番茄SlDSP基因调控萼片形态影响果实品质
Tomato SlDSP Gene Regulates Sepal Morphology Affecting Fruit Quality
摘要
Abstract
The tomato SlDSP gene is involved in the regulation of sepal morphology.To investigate the relationship between tomato calyx morphology and fruit quality composition,wild-type tomato TI1101 with naturally mutated dsp calyx base and upright calyx blackberry tomato(WT)with overexpressed SlDSP gene calyx base plants were used as materials.The main flavor quality,nutritional quality,and commercial quality of mature fruits were compared and analyzed.The results showed that mutations or overexpression of the SlDSP gene led to different calyx shapes in tomatoes,which in turn affected the total sugar content,glucose content,fructose content,sugar-to-acid ratio,lycopene content,vitamin C content,soluble solids content,and calyx depression size.These traits were significantly higher in the encapsulated calyx tomato than in the basal calyx tomato,and the basal calyx tomato was significantly higher than the erect calyx tomato.Total acid content,citric acid content,and malic acid content were significantly higher in erect calyx tomatoes than in basal calyx tomatoes,and basal calyx tomatoes were significantly higher than in enveloped calyx tomatoes.Single fruit weight and fruit firmness were significantly higher in enveloped and erect calyx tomatoes than in basal flat calyx tomatoes.This indicates that tomato calyx morphology not only affects fruit appearance quality but also plays an important role in fruit nutritional quality and taste.Regulation of calyx morphology by the SlDSP gene is an effective approach to improving fruit quality.关键词
