Impact of melatonin application on lignification in water bamboo shoot during storage.

ABSTRACT: Melatonin, a crucial bioactive molecule, involved in several physiological processes in plants. This study investigated the effects of melatonin (MT) treatment on lignification, including firmness, lignin, lignified-enzyme activities, the expression patterns of genes encoding corresponding enzymes and transcription factors in water bamboo shoot during storage for 8 days. MT treatment decreased the firmness and content of lignin. It inhibited the degradation of total phenols and ascorbic acid and delayed the lignin biosynthesis, via reducing the activities of phenylalanine ammonia-lyse cinnamyl alcohol dehydrogenase and peroxidase, as well as lignin biosynthesis-related genes expression levels. Transcription factors of ZlNAC1, ZlNAC2, ZlNAC3 and ZlNAC4 from NAC family and Z
