Heritable alteration in DNA methylation induced by nitrogen-deficiency stress accompanies enhanced tolerance by progenies to the stress in rice (Oryza sativa L.).

Abstract excerpt

Cytosine methylation is responsive to various biotic- and abiotic-stresses, which may produce heritable epialleles. Nitrogen (N)-deficiency is an abiotic stress being repeatedly experienced by plants. To address possible epigenetic consequences of N-deficiency-stress, we investigated the stability of cytosine methylation in rice (Oryza sativa L.) subsequent to a chronic (a whole-generation) N-deficiency at two...
