Abstract: Abstract The phytochrome B mediated light signaling integrates with various phytohormone signalings to control plant immune response. However, it is still unclear whether phyB-mediated light signaling has an effect on the biosynthesis of jasmonate during… read more here.

DOI: 10.1038/s41467-024-47790-8
Abstract: Photoactivation of the plant photoreceptor and thermosensor phytochrome B (PHYB) triggers its condensation into subnuclear membraneless organelles named photobodies (PBs). However, the function of PBs in PHYB signaling remains frustratingly elusive. Here, we found that… read more here.

DOI: 10.1093/jxb/erab037
Abstract: Phytochrome B (phyB) senses the difference between darkness and light, the level of irradiance, the red/far-red ratio, and temperature. Thanks to these sensory capacities, phyB perceives whether plant organs are buried in the soil, exposed… read more here.

DOI: 10.1093/pcp/pcaf029
Abstract: Abstract Light is an essential environmental factor that facilitates the robust upward growth of post-germinative seedlings emerging from buried seeds that is partly mediated by the photoreceptors. Salinity stress hampers plant growth and development and… read more here.

DOI: 10.3390/ijms18061194
Abstract: The influence of temperature on plants is essential. However, our knowledge on the intricate regulation process underlying heat stress (HS) response in plants is limited. Recently, information about thermal sensors in vivo has begun to… read more here.
