Seminar with Yong-Ling Ruan

On 12 June Professor Yong-Ling Ruan, Director of Australia-China Research Centre for Crop Improvement and formal Head of Biological Science Department at the University of Newcastle, Australia will give a seminar.

Regulation of plant development by sucrose metabolism for food and fibre production

Sucrose metabolism couples with sugar transport to control the flow of carbon as nutrients, energy source and signaling moecules from subcellular to whole plant levels. As such, sucrose metabolism plays pivotal roles in plant development such as flowering, seed set, branching or tillering and their stress responses.

Given carbohydrates including starch and cellulose account for ~ 90% of plant biomass and they all originate from sucrose, understanding the molecular control of sucrose metabolism has become a pressing task for designing innovative approaches to sustain and improve crop yield. We have identified a cohort of key genes/ proteins that control carbon import into, and utilization within, reproductive organs in cotton, tomato and Arabidopsis.

This presentation will highlight how the expression of these genes or the activities of their encoded proteins regulate cell differentiation, phloem unloading and male and female fertilities for food and fiber production.

Yong-Ling Ruan is Professor in Plant Biology and Director of Australia-China Research Centre for Crop Improvement and formal Head of Biological Science Department at the University of Newcastle, Australia.

He focuses his research on identification and manipulation of genetic bottlenecks that limit assimilate allocation to, and utilization within, harvestable organs for improving plant fertility, fitness and food and fibre production.
