Evolution of halophytes: a phyloinformatic approach to understanding and exploiting the traits underlying salt-tolerance in plants. Salinity is an increasing burden on the Australian economy & environment, with >2 million ha of salt-affected land, at an annual cost to agriculture over $187 million. One solution is to exploit naturally salt-tolerant plants to increase productive agricultural land and restore salt-affected environments. To do this, we must increase basic knowledge of the diversity ....Evolution of halophytes: a phyloinformatic approach to understanding and exploiting the traits underlying salt-tolerance in plants. Salinity is an increasing burden on the Australian economy & environment, with >2 million ha of salt-affected land, at an annual cost to agriculture over $187 million. One solution is to exploit naturally salt-tolerant plants to increase productive agricultural land and restore salt-affected environments. To do this, we must increase basic knowledge of the diversity & distribution of salt-tolerance. This project is the first to use DNA sequences from thousands of species to understand the evolution of salt-tolerance in order to provide the foundation for the development of new crop varieties, selection of species that can be developed for bioremediation, and identification of traits that will be profitable targets for breeding programs.

Safeguarding honeybees: understanding host-parasite interactions at the level of proteins. Parasites are responsible for dramatic declines of honeybee populations resulting in a loss of pollination services and posing a threat to food production and ecosystem stability. This project will study the honeybee immune system and its interactions with bee parasites on the molecular scale, which will be important to guide future bee breeding.
Systematics and coevolution of insect herbivores on casuarinas: testing phylogenetic congruence for selection of plant biocontrol agents. The casuarinas (sheoaks) are a significant component of the Australian floral landscape. Associated with them are many co-evolved insects, some of which may prove useful as biocontrol agents against Casuarina weeds. Using morphological taxonomy combined with a novel molecular approach, we will compare the co-evolution of psyllids, scale and gall insects, and w ....Systematics and coevolution of insect herbivores on casuarinas: testing phylogenetic congruence for selection of plant biocontrol agents. The casuarinas (sheoaks) are a significant component of the Australian floral landscape. Associated with them are many co-evolved insects, some of which may prove useful as biocontrol agents against Casuarina weeds. Using morphological taxonomy combined with a novel molecular approach, we will compare the co-evolution of psyllids, scale and gall insects, and weevils with that of the casuarinas. This project will have significant implications for conservation and regeneration of casuarinas in the Australian context and the selection of specific biocontrol agents against casuarinas as environmental weeds.Read moreRead less

Resolving the classification and evolutionary history of the eucalypts. This collaborative project addresses the need to achieve a stable classification of the eucalypts, Australia's most ecologically and commercially important trees. The industry partners are lead agencies with responsibility for classification and identification of biodiversity, delivering taxonomic knowledge for end-users. Despite molecular studies in the last decade, the phylogenetic relationships of a number of the major ....Resolving the classification and evolutionary history of the eucalypts. This collaborative project addresses the need to achieve a stable classification of the eucalypts, Australia's most ecologically and commercially important trees. The industry partners are lead agencies with responsibility for classification and identification of biodiversity, delivering taxonomic knowledge for end-users. Despite molecular studies in the last decade, the phylogenetic relationships of a number of the major subgroups of the eucalypts are unknown. We will sequence new regions of DNA and combine this with morphological data to resolve the relationships of the eucalypt lineages, and hence their classification. Phylogenetic analysis also aids identification of high-value areas for conservation of relictual species.Read moreRead less
