| transcription reactivation during the first meiotic prophase in bugs is not dependent on synapsis. | during meiosis, transcription is precisely regulated in relation to the process of chromosome synapsis. in mammals, transcription is very low until the completion of synapsis in early pachytene, and then reactivates during mid pachytene, up to the end of diplotene. moreover, chromosomes or chromosomal regions that do not achieve synapsis undergo a specific process of inactivation called meiotic silencing of unpaired chromatin (msuc). sex chromosomes, which are mostly unsynapsed, present a specia ... | 2017 | 26899781 |
| morphological, biogeographical and molecular evidence of carpocoris mediterraneus as a valid species (hemiptera: pentatomidae). | carpocoris mediterraneus tamanini, 1958, synonymized with carpocoris fuscispinus (boheman, 1851) by ribes et al. (2007), is restored to the species level. the shape of the pronotum is a good diagnostic character to distinguish the two species. the existence of two valid species is supported by geographical distribution patterns in western europe: mediterranean-atlantic for c. mediterraneus, and continental for c. fuscispinus. in france and spain, in some areas, the two species are found in sympa ... | 2013 | 24699602 |
