The commitment of eukaryotic cells to division normally occurs during the G1 phase of the cell cycle. In mammals D-type cyclins regulate the progression of cells through G1 and therefore are important for both proliferative and developmental controls. Plant CycDs (D-type cyclin homologs) have been identified, but their precise function during the plant cell(More)
The respective involvement of transcriptional and post-transcriptional mechanisms in coupling H3 and H4 histone gene expression to the S phase of the cell cycle has been studied in synchronized tobacco cells. Induction of histone gene expression at the G1/S transition is shown to be essentially directed by an increase in the transcription rate in response(More)
Maritime surveillance needs to be improved in order to provide a worldwide, independent of national borders, continuous, systematic and reliable maritime security and safety system for the benefits of end users: EU agencies, Customs, Coast Guard, Navies, Private Ventures, ... The AIS (Automatic Identification System) is an existing VHF anti collision(More)
The first complete amino acid sequence of a H1 histone of a monocotyledonous plant was deduced from a cDNA isolated from a maize library. The encoded H1 protein is 245 amino acid-long and shows the classical tripartite organization of this class of histones. The central globular region of 76 residues shows 60% sequence homology with H1 proteins from dicots(More)
