摘要:

持绿性状在延缓植株衰老进程、提升有效光合效率及增加作物产量等方面具有重要作用;在增强作物抗逆性、减少化肥施用等方面具有可观的应用价值。为了深入了解作物持绿性状的优势及育种潜力,本文从持绿性状生理机制、分子调控网络、育种趋势3个层面系统综述了当前该性状的研究进展:在生理层面,阐述了该性状在作物生育后期通过稳定叶绿素含量、维持光系统活性、延长灌浆期及增加碳同化物质积累等途径提升作物产量;在分子调控网络互作层面,归纳了关键目标基因(如NAC、WRKY、GLK等转录因子)的定位与激素信号互作,共同调控衰老进程与持绿表型;在育种趋势层面,持绿已广泛用于多性状整合、氮素高效利用、抗旱耐逆等改良方向。当前研究仍存在QTL环境不稳定、持绿与养分再动员平衡机制不清、过度持绿影响品质等问题。提出未来应聚焦核心基因调控网络解析,平衡“延衰”与“营养转运”,培育高产、优质、抗逆、适宜机械化的持绿新品种。

Abstract:

The stay-green traits play an important role in delaying the aging of plants, improving effective photosynthetic efficiency and increasing crop yields; it has considerable application value in enhancing crop stress resistance and reducing fertilizer application. In order to gain a deeper understanding of the advantages and breeding potential of the stay-green trait in crops, this paper systematically reviews the current research progress on the stay-green trait from three aspects: physiological mechanism, molecular regulatory network, and breeding trend. At the physiological level, it explains that this trait stabilizes chlorophyll content, maintains photosystem activity, improves crop yields by extending the grouting period and increasing the accumulation of carbon-assimilating substances; at the level of molecular regulatory network interaction, summarized the localization and hormone signal crosstalk of key target genes (e.g., transcription factors including NAC, WRKY, and GLK), which co-regulate the senescence process and stay-green phenotype. At the breeding trend level, the stay-green trait has been widely adopted for improvements in multi-trait integration, high-efficiency nitrogen utilization, drought resistance and stress tolerance. At present, there are still some problems in the research, such as unstable QTL environment, unclear balance mechanism of stay-green and nutrient remobilization, and excessive stay-green affecting quality. In the future, we should focus on the analysis of core gene regulatory network, balance “delaying aging” and “nutritional remobilization”, and cultivate high-yield, high-quality, and suitable for mechanized production through multi-trait collaborative improvement.

Key words: stay-green trait, yield enhancement, enhanced stress resistance, breeding trends, multi-trait integration breeding
