Abstract
This study identifies 3,4-dichlorophenylacetic acid (Dcaa) as a novel auxin analog that promotes plant growth through the auxin signaling pathway. Dcaa enhances oat coleoptile elongation, adventitious root generation, and root growth in various crops. Molecularly, it induces the expression of auxin-responsive genes and binds to auxin receptors, particularly TIR1. Dcaa also inhibits PIN protein endocytosis, a characteristic of auxins. These findings suggest Dcaa's potential for agricultural applications.
