The () gene encodes the florigen protein, which primarily regulates the flowering time in plants. Recent studies have shown that genes also significantly affect plant growth and development. The gene overexpression in plants promotes flowering and suppresses leaf and stem development. This study aimed to conduct a transcriptome analysis to investigate the multiple effects of L. homolog () overexpression on leaf growth in tobacco plants. The findings revealed that overexpression affected various biological processes during leaf development, including plant hormone levels and signal transduction, lipid oxidation metabolism, terpenoid metabolism, and the jasmonic-acid-mediated signaling pathway. These results suggested that the effects of overexpression in plants were complex and multifaceted, and the combination of these factors might contribute to a reduction in the leaf size. This study comprehensively analyzed the effects of on leaf development at the transcriptome level and provided new insights into the function of and its homologous genes.
