Abstract

Epigenetska regulacija ima ključnu ulogu u mehanizmima biljnog odgovora na okolišne uvjete, bez promjene DNA sekvence. Različiti stresovi djeluju kao poticaj i mijenjaju razinu genske ekspresije pomoću metilacije DNA, modifikacije histona, djelovanja mikro RNA, aktivnosti transpozona i represijskog polikomb-kompleksa. Proučavanjem epigenetskih promjena povećavamo razumijevanje prilagodbe biljaka na stresne uvjete i mehanizam na kojem se ona temelji. Kod različitih poljoprivrednih kultura... More utvrđene su epigenetičke promjene u genomu koje su omogućile adaptabilnost kultura na stres suše. S obzirom na štetne učinke globalnih klimatskih promjena, osobito suše, korištenje epigenetskih razlika za razvoj adaptabilnijih sorti usjeva od velike je važnosti u oplemenjivanju bilja. Less

Abstract (english)

Epigenetic regulation plays a key role in the mechanisms of plant response to environmental conditions, without altering the DNA sequence. Different stresses stimulate a change in the gene expression through DNA methylation, histone modification, microRNA, transposon and repressive polycomb complex activity. We increase our understanding of plant adaptation to stressful conditions and the mechanism on which it is based by studying epigenetic changes. Epigenetic changes in the genome... More have been identified in different agricultural crops, which have enabled the adaptability of crops to drought stress. Given the detrimental effects of global climate change, particularly drought, the use of epigenetic differences to develop more adaptable crop varieties is of great importance in plant breeding.
