Figure 6

The distribution of microsatellite sequences in fractions obtained in the course of chromatography of nucleoproteins on celite. A. The distribution of DNA fragments containing given microsatellites in unbound to nuclear matrix fraction (eluted in NaCl gradient, DNA 0, column 0 on the Figure), loosely bound to the nuclear matrix (eluted in LiCl-urea gradient and in temperature gradient below 70°C, DNA I (column I) and tightly bound to the nuclear matrix (eluted in temperature gradient at 90°C, DNA II, column II). Grey and white squares indicate presence and absence of amplification correspondingly. All other designations are like in Figure 4. B. Summary of the trends of transitions during development of different organs compared with the situation in dry seed. Grey squares – situation in the seed or similar; white squares – loosening of association with the nuclear matrix; black squares -tightening of interactions. C. General summary of involvement of the studied genomic sites in association-dissociation according the NPC chromatography data. Black points on white background – sites involved in transitions; white points on black background – sites not involved in transitions.
