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;henceforth designated afb4-1) as a knockout allele.Complete loss-of-function of the AFB4gene confers defects in many aspects of the plant life cycle including lateral root development,hypocotyl elongation,leaf organogenesis,flowering time,seed formation,and disease resistance to specific phytopathogens.The results presented here argue against the previously proposed mechanism of AFB4 action in negatively controlling auxin sensitivity ”1”.
