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 AccessGenome-wide identification and characterization of the GDP-L-galactose phosphorylase gene family in bread wheat
Ascorbate is a powerful antioxidant in plants and an essential micronutrient for humans. The GDP-L-galactose phosphorylase (GGP) gene encodes the rate-limiting enzyme of the L-galactose pathway—the dominant ascor...

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 AccessOpposite fates of the purine metabolite allantoin under water and nitrogen limitations in bread wheat
Degradation of nitrogen-rich purines is tightly and oppositely regulated under drought and low nitrogen supply in bread wheat. Allantoin is a key target metabolite for improving nitrogen homeostasis under stress.

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 AccessWheat TaMs1 is a glycosylphosphatidylinositol-anchored lipid transfer protein necessary for pollen development
In flowering plants, lipid biosynthesis and transport within anthers is essential for male reproductive success. TaMs1, a dominant wheat fertility gene located on chromosome 4BS, has been previously fine mapped a...

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...

Nitrogen assimilation system in maize is regulated by developmental and tissue-specific mechanisms
We found metabolites, enzyme activities and enzyme transcript abundances vary significantly across the maize lifecycle, but weak correlation exists between the three groups. We identified putative genes regula...

Molecular interactions of the γ-clade homeodomain-leucine zipper class I transcription factors during the wheat response to water deficit
The γ-clade of class I homeodomain-leucine zipper (HD-Zip I) transcription factors (TFs) constitute members which play a role in adapting plant growth to conditions of water deficit. Given the importance of wh...

Open AccessShoot chloride exclusion and salt tolerance in grapevine is associated with differential ion transporter expression in roots
Salt tolerance in grapevine is associated with chloride (Cl−) exclusion from shoots; the rate-limiting step being the passage of Cl− between the root symplast and xylem apoplast. Despite an understanding of the p...

Open AccessSequencing error correction without a reference genome
Next (second) generation sequencing is an increasingly important tool for many areas of molecular biology, however, care must be taken when interpreting its output. Even a low error rate can cause a large numb...
