| Zusammenfassung: | Copyright © 2023 Elsevier Masson SAS. All rights reserved. Moso bamboo winter shoot has good taste and rich nutritional value. To reveal the causes and regulatory mechanism of palatability deterioration from winter to spring shoot, a conjoint analysis of metabolome and transcriptome was conducted on winter and spring shoots of moso bamboo. Totally 909 metabolites were characterized for the first time. The significant increase of hydrolyzed tannin content intensified the bitterness of spring shoot, which was positively regulated by key metabolite (gallic acid) and genes (DAHPS, DHQS, DHQ, SDH) in the biosynthesis pathway of hydrolyzed tannin. The accumulation of lignified components enhanced the roughness of spring shoot, which was closely connected with the significant changes of important metabolites (cinnamic acid, ferulic acid, UDP-glucose and UDP-xylose) and up-regulation of most enzyme genes involved in the biosynthesis pathways of lignin, cellulose and hemicellulose. The present study provides theoretical support for understanding palatability transition and directional improvement of edible quality of moso bamboo shoots |
