Immunochemical Detection of Modified Species of Cytosine in Plant Tissues.
2021
Methylated cytosine (5-methylcytosine) is the most studied epigenetic mark involved in the regulation of gene expression. Although it displays highly variable dynamics during plant ontogenesis, it is possible to gain a fine spatial perspective with immunohistochemistry techniques that use specific antibodies and fluorochromes. Besides, there are other cytosine modifications described in plants, although their biological significance is still unknown (i.e., 5-hydroxymethylcytosine, 5-formylcytosine and 5-carboxylcytosine). Here we present a standardized protocol to detect cytosine modifications in plant tissues.
