The identification of these proteins reveals storage synthesis during the mature stage, especially since BiP proteins are extremely abundant throughout seed development. An unexpected error occurred. Nevertheless, soluble protein concentration increased continuously, reaching a maximum amount in the mature embryo Santa-Catarina et al.

Differencial protein expression among zygotic and apomitic seedlings of citrus

Running was set at Interestingly, certain proteins are frequently identified in proteomic studies eleteoforese to their abundance, such as enolases and ATP synthase beta subunits Petrak et al. Finally, these findings contribute to our understanding of protein expression dynamics during the development of recalcitrant seeds.

However, the genes identities, their products and mode of action were not elucidated yet.

The number, percentage volume criterion and distribution of spots were evaluated. Eletroforesr could be suggested that protein expression related to oxidative metabolism and the BiP proteins observed hereby appear as good makers in the final phase of development.

The present study permitted characterizing 2D protein profiles and identifying various proteins during seed development in O. The results allow for a better understanding of protein metabolism during developmental stages, as well as the establishment of possibly useful markers for improving and monitoring the development of both recalcitrant and orthodox somatic embryos, as many orthodox species present recalcitrant behavior when cultured in vitro Moon and Hildebrand ; Griga et al.

These findings contribute elertoforese a better understanding of protein metabolism during seed development in recalcitrant seeds, eletrofprese providing information on established markers that could be useful in defining and improving somatic embryogenesis protocols, besides monitoring the development of somatic embryos in this species.

Furthermore, the search is under way to trace biochemical and molecular markers in specific stages of embryogenesis in tree species Silveira et al. This method will be useful for in planta eletroforese bidimensional studies eletroforese bidimensional several phytopathogenic species. In the life cycle of higher plants, seed development is the key process connecting two distinct sporophytic generations Baud et al.

The class of protein exclusive to the zygotic profile is probably related to the expression of genes inherited from the male parental. De novo peptide sequencing via probabilistic network modeling. It has been demonstrated that proteomic analysis can generate relevant information towards elucidating the identity of those molecular mechanisms involved in developmental processes.
