Mightier than Muscle: A Near-atomic View of Pollen Actin Filaments
Research, The Plant Cell, The Plant Cell: In a NutshellBeyond its well-known role in muscle contraction, the cytoskeletal component actin participates in many critical cellular processes. Globular actin polymerizes into thin, flexible filaments that assemble into dynamic higher-order structures, such as bundles and networks. In addition to providing mechanical…

PIF8: a new player in far-red light signaling
Research, The Plant Cell, The Plant Cell: In a NutshellOh et al. identify a far-red light-specific role for PIF8.
Plant Cell https://doi.org/10.1105/tpc.19.00515
By Jeonghwa Oh, KAIST
Background: When plants are in the dark, their stems get longer to search for light. When reaching the light, plant photoreceptors called phytochromes perceive light…
An Improved Recombineering Toolset for Plants
Research, The Plant Cell, The Plant Cell: In a NutshellBrumos and Zhao et al. developed an improved set of genetic tools to make precise sequence modifications in large DNA fragments and used them to tag hundreds of plant genes, including those involved in auxin production.

Arabidopsis OR Represses the Greening of Cotyledons while It Is in the Nucleus
Research, The Plant Cell, The Plant Cell: In a NutshellSun et al. showed that OR interacts with TCP14 in the nucleus of dark-germinated seedlings and reduces chlorophyll biosynthesis, thylakoid membrane development and expression of EARLY LIGHT-INDUCIBLE PROTEINS, and that subsequent illumination relieves this repression.
