| 摘 要： | 莲( Nelumbo nucifera Gaertn.)为莲科、莲属多年水生宿根草本植物。莲子生命力极强,在自然条件下的泥碳层中能存活千年,甚至在极端高温、高湿条件下仍能保持较高的萌发活力。随着莲基因组测序与基因注释的完善,莲子长寿机制的相关研究取得了一定进展。本文对莲子的结构形态、保护系统和基因组特性方面的研究进展进行了综述,阐明莲子的长寿机制,对后续研究方向进行了展望。

| Abstract: | Nelumbo nucifera Gaertn. belongs to the aquatic perennial herbs of Nelumbonaceae. The N. nucifera seeds exhibit strong vitality and can survive for more than a thousand years under natural and even extreme conditions. With the improvement of N. nucifera genome sequencing and gene annotation, some progress has been made in the study of the longevity mechanism of N. nucifera seeds. In this paper, the longevity mechanism is summarized from aspects of structure, morphology, anti-aging, and self-repair, and the prospects and challenges of follow-up research are discussed. |
