TranscriptomicsExtensive imprinted gene expression in Arabidopsis endosperm
Some flowering plant and vertebrate genes are expressed primarily or exclusively from either the maternal or paternal allele, a phenomenon called genomic imprinting. Flowering plant imprinted gene expression has been described primarily in endosperm, a terminal nutritive tissue consumed by the embry...

TranscriptomicsThe naked endosperm genes encode duplicate ID domain transcription factors required for maize endosperm differentiation
The objective of the current study is to unravel the gene regulatory networks controlled by the nkd genes during maize endosperm development. We compared wild type (B73) vs. nkd mutant (introgressed into B73 background) transcriptomes in aleurone vs. starchy endosperm cell types captured by laser ca...

TranscriptomicsProbing the endosperm gene expression landscape in Brassica napus
In species with exalbuminous seeds such as crucifer oilseeds and legumes, the endosperm is eventually consumed and its space occupied by the embryo during seed development. However, the main constituent of the early developing seed is the liquid endosperm, and most of the carbon resources for the en...

ProteomicsAnalysis of the protein distribution within the wheat endosperm
Starchy endosperm proteins determine wheat quality and exhibit, besides a quantitative protein gradient, a qualitative protein gradient from the outer to inner starchy endosperm. The goal was to investigate the relative differences in protein composition between the aleurone, sub-aleurone and inner ...

ProteomicsProteome Dynamics of the Cotyledonary Haustorium and Endosperm in the Course of Germination of Euterpe oleracea Seeds
The role of the cotyledonary haustorium (CH) in the mobilization of nutrient reserves in the endosperm of species of the palm family Arecaceae is a moot question. To shed light on this matter, we present here an analysis of the quantitative proteome changes associated with four developmental stages ...

GenomicsGenome-wide demethylation of Arabidopsis endosperm
Parent-of-origin-specific (imprinted) gene expression is regulated in Arabidopsis thaliana endosperm by cytosine demethylation of the maternal genome mediated by the DNA glycosylase DEMETER, but the extent of the methylation changes is not known.  Here we show that virtually the entire endosperm gen...

TranscriptomicsMaternal siRNAs as regulators of parental genome imbalance and gene expression in endosperm of Arabidopsis seeds.
Seed size is important to crop domestication and natural selection and is affected by the balance of maternal and paternal genomes in endosperm. Endosperm, like placenta in mammals, provides reserves to the developing embryo. Interploidy crosses disrupt the genome balance in endosperm and alter seed...

TranscriptomicsTranscription profiling of the radicle and micropylar endosperm cap of Lepidium seeds during germination in control medium
An experiment was performed to compare global transcription patterns in three tissues of Lepidium sativum seeds at different times during imbibition leading up to, but not including, radicle protrusion from the seed (e.g. germination). RNA extractions from the three tissues were hybridised to CATMA ...

TranscriptomicsExpression data from early rice endosperm
We used microarrays to detail the global programme of gene expression underlying cellularization and identified distinct classes of regulated genes during this process. Rice endosperm at 2 days after pollination(DAP) was selected for RNA extraction and hybridization on Affymetrix microarrays. We sou...

ProteomicsThe Arabidopsis mature endosperm promotes seedling cuticle formation via release of sulfated peptides
In Arabidopsis mature seeds, the onset of the embryo-to-seedling transition is nonautonomously controlled, being blocked by endospermic abscisic acid (ABA) release under unfavorable conditions. Mature embryos lack an impermeable cuticle, unlike seedlings, consistent with their endospermic ABA uptake...
