We have characterised an Arabidopsis xrcc1 mutant and developed quantitative analysis of the kinetics of appearance and loss of c-H2AX foci as a tool to measure DSB repair in

Temperature, rainfall and wind variables underlie environmental adaptation in natural populations of Drosophila melanogaster

We used the BayPass software to identify single nucleotide polymorphisms (SNPs) and transposable ele- ments (TEs) showing signature of adaptive differentiation across

Polysaccharide Complexes in Full-Grown Oocytes of the Newt, Pleurodeles, and Changes in their Distribution During Progesterone-Induced Maturation. (glycogen granules/oocyte maturation/polysaccharide complexes/urodele amphibian)

In the present study, large amounts of polymerized electron-dense granules were seen in the peripheral cytoplasm of full-grown immature and maturing oocytes of the
