Thidiazuron Influenced Morphogenesis in Some Medicinal Plants

Thidiazuron (N-phenyl-N′-1,2,3-thiadiazol-5-ylurea; TDZ) is an artificial plant growth regulator that is widely used in plant tissue culture. Due to its dynamic role in plant tissue culture, it has gained ample attention for several workers since the past decades. Wide array of TDZ-influenced physiological responses are reported in different medicinal plant species. TDZ has shown both auxin- and cytokinin-like effects, although, chemically, it is totally different from commonly used auxins and cytokinins. A number of physiological and biochemical events in cells are induced or enhanced by TDZ, but the mode of action of TDZ is yet to explore. However, varieties of underlying mechanisms have been revealed in several reports to defend the morphogenic events induced by the application of TDZ. Some reports emphasized that TDZ may modify endogenous plant growth regulators, either directly or indirectly, and produce reactions in cell/tissue, necessary for its division/regeneration. Other possibilities include modification in cell membrane, fluidity, nutrient uptake, transport and assimilation, etc. In this review, recent advancements in TDZ application in plant sciences are discussed.
