摘要： Increasing the level of AsA and maintaining proper lignin content will improve the quality of celery (Apium graveolens L.). However, the study on the regulation mechanism of genes related to AsA and lignin metabolism in celery was limited, especially in yellow celery. In this study, the accumulation of AsA and lignin and the expression profiles of related-genes were detected in three kinds of yellow celery. The results showed that the content of AsA was higher in the leaf blades of 'Huangtaiji' and the petioles of 'Jinhuangqincai'. The content of lignin was the highest in 'Jinhuangqincai' leaves, followed by 'Liuhehuangxinqin' and 'Huangtaiji'. The expression levels ofAgAO(r= -0.032) andAgDHAR1(r= -0.193) genes involved in AsA recycling and degradation showed negatively correlated with AsA content.AgCCoAOMT(r= 0.692) andAgF5 H(r= 0.733) genes expression were positively correlated with lignin content, while the expression ofAgCAD(r= -0.694) andAgC3MODIFIER LETTER PRIMEH(r= -0.722) genes were negatively correlated with lignin content. Our current work provided potential theoretical basis for effectively changing accumulation of AsA and lignin by genetic engineering in celery.
