Overexpression of housekeeping gene <i>FveIPT2</i> enhances anthocyanin and terpenoid accumulation in strawberry fruits with minimal impact on plant growth and development.

ABSTRACT: Anthocyanins and terpenoids are secondary metabolites with well-documented health benefits. Isopentenyl transferases (IPTs) are key enzymes in cytokinin (CK) biosynthesis. While ADP/ATP-type IPTs and their associated trans-zeatin (tZ)-CKs and iP-CKs are considered to play regulatory roles in growth and development, as well as stress acclimation in plants, tRNA-type IPTs and cis-zeatin CKs (cZ-CKs), which may serve housekeeping functions, remain less studied. In this study, the tRNA-type IPT gene FveIPT2 was overexpressed in woodland strawberries (Fragaria vesca). Overexpression had minimal impact on plant growth and CK levels but resulted in transgenic fruits exhibiting a significant increase in total phenolic, flavonoid, and anthocyanin contents,
