Morphological changes that occur during filamentous growth in yeast. Under nutrient-rich conditions (left), yeast-form cells are round in shape and produce daughters that fully separate from their mothers. In haploid cells (shown), daughter cells (D1) bud back toward the mother cell (M) by axial budding (arrow toward left). Under nutrient-limiting conditions (right), cells become elongated and remain attached through Flo11. Daughter cells bud away from the mother cell (arrow toward right) by distal-unipolar budding by using the distal landmark Bud8. Signal transduction pathways (RAS-PKA and MAPK) regulate these changes.
