“…In contrast to animals, plants cannot move to withstand damage from adverse environments, so regeneration is an important ability for plants to resist and adapt to their environment [3,4]. The essence of plant regeneration is the process by which cells transform their cell fate after adverse, environmental stress [5], and totipotency or pluripotency is the basis of regeneration [3].…”

“…In tissue culture, the addition of growth hormone or CK can promote the regenerative ability of plant roots or shoots [22]. However, the key finding during tissue culture is that the ratio of added auxin and CK can determine cell fate, a high ratio of auxin promotes root regeneration, while a high ratio of CK promotes shoot regeneration [5]. Studies have confirmed that under natural conditions, plants can promote root regeneration from scratch by endogenous hormones on media without the addition of exogenous growth hormones [2,23].…”

Plant regeneration is a self-repair of the plant body in response to adverse conditions or damaged structures, and root regeneration allows the plant body to better adapt to its environment by supplementing the roots' structure. Previous research has shown that adventitious roots can be made to occur from scratch in two ways. Studies that simulate adventitious root regeneration through natural conditions allow the regeneration process to be broadly divided into three stages: the perception of early signals, the massive accumulation of auxin, and the transformation of cell fate. The strength of regeneration, in turn, is influenced by wounding, stress, hormones, etc. This study mainly reviews the molecular mechanisms of de novo adventitious roots and discusses how the environment, hormones, and its own development in Arabidopsis thaliana.

“…Besides, thidiazuron (TDZ) was recognized as a highly active and less used cytokinin in the stimulation of shoot organogenesis of various plants, including medicinal and endangered plants (Deepa et al, 2018 ; Zhang et al, 2021 ). Some studies have demonstrated that TDZ is more effective than other cytokinins (Bhattacharyya et al, 2016 ; Yücesan, 2018 ).…”

Aloe vera [Aloe vera (L.) Burm. f.] is considered a valuable medicinal plant worldwide due to its remarkable beneficial effects on human health. However, challenges in A. vera propagation hinder meeting the increasing demand in the health and beauty sectors. As an alternative method, in vitro propagation is crucial for the mass production of Aloe plants, which is a rapid method as well. Therefore, the present study aimed to establish an efficient micropropagation protocol for A. vera by in vitro optimization of the effect of different plant growth regulators (PGRs).For shoot proliferation, sterilized explants were inoculated on the Murashige and Skoog (MS) medium supplemented with 6-benzylaminopurine (BAP) and thidiazuron (0.5, 1.0, 2.0, and 4.0 mg/l) in combination with 0.5 mg/l naphthaleneacetic acid (NAA). Subsequently, indole-3-butyric acid (IBA) (1.0, 2.0, and 3.0 mg/l) was used for root induction. It was found that the explants cultured on the MS medium supplemented with 4.0 mg/l BAP + 0.5 mg/l NAA showed the highest percentage of response (90 ± 1.29) for shoot induction within the minimum number of days (5 ± 0.33). The highest number of shoots (2.7 ± 0.36) and length of shoots (4.7 ± 0.42 cm) per explant were also observed with the same concentration of PGRs. However, the highest number of roots (3.2 ± 0.57), length of roots (5.67 ± 0.21 cm), and root induction (80 ± 1.97 %) were noticed within the minimum number of days (11 ± 0.79) on the MS medium supplemented with 1.0 mg/l IBA. Thus, the proposed method is a quick and effective approach for the mass propagation of A. vera with appropriate dosages of auxins and cytokinins, which may allow meeting the increasing commercial demand.
