Usmrtit je, či nechat kolonizovat? To je otázka, kterou rostlině pomáhá řešit její imunita v reakci na všudypřítomné mikroby. Jakým způsobem rozpoznat, že jde o „přítele“ (symbionta), nebo „nepřítele“ (patogen)? Pokud jde o patogen, jak mu zabránit v úspěšné infekci efektivním způsobem? Znalosti o imunitě rostlin nám umožní snížit negativní dopady mikrobů na pěstování zemědělských plodin.

Kill it or get colonized? That is the question which immunity helps to solve for plants in response to ubiquitous microbes. But how can you tell if the microbe is a „friend“ (symbiont) or a „foe“ (pathogen)? And if it is a pathogen how can you effectively block its infection? A more thorough knowledge of plant immunity will help us to find a way to decrease the negative impact of pathogens on agriculture.
