Trimtab-in-Training ‘s insight:

Fungi, in particular, basidiomycetous fungi, are very successful in colonizing microconfined mazelike networks (for example, soil, wood, leaf
litter, plant and animal tissues), a fact suggesting that theymaybe
efficient solving agents of geometrical problems. We therefore evaluated
the growth behavior and optimalityof fungal space-searching algorithms
in microfluidic mazes and networks. First, we found that fungal growth
behavior was indeed stronglymodulated bythe geometryof microconfinement. Second, the fungus used a complex growth and space-searching
strategycomprising two algorithmic subsets: 1) long-range directional
memoryof individual hyphae and 2) inducement of branching by
physical obstruction. Third, stochastic simulations using experimentally
measured parameters showed that this strategymaximizes both survival
and biomass homogeneityin microconfined networks and produces
optimal results onlywhen both algorithms are synergisticallyused. This
studysuggests that even simple microorganisms have developed adequate
strategies to solve nontrivial geometrical problems.
