  abstract = {{L}ateral root organogenesis plays an essential role in elaborating plant root system architecture. {I}n {A}rabidopsis, the {AP}2 family transcription factor {PUCHI} controls cell proliferation in lateral root primordia. {T}o identify potential targets of {PUCHI}, we analyzed a time course transcriptomic dataset of lateral root formation. {W}e report that multiple genes coding for very long chain fatty acid ({VLCFA}) biosynthesis enzymes are induced during lateral root development in a {PUCHI}-dependent manner. {S}ignificantly, several mutants perturbed in {VLCFA} biosynthesis show similar lateral root developmental defects as puchi-1. {M}oreover, puchi-1 roots display the same disorganized callus formation phenotype as {VLCFA} biosynthesis-deficient mutants when grown on auxin-rich callus-inducing medium. {L}ipidomic profiling of puchi-1 roots revealed reduced {VLCFA} content compared with {WT}. {W}e conclude that {PUCHI}-regulated {VLCFA} biosynthesis is part of a pathway controlling cell proliferation during lateral root and callus formation.},
