Abstract: | A cell wall has been isolated from single-type cells, phloem fibers of flax (Linum usitatissimum L.) being at the stage of the active formation of a thick secondary cell wall. Weakly bound proteins of the cell wall of
phloem fibers were extracted and separated, and their mass spectra were recorded. The identification of the proteins and their
assignment to a particular cell compartment were performed using a variety of bioinformatics methods. In all, 93 proteins
were identified of which many proteins were defined as predicted, putative, and hypothetical. Twenty one proteins were identified
as cell-wall proteins. The absence of the marker proteins of primary cell walls such as xyloglucan endotransglycosylase and
expansins indirectly confirms the predominance of the secondary cell wall in a sample for protein extraction. |
