Description

Overall Research Project

The Hy-Gain project (Hy-Gain), funded by the Bill and Melinda Gates Foundation is a multi-party international research project comprising seven world leading teams aiming to develop a novel technology to increase seed yield and productivity in sorghum and cowpea crops for smallholder farmers in sub-Saharan Africa. This exciting 5-year project, is led by QAAFI with the project director, Prof Anna Koltunow, based in the Centre for Crop Science. Hy-Gain aims to ensure the technology is compatible with plant breeding to support the future, rapid delivery of new high yielding sorghum and cowpea hybrids and improved varieties. Hy-Gain involves research work at multiple sites in Queensland (Hermitage at Warwick; Gatton and St. Lucia) and collaboration with five international research organisations and a multinational seed company. The project has some fundamental discovery work, however its key aim is building and testing the utility of the technology in plants under controlled glasshouse and field conditions with evaluations involving input from African sorghum and cowpea breeders. The research objectives span molecular work in the laboratory to field work involving genetic, genomic and transgenic technologies and testing reproductive productivity of plants in glasshouse and in the field. Communication and collaboration between the parties to efficiently achieve goals, protection of discoveries, dissemination of data to the public via scientific publications and web-based media are important outcomes of the project.

PhD Scholarship Project

Heterosis, or hybrid vigour, is agronomically very important however the mechanisms of heterosis are poorly understood. Quantitative heterotic traits in sorghum, including yield related traits, are under complex genetic control and have also been shown to interact with chromatin structure, differential gene expression and presence/absence variation.  This project will characterise the chromatin structure in sorghum and investigate the association between chromatin type and structural variation, using data identified in the sorghum pan-genome. The project will further identify genomic regions, and candidate genes, associated with heterosis using a large diversity panel, to investigate which portions of the genome contribute to quantitative heterotic traits in sorghum. The candidate genes will be further investigated for differential gene expression between hybrids and parent samples from the diversity panel. Several features of sorghum, including its high genetic diversity, relatively small diploid genome, availability of extensive genomic resources, including a pan-genome, make it an excellent experimental system to explore the genome landscape of heterosis and to explore the impact of structural variation and chromatin type on heterosis. This PhD is based at Warwick, Qld.
