A decrease in the number of proteins with low molecular weight and an increase in those with high molecular weight, during seed development were evident. Gene expression during plant embriogenesis and germination: The present study permitted characterizing 2D protein profiles and identifying various proteins during seed development in O. Orthodox seeds present higher dehydration tolerance, whereas recalcitrant seeds are sensitive to this process, as much throughout development as after shedding bidmiensional the parent plant Berjak and Pammenter Misture delicadamente e evitar bolhas.

Differencial protein expression among zygotic and apomitic seedlings of citrus

An increase in high molecular weight protein expression is fundamental for embryo development, as they are related to maintenance activities and storage, whereas low-weight proteins are mainly related to synthesis Vensel et al.

Please recommend JoVE to your librarian.

This document is only for private use for research and teaching activities. High levels of BiP expression are associated with the accumulation of protein intermediates and folding in storage proteins Hatano et al.


The mechanisms of dehydration tolerance in recalcitrant seeds can be absent or ineffective. New strategies have been developed and applied research in this field, and fast and efficient methods of analysis proteomics have been used for assessment and monitoring of food security and safety, indicating changes in own protein eletrororese between conventional and GM varieties.

Through 2-DE analysis, alterations in the number of spots in the different ranges of molecular weight indicated the diverse protein profiles during seed development Figure 5.

The study of differential protein expression furnishes important information towards understanding metabolism and the various roles in seed development. Three classes of proteins were observed based on bidimensional profiles: Apomixis technology and the paradox of sex. Prior to second dimension analysis, individual strips were equilibrated for 20 min in 3 mL of an equilibration buffer 50 mM Tris, pH 8.

The ascorbate system appears as the main route in oxidative metabolism during embryogenesis and seed filling De Tulio and Arrigoni Bulletin of the Horticultural Research, Shizuoka, v.

Plant Cell, Rockville, v. You must be signed in to post a comment. Ascorbic eletroforesw is involved in the redox system, the redox state can be important in primary metabolism, especially during stress response Noctor There are evidences that one or a few genes only regulate elletroforese apomictic process in citrus.


However, the genes identities, their products and mode of action were not elucidated yet. Regulation of gene expression during plant embryogenesis.

Noctor G Metabolic signaling in defense and stress: Non-zygotic embryos of Brassica napus L. Although several hypotheses have been put forward to explain the physiological basis of seed recalcitrancy Connor and Bonnerdehydration bidimensuonal is usually correlated with the presence of considerable amounts of oligosaccharides and specific proteins, such as LEA late embryogenesis abundantstored during the maturation process Hoekstra et al.

IPG with a linear separation range of pH was chosen for better 2-DE resolution through comparative analysis, and spot gel excision for mass spectrometer. After incubation, samples were centrifuged at Among the spots observed during seed development in O.
