Abstract
The transcription factor LEAFY COTYLEDON1 (LEC1) controls aspects of early embryogenesis and seed maturation in Arabidopsis thaliana. To identify components of the LEC1 regulon, transgenic plants were derived in which LEC1 expression was inducible by dexamethasone treatment. The cotyledon-like leaves and the swollen root tips developed by these plants contained seed storage compounds and resembled the phenotypes produced by the increased auxin levels. Accordingly, LEC1 mediated the up-regulation of the auxin synthesis gene YUCCA10. Auxin was accumulated primarily in the elongation zone at the root-hypocotyl junction (collet). This accumulation correlates with hypocotyl growth which is either inhibited or stimulated in the LEC1-induced long-hypocotyl phenotype resembling etiolated seedlings. Chromatin immuno-precipitation analysis revealed a number of phytohormone- and elongation-related genes among the putative LEC1 target genes. LEC1 seems to be an integrator of different regulatory events, involving the transcription factor itself as well as light and hormone signaling, especially during somatic and early zygotic embryogenesis. Furthermore the data allow speculations about non-embryonic functions for LEC1 during post-germinative etiolation. © 2012 The Authors. The Plant Journal © 2012 Blackwell Publishing Ltd.
