Phytohormones in Seed and Fruit Development

摘要: Research on hormone regulation of seeds and fruits has developed considerably over the last few years with, in background, aim improving seed quality. Major projects have thus been launched, for example, concerning soybean USA. Several reviews recently surveyed evolution levels their possible roles during maturation, case gibberellins [22], cytokinins [40] or abscisic acid [5, 23]. After consideration mechanisms levels, attention will be focused role fruit development. In majority studies, conclusions are based simultaneous occurrence peak values content certain morphological biochemical changes, results an application growth regulators to intact plants. Karssen [21] discussed limitations these experimental approaches. Nooden [28], his presentation integration pod development monocarpic senescence, shown how difficult it is interpret a study whole plant. However, recent anatomical, physiological, research furnished us with tools, which indispensible better understanding at different hormones act. Thus, new interest storage proteins [19, 30]. The precise analytical techniques (immuno-assay, use cDNA clones) made possible, species, characterize main monitor kinetics accumulation.
