Phototropic
Definition:
(a.) Same as Heliotropic.
Example Sentences:
(1) After sporangiophores were initially adapted symmetrically to a fluence rate of 1 W m-2 (447 nm), they were exposed to unilateral subliminal light (subthreshold for phototropism) of variable wavelength and fluence rate, and then to unilateral test light (447 nm) of fluence rate either 10(-3) or 10(-5) W m-2.
(2) Phototropic and light growth responses of the sporangiophore of Phycomyces have been elicited using tunable laser stimulation from 575 to 630 nm.
(3) To investigate the influence of calcium on dark adaptation, the phototropic latency method was employed with the modification that sporangiophores were temporarily immersed in solutions containing CaCl2 or LaCl3.
(4) A phototropic mechanism is proposed which combines the features of local adaptation and photoreceptor rotation.
(5) Conversion to a continuous temporal stimulus insures that phototropism never adapts as long as the spatial asymmetry in illumination is maintained.
(6) The HPLC elution profiles of the wild type were compared to a set of phototropism mutants (genotype mad) with specific defects in the light-transduction pathway.
(7) Experimental evidence indicates that during phototropism, Phycomyces sporangiophores use their own net rotation to convert an apparently spatial stimulus to a temporal one.
(8) The differences in codon usage for the fru operon versus the photosynthetic genes may reflect different proportions of the various tRNA specific for certain amino acids when cells are grown under heterotrophic versus phototropic conditions.
(9) The phototropic stimulus straddles the edge between light- and dark-adapted regions, and the differing responses of the two regions affects the direction of phototropic bending.

(12) The sporangiophores of Phycomyces do not exhibit phototropic responses when growth is arrested reversibly by cooling to 1 degrees C. Unilateral UV stimuli (254 nm) applied during cold periods are stored for at least 2 hr and produce tropic responses away from the light after warm-up.
