The 6th Intl Symposium on Production and Establishment of Micropropagated Plants will focus on the following sessions: Understanding in vitro growth The development of tissue culture system is a rigorous procedure that involves genetic, physiological and developmental approaches as well requires the optimization of chemical, physical and environmental factors of growth. In this section, which will be expanded in two parts (1 & 2), lectures, oral and poster presentations addressed to understand the mechanisms which are underlying the regeneration systems and the in vitro growth will be considered. Managing micropropagation process Despite the advances made in plant tissue culture, the application of this technique is still hampered by various physiological and developmental problems. This section will face several aspects faced during the managing of the micropropagation process e.g. contamination problems, abnormal growth, lack of juvenility, shoot-tip necrosis, fasciation, tissue proliferation, epigenetic changes and somaclonal variation. This section will covers part 3 & 4 of the Symposium. Rooting and establishment of micropropagated plantlets Rooting and establishment are two crucial steps in the micropropagation process and this section will deal with underlying mechanism of rooting process, rooting recalcitrance, acclimatization losses and field evaluation of ex vitro plantlets Micropropagation industry: new niches and roles for tissue culture companies Since the general goal of our Symposium is to create an interaction between the scientific aspect and the application point of view of the in vitro management, we have thought to dedicate a specific session to the micropropagation industry. Industrial laboratories are welcome as well as researchers whose research is closely developed with the micropropagation industry to face themes related to scaling up, bioreactors, new niches of application e.g. root culture to produce secondary metabolites or commercial micropropagation for crops desirable for new niche markets.
