Molecular genetic analysis of genes controlling morphogenesis: Dimorphic switching in the fungus Penicillium marneffei. Fungi exist in two predominant growth forms; unicellular yeast and multicellular mould (filamentous hyphae). Some fungi can alternate between these two forms in response to environmental stimuli, a process known as dimorphic switching. The cells of these two forms have distinctive shapes and physiological capacities established by genome-wide expression patterns that are trigge ....Molecular genetic analysis of genes controlling morphogenesis: Dimorphic switching in the fungus Penicillium marneffei. Fungi exist in two predominant growth forms; unicellular yeast and multicellular mould (filamentous hyphae). Some fungi can alternate between these two forms in response to environmental stimuli, a process known as dimorphic switching. The cells of these two forms have distinctive shapes and physiological capacities established by genome-wide expression patterns that are triggered by signalling pathways. This research aims to understand the fundamental mechanisms controlling dimorphic switching using Penicillium marneffei, a model system. P. marneffei switches between yeast and filamentous forms in response to temperature. Uncovering the molecular mechanisms that control dimorphic switching has important implications for biotechnology and medicine.Read moreRead less
Developmental genetics of malaria parasites. This project aims to improve our understanding of malarial genetics. The sexual cycle of malaria parasites occurs in mosquitoes. After sex, parasite progeny multiply to form infective spores that are injected into people by mosquito bite. Development of male and female malaria parasite gametes and their fusion to produce a diploid zygote are well understood, but the subsequent process of meiosis, development of a cyst stage and the sporogenic process ....Developmental genetics of malaria parasites. This project aims to improve our understanding of malarial genetics. The sexual cycle of malaria parasites occurs in mosquitoes. After sex, parasite progeny multiply to form infective spores that are injected into people by mosquito bite. Development of male and female malaria parasite gametes and their fusion to produce a diploid zygote are well understood, but the subsequent process of meiosis, development of a cyst stage and the sporogenic process to create haploid progeny for new infections are poorly understood in molecular genetic terms. The project aims to dissect the unique genetics of these insect stages using a rodent malaria model to generate crosses of different malaria parasite lines to determine when recombination takes effect.Read moreRead less
Genetic and epigenetic control of developmental competence. Development is an important biological process of life and understanding development has important medical and economic benefits for Australia. This research aims to study development using a simple, easily manipulated and well established experimental organism, a fungus, as a model for development in other organisms, including humans. In addition, fungi directly impact on life at many levels. Fungi can be pathogens of humans, other ani ....Genetic and epigenetic control of developmental competence. Development is an important biological process of life and understanding development has important medical and economic benefits for Australia. This research aims to study development using a simple, easily manipulated and well established experimental organism, a fungus, as a model for development in other organisms, including humans. In addition, fungi directly impact on life at many levels. Fungi can be pathogens of humans, other animals or plants significantly affecting our health, agriculture and industry. Fungi are also beneficial to other organisms, especially to many plants, and are used to manufacture pharmaceuticals and enzymes used in the health and biotechnology industries.Read moreRead less
Genetic regulation of developmental competence: molecular mechanisms that establish a competent state. Development is a key biological process for multicellular life. This project will study development using a simple, established experimental organism, a fungus, as a model for development in other organisms, including humans. Moreover, fungi directly impact on life at many levels and understanding their biology has direct benefits for society.
