Blastomyces dermatitidis: SREB null mutant versus wild type at 37oC and 6, 24, and 48-hrs 22oC

ABSTRACT: The goal of this study was to capture the transcriptional response regulated by the GATA transcription factor encoded by SREB during the first 48-hours of the temperature-dependent shift from yeast (37oC) to mycelia (22oC). Gene expression microarrays were used to compare an SREB null mutant (SREBΔ) to an isogenic wild type strain (ATCC 26199). SREB null mutants fail to fully complete the conversion from yeast to sporulating mycelia after a drop in temperature from 37oC to 22oC, and under iron-replete conditions cannot properly repress siderophore biosynthesis. Deletion of SREB in ATCC 26199 produced SREBΔ. The isogenic wild-type strain is ATCC 26199.

ChIP-seq analysis of SREB during yeast phase growth of Blastomyces dermatitidis at 37oC

Project description:ChIP-seq analysis was used to identify B. dermatitidis genes bound by the GATA transcription factor encoded by SREB during growth as yeast at 37oC SREB was engineered to contain an in-frame 3x-hemagglutinin (HA) epitope tag at the C-terminus. The SREB-3xHA construct was under control of its native promoter and contained the 3-untranslated region. Using Agrobacterium tumefaciens, B. dermatitidis ATCC 26199 was transformed with the SREB-3xHA construct (referred to a SREB-3xHA strain in this document). The SREB-3xHA construct was functional because retransformation of SREB? with the construct complented the null mutant. Chromatin was extracted and sheared from ATCC 26199 and SREB-3xHA yeast grown in liquid Histoplasma macrophage medium (HMM) containing 10 ?M iron sulfate (FeSO4) at 37oC. ATCC 26199 was the untagged control strain.

Temperature-controlled inhibition of phyB action

Project description:It has been established that the frequently reported early flowering phenotype of the phyB mutant is very sensitive to small changes in ambient temperature (Halliday et al., 2003). A 6oC drop in temperature to 16oC is sufficient to abolish the pronounced early flowering phyB phenotype observed at 22oC. Using Affymetrix technology we will identify genes that are differentially regulated at 16oC and 22oC in a phyB-specific manner using phyB mutant and wild type seedlings.

Project description:The transcriptome profiles of sporulating vs non-sporulating cells, within an isogenic culture were compared. RNA was isolated from endospore containing cells which were separated from non-spore forming cells using buoyant density gradient centrifugation within an isogenic culture (details in Veening et al, submitted).
