Expression data of wild-type and dcl1-15 torpedo-staged embryos

Project description:Severe loss-of-function alleles of DCL1 are embryonic lethal. Defects in cell division were seen as early as the globular stage in the strong loss-of-function allele dcl1-15. Phenotypic work with dcl1-15 and the null allele dcl1-5 suggested that, in addition to the severe patterning defects, the mutants were maturing earlier than wild-type embryos. We performed global gene expression analysis of dcl1-15 and wild-type torpedo staged embryos to examine this maturation phenotype further. The results suggested that DCL1 is a heterochronic gene. Comparisons to a time series of embryo development (http://www.seedgenenetwork.net/arabidopsis) showed that the genes differentially expressed in dcl1-15 embryos behaved more like green-cotyledon stage embryos than torpedo embryos.

[E-MTAB-366] Transcription profiling by array of chicken embryos at 15 different stages

Project description:Transcription profiling of chicken development The experiment were perfomed as a part of our Vertebrate Evo-Devo project. The aim of the project is to compare transcription profiles of normal (unmanipulated, wild-type, whole embryo) vertebrate embryos. Total RNA was collected from wild type G.gallus whole embryos at 15 different stages (Stages:HH1,2,4,6,8,9,11,14,16,19,24,27,32,34,38), and hybridized to the Affymetrix Chicken Genome Array. All the stages contains data from two biological replications. Each staged-samples consists of pooled total RNA from several whole embryos.

Gene expression in response to AGL15 during somatic embryogenesis

Project description:Transcript accumulation was measured using the Affymetrix Arabidopsis ATH1 Genome Array [ATH1-121501] to document changes in response to the MADS-domain transcription factor AGAMOUS-Like 15 during somatic embryogenesis. A somatic embryo system was used where mature seed is allowed to complete germination in liquid MS media containing 2,4-D and seedlings produce somatic embryos from the shoot apical meristem (SAM) region. The frequency with which these embryos are produced directly correlates with AGL15 accumulation. Experiment Overall Design: Wild type Arabidopsis (Columbia ecotype) with normal amounts of AGL15 were compared to (1) 35S:AGL15 that constitutively expresses AGL15 and produces more somatic embryos from the shoot apical region than wild type and (2) agl15 agl18 double loss-of-function mutants that produce less somatic embryos from the shoot apical region than wild type.

The aim of the project is to compare transcription profiles of normal (unmanipulated, wild-type, whole embryo) vertebrate embryos. Total RNA was collected from wild type C57BL/6 mice, whole embryos at 8 different stages (Stages:E7.5, E8.5, E9.5, E10.5, E12.5, E14.5, E16.5, E18.5), and hybridized to A-AFFY-45 Mouse Genome 430 2.0 Array. All the stages contains data from 2 to 3 biological replications. Each staged-samples consists of pooled total RNA from several whole embryos.
