H1 histones in higher plants have all the typical characteristics of this class of chromatin structural proteins , as well as in animals , are found in chromatin as nieallelicznych different variants. Due to a considerably simpler construction than in the animals and a smaller number of variants , plants, Arabidopsis thaliana , in particular , are extremely convenient universal model to study the mechanisms underlying the biological function H1 organisms in complex tissue . The results of previous work suggest that H1 in plants , in addition to the role in the modulation of transcriptional activity of genes and chromosomes architecture , may be the link to ensure coordination between the processes and transformations chromatin komórce.Wyniki microtubules recent global analysis on the DNA distribution of nucleosomes also show that the absence of the current in H1 animals pentapetydu GXGAX the key for interaction with DNA structural recital globular domain of plant H1 may be one of the causes greater developmental plasticity of plant cells .
