The rhizoplast of chrysomonads, a basal body–nucleus connector that polarises the dividing spindle

An ultrastructure study of the rhizoplast in Synura petersenii, Mallomonas fastigiata, and M. insignis shows that it consists of 15–20 striated rootlets that form a claw or an incomplete cone over the nucleus. These rootlets course along one face of the nucleus between the nuclear membrane and the cis-face of the Golgi stack of cisternae. They converge and… CONTINUE READING
