RACK1 has Been proved to regulate plant hormone signaling, stress responses and multiple processes during plant growth and development. It is a scaffold protein that acts downstream of and is phosphorylated By WNK8 in the glucose responsiveness and flowering pathways. In AraBidopsis, a total of three RACK proteins were found: At1g18080 (RACK1A) , At1g48630 (RACK1B) and At3g18130 (RACK1C) .
