Description: This experiment has been imported by PLEXdb from NCBI GEO (GSE9365)

Series_summary:
Plant seeds prepare for germination already during seed maturation. We performed a detailed transcriptome analysis of barley grain maturation, desiccation and germination in two tissue fractions (endosperm/aleurone = e/a and embryo = em) using the Affymetrix barley1 chip.
Keywords: time course

Series_overall_design:
Barley developing and germinating seeds were harvested at different time points after flowering (developing) and imbibition (germinating). To further disseect the influence of different tissues, seeds were dissecte and tissues were analyzed individually.


PLEXdb Curator's Note:
This experiment (Part 2 of 2) is a subset of GSE9365 that covers only the samples from the germinating grains. The original experiment in GEO is: "Expression data from barley maturing and germinating grains ".
Rest of the samples, from maturing grains, constitute another experiment (BB85, Part 1 of 2).

This has been done to accommodate the treatment-factors of this experiment into a factorial structure required in PLEXdb.
