Abstract

Seed longevity, which holds paramount importance for agriculture and biodiversity conservation, continues to represent a formidable frontier in plant biology research. While advances have been made in identifying regulatory elements, the precise mechanisms behind seed lifespan determination remain intricate and context-specific. This comprehensive review compiles extensive findings on seed longevity across plant species, focusing on the genetic and environmental underpinnings. Inter-species differences in seed lifespan are tied to genetic traits, with numerous Seed Longevity-Associated Genes (SLAGs) uncovered. These SLAGs encompass transcription factors and enzymes involved in stress responses, repair pathways, and hormone signaling. Environmental factors, particularly seed developmental conditions, significantly modulate seed longevity. Moreover, this review deliberates on the prospects of genetically engineering seed varieties with augmented longevity by precise manipulation of crucial genetic components, exemplifying the promising trajectory of seed science and its practical applications within agriculture and biodiversity preservation contexts. Collectively, our manuscript offers insights for improving seed performance and resilience in agriculture's evolving landscape.

揭示控制种子寿命的机制基础。

种子寿命对农业和生物多样性保护至关重要，它仍然是植物生物学研究的一个艰巨前沿领域。虽然在确定调控要素方面取得了进展，但种子寿命决定背后的精确机制仍然错综复杂，且因具体情况而异。本综述汇编了有关不同植物种子寿命的大量研究成果，重点关注其遗传和环境基础。种子寿命的种间差异与遗传特征有关，发现了许多种子寿命相关基因（SLAGs）。这些 SLAGs 包括转录因子和酶，涉及应激反应、修复途径和激素信号转导。环境因素，尤其是种子发育条件，对种子寿命有显著的调节作用。此外，这篇综述还探讨了通过精确操纵关键基因成分来培育长寿种子品种的前景，体现了种子科学的发展前景及其在农业和生物多样性保护领域的实际应用。总之，我们的手稿为在不断变化的农业环境中提高种子性能和抗逆性提供了真知灼见。
