植物激素调控豆科植物根瘤发育的研究进展

Research Progress of Plant Hormones Regulating Nodule Development of Leguminous Plants

豆科植物与固氮微生物形成的共生固氮体系使植物可以利用大气中的氮元素,从而降低了植物对土壤中氮含量的需求。合理利用共生固氮可以减少农业生产中氮肥的施用量,对农业可持续发展具有重要意义。共生固氮体系的形成以及建立过程受多个信号的调控,其中植物激素是一类关键的影响因子,在共生固氮体系建立的整个过程中发挥着重要的作用。本文整理了植物激素对豆科植物根瘤形成和发育过程的影响,为后续的相关研究提供参考。

The symbiotic nitrogen fixation system formed by leguminous plants and nitrogen-fixing microorganisms enables plants to use nitrogen in the atmosphere, thus reducing the demand of plants for nitrogen content in the soil. Rational use of symbiotic nitrogen fixation can reduce the amount of nitrogen fertilizer used in agricultural production, which is of great significance to the sustainable development of agriculture. The formation and establishment of symbiotic nitrogen fixation system are regulated by multiple signals, among which plant hormones are a key influencing factor and play an important role in the whole process of symbiotic nitrogen fixation system establishment. In this paper, the effects of plant hormones on the formation and development of leguminous plant nodules were summarized, which provided reference for subsequent related research.
