Regeneration serves as a self-protective mechanism that allows a tissue or organ to recover its entire form and function after suffering damage. However, the regenerative capacity varies greatly within the plant kingdom. Primitive plants frequently display an amazing regenerative ability as they have developed a complex system and strategy for long-term survival under extreme stress conditions. The regenerative ability of dicot species is highly variable, but that of monocots often exhibits extreme recalcitrance to tissue replenishment. Recent studies have revealed key factors and signals that affect cell fate during plant regeneration, some of which are conserved among the plant lineage. Among these, several members of the ETHYLENE RESPONSE FACTOR (ERF) transcription factors have been implicated in wound signaling, playing crucial roles in the regenerative mechanisms after different types of wounding. An understanding of plant regeneration may ultimately lead to an increased regenerative potential of recalcitrant species, producing more high-yielding, multi-resistant and environmentally friendly crops and ensuring the long-term development of global agriculture.
再生是一种自我保护机制，使组织或器官在遭受损伤后能够恢复其全部形态和功能。然而，在植物界中，再生能力差异很大。原始植物经常表现出惊人的再生能力，因为它们已经发展出一种复杂的系统和策略，以在极端压力条件下长期生存。双子叶植物的再生能力变化很大，但单子叶植物的组织补充通常表现出极强的抗性。最近的研究揭示了影响植物再生过程中细胞命运的关键因素和信号，其中一些在植物谱系中是保守的。在这些因素中，乙烯反应因子（ERF）转录因子的几个成员被牵涉到伤口信号中，在不同类型的伤口后再生机制中发挥着关键作用。对植物再生的理解最终可能会提高抗性物种的再生潜力，产生更高产、多抗性和环境友好型的作物，并确保全球农业的长期发展。
