Abstract
Many mutations and phenotypic variations, which often fail to be explained by nucleotide changes with hereditary consequences, are supported by epigenetic analysis. In this study, we aimed to evaluate epigenetic changes in Wild and Mutant maize samples. This study is divided into two main experiments. The first experiment is transcriptome analysis of Wild and Mutant ear and tassel and screening of the gene clusters for epigenetic functions. Followed by the second experiment, where confirmation of the up- and down-regulated selected genes was performed in the studied samples. In the second experiment, a few new mutant plants are also added for comparative analysis. The data revealed that many genes histone modification, DNA methylation, ABC transporter and genes for seed maturation and pollen physiology exhibited up or down regulation in comparison to Wild samples. The probable role of these genes in the mutation of tassel-ear and mutant tassel is discussed.
期刊介绍：
Russian Journal of Genetics is a journal intended to make significant contribution to the development of genetics. The journal publishes reviews and experimental papers in the areas of theoretical and applied genetics. It presents fundamental research on genetic processes at molecular, cell, organism, and population levels, including problems of the conservation and rational management of genetic resources and the functional genomics, evolutionary genomics and medical genetics.
