Variations of these activities were checked in the transfer cells of the cotyledonary node in the intact or decapitated plant. They were also studied in the shoot apex of both inhibited (G0state) and released cotyledonary buds, during the transitions G1–S orG2–M. The adenylate cyclase ...
A discriminant vector is calculated and used to classify single sweeps from different subjects. The selected averaging shows an increasing of the signal to noise ratio for every tested subject specially for the method based on Gaussian curves.Cheston, PaulBibliogr...
