The PHO1 protein family in phosphate export and beyond
UncategorizedAbstractThe Arabidopsis thaliana PHOSPHATE 1 (PHO1) was first identified as an inorganic phosphate (Pi) exporter mediating Pi loading into the root xylem. PHO1 is the prototypical member of a family of eukaryotic proteins possessing both an SPX and EXS domain. Recent cryo-EM structures of both the Arabidopsis…

BAM3 Is a CLE19 Receptor that Mediates a Distinct Signaling Branch Controlling Tapetum Degeneration and Pollen Wall Formation
UncategorizedAbstractPollen wall formation requires precise coordination between tapetum differentiation, metabolism, and programmed cell death. In Arabidopsis, the microspore-derived peptide CLE19 restricts tapetal activity to maintain pollen wall homeostasis, yet how CLE19 signaling achieves developmental specificity…
DNA-binding activity of PIF7 links phytochrome B signaling to plant responses to vegetation proximity
UncategorizedAbstractPHYTOCHROME INTERACTING FACTORs (PIFs) are transcription factors that act as central signaling hubs in light regulated processes. All PIFs contain an Active Phytochrome B Binding (APB) motif and a DNA-binding basic-helix-loop-helix (bHLH) domain. In the shade-avoider Arabidopsis thaliana, PIF7…
From oxime to signal molecules: Indole-3-acetaldoxime undergoes oxidation to produce nitric oxide and indole-3-acetic acid
UncategorizedAbstractIndole-3-acetaldoxime (IAOx) has long been placed in auxin metabolism as a tryptophan-derived precursor that may feed indole-3-acetic acid (IAA) production through indole-3-acetonitrile (IAN) and indole-3-acetamide (IAM). However, recent genetic and biochemical evidence indicates that IAOx-derived…
LED white light suppresses ethylene biosynthesis in apple fruit
UncategorizedAbstractAs a typical climacteric fruit, the apple (Malus domestica) ripening is predominantly regulated by ethylene. Light-emitting diode (LED) white light, an energy-efficient and widely promoted light source, can significantly inhibit ethylene biosynthesis during apple ripening, however, its underlying…
