摘要: Plant growth and development is dependent on numerous environmental endogenous factors. cells are able to respond different signals with very precise reactions using complex signal transduction pathways. A multiplicity of transmitting agents involved in these processes which start perception by receptor molecules, moving the cell nucleus, resulting expression specific genes ending a response can be local or systemic. In most cases, result activating such pathway stimulation repression one several coding for products answer. Therefore, after exogenous receptors has transmitted nucleus (for review see Zentgraf Hemleben 1996). The activation achieved elevating rate transcription initiation at respective promoters. basal formed ubiquitous factors RNA polymerase complemented specifically regulated trans-factors interacting defined cis-elements. concentration trans-factors, their compartmentalization, stage activity multimerization determine rate.
