Candida glabrata Yap6 Recruits Med2 To Alter Glycerophospholipid Composition and Develop Acid pH Stress Resistance.

ABSTRACT: Candida glabrata is a high-performance microbial cell factory for the production of organic acids. To elucidate the role of the C. glabrata Mediator tail subunit Med2 (CgMed2) at pH 2.0, we deleted or overexpressed CgMed2 and used transcriptome analysis to identify genes that are regulated by CgMed2. At pH 2.0, the deletion of CgMed2 resulted in a cell growth decrease of 26.1% and a survival decrease of 32.3%. Overexpression of CgMed2 increased cell growth by 12.4% and cell survival by 5.9% compared to the wild-type strain. Transcriptome and phenotypic analyses identified CgYap6 as a transcription factor involved in acid pH stress tolerance. Deletion of CgYap6 caused growth defects, whereas its overexpression enhanced cell grow
