Network properties underlying seed germination control (2007)

Penfield, Steven, Fozard, John

We sought to gain a mechanistic understanding of the control of seed dormancy and germination by hormone balance. The field has matured to a stage where most of the key genes are known, and competing...

MYB61 Is Required for Mucilage Deposition and Extrusion in the Arabidopsis Seed Coat

Penfield, Steven, Meissner, Ruth C., Shoue, Douglas A., Carpita, Nicholas C., Bevan, Michael W.

We have undertaken a systematic reverse genetic approach to understand R2R3-MYB gene function in Arabidopsis. Here, we report the functional characterization of MYB61 based on the phenotype of three...

Reserve Mobilization in the Arabidopsis Endosperm Fuels Hypocotyl Elongation in the Dark, Is Independent of Abscisic Acid, and Requires PHOSPHOENOLPYRUVATE CARBOXYKINASE1

Penfield, Steven, Rylott, Elizabeth L., Gilday, Alison D., Graham, Stuart, Larson, Tony R., Graham, Ian A.

Arabidopsis thaliana is used as a model system to study triacylglycerol (TAG) accumulation and seed germination in oilseeds. Here, we consider the partitioning of these lipid reserves between embryo...

Arabidopsis ABA INSENSITIVE4 Regulates Lipid Mobilization in the Embryo and Reveals Repression of Seed Germination by the Endosperm[W]

Penfield, Steven, Li, Yi, Gilday, Alison D., Graham, Stuart, Graham, Ian A.

Regulation of seed germination requires coordinate action by the embryo and surrounding endosperm. We used Arabidopsis thaliana to establish the relative roles of embryo and endosperm in the control...
