Plant cells have a powerful capacity in their propagation to adapt to environmental change, given that a single plant cell can give rise to a whole plant via somatic embryogenesis without the need for fertilization. The reprogramming of somatic cells into totipotent cells is a critical step in somatic embryogenesis. This process can be induced by stimuli such as plant hormones, transcriptional regulators and stress. Here, we review current knowledge on how the identity of totipotent cells is determined and the stimuli required for reprogramming of somatic cells into totipotent cells. We highlight key molecular regulators and associated networks that control cell fate transition from somatic to totipotent cells. Finally, we pose several outstanding questions that should be addressed to enhance our understanding of the mechanisms underlying plant cell totipotency.

植物细胞全能性：深入了解细胞重编程

考虑到单个植物细胞可以通过体细胞胚胎发生而无需受精，从而产生一整株植物，因此植物细胞在繁殖方面具有强大的能力来适应环境变化。体细胞重编程为全能细胞是体细胞胚胎发生的关键步骤。这个过程可以由刺激物诱导，例如植物激素、转录调节剂和压力。在这里，我们回顾了关于如何确定全能细胞的身份以及将体细胞重编程为全能细胞所需的刺激的当前知识。我们强调了控制细胞命运从体细胞到全能细胞转变的关键分子调节器和相关网络。最后，
