Updated project metadata. The associated files are mass spec data from individual fractions of mixed-bed ion exchange chromatography of native extract made from Arabidopsis thaliana (mutant ttg1-1, Koornneef (1981) Arabid. Inf. Serv. 18,45-51.) seeds. This is a hypomorph of the Transparent Testa Glabra 1 gene and was used instead of wild type because it is mucilage-less, facilitating protein extract preparation.
