Phycomyces: Distribution of Growth Velocities in the Growing Zone 1
AUTOR(ES)
Gamow, R. Igor
RESUMO
Distribution of growth velocities in the growing zone of stage IVb Phycomyces sporangiophores was measured by photographing the growing zone after dusting it with starch grains. When the entire growing zone is fully dark-adapted to red light and then subjected to a saturating white light stimulus, the entire growing zone increases in growth rate. When the growing zone is partially light-adapted, again the entire growing zone responds when subjected to a saturating white light stimulus but to a lesser degree than the fully dark-adapted sporangiophore. Phototropic mutants of class 1 and class 2 show a distribution of growth in the growing zone similar to wild type sporangiophores both during steady-state growth and during light-stimulated growth.
