abnormal activation of monopolar cell growth activation of monopolar cell growth at either end 2012-08-15T13:23:28Z A regulation phenotype observed in the vegetative growth phase of the life cycle in which the activation of monopolar cell growth may occur at either the new or old end of the cell, instead of exclusively at the old end, following cell division. A population of cells with this phenotype has a 1:1 mix of cells initiating growth at the new end and cells initiating growth at the old end. abnormal initiation of growth from either old or new end following cell division midori activation of monopolar vegetative cell growth at either end FYPO:0001394
