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.
