Povzetek

Rastline so stacionarni organizmi, ki nimajo živčnega sistema, vendar so kljub temu lahko razvile različne pristope in odgovore na zaznavanje sprememb iz okolja. Zaradi segrevanja ozračja postaja problematika okoljskih sprememb vedno večja in je aktualna tudi pri rastlinah, predvsem v povezavi s kmetijstvom. Zaradi večanja števila prebivalstva se je povečala tudi potreba po večjem pridelku, ki pa je zaradi segrevanja ozračja izpostavljen številnim stresnim dejavnikom, ki negativno vplivajo na rast. Mednje spada tudi pomanjkanje vode oziroma suša, na katero so se rastline morale prilagoditi in s tem razviti nove sisteme. Različne raziskave so potrdile, da so se rastline na pomanjkanje vode sprva prilagodile tako, da so pospešile signalizacijo med zaznavo pomanjkanja in samim odzivom. Druge prilagoditve so povezane z ekspresijo genov in regulacijo bioprocesov v sami rastlini. V diplomski nalogi se osredotočam predvsem na do sedaj poznane molekularne vidike prilagoditve rastlin na pomanjkanje vode.

Sekundarni naslov:	Responses to drought stress in plants
Sekundarni povzetek:	Plants are sessile organisms that do not have a nervous system, but they have nevertheless been able to develop different approaches and responses to sensing changes in the environment. Due to the warming of the atmosphere the problem of environmental changes is getting more and more important and is also relevant for plants, especially in connection with agriculture. Due to the increase in the population, the need for plant products also increased, but because of the global warming they are exposed to many stress factors that have a negative effect on growth. Among the stress factors is also lack of water or drought, to which the plants had to adapt and thus develop new systems. Various studies have confirmed that plants initially adapt to water deficiency by speeding up the signalling cascade between the perception of scarcity and the response itself. Other adaptations are related to gene expression and regulation of bioprocesses in the plant itself. In my bachelor thesis, I mainly focus on the till now known molecular aspects of plant adaptation to water deficiency.
