Phytoplasmas are bacterial plant pathogens which can induce severe symptoms including dwarfism, phyllody and virescence in the infected plant. Because phytoplasmas infect many important crops such as peanut and papaya, they have caused serious agricultural losses. The phytoplasmal effector causing phyllody 1 (PHYL1) is an important pathogenic factor of phytoplasma. PHYL1 affects the biological function of MADS transcription factors by interacting with their K (keratin-like) domain, and thus results in abnormal plant developments such as phyllody. Until now, the lack of PHYL1 structural information has prevented detailed understanding of the binding mechanism between PHYL1 and the MADS transcription factors. Here, we present the crystal structure of PHYL1 from Peanut witches'-broom phytoplasma. PHYL1Pn WB folds into a unique alpha-helical hairpin with exposed hydrophobic residues on its surface that may play an important role in its biological function. Using proteomic approaches, we propose a binding mode of PHYL1Pn WB with the K domain of SEPALLATA3 MADS transcription factor (SEP3_K) and identify the important residues of PHYL1Pn WB for this interaction. Furthermore, by using surface plasmon resonance (SPR), we measure the binding strength of PHYL1Pn WB proteins to SEP3_K. Lastly, based on confocal images, we found that the alpha -Helix 2 of PHYL1Pn WB plays an important role in PHYL1-mediated SEP3 degradation. Taken together, these results provide a structural understanding of the specific binding mechanism between PHYL1Pn WB and SEP3_K. This article is protected by copyright. All rights reserved.
