Cet ouvrage propose des protocoles d'observations et d'expériences simples réalisables dans une classe de biologie et physiologie végétales du secondaire. Pour chaque expérience, le but recherché, le matériel nécessaire, le protocole expérim
RNase and transaminase activities were analysed for mechanically and enzymatically prepared protoplasts from Allium Cepa roots. The comparative analyses at three root regions show that the enzymes were less active in the protoplasts than in the cells

Physicochemical and enzymic approaches were used to characterize highly methylated pectins isolated from mung bean hypocotyl cell walls. Young cell walls were particularly rich in rhamnogalacturonan-1-like polysaccharides, the galacturonic units of w

The fine structure of a beta-)1----4)-linked glucomannan from Asparagus officinalis has been determined by n.m.r. analysis of the oligosaccharides obtained by acidic and enzymic hydrolyses. Cleavage of the glucomannan with beta-D-mannase from Aspergi

ResumeDans les cellules vegetales, la structure de la paroi impose des limites a l'effet de la pression de turgescence. La croissance induite par l'auxine resulte de modifications enzymatiques de cette structure. La nature des liaisons rompues differ

Protoplasts were isolated from successive sections along the mung bean hypocotyl. High yields were obtained with mature tissues. The fatty acid composition of the protoplasts was similar to that found in the original cells which indicates that no maj
