Genetika domestikacije kmetijskih rastlin

diplomsko delo

Urša Lešnjak (Author), Jernej Jakše (Mentor)

Abstract

Pri domestikaciji ali udomačitvi določena vrsta postane le-ta odvisna od človeka tako, da ni več sposobna samostojno preživeti v svojem naravnem okolju. Poznamo že kar nekaj centrov domestikacije. Pomembno je, da je prišlo do sindroma udomačitve, da so se lahko rastline prilagodile na novo okolje in tudi tehnologije. Tako pride tudi do učinka ozkega grla, kar vpliva na gensko raznolikost. Z genetiko lahko spremljamo kako se spreminjajo populacije določenih rastlin. Prihaja do različnih fenotipskih sprememb. Spoznava se specifične gene, ki nadzorujejo vse te morfološke spremembe. Z genomskimi tehnologijami prihaja vedno znova do novih genskih podatkov, ki razjasnijo postopke udomačitve in omogočijo nadaljnje raziskave.

Secondary title:	ǂThe ǂgenetics of plant domestication
Secondary abstract:	Domestication is when a particular species becomes dependent on humans, so that it is no longer able to survive independently in its natural environment. We already know of some domestication centers. The important thing is that there was a domestication syndrome so that the plants could adapt to the new environment and technologies. This also leads to a bottleneck effect that affects genetic diversity. Using genetics, we can observe how populations of certain plants change. There are several phenotypic changes. The specific genes that control all these morphological changes are identified. With the help of genomic tehnologies, new genetic data is constantly being obtained which decipher domestication processes and are used for further research
