Project description:We collected globular stage seed compartments from 5 or 7-micron paraffin sections using the Leica LMD6000 system in order to identify the mRNAs present in different compartments of an Arabidopsis seed containing a globular stage embryo. For the purposes of this study we broke down the seed into 7 capturable compartments: embyro proper, suspensor, micropylar endosperm, peripheral endosperm, chalazal endosperm, chalazal seed coat and general seed coat. Experiment Overall Design: Globular stage seed compartments were isolated using the LMD6000 system. Total RNA was amplified and hybridized with Affymetrix ATH1 Arabidopsis array for 15 samples (Embryo Proper, Micropylar Endosperm, Peripheral Endosperm, General Seed Coat and Chalazal Seed Coat, 2 biological replicates each and Chalazal Endosperm with 3 biological replicates).

For the purposes of this study we broke down the seed into 8 capturable compartments: embyro proper, suspensor, micropylar endosperm, peripheral endosperm, chalazal endosperm, chalazal seed coat, general seed coat, and whole seeds. Keywords: cell type comparison
Project description:We collected pre-globular stage seed compartments from 7-micron paraffin sections using the Leica LMD6000 system in order to identify the mRNAs present in different compartments of seeds containing pre-globular-stage embryos was identified as those seeds containing embryo propers made up of between 2 and 8 cells. For the purposes of this study we captured 6 compartments: embyro proper, micropylar endosperm, peripheral endosperm, chalazal endosperm, chalazal seed coat and general seed coat. Serial sections of entire seeds were also captured for comparison. Experiment Overall Design: Pre-globular stage seed compartments or whole seeds were isolated using the LMD6000 system. Total RNA was amplified and hybridized with Affymetrix ATH1 Arabidopsis array for 14 samples (embryo proper, micropylar endosperm, peripheral endosperm, chalazal endosperm, general seed coat, chalazal seed coat, whole seeds, 2 biological replicates each).
Project description:This SuperSeries is composed of the following subset Series:; GSE12402: Expression data from Arabidopsis seed compartments at the pre-globular stage. GSE12403: Expression data from Arabidopsis seed compartments at the linear-cotyledon stage. Experiment Overall Design: Refer to individual Series

Project description:SuperSeries contain expression data from the nuclei of cell types involved in patterning events, with focus on root apical stem cell formation, at 16-cell stage, early globular stage and late globular stage in the early Arabidopsis embryo (atlas). Expression data comparing nuclear and cellular RNA isolated from whole 16-cell stage Arabidopsis embryos is also included. This SuperSeries is composed of the SubSeries listed below.
