Total S phase was measured for wild-type cells undergoing meiS and mitS. Early replication origins were mapped in mitS in wild-type cells, and in meiS for wild-type, sml1 delete, rec8 delete and spo11 delete cells. Comparative genome hybridization was used to measure the kinetics and final extent of...
ORGANISM(S): Saccharomyces cerevisiae 
Spo11-mediated DNA double strand breaks (DSBs) that initiate meiotic recombination are temporally and spatially controlled. The meiotic cohesin Rec8 has been implicated in regulating DSB formation, but little is known about the features of their interplay. To shed light on this point, we investigate...

We previously demonstrated that inactivation of the replication checkpoint via a mec1 mutation led to chromosome breakage at replication forks initiated from virtually all origins of replication, after transient exposure to hydroxyurea (HU), an inhibitor of ribonucleotide reductase. Furthermore, we...

The meiotic cell division reduces the chromosome number from diploid to haploid to form gametes for sexual reproduction. Although much progress has been made in understanding meiotic recombination and the two meiotic divisions, the processes leading up to recombination, including the prolonged pre-m...

Upper and lower parts (flanks) of rice (Oryza sativa sp. japonica) shoot bases at 0.5 h and 6 h after gravistimulation was used for expression analysis in control and gravistimulated samples.Targets from biological replicates of both control and gravistimulated samples were generated and expression ...

We previously demonstrated that inactivation of the replication checkpoint via a mec1 mutation led to chromosome breakage at replication forks initiated from virtually all origins of replication, after transient exposure to hydroxyurea (HU), an inhibitor of ribonucleotide reductase. Furthermore, we...

Spatial metabolomics using mass spectrometry imaging (MSI) is a powerful tool to map hundreds to thousands of metabolites in biological systems. One major challenge in MSI is the annotation of m/z values, which is substantially complicated by background ions introduced throughout the c...
