“…Specifically, Arabidopsis chromatin contains H3K4/H3K36 and H3K9/H3K27 methylation marks indexing active and inactive chromatin, respectively. [26][27][28][29][30][31] Also, histone acetylation in plants has been characterized, 32,33 and the family of plant HDAC proteins includes, based on sequence analysis of the Arabidopsis genome, three major groups: PD3/HDA1 and SIR2 conserved in eukaryotes and a plant-specific HD2 family. 34 Recently, we have isolated two main components of a novel chromatin-modifying corepressor complex from Arabidopsis thaliana: -a SWIRM-domain PAO-like (SWP) protein AtSWP1, and a plantspecific C2H2 zinc finger PreSET-SET-PostSET-domain (CZS) protein AtCZS that likely acts as HMT (Fig.…”

“…However, sequencing of the Arabidopsis thaliana and rice genomes has identiWed genes encoding homologues of Snf2 ATPase, SNF5 and SWI3 subunits of SWI/SNF complexes (Brzeski et al 1999;Verbsky and Richards 2001;Sarnowski et al 2002;Wagner and Meyerowitz 2002;Farrona et al 2004;Jerzmanowski 2007;Kwon and Wagner 2007; see also the Plant Chromatin Database at http://chromdb.org). Of the four potential Arabidopsis orthologues of the Snf2-type ATPase, only BRA-HMA (BRM) carries a bromodomain.…”

In yeast and mammals, ATP-dependent chromatin remodelling complexes of the SWI/SNF family play critical roles in the regulation of transcription, cell proliferation, diVerentiation and development. Homologues of conserved subunits of SWI/SNF-type complexes, including Snf2-type ATPases and SWI3-type proteins, participate in analogous processes in Arabidopsis. Recent studies indicate a remarkable similarity between phenotypic eVects of mutations in the SWI3 homologue ATSWI3C and bromodomain-ATPase BRM genes. To verify the extent of functional similarity between BRM and ATSWI3C, we have constructed atswi3c brm double mutants and compared their phenotypic traits to those of simultaneously grown single atswi3c and brm mutants. In addition to inheritance of characteristic developmental abnormalities shared by atswi3c and brm mutants, some additive brm-speciWc traits were also observed in the atswi3c brm double mutants. Unlike atswi3c, the brm mutation results in the enhancement of abnormal carpel development and pollen abortion leading to complete male sterility. Despite the overall similarity of brm and atswi3c phenotypes, a critical requirement for BRM in the diVerentiation of reproductive organs suggests that its regulatory functions do not entirely overlap those of ATSWI3C. The detection of two diVerent transcript isoforms indicates that BRM is regulated by alternative splicing that creates an in-frame premature translation stop codon in its SNF2-like ATPase coding domain. The analysis of Arabidopsis mutants in nonsense-mediated decay suggests an involvement of this pathway in the control of alternative BRM transcript level.

“…During the past decade, however, an increasing number of reports has emphasized the roles of histone modification and histone variants in the regulation of gene expression (Paull et al, 2000;Rice and Allis, 2001;Verbsky and Richards, 2001;Ausio and Abbott, 2002;Fransz and de Jong, 2002;Redon et al, 2002). Histone acetylation and methylation in particular have been implicated in gene expression (Vongs et al, 1993;Hirochika et al, 2000;Beisel et al, 2002;Volpe et al, 2002).…”

Constitutive Expression Exposes Functional Redundancy between the Arabidopsis Histone H2A Gene HTA1 and Other H2A Gene Family Members

The Arabidopsis thaliana histone H2A gene HTA1 is essential for efficient transformation of Arabidopsis roots by Agrobacterium tumefaciens. Disruption of this gene in the rat5 mutant results in decreased transformation. In Arabidopsis, histone H2A proteins are encoded by a 13-member gene family. RNA encoded by these genes accumulates to differing levels in roots and whole plants; HTA1 transcripts accumulate to levels up to 1000-fold lower than do transcripts of other HTA genes. We examined the extent to which other HTA genes or cDNAs could compensate for loss of HTA1 activity when overexpressed in rat5 mutant plants. Overexpression of all tested HTA cDNAs restored transformation competence to the rat5 mutant. However, only the HTA1 gene, but not other HTA genes, could phenotypically complement rat5 mutant plants when expressed from their native promoters. Expression analysis of HTA promoters indicated that they had distinct but somewhat overlapping patterns of expression in mature plants. However, only the HTA1 promoter was induced by wounding or by Agrobacterium infection of root segments. Our data suggest that, with respect to Agrobacterium-mediated transformation, all tested histone H2A proteins are functionally redundant. However, this functional redundancy is not normally evidenced because of the different expression patterns of the HTA genes.
