A Phytochrome-Derived Photoswitch for Intracellular Transport
Cells depend on the proper positioning of their organelles, suggesting that active manipulation of organelle positions can be used to explore spatial cell biology and to restore cellular defects caused by organelle misplacement. Recently, blue-light dependent recruitment of specific motors to selected organelles has been shown to alter organelle motility and positioning, but these approaches la...
متن کاملImmunogold electron microscopy of phytochrome in Avena: identification of intracellular sites responsible for phytochrome sequestering and enhanced pelletability
Using monoclonal antibodies to the plant photoreceptor, phytochrome, we have investigated by immunogold electron microscopy the rapid, red light-induced, intracellular redistribution (termed "sequestering") of phytochrome in dark-grown Avena coleoptiles. Pre-embedding immunolabeling of 5-micron-thick cryosections reveals that sequestered phytochrome is associated with numerous, discrete structu...
متن کاملDesign and synthesis of donor-acceptor Stenhouse adducts: a visible light photoswitch derived from furfural.
The development of an easily synthesized, modular, and tunable organic photoswitch that responds to visible light has been a long-standing pursuit. Herein we provide a detailed account of the design and synthesis of a new class of photochromes based on furfural, termed donor-acceptor Stenhouse adducts (DASAs). A wide variety of these derivatives are easily prepared from commercially available s...
متن کاملRhizoid Differentiation in Spirogyra: III. Intracellular Localization of Phytochrome.
Localization of phytochrome which mediates rhizoid differentiation in Spirogyra was investigated. The red-absorbing form of phytochrome (Pr) seems to be distributed all over the cell periphery which remained in the centripetal end part after the centrifugation, as rhizoids formed equally well with red spotlight irradiation of three different parts of an end cell, i.e. distal end, middle, and pr...
متن کاملEffect of Ring Strain on the Charge Transport of a Robust Norbornadiene–Quadricyclane-Based Molecular Photoswitch
Integrating functional molecules into single-molecule devices is a key step toward the realization of future computing machines based on the smallest possible components. In this context, photoswitching molecules that can make a transition between high and low conductivity in response to light are attractive candidates. Here we present the synthesis and conductance properties of a new type of r...
