Transcriptome analysis of marigold color

Marigold (Tagetes erecta L.) is an important ornamental plant with a wide variety of colors. Despite its economic value, there are few biochemical and molecular basic studies of flower color in marigold. To study the mechanism behind its color formation, metabolomics analysis and de novo cDNA sequencing was performed on marigold inbred line ‘V-01’ and its petal color mutant ‘V-01M’, in four flower developmental stages. The yellow variety 'V-01' and the orange variety 'V-01M' are divided into four stages for transcriptome sequencing.万寿菊（Tagetes erecta L.）是一类重要的观赏植物，花色丰富多样。尽管其具备较高经济价值，但目前针对万寿菊花色的生化与分子基础研究仍较为匮乏。为解析其花色形成的内在机制，研究团队以万寿菊自交系‘V-01’及其花瓣花色突变体‘V-01M’为实验材料，在四个花卉发育阶段开展了代谢组学分析与从头cDNA测序。黄色品种‘V-01’与橙色品种‘V-01M’均被划分为四个发育阶段以进行转录组测序。
