Journal ArticleDOI
A new role for a yeast transcriptional silencer gene, SIR2, in regulation of recombination in ribosomal DNA
TL;DR: It is demonstrated that Sir2's effect is not restricted to controlling mating type expression, but rather that SIR2 functions in a more general way in the genome.
Journal ArticleDOI
The genetic control of meiosis.
Bruce S. Baker,Adelaide T. C. Carpenter,Michael S. Esposito,Rochelle Easton Esposito,L. Sandler +4 more
TL;DR: This work has shown that mutants with altered meiotic exchange with defective mating-type control of sporulation have an important effect on fertility and this work aims to clarify these effects.
Journal ArticleDOI
The core meiotic transcriptome in budding yeasts
Michael Primig,Roy Williams,Roy Williams,Elizabeth A. Winzeler,Gela G. Tevzadze,Andrew R. Conway,Seung Y. Hwang,Ronald W. Davis,Rochelle Easton Esposito +8 more
TL;DR: High-density oligonucleotide microarrays were used to analyse the genomes and meiotic expression patterns of two yeast strains that display distinct kinetics and efficiencies of sporulation and yielded approximately 1,600 meiotically regulated genes in each strain.
Journal ArticleDOI
Direct evidence for sir2 modulation of chromatin structure in yeast rdna
TL;DR: Deletion and overexpression studies demonstrate that SIR2, but not SIR1, SIR3 or SIR4, is required for this rDNA position effect, and significantly, rDNA transcriptional silencing and rDNA chromatin accessibility respond to Sir2 dosage, indicating that S IR2 is a limiting component required for chromatin modeling in rDNA.
Journal ArticleDOI
A screen for genes required for meiosis and spore formation based on whole-genome expression
Kirsten P. Rabitsch,Attila Tóth,Marta Galova,Alexander Schleiffer,Gotthold Schaffner,Elisabeth Aigner,Christian W. Rupp,Alexandra M. Penkner,Alexandra C. Moreno-Borchart,Michael Primig,Rochelle Easton Esposito,Franz Klein,Michael Knop,Kim Nasmyth +13 more
TL;DR: Reverse genetics using gene expression data is an effective method for identifying new genes involved in specific cellular processes and one of these (MAM1) is essential for the monoorientation of sister kinetochores during meiosis I.
