Özet
This research delves into phenylpropanoid metabolism, focusing on phenylpropene biosynthesis in the methyleugenol chemotype of basil (Ocimum basilicum L.). We isolated peltate glandular trichomes (PGTs) from basil leaves to eliminate primary metabolic influences, offering a unique perspective into these complex processes. Vermicompost, chosen for its eco-friendly composition and superiority in invigorating phenylpropanoid metabolism. In this study, we investigated the impacts of solid and tea-form vermicompost applications at 0%, 10%, and 25% doses on the methyleugenol chemotype of basil, focusing on the expression levels of PAL, 4CL, EGS, EOMT, and CVOMT genes and phenylpropene accumulation in the peltate glandular trichomes. Results showed that 10% solid vermicompost (SV) application increased 4CL expression level at 236%, while 25% SV application further enhanced EOMT and CVOMT expressions to towering values by 7,494-fold and 19,643-fold, respectively. SV applications did not significantly impact eugenol accumulation but suppressed chavicol biosynthesis. Methyleugenol and methylchavicol accumulation rose in a dose-dependent manner, with significant increases observed in the 25% SV application. A positive correlation was found between CVOMT expression and accumulation rates of methyleugenol and methylchavicol phenylpropenes following SV applications. Conversely, vermicompost tea (VT) applications led to mixed gene expression patterns and reduced eugenol and methyleugenol ratios in peltate glandular trichomes compared to control. In summary, the notably high gene expressions observed in the results of our preliminary study offer a new perspective in the field of phenylpropanoid metabolism. This underscores the value of utilizing single-cell type PGTs for examining secondary metabolic pathways in plants and demonstrates the impact of vermicompost on phenylpropene production.
