WebIntroduction. The formation of adventitious shoots is a complex process that involves the participation of plant growth regulators (PGRs), mainly auxins and cytokinins, with multiple signaling pathways (Kareem et al. 2016; Sang et al. 2024; Tian et al. 2024; Ikeuchi et al. 2024).Three phases have been differentiated during the in vitro caulogenic process: … WebNov 18, 2003 · These organs develop from meristems at the tip of the stem and the root that are called the shoot apical meristem (SAM) and the root apical meristem, respectively. In dicots, the SAM is formed between the two cotyledon primordia during embryogenesis.
