nr 2

114-121

The effect of salicylic acid (SA) applied during the proliferation phase of cell suspension in vitro regeneration system of Medicago sativa L. on cell suspension growth, production of somatic embryos and their following development, germination and conversion were examined. SA is a potent inhibitor of the above processes. It is suggested that endogenous jasmonates are of some importance in regulation of somatic embryogenesis.

The review article presents data on the ethylene emanation by bacteria, the two different pathways of its biosynthesis in these microorganisms and the role of ethylene in plant pathogenesis. ACC deaminase from Pseudomonas and Enterobacter spp., which catalyses the hydrolytic cleavage of ACC in higher plants was also discussed.
