摘要

With the evolution of specific perception mechanisms, molecules such as auxins, cytokinins, gibberellins, abscisic acid and ethylene, acquired a hormonal role during the evolution of land plants. These hormones induce cell division, cell elongation and cell differentiation by regulating the expression of transcription factors and cell type specific genes. A limited number of modules and signalling pathways have been utilized during hormonal signal transduction. The specificity arises at the level of receptors, transcription factors, post-translational modifications of signalling agents and crosstalk between different hormones. The signalling pathways are turning out to be highly conserved in plants and animals.
