Cloning and characterization of ECE1, a gene expressed in association with cell elongation of the dimorphic pathogen Candida albicans

Year: 1993

Type: article

Abstract: The gene ECE1 (extent of cell elongation 1) was isolated by differential hybridization screening of a Candida albicans cDNA library by using probes derived from populations of yeast cells or hyphae. Expression of this gene was not detected when C. albicans grew as a budding yeast cell but was observed within 30 min after cells had been induced to form hyphae. In all strains tested, regardless of the induction signal, ECE1 expression correlated with the extent of cell elongation. The genomic version of ECE1 was cloned and sequenced. The deduced 271-amino-acid polypeptide consisted of eight tandem repeats of a degenerate 34-amino-acid sequence which contained no discernible homology with other known sequences. An ECE1 null mutant displayed no morphological alterations, which demonstrated that ECE1 is not essential for cell elongation or hypha formation despite the strict morphological association of its expression.
