Project description:Total RNA was isolated with TRIZOL reagent from wild-type flies (yellow white, yw) and Pumilio mutant flies (pum13; Barker DD. et al. (1992) Genes Dev 6, 2312-26). 12 microgram of total RNA was used for cDNA synthesis using a 1:1 mixture of oligo(dT) and random nonamer primers and in the presence of amino-allyl dUTP.

Project description:The quantitative proteomes of leaf tissue from A. thaliana at 4 weeks and 5 weeks of growth using tandem mass spectrometry with label-free quantification. A comparison of three genotypes has been performed, namely i) the Col-0 wild type ecotype, ii) a T-DNA insertion mutant disrupting the plastoglobule-localized ABC1K6 protein (abc1k6-1) that is delayed in transition to reproductive growth, and iii) a complementation line (Comp3) that restores the timely progression of development with the ABC1K6 wild-type protein sequence tagged C-terminally with GFP in the abc1k6-1 background. Whereas wild-type and abc1k6-1 remain in the vegetative growth stage at 4 weeks of age, the wild-type plants have transitioned to reproductive growth (as evidenced by the emergence of the infloresence bolt) by 5 weeks of age, while abc1k6-1 remians in vegetative growth. Our proteomics experiment seeks to identify leaf proteome differences prior to wild-type transition to reproductive growth that may account for the delayed transition in the abc1k6-1 mutant.
