Effects of calreticulin on viral cell-to-cell movement.
Cell-to-cell tobacco mosaic virus movement protein (TMV MP) mediates viral spread between the host cells through plasmodesmata. Although several host factors have been shown to interact with TMV MP, none of them coresides with TMV MP within plasmodesmata. We used affinity purification to isolate a tobacco protein that binds TMV MP and identified it as calreticulin. The interaction between TMV M...
متن کاملCell-to-cell movement of plastids in plants.
Our objective was to test whether or not plastids and mitochondria, the two DNA-containing organelles, move between cells in plants. As our experimental approach, we grafted two different species of tobacco, Nicotiana tabacum and Nicotiana sylvestris. Grafting triggers formation of new cell-to-cell contacts, creating an opportunity to detect cell-to-cell organelle movement between the genetical...
متن کاملCell-to-cell movement of mitochondria in plants.
We report cell-to-cell movement of mitochondria through a graft junction. Mitochondrial movement was discovered in an experiment designed to select for chloroplast transfer from Nicotiana sylvestris into Nicotiana tabacum cells. The alloplasmic N. tabacum line we used carries Nicotiana undulata cytoplasmic genomes, and its flowers are male sterile due to the foreign mitochondrial genome. Thus, ...
متن کاملStatistical modelling of cell movement
Many important biological processes, such as wound healing, tissue development and cancer cell invasion, are based on the collective movement of cells. One of the main mechanisms for directed cell movement is chemotaxis, where cells follow chemical gradients (chemoattractants) present in their environment. These gradients might arise from the presence of a local source of chemoattractant or due...
متن کاملCompatibility of the movement protein and the coat protein of cucumoviruses is required for cell-to-cell movement.
For the cell-to-cell movement of cucumoviruses both the movement protein (MP) and the coat protein (CP) are required. These are not reversibly exchangeable between Cucumber mosaic virus (CMV) and Tomato aspermy virus (TAV). The MP of CMV is able to function with the TAV CP (chimera RT), but TAV MP is unable to promote the cell-to-cell movement in the presence of CMV CP (chimera TR). To gain fur...
