Plant shoot phototropism is triggered by the formation of a light-driven auxin gradient leading to bending growth.The blue light receptor phototropin 1(phot1)senses light direction,but how this leads to auxin gradient...
Mitochondria are frequently observed in the vicinity of chloroplasts in photosynthesizing cells, and this association is considered necessary for their metabolic in-teractions. We previously reported that, in leaf pal...
BACKGROUND: Phototropism is the response a plant exhibits when it is faced with a directional blue light stimulus. Though a seemingly simple differential cell elongation response within a responding tissue that resul...

Phototropin (phot)-mediated signaling initiated by blue light (BL) plays a critical role in optimizing photosyn- thetic light capture at the plasma membrane (PM) in plants. However, the mechanisms underlying the...

Chloroplast photo-relocation movement is crucial for plant survival; however, the mechanism of this phenome- non is still poorly understood. Especially, the signal that goes from photoreceptor to chloroplast is unknow...
Chloroplast movement is essential for plants to survive under various environmental light conditions. Photo- tropins--plant-specific blue-light-activated receptor kinases--mediate the response by perceiving light inte...
Phototropins (phot1 and phot2) are blue-light receptor kinases controlling a range of responses that optimize the photosynthetic efficiency of plants. Light sensing is mediated by two flavin-binding motifs, known as...
We thank Tong-Seung Tseng for verifying the efficacy of the cycloheximide treatment in stopping protein synthesis and Inseob Han and Margaret Olney for testing the phototropic sensitivity of the plants expressing PHOT::GFP in the double mutant background. We also thank all three of them for many useful discussions related to this study. This work was supported by National Science Foundation Grant 0444504. The authors are grateful for this support.
Phototropin 1 (photl) is a photoreceptor for phototropism, chloroplast movement, stomatal opening, leaf expansion, and solar tracking in response to blue light. Following earlier work with PHOTI::GFP (Sakamoto an...

The phototropins phot1 and phot2 are plant blue-light receptors that mediate phototropism, chloroplast movements, stomatal opening, leaf expansion, the rapid Inhibition of hypocotyl growth in etiolated seedlings, and ...
