Simultaneous visualization of two protein complexes in a single plant cell using multicolor fluorescence complementation analysis
Bimolecular fluorescence complementation (BiFC) is an approach used to analyze protein–protein interaction in vivo, in which non-fluorescent N-terminal and C-terminal fragments of a fluorescent protein are rec...

Chloroplasts do not have a polarity for light-induced accumulation movement
Chloroplast photorelocation movement in green plants is generally mediated by blue light. However, in cryptogam plants, including ferns, mosses, and algae, both red light and blue light are effective. Although...

Low temperature-induced chloroplast relocation mediated by a blue light receptor, phototropin 2, in fern gametophytes
Chloroplast movement in response to light has been known more than 100 years. Chloroplasts move towards weak light and move away from strong light. Dark-induced relocation, called dark positioning, has also be...

Blue light diminishes interaction of PAS/LOV proteins, putative blue light receptors in Arabidopsis thaliana, with their interacting partners
The light, oxygen, or voltage (LOV) domain that belongs to the Per-ARNT-Sim (PAS) domain superfamily is a blue light sensory module. The Arabidopsis thaliana PAS/LOV PROTEIN (PLP) gene enc...

The fern as a model system to study photomorphogenesis
The fern gametophyte is a good model system for studying cell biological, physiological, and photobiological aspects of the fundamental processes of plant development and physiological phenomena, because of it...

Negative phototropic response of rhizoid cells in the fern Adiantum capillus-veneris
In general, phototropic responses in land plants are induced by blue light and mediated by blue light receptor phototropins. In many cryptogam plants including the fern Adiantum capillus-veneris, however, red as ...

Four distinct photoreceptors contribute to light-induced side branch formation in the moss Physcomitrella patens
Side branch formation in the moss, Physcomitrella patens, has been shown to be light dependent with cryptochrome 1a and 1b (Ppcry1a and Ppcry1b), being the blue light receptors for this response (Imaizumi et al. ...

Chloroplast Photorelocation Movement
Chloroplast photorelocation movement is a well-known phenomenon, which has been investigated since the 19th century and studied physiologically for more than 100 years. It is only very recently that genetic an...

Velocity of chloroplast avoidance movement is fluence rate dependent
In Arabidopsis leaves, chloroplast movement is fluence rate dependent. At optimal, lower light fluences, chloroplasts accumulate at the cell surface to maximize photosynthetic potential. Under high fluence rat...

Accumulation response of chloroplasts induced by mechanical stimulation in bryophyte cells
Chloroplast movement has been studied in many plants but mainly as a model system for light signaling. However, we recently showed that the avoidance response of chloroplasts is also induced by mechanical sti...

Chloroplast movement: dissection of events downstream of photo- and mechano-perception
The study of chloroplast photorelocation movement is progressing rapidly now that mutants for chloroplast movement have become available in Arabidopsis thaliana. However, mechanistic approaches in cell biology st...

The plant MITE m** is mobilized in anther culture
Transposable elements constitute a large portion of eukaryotic genomes and contribute to their evolution and diversification. Miniature inverted-repeat transposable elements (MITEs) constitute one of the main ...

Responses of ferns to red light are mediated by an unconventional photoreceptor
Efficient photosynthesis is essential for plant survival. To optimize photosynthesis, plants have developed several photoresponses. Stems bend towards a light source (phototropism), chloroplasts move to a plac...

Chloroplast avoidance movement reduces photodamage in plants
When plants are exposed to light levels higher than those required for photosynthesis, reactive oxygen species are generated in the chloroplasts and cause photodamage. This can occur even under natural growth ...

phot1 and phot2 mediate blue light regulation of stomatal opening
The stomatal pores of higher plants allow for gaseous exchange into and out of leaves. Situated in the epidermis, they are surrounded by a pair of guard cells which control their opening in response to many en...

Intracellular chloroplast photorelocation in the moss Physcomitrella patens is mediated by phytochrome as well as by a blue-light receptor
The light-induced intracellular relocation of chloroplasts was examined in red-light-grown protonemal cells of the moss Physcomitrella patens. When irradiated with polarized red or blue light, chloroplast distri...

Phytochrome-controlled phototropism of protonemata of the moss Ceratodon purpureus: physiology of the wild type and class 2 ptr–mutants
Phototropism and polarotropism in protonemata of the moss Ceratodon purpureus are controlled by the photoreceptor phytochrome. One class of phototropism mutants is characterised by growing randomly when kept for...
