Control of nitrogen remobilization and senescence in Arabidopsis thaliana by DNA methylation dynamics. Control of nitrogen remobilization and senescence in Arabidopsis thaliana by DNA methylation dynamics

Senescence is altered in mutants that are defective in DNA methylation; in leaves the process of senescence is associated with very moderate initial decline in chromosomal methylation that reversed at later stages. Methylation changes were not specifically associated with senescence-associated genes and potential regulation of transcription factor binding is suggested. Overall design: Examination of cytosine methylation at four distinct timepoints after flower induction in A. thaliana
