Across the plant kingdom, phytochrome (PHY) photoreceptors play an important role during adaptive and developmental responses to light. In Arabidopsis thaliana, light-activated PHYs accumulate in the nucleus, where they regulate downstream signaling

An Evolutionarily Conserved Signaling Mechanism Mediates Far-Red Light Responses in Land Plants

Autor: Anja Possart, Andreas Hiltbrunner

Publikováno v: The Plant Cell. 25:102-114

Phytochromes are plant photoreceptors important for development and adaptation to the environment. Phytochrome A (PHYA) is essential for the far-red (FR) high-irradiance responses (HIRs), which are of particular ecological relevance as they enable pl

Pollen Tube Tip Growth Depends on Plasma Membrane Polarization Mediated by Tobacco PLC3 Activity and Endocytic Membrane Recycling

Autor: Diana Helling, Stephanie Cottier, Benedikt Kost, Ulrich Klahre, Anja Possart

Publikováno v: The Plant Cell. 18:3519-3534

Phosphatidyl inositol 4,5-bisphosphate (PI 4,5-P2) accumulates in a Rac/Rop-dependent manner in the pollen tube tip plasma membrane, where it may control actin organization and membrane traffic. PI 4,5-P2 is hydrolyzed by phospholipase C (PLC) activi

Shedding (far-red) light on phytochrome mechanisms and responses in land plants

Autor: Christian Fleck, Anja Possart, Andreas Hiltbrunner

Publikováno v: Plant Science, 217-218, 36-46
Plant Science 217-218 (2014)

In order to monitor ambient light conditions, plants rely on functionally diversified photoreceptors. Among these, phytochromes perceive red (R) and far-red (FR) light. FR light does not constitute a photosynthetic energy source; it however influence
