Negative phototropism in the piloboloid mutants of Phycomyces blakesleeanus Bgff.

Planta, 1984
The sporangiophore (spph) of a piloboloid mutant, genotype pil, of Phycomyces ceases elongation and expands radially in the growth zone shortly after reaching the developmental stage IV b. The pil spph is always negatively phototropic to unilateral visible light when its diameter exceeds 210 μm. Photoinduction of spph initiation, light-growth response,

Negative Phototropism of Phycomyces in the Ultra-violet

Nature, 1957
IN the course of a study of the growth and curvature of the sporangiophores of Phycomyces, the phototropic sensitivity was re-examined. Preliminary experiments showed that unfiltered green light, isolated from a General Electric H85C3 capillary mercury lamp by a Bausch and Lomb grating monochromator with quartz optics, caused very marked negative ...

UV susceptibility and negative phototropism of dermatophytes

Mycoses, 1995
Summary. High doses of ultraviolet radiation (UVR) have well‐known inhibitory effects upon dermatophytes. In the present study, the effect of repetitive low doses of UVR on mycelial growth of dermatophytes was tested. Pellets of Trichophyton rubrum, T.

Phototropin2-mediated hypocotyl phototropism is negatively regulated by JAC1 and RPT2 in Arabidopsis

Plant Physiology and Biochemistry, 2021
Hypocotyl phototropism is redundantly mediated by phot1 and phot2, two blue light receptor phototropins, under the intensity of blue light>1 μmol m-2 s-1. As light intensity increases, phot1 inhibits the phot2-mediated response. To date, only Arabidopsis Root Phototropism2 (RPT2) has been shown to participate in phot1-mediated inhibition of ...

Negative phototropism of rice root and its influencing factors

Science in China Series C, 2002
Some characteristics of the rice (Oryza sativa L.) root were found in the experiment of unilaterally irradiating the roots which were planted in water: (i) All the seminal roots, adventitious roots and their branched roots bent away from light, and their curvatures ranged from 25 degrees to 60 degrees .
