Novel BAP degradation pathway during adventitious caulogenesis in Pinus pinea L. cotyledons
Background Cytokinins (CKs) are a group of phytohormones which probably regulate the growth, development, and metabolism of all plants. The aromatic CK benzyladenine (BA) has been widely applied in in vitro culture for inducing shoot organogenesis. Our study of endogenous cytokinin profiles during the caulogenic process based on mature cotyledons of stone pine (Pinus pinea L.) showed a novel me...
متن کاملMultisite inhibition of Pinus pinea isocitrate lyase by phosphate.
Our results show that the phosphate ion is a nonlinear competitive inhibitor of Pinus pinea isocitrate lyase. In addition, this compound induces a sigmoidal response of the enzyme, which usually exhibits standard Michaelis-Menten kinetics. This peculiar behavior of P. pinea isocitrate lyase could be explained by a dimer (two-site) model, in which phosphate binds cooperatively, but the affinity ...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Chemical profiling of Portuguese Pinus pinea L. nuts.
BACKGROUND The first detailed chemical characterisation of Portuguese pine nut (Pinus pinea L.) is reported concerning proximate composition, fatty acid, mineral and vitamin contents. RESULTS Based on the analysis of 27 different populations, pine nuts were characterised by high contents of fat (47.7 g per 100 g dry matter (DM)), protein (33.8 g per 100 g DM) and phosphorus (1130 mg per 100 g...
متن کاملQuantitative trait loci associated with adventitious shoot formation in tissue culture and the program of shoot development in Arabidopsis.
Arabidopsis ecotypes, Columbia (Col) and Landsberg erecta (Ler), differ in their capacity to regenerate shoots in culture, as do many other cultivars and varieties of the same plant species. Recombinant inbred (RI) lines derived from a cross of Col x Ler were scored for shoot regeneration, and the Arabidopsis genome was scanned using composite interval mapping for loci associated with shoot reg...
