This process involves eight protein elements including SLG, SCR, SRK, MLPK, THL, ARC1, Exo70A1, and MIP-MOD. Here, based on their corresponding gene’s architecture, we summa- rized these elements on their advances both in structure and function of their genes and proteins, as well as their interaction along the whole SI signal transduction process. Furthermore, we put forward some insights into unknown areas of SI, hoping to provide a few of clues for further exploration of SI mechanism in B. oleracea or other Brassica species.
