F-box protein AFB4 plays a crucial role in plant growth, development and innate immunity

Dear Editor, Auxin-signaling F-box protein 4 （AFB4） encoded by At4g24390 shares a significant sequence similarity to auxin receptor TIR1. In this study, we used a combination of physiological, molecular, and genetic approaches to characterize a T-DNA insertion line （GABI-KAT accession no.： 068E01; h...

Description
Summary:	Dear Editor, Auxin-signaling F-box protein 4 （AFB4） encoded by At4g24390 shares a significant sequence similarity to auxin receptor TIR1. In this study, we used a combination of physiological, molecular, and genetic approaches to characterize a T-DNA insertion line （GABI-KAT accession no.： 068E01; henceforth designated afb4-1） as a knockout allele. Complete loss-of-function of the AFB4 gene confers defects in many aspects of the plant life cycle including lateral root develooment,
