PCF4 — Solanum lycopersicum

Summary

SOLYC07G062680.3, also known as PCF4, TCP3, or SlTCP3, encodes a TCP family transcription factor on tomato chromosome 7. The product possesses DNA-binding transcription activator activity, sequence-specific DNA binding, and is associated with diverse molecular functions including histone binding, chromatin binding, and transcription coactivator activity. In tomato, this gene is linked to fruit shelf life, viroid response, and regulation of miRNA processing, as well as processes including fruit morphogenesis, inflorescence morphogenesis, lycopene anabolism, and specification of symmetry. It has been connected to numerous traits including fruit seed number, leaf flexibility, yield, plant male sterility, boron sensitivity, phenolic compound content, and UV-B light sensitivity. Studies of related genes in other species link the family to flavonoid accumulation, salt tolerance, seed oil content, and tuberization.
