Storage protein composition during germination and its association with physiological seed quality in common bean

Seed reserve mobilization is considered a post-germination process; however, seed storage protein occurs during germination. Thus, the knowledge of composition important to understand various processes germination, and it be associated with vigor. Therefore, this study aimed characterize landrace genotypes common bean (Phaseolus vulgaris) through fractionation proteins germination verify association between Genotypes highest (55 81) lowest (23 50) physiological quality were selected. Protein content analysis, profiling, characterization performed by combining different hydration times. Mass spectrometry involving in-gel digestion MALDI-ToF analysis was employed for qualitative identification proteins. Glutelin extraction detected enzyme lipoxygenase in 55 81 alone. In plants, may involved diverse processes, including growth development, pest resistance, senescence, response wounding. process removes reactive oxygen species mobilization; therefore, candidate biochemical marker high-vigor genotypes.
