Lefrancois P, Rockmill B, Xie P, Roeder G, Snyder M
PLoS Genet
. 2016 Oct;
12(10):e1006347.
PMID: 27768699
During meiosis, chromosomes undergo a homology search in order to locate their homolog to form stable pairs and exchange genetic material. Early in prophase, chromosomes associate in mostly non-homologous pairs,...

Yellman C, Roeder G
PLoS One
. 2015 Jun;
10(6):e0128604.
PMID: 26090959
Cdc14 phosphatase is a key regulator of exit from mitosis, acting primarily through antagonism of cyclin-dependent kinase, and is also thought to be important for meiosis. Cdc14 is released from...

Rockmill B, Lefrancois P, Voelkel-Meiman K, Oke A, Roeder G, Fung J
PLoS Genet
. 2013 Nov;
9(10):e1003932.
PMID: 24204324
Spo11 is the topoisomerase-like enzyme responsible for the induction of the meiosis-specific double strand breaks (DSBs), which initiates the recombination events responsible for proper chromosome segregation. Nineteen PCR-induced alleles of...

Lefrancois P, Auerbach R, Yellman C, Roeder G, Snyder M
PLoS Genet
. 2013 Jan;
9(1):e1003209.
PMID: 23349633
Accurate chromosome segregation requires centromeres (CENs), the DNA sequences where kinetochores form, to attach chromosomes to microtubules. In contrast to most eukaryotes, which have broad centromeres, Saccharomyces cerevisiae possesses sequence-defined...

Newnham L, Jordan P, Rockmill B, Roeder G, Hoffmann E
Proc Natl Acad Sci U S A
. 2010 Jan;
107(2):781-5.
PMID: 20080752
Crossing over establishes connections between homologous chromosomes that promote their proper segregation at the first meiotic division. However, there exists a backup system to ensure the correct segregation of those...

MacQueen A, Roeder G
Curr Biol
. 2009 Sep;
19(18):1519-26.
PMID: 19765989
Background: Homolog pairing, synaptonemal complex (SC) assembly (chromosome synapsis), and crossover recombination are essential for successful meiotic chromosome segregation. A distinguishing feature of meiosis in budding yeast and mammals is...

Tsubouchi T, MacQueen A, Roeder G
Genes Dev
. 2008 Dec;
22(22):3217-26.
PMID: 19056898
Previous studies of synaptonemal complex assembly in budding yeast have suggested that chromosome synapsis initiates at the sites of crossing over. The data presented here, however, indicate that centromeric regions...

Chen S, Tsubouchi T, Rockmill B, Sandler J, Richards D, Vader G, et al.
Dev Cell
. 2008 Aug;
15(3):401-415.
PMID: 18691940
Tight control of the number and distribution of crossovers is of great importance for meiosis. Crossovers establish chiasmata, which are physical connections between homologous chromosomes that provide the tension necessary...

Busygina V, Sehorn M, Shi I, Tsubouchi H, Roeder G, Sung P
Genes Dev
. 2008 Mar;
22(6):786-95.
PMID: 18347097
Two RecA orthologs, Rad51 and Dmc1, mediate homologous recombination in meiotic cells. During budding yeast meiosis, Hed1 coordinates the actions of Rad51 and Dmc1 by down-regulating Rad51 activity. It is...

Mitra N, Roeder G
Genetics
. 2007 Apr;
176(2):773-87.
PMID: 17435220
During meiotic prophase, assembly of the synaptonemal complex (SC) brings homologous chromosomes into close apposition along their lengths. The Zip1 protein is a major building block of the SC in...
