Open AccessA novel highly differentially expressed gene in wheat endosperm associated with bread quality
Analysis of gene expression in develo** wheat seeds was used to identify a gene, wheat bread making (wbm), with highly differential expression (~1000 fold) in the starchy endosperm of genotypes varying in bread...

Characterisation of alleles of the sucrose phosphate synthase gene family in sugarcane and their association with sugar-related traits
Sucrose phosphate synthase (SPS) is a key enzyme in the production of sucrose. Five SPS gene families have been identified in monocotyledonous plants including sugarcane. Using SPS family-specific primers to f...

Wild Oryza Grain Physico-Chemical Properties
Of the 22 species within the Oryza genus, only two, O. sativa and O. glaberrima, have been domesticated. Although food security is supported by accessing wild Oryza resources for new genes and alleles which enhan...

SSR analysis of introgression of drought tolerance from the genome of Hordeum spontaneum into cultivated barley (Hordeum vulgare ssp vulgare)
Wild barley (Hordeum vulgare ssp. spontaneum) and landraces are important sources of resistance to biotic and abiotic stresses since they possess wide genetic diversity that may be missing in current elite variet...

Open AccessThe Endosperm Morphology of Rice and its Wild Relatives as Observed by Scanning Electron Microscopy
While cultivated rice, Oryza sativa, is arguably the world’s most important cereal crop, there is little comparative morphological information available for the grain of rice wild relatives. In this study, the en...

Erianthus
The genus Erianthus is related to Saccharum (sugarcane) and Miscanthus (a potential energy crop), and is part of the Saccharum complex. Taxonomy of Erianthus is confusing: some taxonomists regard Erianthus as bei...

Saccharum
The genus Saccharum contains only a few species, may be as few as two, as the status of four others, potentially within Saccharum officinarum, is not resolved. The members of the genus are polyploid with very lar...

Sorghum resolved as a distinct genus based on combined ITS1, ndhF and Adh1 analyses
Recent studies on Sorghum have attempted to determine the genetic relationships between the 17 Australian native Sorghum species and the cultivated species, with several studies contradictory in their findings. T...

The identification and characterisation of alleles of sucrose phosphate synthase gene family III in sugarcane
Little is known about the extent of allelic diversity of genes in the complex polyploid, sugarcane. Using sucrose phosphate synthase (SPS) Gene (SPS) Family III as an example, we have amplified and sequenced a...

Robust allele-specific polymerase chain reaction markers developed for single nucleotide polymorphisms in expressed barley sequences
Many methods have been developed to assay for single nucleotide polymorphisms (SNPs), but generally these depend on access to specialised equipment. Allele-specific polymerase chain reaction (AS-PCR) is a meth...

Low efficiency of pseudotestcross map** design was consistent with limited genetic diversity and low heterozygosity in hoop pine (Araucaria cunninghamii, Araucariaceae)
Linkage maps were prepared for two Araucaria cunninghamii individuals (coded H15 and Gil24) using the pseudotestcross strategy in a wide interprovenance cross. The maternal map for individual H15 contains 14 link...
