Genome variability of plant somatic cells. 1. Variability during ontogenesis

Abstract: Сделан обзор литературных данных о геномной изменчивости соматических клеток в онтогенезе высших растений. Проанализированы явления эндоредупликации генома на разных стадиях развития растений, избирательной репликации и деамплификации, сходство, различия и механизмы геномной изменчивости у разных растений, функциональ ное значение и возможные причины геномной изменчивости, а также регуляции этой изменчивости. Особое внимание уделено возможной ключевой роли гормональной сис темы в регуляции геномной изменчивост… Show more

“…It should be noted that the phenomena of increasing the content of nuclear DNA and the number of individual repeats in cells and cell polyploidization during differentiation in the course of plant ontogeny have long been proven. High level of polyploidization is especially typical of highly differentiated cells and storage tissues (see for review [3,9]). Nevertheless, the issue of the relationship between the ploidy level of cultured cells of different plant species and the amount of accumulated BAC, and the overall produc ti vi ty of cultured tissue obviously requires further study.…”

“…The in vitro tissue culture allows researchers to produce aseptic biomass, enriched in secondary metabolites in environmentally-friendly way, over the whole year, with no harm to biodiversity. Furthermore, optimization of culture conditions for undifferentiated cell growth in vitro may notably increase the productivity of tissue culture in terms of target BACs [3,[6][7][8][9][10].…”
