Soybean - second generation
The aim of this experiment was to identify differentially abundant proteins during soybean seed development in Chernobyl radioactive (RA) and non-radioactive (NRA) experimental fields. The soybean seeds were harvested at 4, 5, and 6 weeks after flowering (WAF) and in mature seeds (M) from both fields. Protein 2-DE gels from NRA and RA Chernobyl fields were analyzed separately using ImageMaster software 4.9. Gels of each developmental stage were matched individually to the reference gel in biological triplicate. A reference gel was obtained by analysis of pooled sample from all investigated stages of seed development. All matched spots were grouped into subclasses. Developmental profiles for a particular 2-DE spot were formed from spot subclasses across all developmental stages.
To ensure high quality of the datasets for comparative analysis, only 2-DE spot that satisfied the following criteria were included: 1) a 2-DE spot must be present in both datasets (i.e. from radioactive and non-radioactive field); 2) in each dataset, a 2-DE spot must be present in at least in two biological replicates and in at least three developmental stages. A total 211 2-DE spots satisfied these thresholds are circled on interactive 2-DE gel. The volumes of all spots that satisfied these criteria were normalized as relative volumes (%V) to compensate for small differences in sample loading or gels staining.
