Uncovering the molecular components of plant responses to cell wall signals
Grant number: DE170100054 | Funding period: 2017 - 2019
This project aims to discover mechanisms of plant cell wall signalling and modify plant cell walls for improved food, textiles, building materials and renewable biofuels without inadvertently activating cell wall signalling. However, attempts to improve cell walls have been ineffective because it is not known how plants use cell wall signalling to sense and compensate for cell wall changes. This project expects to develop both a genetic screen to find mutants defective in cell wall signal transduction and a bioinformatic tool to compare genomes across species and discover cell wall signalling components. Potential benefits include addressing Australian research priorities: Food, Environmenta..View full description
