Differences in the Manifestation of Cell Pluripotence In Vivo and In Vitro in the Mutant Arabidopsis thaliana with the Phenotype of Cell Memory Disorder

Abstract Plant cells cultivated in vitro are a convenient model for studying the genetic and physiological mechanisms necessary to acquire state of pluripotency. Earlier studies on plant Arabidopsis thaliana (L.) Heynh. have identified key role genes that determine pluripotency shoot apical meristem de novo regeneration tissue culture. In accordance with this, mutant plants higher level expression were characterized by an increased potential regeneration. The tae was exception this rule. resumed cell proliferation at late stages leaf development, which indicates violation maintaining epigenetic cellular memory. At same time, cultured showed lower proliferative activity compared wild type not capable shoots. A decrease regenerative important memory response exogenous hormones. Impaired differences their capacities planta make unique modifications regulation
