Transcription profiling of Arabidopsis early post-germinative embryo and endosperm

ABSTRACT: Arabidopsis seed germination is coordinated with the strong induction of metabolic pathways required for the mobilisation and utilization of seed storage reserves. These are essential to support the seedling before the establishment of photoauxotrophic growth. The activity of genes encoding enzymes required for lipid mobilisation is regulated largely at the level of transcription, but our knowledge of how this regulation occurs is extremely limited. After germination the rate of lipid reserve mobilisation is determined by the carbohydrate status of the seedling and by the osmotic potential of the growth substrate. The plant response to both of these requires the action of the hormone abscisic acid (ABA). We have shown that this regulation is tissue specific (Penfield et al., 2004 Plant Cel
