The RhMPK3-RhLOB41-RhWRKY9  mRNA sequence
Floral organ abscission is a genetically programmed process that is developmentally and environmentally regulated. The plant hormone ethylene and reactive oxygen species (ROS) are the main accelerators of floral organ abscission. However, the regulatory mechanisms underlying the accumulation of ROS during ethylene-induced flower abscission are still largely unknown.
