Abstract:
... Plants have a remarkable regenerative capacity, but it varies widely among species and tissue types. Whether plant cells/tissues initiate regeneration largely depends on the extent to which they are constrained to their original tissue fate. Once cells start the regeneration program, they acquire a new fate, form meristems, and develop into organs. During these processes, the cells must continuous ...

Abstract:
... Nine carbapenem-resistant Acinetobacter baumannii isolates carrying blaOXA-231 and an ISAba1 upstream occAB1 were evaluated. They were clonally related and belonged to ST107. An OXA-143-producing A. baumannii ST107 strain (Ac-148) that did not possess ISAba1 upstream occAB1 was included in the analysis. Reduction in the expression of occAB1 and a 4-fold increase of carbapenem MICs were observed fo ...

Abstract:
... Telomere maintenance mechanism is poorly studied in quiescence, a reversible non-proliferative state. We previously described in fission yeast a new mode of repair of telomeres named STEEx, that specifically operates in post-mitotic cells harboring eroded telomeres. This mechanism, promoted by transcription-induced telomeric recombination, prevents cells to exit properly from quiescence, suggestin ...
