Transcriptome Analyses Reveal the Key Regulators of Tomato Compound Leaf Development

Leaves are one of the organs involved in plant assimilation and transpiration. Different leaf development processes can result different shapes. Tomato plants have typical compound leaves. It is helpful to explore regulatory factors affecting morphogenesis tomatoes cultivate varieties with high photosynthetic efficiency. We used tomato shape mutants Petroselinum (Pts), Trifoliate (tf2), Entire (e), which showed a gradual decrease leaflet number complexity. Transcriptome sequencing was performed analyze key differentially expressed genes (DEGs) among 3 groups, revealed 2393, 1366, 1147 DEGs Pts/VF36, tf2/CR, e/AC, respectively. found 86 overlapping groups. In addition, we that mutation Pts, tf2, e affected not only morphology but also wax, fatty acid, abscisic acid pathways during growth development. An RT-qPCR analysis primordium three transcription (bHLH079, WRKY44, WRKY76) hormone-regulated (IAA-amino hydrolase, Gibberellin2ox7, Gibberellin20ox) were transcriptome. Using virus-induced gene silencing (VIGS), observed VIGS bHLH079, IAA-amino Gibberellin20ox, WRKY76 endogenous regulators influencing This study provides promising direction for revealing molecular regulation mechanism underlying tomatoes.
