The virtual seed (vSEED): Combined mathematical, engineering and post-genomics comparative biology to model the systems biology of seed dormancy, after-ripening and germination.
Zusammenfassung der Projektergebnisse
Major outputs of the vseed project were: 1. Development of on-line computational model of seed germination and associated resources (vseed.nottingham.ac.uk); publically available high-resolution transcriptome datasets: GEO reference GSE41212. 2. The first systems biology approach to the analysis of seed germination, including mathematical modelling of endosperm rupture, cross-species transcriptome and qRT-PCR analyses of major seed compartments, and computational modelling of gene interactions. 3. State-of-the-science analysis of cell walls in Arabidopsis, Lepidium and tobacco seeds indicating the novel aspects of endosperm cell wall molecular architectures including that there is no heteromannan in Arabidopsis/Lepidium cell walls and no detectable tissue-level asymmetry. Tobacco became an important comparative species and this was not envisaged in the original application. Cell wall analysis linked to seed biomechanics on different length scales to analyse dynamic seed material properties.
