Domain swapping to assess the mechanistic basis of Arabidopsis phototropin 1 receptor kinase activation and endocytosis by blue light.

Phototropins (phot1 and phot2) are plasma membrane-associated receptor kinases that respond specifically to blue and UV wavelengths. In addition to a C-terminal Ser/Thr kinase domain, phototropins contain two N-terminal chromophore binding LOV domains that function as photoswitches to regulate a wide range of enzymatic activities in prokaryotes and eukaryotes. Through domain swapping, we show t...

Enhancement of blue-light sensitivity of Arabidopsis seedlings by a blue light receptor cryptochrome 2.

Cryptochrome is a group of flavin-type blue light receptors that regulate plant growth and development. The function of Arabidopsis cryptochrome 2 in the early photomorphogenesis of seedlings was studied by using transgenic plants overexpressing CRY2 protein, and cry2 mutant plants accumulating no CRY2 protein. It is found that cryptochrome 2 mediates blue light-dependent inhibition of hypocoty...

Phototropin blue light receptors and light-induced movement responses in plants.

Two blue light receptors in Arabidopsis, termed phot1 and phot2, which contain flavin chromophores and have intrinsic protein kinase activity, participate in several physiological processes. Lin looks at the genetic evidence regarding how these photoreceptors mediate blue light-induced phototropism, chloroplast relocalization, and opening of the stomatal aperture.

Blue light activates calcium-permeable channels in Arabidopsis mesophyll cells via the phototropin signaling pathway.

Light is a central regulator of plant growth and development. Among the processes triggered by blue and UV-A light, phototropism, stomatal movement, and chloroplast orientation rely on the activation of blue-light receptors known as phototropins. So far, these photoreceptors constitute a class of light receptor kinases unique to the plant kingdom. In Arabidopsis thaliana, the two members phot1 ...

Blue Light-Induced Proteomic Changes in Etiolated Arabidopsis Seedlings

Plants adapt to environmental light conditions by photoreceptor-mediated physiological responses, but the mechanism by which photoreceptors perceive and transduce the signals is still unresolved. Here, we used 2D difference gel electrophoresis (2D DIGE) and mass spectrometry to characterize early molecular events induced by short blue light exposures in etiolated Arabidopsis seedlings. We obser...
