Plants or tissues can be regenerated through various pathways. Like animal regeneration, cell totipotency and pluripotency are the molecular basis of plant regeneration. Detailed systematic studies on Arabidopsis thaliana gradually unravel the fundamental mechanisms and principles underlying plant regeneration. Specifically, plant hormones, cell division, epigenetic remodeling, and transcription factors play crucial roles in reprogramming somatic cells and reestablishing meristematic cells. Recent research on basal non-vascular plants and monocot crops has revealed that plant regeneration differs among species, with various plant species using distinct mechanisms and displaying significant differences in regenerative capacity. Conducting multi-omics studies at the single-cell level, tracking plant regeneration processes in real-time, and deciphering the natural variation in regenerative capacity will ultimately help understand the essence of plant regeneration, improve crop regeneration efficiency, and contribute to future crop design.
植物或组织可以通过多种途径再生。与动物再生一样，细胞全能性和多能性是植物再生的分子基础。对拟南芥的详细系统研究逐渐揭示了植物再生的基本机制和原理。具体来说，植物激素、细胞分裂、表观遗传重塑和转录因子在重编程体细胞和重建分生细胞方面发挥着关键作用。最近对基生非维管束植物和单子叶作物的研究表明，植物再生在物种间存在差异，不同植物物种使用不同的机制，再生能力存在显著差异。在单细胞水平进行多组学研究，实时跟踪植物再生过程，并解析再生能力的自然变异，最终将有助于理解植物再生的本质，提高作物再生效率，并为未来的作物设计做出贡献。
