Exploring barley germplasm for yield improvement under sulphur-limiting environments
MetadataShow full item record
This chapter reviews genetic diversity in barley and its role in improving varieties, including adaptation to abiotic stresses. Sulphur is an essential macronutrient required in plants for normal growth and development. Its deficiency in agricultural soils reduces grain yield and grain quality traits. Studies conducted with barley and wheat varieties demonstrate substantial variations among crops and varieties in their response to application of different levels of sulphur. The chapter looks at factors affecting sulphur nutrition in barley and the potential role of genetic differences in breeding more resilient varieties.

Gene-set association and epistatic analyses reveal complex gene interaction networks affecting flowering time in a worldwide barley collectionHe, Tianhua; Hill, C.; Angessa, T.; Zhang, X.; Chen, Kefei; Moody, D.; Telfer, P.; Westcott, S.; Li, C. (2019)Single-marker genome-wide association studies (GWAS) have successfully detected associations between single nucleotide polymorphisms (SNPs) and agronomic traits such as flowering time and grain yield in barley. However, ...
Heterologous Expression of the Pyrenophora tritici-repentis Effector Proteins ToxA and ToxB, and the Prevalence of Effector Sensitivity in Australian Cereal CropsMoffat, Caroline ; See, Pao Theen; Iagallo, Elyce M; Oliver, Richard P (2019)Here, we evaluate the expression of the proteinaceous effectors ToxA and ToxB, produced by the necrotrophic fungal pathogen Pyrenophora tritici-repentis, which confer tan spot disease susceptibility on wheat. These ...
