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…
Monitoring the fate of paternal mitochondria and their elimination in rice zygotes
UncategorizedAbstractMitochondria are preferentially transmitted from the maternal plant in most angiosperms, including rice, and paternal mitochondria are generally eliminated during microgametogenesis and/or in zygotes. The mechanism by which paternal mitochondria are eliminated progresses during plant reproductive…
DkMYB117, a novel MYB transcription factor, regulates gibberellin catabolism to control plant height in persimmon interstock systems
UncategorizedAbstractDwarfing cultivation is a transformative strategy in modern fruit tree management, yet the molecular underpinnings of interstock-induced dwarfism remain elusive in persimmon (Diospyros kaki Thunb.). Here, we unveil DkMYB117, a novel R2R3-MYB transcription factor, as a key molecular switch orchestrating…

Brown algae produce hydrocarbons via fatty acid photodecarboxylase-dependent and -independent pathways
UncategorizedAbstractAcross the tree of life, diverse organisms synthesize hydrocarbons (HCs) from fatty acids using various enzymes. In plants and insects, HCs are typically excreted (e.g. waxes, pheromones), whereas in algae, they seem to be mostly intracellular and membrane-associated. To date, all studied organisms…
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…
