Thresholds for georesponse to acceleration in gravity-compensated Avena seedlings.
TL;DR: The magnitude of acceleration required to induce growth responses in Avena seedlings grown in the absence of tropic response to earth gravity has been investigated and a clinostat was developed that imposes accelerations from about 10(-9) g to 3 g upon the seedling; simultaneously, it nullifies, or compensates for, response to the directional component of the gravitational-force vector by rotating the seedlings on a horizontal axis.
Journal ArticleDOI
Hormonal Relations in the Phototropic Response: III. The Movement of C14-labeled and Endogenous Indoleacetic Acid in Phototropically Stimulated Zea Coleoptiles
J. Shen-Miller,Solon A. Gordon +1 more
TL;DR: It is suggested that phototropism following unilateral irradiation with first positive radiant densities might be a consequence of lateral inequalities in the ability of the irradiated and shaded tissues to transport auxin basipetally.
Journal ArticleDOI
Gravitational Compensation and the Phototropic Response of Oat Coleoptiles
J. Shen-Miller,Solon A. Gordon +1 more
TL;DR: The phototropic response of the vertically rotated seedling was significantly different from that of the vertical stationary, indicating the importance of vertically rotated controls in clinostat experiments.
Journal ArticleDOI
Distribution and Activation of the Golgi Apparatus in Geotropism
J. Shen-Miller,Carol Miller +1 more
TL;DR: It is suggested that the Golgi participates in, and possibly initiates, the differential elongation of cells of geotropically stimulated coleoptiles as well as the kinetics of amyloplast sedimentation and Golgi movement do not appear to differ in the cells of the avascular tip.
Journal ArticleDOI
Rhythmicity in the Basipetal Transport of Indoleacetic Acid through Coleoptiles
TL;DR: The rate (per cent per minute) of basipetal transport of indoleacetic acid is periodic in various regions of the coleoptile, with a period of about 20 minutes, and the possible relation of this cyclic phenomenon to other rhythmic processes of similar periodicities is discussed.
