TY - GEN N1 - jasmonic acid (JA), methyl jasmonate (JA-Me) and their related compoundswhich are designated as jasmonates, are widely distributed in the plant kingdom and show various important biological activities in the regulation of plantgrowth and development, resulting in a consideration that they are putativenew plant hormones. Endogenous levels ofjasmonates, mainly JA, increase rapidly and transiently in plants or their organs under both abiotic and biotic stressconditions, jasmonates consist of an integral part of the signal transductionchain between stress signal(s) and stress response(s). In this article, we focusedon and reviewed the role ofjasmonates in control of differentiation processesin tissue cultures, regeneration and micropropagation, somatic embryo formation, tuber initiation and formation. The involvement of jasmonates intuberization, tuberous root formation and bulb formation was inferred fromtheir ability to induce the processes in vitro, and from changes in the levels ofendogenous jasmonates during the growth of the plants which can account forthe initiation of tuberization. The tuberization and the expansion of cells induced by jasmonates always involve the reorientation of cortical microtubules.Differential effect ofjasmonic acid on cell cycle progression is also presented. Itis still an open question about interactions between jasmonates and other hormones (auxin, ethylene, cytokinins, abscisic acid) in the regulation of meristemactivities, cell cycle and other physiological processes.
