我国植物适应土壤逆境的分子机制研究主要进展

Advances in molecular mechanisms of plant adaptation to soil stress in China

  • 摘要: 土壤逆境泛指对植物生长和生存不利的各种土壤环境因素,如盐碱、酸性、淹水涝害等。植物在长期的进化过程中,对不同土壤逆境会产生一定的适应能力,了解植物对土壤逆境的生理反应和耐性分子机理,对发掘植物生长潜力,提高农业生产效率十分重要。我国植物营养生物学科研人员经过30多年的努力,在植物适应土壤逆境的分子机制研究领域,取得了一批国际领先的研究成果,如以STOP1为核心的植物抗铝调控机制;ALR1作为一个铝离子受体调控植物的抗铝性;根际铁在调控铵态氮耐性和氮素利用效率的分子机制;提升小麦耐盐性且不会影响穗发育的TaSPL6-D基因等。本文就近年来取得的部分土壤逆境的适应机制的进展(铝毒害、铁毒害和盐碱胁迫)进行简要评述。

     

    Abstract: Soil stress refers to the unfavorable environment to plant growth and survival, such as saline-alkali, acidic, waterlogging and so on. Plants have evolved a certain amount of mechanisms to adapt to soil stresses. Understanding the physiological response in molecular levels is important base for breeding and nutrient management in agricultural production. Through more than 30 years of efforts, a number of international leading research results have been carried out and some key breakthroughs were achieved by Chinese scholars, especially in such fields of plant nutrition biology like aluminum toxicity, iron toxicity and saline-alkali stress. The paper summarized the recent progress in the mentioned soil stress adaptation mechanisms in briefly. One of the mechanisms of plant resistance to aluminum is that the STOP1 as the core is formed. ALR1 has been identified as an aluminum receptor to regulate the aluminum resistance. The molecular mechanism of rhizosphere iron regulating ammonium-tolerance and nitrogen use efficiency was found. The TaSPL6-D gene, which can improve wheat salt tolerance and does not affect ear development, has been obtained.
