Spaceflight represents a complex environmental condition in which several interacting factors such as cosmic radiation, microgravity and space magnetic fields are involved, which may provoke stress responses and jeopardize genome integrity. Given the inherent property of epigenetic modifications to

In this study,two elite rice inbred lines, Nipponbare and Mastumae were selected and irrigated with naphthalene solution with different concentrations. Epigenetic instabilities in the blade of the plants in tillering and heading stage were assessed by MSAP marks. The results showed that naphthalene

Transfers of organelle DNA to the nucleus established several thousand functional genes in eukaryotic chromosomes over evolutionary time. Recent transfers have also contributed nonfunctional plastid (pt)- and mitochondrion (mt)-derived DNA (termed nupts and numts, respectively) to plant nuclear

Molecular characterization of a rice mutator-phenotype derived from an incompatible cross-pollination reveals transgenerational mobilization of multiple transposable elements and extensive epigenetic instability.

BACKGROUND Inter-specific hybridization occurs frequently in plants, which may induce genetic and epigenetic instabilities in the resultant hybrids, allopolyploids and introgressants. It remains unclear however whether pollination by alien pollens of an incompatible species may impose a "biological

Epigenetic modifications including chromatin modifications and DNA methylation have emerged as essential marks that can influence various biological pathways in multicellular organisms. In plants, DNA methylation such as 5-methylcytosine (5mC) and N6-methyladenosine (6mA), which was discovered

OBJECTIVE Epigenetics is defined as mechanisms that regulate gene expression without base sequence alteration. One molecular basis is considered to be DNA cytosine methylation, which reversibly modifies DNA or chromatin structures. Although its correlation with epigenetic inheritance over

Targeted disruption of an orthologue of DOMAINS REARRANGED METHYLASE 2, OsDRM2, impairs the growth of rice plants by abnormal DNA methylation.

Recent methylome analyses of the entire Arabidopsis thaliana genome using various mutants have provided detailed information about the DNA methylation pattern and its function. However, information about DNA methylation in other plants is limited, partly because of the lack of mutants. To study DNA

Seed development is an important process of reproductive development and consists of embryo and endosperm development; both comprise several key processes. To determine and investigate the functions of the dynamic DNA methylome during seed development, we profiled the DNA methylation genome wide in
