of immense agricultural importance. In spite of polyploidization events within the latter, studies have shown that genotypically and phenotypically these spe...

Flt-2L, a locus in barley controlling flowering time, spike density, and plant height
Flowering time represents an important adaptive trait for temperate cereal crops and may also impact on frost damage in cereal reproductive tissues by enabling escape or by influencing accumulation of genuine ...

Genes and traits associated with chromosome 2H and 5H regions controlling sensitivity of reproductive tissues to frost in barley
Frost at flowering can cause significant damage to cereal crops. QTL for low temperature tolerance in reproductive tissues (LTR tolerance) were previously described on barley 2HL and 5HL chromosome arms. With ...

Structure–function analysis of the barley genome: the gene-rich region of chromosome 2HL
A major gene-rich region on the end of the long arm of Triticeae group 2 chromosomes exhibits high recombination frequencies, making it an attractive region for positional cloning. Traits known to be controlle...

Open AccessConserved upstream open reading frames in higher plants
Upstream open reading frames (uORFs) can down-regulate the translation of the main open reading frame (mORF) through two broad mechanisms: ribosomal stalling and reducing reinitiation efficiency. In distantly ...

Identification of transposons, retroelements, and a gene family predominantly expressed in floral tissues in chromosome 3DS of the hexaploid wheat progenitor Aegilops tauschii
A multigene family expressed during early floral development was identified on the short arm of wheat chromosome 3D in the region of the Ph2 locus, a locus controlling homoeologous chromosome pairing in allohexap...

Open AccessMicroarray expression analysis of meiosis and microsporogenesis in hexaploid bread wheat
Our understanding of the mechanisms that govern the cellular process of meiosis is limited in higher plants with polyploid genomes. Bread wheat is an allohexaploid that behaves as a diploid during meiosis. Chr...
