Potential Role Of Rta3 And Gnp3 Transport Genes In The Quorum Sensing Response Of Candida Albicans, John G. Magnuson
Potential Role Of Rta3 And Gnp3 Transport Genes In The Quorum Sensing Response Of Candida Albicans, John G. Magnuson
Undergraduate Honors Theses
Quorum sensing (QS) is a mechanism of communication between cells to coordinate biological activities. In the opportunistic fungal pathogen Candida albicans, QS is important for regulating the organism’s ability to change morphology from a yeast form to a hyphal form. Previously, our laboratory identified several genes involved in polymicrobial communication between C. albicans and three bacterial species. We hypothesize that interspecies communication and QS utilize the same genetic pathways to control C. albicans morphological behavior. In this study, two transport genes, RTA3 and GNP3, and their involvement in QS were examined. To test whether these two genes participate in QS, …

Candida albicans is an opportunistic pathogen that is present in the normal flora in a majority of individuals. One key factor in C. albicans virulence is the ability to change its morphology from yeast to an elongated or hyphal form. The regulation of this morphogenesis relies in part upon quorum sensing (QS) molecules. C. albicans often exists as part of a mixed culture alongside other microbes and is influenced by their presence as well as the presence of QS molecules that they produce. In this study, a library of diploid homozygous transcriptional regulator knockout (TRKO) mutants were screened to identify …
