doi:10.13560/j.cnki.biotech.bull.1985.2022-0095

Abstract

Abstract:

Carotenoids are a kind of important natural pigments widely distributed in nature，and they play an important role in the formation of plant ornamental quality. Carotenoid metabolic pathway controls the formation of plant colors such as yellow and orange，affects the synthesis of volatile aromatic compounds，and then affects the pigment deposition and aroma production of plant ornamental organs. In this paper，we review the molecular regulation of carotenoid metabolic pathways，the effects of carotenoid metabolic pathways on the color and aroma changes of plant flowers，fruits and leaves，and the improvement of carotenoids by genetic engineering technology，aiming to better understand the anabolic and regulatory mechanism of carotenoids in plant ornamental organs and to provide novel strategies for improving important ornamental traits of plants.

Key words: ornamental organs, carotenoid, metabolic regulation, color and fragrance, gene engineering technology
