CYCD4;1 is induced by Suc, and cycd4;1 mutants or wild-type
roots grown on low Suc have reduced lateral root density, associated
with an earlier transition of the pericycle cell file from the
apical to the basal meristem in which cell expansion initiates.
Since the basalmeristemcells are also larger, this leads to reduced
cell density in this region and fewer lateral root priming events
