Abstract

Diplomska naloga opisuje molekularne in epigenetske mehanizme, ki prispevajo k prilagoditvi rastlin na stresne pogoje, s posebnim poudarkom na sušnih razmerah. Namen raziskave je bil ugotoviti, kako lahko epigenetske spremembe, kot je metilacija DNA, vplivajo na fenotipsko plastičnost rastlin ter ali te spremembe postanejo dedne in trajne skozi več generacij. Podatke so pridobili z eksperimenti izvedenimi s kontroliranim izpostavljanjem rastlin blagim stresnim pogojem, medtem ko so bile molekularne spremembe spremljane z naprednimi tehnikami, kot so analize izražanja genov in epigenetskih vzorcev. Ugotovljeno je bilo, da rastline razvijejo prilagoditve na sušne pogoje, vendar te epigenetske spremembe niso nujno trajne in se ne prenašajo vedno na naslednje generacije. Naloga nadalje analizira potencialne aplikacije teh ugotovitev v kmetijstvu, vključno z možnostjo selekcije rastlin, ki so bolj odporne na okoljske stresne dejavnike. Rezultati raziskave nakazujejo na omejeno transgeneracijsko dednost epigenetskih sprememb, kar ima pomembne posledice za razvoj novih strategij za izboljšanje pridelkov in trajnostne kmetijske prakse. Opisane raziskave odpirajo pot za nadaljnje študije, ki bi se osredotočile na dolgoročne učinke epigenetskih modifikacij in njihovo vlogo pri prilagajanju rastlin na spreminjajoče se okoljske pogoje.

Secondary title: Influence of epigenetic factors on plant disease resistance
Secondary abstract: This thesis describes the molecular and epigenetic mechanisms that contribute to plant adaptation to stress conditions, with a particular focus on drought environments. The aim of the research was to determine how epigenetic changes, such as DNA methylation, affect the phenotypic plasticity of plants and whether these changes become heritable and persistent across multiple generations. Described experiments were conducted by subjecting plants to controlled mild stress conditions while monitoring molecular changes using advanced techniques such as gene expression analysis and epigenetic pattern profiling. It was found that plants develop adaptations to drought conditions, but these epigenetic changes are not necessarily permanent and do not always transmit to subsequent generations. The thesis further examines the potential applications of these findings in agriculture, including the possibility of selecting plants that are more resilient to environmental stressors. The described research results indicate a limited transgenerational inheritance of epigenetic changes, which has significant implications for developing new strategies to improve crop yields and promote sustainable agricultural practices. Described studies pave the way for further research focusing on the long-term effects of epigenetic modifications and their role in plant adaptation to changing environmental conditions.
