Abstract: lant somatic embryogenesis is the manifestation of cell totipotency. Somatic cell initiates embryo development under appropriate conditions. Although this phenomenon has been reported for more than fifty years, some details are not clear,such as mechanism of embryogenic reacquisition from mature explants, exogenous/endogenous factors how to regulate embryogenic reacquisition, the key molecular steps of embryogenic reacquisition, regulation of signal network during embryogenic reacquisition. Acquisition of embryogenic competence is an interesting scientific question. This article reviews inducible factors of embryogenic competence, physiological and biochemical markers of embryogenic competence and specific genes, miRNA regulation and proteins related to embryogenic competence.
