Abstract:

Lignin,a pivotal constituent of plant cell walls,exerts a direct influence on the stress tolerance and quality attributes of fruit and vegetable crops through its synthesis and regulation. This paper presents a systematic review of lignin types,biosynthetic pathways,and regulatory mechanisms in fruit and vegetable crops. Studies have revealed that lignin accumulation is subject to the synergistic regulation of MYB/NAC transcription factors,miRNAs,and plant hormones,while also being significantly modulated by environmental cues such as temperature and light. Excessive lignin deposition leads to textural hardening in fruits and vegetables,whereas moderate accumulation facilitates wound healing and promotes ripening processes. Future research endeavors should prioritize the elucidation of the physiological,biochemical,and molecular mechanisms underlying lignin biosynthesis,expand the diversity of research subjects,and enhance the application potential of lignin in fruit and vegetable quality improvement and other agricultural contexts by manipulating lignin synthesis and metabolic pathways.

Key words: lignin, fruit and vegetable crops, regulatory mechanisms, quality, stress resistance
