TI  - Interphase chromosome arrangement in Arabidopsis thaliana is similar in 
      differentiated and meristematic tissues and shows a transient mirror symmetry 
      after nuclear division.

AB  - Whole-mount fluorescence in situ hybridization (FISH) was applied to Arabidopsis 
      thaliana seedlings to determine the three-dimensional (3D) interphase chromosome 
      territory (CT) arrangement and heterochromatin location within the positional 
      context of entire tissues or in particular cell types of morphologically 
      well-preserved seedlings. The interphase chromosome arrangement was found to be 
      similar between all inspected meristematic and differentiated root and shoot 
      cells, indicating a lack of a gross reorganization during differentiation. The 
      predominantly random CT arrangement (except for a more frequent association of 
      the homologous chromosomes bearing a nucleolus organizer) and the peripheric 
      location of centromeric heterochromatin were as previously observed for 
      flow-sorted nuclei, but centromeres tend to fuse more often in 
      nonendoreduplicating cells and NORs in differentiated cells. After mitosis, 
      sister nuclei revealed a symmetric arrangement of homologous CTs waning with the 
      progress of the cell cycle or in the course of differentiation. Thus, the 
      interphase chromosome arrangement in A. thaliana nuclei seems to be constrained 
      mainly by morphological features such as nuclear shape, presence or absence of a 
      nucleolus organizer on chromosomes, nucleolar volume, and/or endopolyploidy 
      level.
