We have examined the periodic expression of genes through the cell cycle in cultures of the human pathogenic fungus Candida albicans synchronized by mating pheromone treatment. Close to genes show increased expression during the G1, S, G2, or M transitions of the C.

albicans orthologue of a key Cdk1 G1/S transition inhibitor Sic1, is also periodically transcribed at this time. Ace2, which is expressed during the preceding G2/M phase and acts through the mini-motif CCAGC A / C (Candida clade p value; p = × 10 −20), seems to be a major transcriptional regulator of the M/G1 C.

During infection, Candida undergoes a complex series of morphogenetic transitions, switching among a round, budding yeast form, a budding psuedohyphal form, and true tubular hyphae.

Physiological levels of CO 2 have a profound impact on prominent biological attributes of the major fungal pathogen of humans, Candida ed CO 2 induces filamentous growth and promotes white-to-opaque switching.

However, the underlying molecular mechanisms of CO 2 sensing in C. albicans are insufficiently understood. Here we identify the transcription factor Flo8 as a key The sensing and efficient utilization of environmental nutrients are critical for the survival of microorganisms in environments where nutrients are limited, such as within mammalian hosts.

Candida albicans is a common member of the human microbiota as well as an opportunistic fungal pathogen. The amide derivative sugar N-acetlyglucosamine (GlcNAc) is an important signaling molecule for C Introduction. The medical importance and interesting biological properties of Candida albicans have resulted in it becoming a focus of intense research.

Methodologically, this research has borrowed extensively from the sophisticated molecular technology developed in its distant relative, the budding yeast Saccharomyces cerevisiae (for reviews see 10; 6).

Aaron D. Hernday, Alexander D. Johnson, in Methods in Enzymology, Abstract. Candida albicans is an opportunistic fungal pathogen of humans. Although a normal part of our gastrointestinal flora, C. albicans has the ability to colonize nearly every human tissue and organ, causing serious, invasive infections.

In this chapter we describe current methodologies used in molecular genetic /candida-albicans. The ability of Candida albicans to switch cellular morphologies is crucial for its ability to cause infection.

Because the cell cycle machinery participates in Saccharomyces cerevisiae filamentous growth, we characterized in detail the two C. albicans B-type cyclins, CLB2 and CLB4, to better understand the molecular mechanisms that underlie the C. albicans morphogenic ://.

C. albicans lacking Ncep cannot survive in low CO2 concentrations, e.g., in atmospheric growth conditions. Candida carbonic anhydrases are orthologous to the Saccharomyces cerevisiae enzyme, which had originally been detected as a
