我国农林生物安全视域下大豆共生固氮的分子设计育种
Molecular design breeding of soybean symbiotic nitrogen fixation from the perspective of agroforestry biosafety
摘要
Abstract
[Background]Under the global transition to green agriculture and agroforestry biosafety,research on soybean symbiotic nitrogen fixation(SNF)is shifting from fundamental mechanistic studies toward targeted molecular design breeding.[Progress]This review systematically summarize recent advances by domestic research teams across key dimensions symbiotic signaling,hormon,carbon-nitrogen coupling,environmental adaptation,immune homeostasis and senescence.Pecific topics encompass symbiotic factor perception and host-rhizobia compatibility multilayered auxin regulation of nodule organogenesis and light-nitrogen integration carbon allocation governed by energy sensors and light-signaling-driven nodulation high-nitrogen inhibition,salt stress responses and nitro-gen-toleran symbiosis-immune trade-off models and nodule senescence regulation.[Prospect]By compari international research para-digms,breakthrough directions and priority areas for Chinese soybean SNF research dual-benefit molecular design strategy that in-tegrates enhanced nitrogen fixation with disease resistance,specifically tailored for acidic red soils in southern China,thereby provi-ding a theoretical foundation for breeding novel soybean varieties with high yield,superior nitrogen fixation,and enhanced disease resistance.关键词
