RosaDamascenaMill.,通常被称为国王花,是玫瑰科的芳香和重要物种。它广泛用于香水和制药行业。花的香味和颜色是这种观赏植物的重要特征。本研究旨在探讨MYB1、CCD1、FLS、PAL,CER1,GT1,ANS和PAR基因在两个生长阶段(S1和S2)处于两个形态。CCD1基因通路与挥发性化合物的生物合成高度相关。结果表明,香气和颜色产生中的重要转录因子MYB1的过表达,在样品S2的热粉红色变体中,PAR的表达增加,PAL,FLS,RhGT1,CCD1,ANS,CER1和GGPPS。茉莉酸甲酯(MeJA)兴奋剂对大多数基因的基因表达有积极和累积的影响,例如S2样本的ACC.26中的FLS,RhGT1,MYB1,CCD1,PAR,ANS,CER1和PAL在ACC.1.为了进一步研究,进行了综合分析,以评估主要挥发性化合物与颜色之间的关系。我们的数据表明,粉红色花朵的玫瑰具有较高的类黄酮和花色苷积累含量。为了分离精油化合物,GC/MS分析鉴定了四个样品中的26个化合物。香叶醇含量最高,锦缎玫瑰的主要成分之一,被发现在热粉红色的花朵上,23.54%,在MeJA激素的影响下。
Rosa damascena Mill., commonly known as the King Flower, is a fragrant and important species of the Rosaceae family. It is widely used in the perfumery and pharmaceutical industries. The scent and
color of the flowers are significant characteristics of this ornamental plant. This study aimed to investigate the relative expression of MYB1, CCD1, FLS, PAL, CER1, GT1, ANS and PAR genes under two growth stages (S1 and S2) in two morphs. The CCD1 gene pathway is highly correlated with the biosynthesis of volatile compounds. The results showed that the overexpression of MYB1, one of the important transcription factors in the production of fragrance and
color, in the Hot pink morph of sample S2 increased the expression of PAR, PAL, FLS, RhGT1, CCD1, ANS, CER1, and GGPPS. The methyl jasmonate (MeJA) stimulant had a positive and cumulative effect on gene expression in most genes, such as FLS in ACC.26 of the S2 sample, RhGT1, MYB1, CCD1, PAR, ANS, CER1, and PAL in ACC.1. To further study, a comprehensive analysis was performed to evaluate the relationship between the principal volatile compounds and colors. Our data suggest that the rose with pink flowers had a higher accumulation content of flavonoids and anthocyanin. To separate essential oil compounds, GC/MS analysis identified 26 compounds in four samples. The highest amount of geraniol, one of the main components of damask rose, was found in the Hot pink flower, 23.54%, under the influence of the MeJA hormone.
