ARID (AT-Rich Interacting Domain) proteins in animals are involved in cell cycle regulation.Although the ARID domain is conserved and widely present in plants, the function of plant ARID proteins has been largely unexplored.The role of ARID proteins in sperm cell formation in plants is particularly intriguing given that mature pollen is composed of a vegetative cell and two sperm cells which are established by two consecutive mitoses.
