Summary
Reducing uncertainty in prediction of leaf respiration in a changing world. This project aims to advance our understanding of responses of carbon dioxide (CO2) release by leaf (leaf respiration) to sustained changes in CO2 and temperature. Leaf respiration in terrestrial forests releases yearly CO2 that is two to four times higher than CO2 emitted by human activities, but its response to climate change is not well understood. The project expects to generate new knowledge on mechanisms underlying ....Reducing uncertainty in prediction of leaf respiration in a changing world. This project aims to advance our understanding of responses of carbon dioxide (CO2) release by leaf (leaf respiration) to sustained changes in CO2 and temperature. Leaf respiration in terrestrial forests releases yearly CO2 that is two to four times higher than CO2 emitted by human activities, but its response to climate change is not well understood. The project expects to generate new knowledge on mechanisms underlying responses of leaf respiration to these climate change variables, separately and combined. Expected outcome is to deliver criteria that enable dynamic changes in leaf respiration to be predicted in climate models. Results should benefit improved forecast of feedback between Australian forests' carbon cycling and climate.Read moreRead less
Genome evolution & adaptation of the multinuclear wheat stripe rust fungus. Animals and plants package their genomes into a single nucleus within each cell. In contrast, millions of fungal species accommodate multiple nuclei containing individual haploid genomes. It is currently unknown what the evolutionary implications are for this unusual genome division into multiple nuclei. Here we explore the evolutionary consequences of genome division into multiple nuclei for the first time by applying c ....Genome evolution & adaptation of the multinuclear wheat stripe rust fungus. Animals and plants package their genomes into a single nucleus within each cell. In contrast, millions of fungal species accommodate multiple nuclei containing individual haploid genomes. It is currently unknown what the evolutionary implications are for this unusual genome division into multiple nuclei. Here we explore the evolutionary consequences of genome division into multiple nuclei for the first time by applying cutting edge genome biology tools and algorithms. The economically significant study system is the devastating wheat stripe rust fungus. This pathogen costs Australian farmers over $100 million a year. New understanding is expected to lead to better disease management, reduced fungicide applications, and increased yields.Read moreRead less
