Většina hub se živí saprotrofně rozkladem organické hmoty. Občas však změní svou ekologii a vstoupí do některé z užších symbióz s jinými organismy. V současnosti je k dispozici stále větší množství prací zabývajících se komparativní genomikou hub s rozdílnou životní strategií, což umožňuje odhalit trendy spojené mimo jiné se symbiotickým životem hub, ať už parazitickým, nebo mutualistickým. V tomto článku jsou představeny některé z nich.

Most fungi are saprotrophs living on de­caying organic materials. From time to time they change their ecology and enter into some kind of narrow symbiosis with other organisms. More and more compara­tive genome studies are emerging these days dealing with fungi with diverse life strategies, which present revealing trends, amongst other things, linked with a symbiotic, parasitic or mutualistic way of life. Some of these are introduced in the paper.
