Transcript profile changes associated with lateral root fasciation in temperature-sensitive mutants

ABSTRACT: Control of the dimensions of organ primordia is crucial for proper organogenesis in the development of multicellular organisms. Lateral root formation is a major type of plant organogenesis important for postembryonic development of the root system. Lateral root formation begins with a few rounds of asymmetric, anticlinal cell division (formative cell division) in the pericycle, which determines the basal dimensions of root primordia. Here we show, based on molecular genetic analysis of temperature-dependent fasciation (TDF) mutants of Arabidopsis thaliana, that mitochondria play an unexpected role in the restriction of formative cell division and thus in the control of the basal dimensions of lateral root primordia. Three TDF mutants, root redifferentiation defective 1 (rrd1), rrd2, and r
