We have analyzed DNA methylation of plastid DNA from fully ripened red fruits, green mature fruits, and green leaves of tomato (Lycopersicon esculentum var. Firstmore). Essentially identical restriction profiles were obtained between chromoplast and chloroplast DNAs by EcoRI digestion. BstNI/EcoRII and HpaII/MspI are pairs of isoschizomers that can discriminate between methylated and unmethylat...
Methylation of cytosine to 5-methylcytosine (mC) is the most important epigenetic DNA alteration in eukaryotes. Cytosine methylation is involved in establishing a silenced chromatin stage through interaction with DNA-binding proteins and recruitment of histone deacetylases and other histone-modifying enzymes leading to chromatin remodeling. In this fashion, DNA methylation is connected with pro...
The transcription factor nuclear factor1-C2 (NF1-C2) mediates the action of prolactin in the mammary gland. Research on the molecular genetic mechanism of model system have indicated that the NF1-C2 gene plays an important role for the activation of several mammary gland specific genes (Nilsson et al. 2006). Moreover, the effects of prolactin on milk production traits have been reported in rumi...
Expression of mutant EcoRII methyltransferase protein (M.EcoRII-C186A) in Escherichia coli leads to tightly bound DNA-protein complexes (TBCs), located sporadically on the chromosome rather than in tandem arrays. The mechanisms behind the lethality induced by such sporadic TBCs are not well studied, nor is it clear whether very tight binding but non-covalent complexes are processed in the same ...
