摘要

摘要: 海草床在保护海洋生物多样性、缓解海水酸化、防止土壤侵蚀等方面发挥着关键作用。但是，全球气候变化以及人类活动严重影响海草的生存，造成海草大面积退化，威胁近岸海域生态系统安全。近年来，微生物促进海草床能量流动和海草生长发育的作用逐渐受到重视，植物促生微生物（Plant Growth-Promoting Microorganisms，PGPM）有望应用于海草苗种培育、植株移植、种子种植等海草床修复的关键技术中。本文综述了国内外关于微生物与海草相互作用促进植株生长和抵御环境胁迫的研究情况，总结了PGPM在高温、高盐、弱光等环境条件下增强植物胁迫耐受性的作用机制，提出利用现代分子生物学技术筛选海草促生微生物，明确其定植部位，探究不同环境条件下PGPM与海草相互作用的分子机制，为植物促生微生物PGPM应用于海草床修复及海草保护提供参考。

Abstract: Seagrass meadows play a vital role in protecting marine biodiversity, mitigating ocean acidification, and preventing soil erosion in the coastal ecosystem. However, global climate change and human activities seriously affect the life of seagrass, which causes the widespread degradation of the seagrass and threatens the safety of coastal ecosystems. Recently, the vital value of microorganisms in promoting the energy flow of seagrass meadows and their growth and development has gradually gained attention. Plant Growth-Promoting microorganisms(PGPM) will play their value in seedling cultivation, plant transplantation, seed planting, and other techniques of seagrass meadow restoration. This paper reviewed the research on how seagrass interacts with microorganisms to promote the growth of plants and increase the resistance to abiotic stress. We introduced the mechanism of PGPM to enhance plant stress tolerance under high temperature, high salt, and low light. The proposed use of modern molecular biology technology to screen seagrass PGPM, clarify the colonization site of PGPM, and explore the molecular interaction mechanism between PGPM and seagrass under different environmental conditions. To provide a reference for promoting the application of PGPM in seagrass meadow restoration and seagrass protection.
