A SAC phosphoinositide phosphatase controls rice development via hydrolyzing PI4P and PI(4,5)P2 (Plant Physiol)

As their name suggests, phosphoinositide (PI) phosphatases remove phosphates from phosphoinositides (try saying that fast!). Because the phosphorylation status of a membrane-bound PI determines which proteins it interacts with, PI phosphatases and kinases contribute to membrane functions and dynamics.…

Plasma membrane domain patterning and self-reinforcing polarity in Arabidopsis (Devel. Cell)

Phosphoinositides (PIs) are specialized membrane lipids that contribute to membrane nanodomains, which affect protein localizations and vesicle trafficking. Previous studies have implicated PIs in the polar localization of auxin-transporter PIN proteins, and, in roots, the PIN-regulators PAX and BRX.…

Design principles of a minimal auxin response system ($) (BioRxiv)

Auxin signaling components are evolutionarily conserved across the land plants and the duplication events in these regulators enabled complexity in development. Auxin regulated developmental programming occurs through the ARF (AUXIN RESPONSE FACTORS) transcriptional factors. Marchantia polymorpha serves…

Review: Formal description of plant morphogenesis (J Exp Bot) ($)

In recent years, a number of tools have been developed to describe and model plant morphogenesis, and these approaches have greatly informed our understanding of the molecular processes that underpin the control of growth. This excellent review by Pałubicki et al. is “an attempt to bring together…
