Turning over a green leaf: integrating light signals towards chloroplast establishment
UncategorizedAbstractLight is indispensable for transitioning from a heterotrophic to a photoautotrophic state. Etiolated seedlings, developed in darkness, are primed for rapid chloroplast development upon light exposure. In this transition, dark-adapted etioplasts differentiate into functional chloroplasts through…
Call to Action: Protect Merit-Based Federal Research Funding
UncategorizedThe White House Office of Management and Budget (OMB) has proposed significant changes to the Uniform Guidance, the government-wide framework governing federal financial assistance. Of particular concern to the research community are proposed changes that could increase political and administrative oversight…
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…
The OsMYB103-OsGLOX5 module regulates tapetum degradation and male fertility in rice
UncategorizedAbstractAnther tapetum degradation is essential for normal pollen formation in rice, yet the underlying regulatory network remains poorly understood. We isolated a novel male sterility rice mutant, osglox5, and confirmed that the target gene LOC_Os11g06870 encodes a glyoxal/galactose oxidase protein…
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…
