The Effect of Tomato C2H2 Greening Factor H on Gland Hair and Flower Color

Abstract

Abstract The Tomato H gene is responsible for encoding a C2H2 zinc finger protein, which is a critical transcription factor of the C2HC subfamily for the development of glandular trichomes. Through the analysis of zinc finger protein structure and subfamily, it is hypothesized that other genes similar to H may also have a regulatory role in the formation of epidermal hairs in Solanaceae plants. Functional validation of these genes has shown that when the H gene is overexpressed, there is a significant increase in the density of leaf trichomes, as well as a noticeable dwarf phenotype in the plants. The most notable effects are observed in floral organs, particularly in terms of flower morphology, corolla color, and differences in the morphology of epidermal cells.
