The somatic embryogenesis transcriptome of Camellia oleifera
Camellia oleifera, a vital woody oil crop, faces challenges in genetic improvement efficiency due to its slow growth and difficulty in regeneration. This study focused on the expression levels of mRNA and miRNA during the somatic embryogenesis of C. oleifera, and the core genes of plant regeneration involved in the oil tea somatic embryogenesis process were identified, including DOF4.6, DOF5.6, WOX4, WOX8, and WOX13 during the somatic embryo callus induction phase, BBM, WOX11, PLT2, GRF, and GIF during the somatic embryogenesis and bud regeneration phase. The research data elucidates the process of somatic embryogenesis in C. oleifera at the molecular level. The key regulatory genes identified provide potential targets for improving the regeneration efficiency of C. oleifera and other woody oil-bearing plants.
