摘要：

We introduce a simple model of yeastlike growth of fungi colonies, which exhibits a continuous roughening transition far from equilibrium from a smooth (alpha = 0) to a rough phase (alpha = 1/2) in I + 1 dimensions. At the transition some scaling exponents are calculated by mapping the problem onto a directed percolation process. The model reproduces the roughening transition observed in some experiments of fungal growth. [S0031-9007(98)06963-4].
