The yellow-in-the-dark chIL Chlamydomonas mutant as a model for time-resolved chloroplast biogenesis and retrograde signaling
UncategorizedAbstractUnderstanding chloroplast biogenesis is key given the importance of photosynthesis and chloroplast metabolism. Chloroplast assembly has been extensively studied in angiosperms, where the main hallmarks have been established, including the need for nuclear and plastid genome coordination through…
From seawater to pyrenoid – The molecular architecture of the diatom CO2-concentrating mechanism
UncategorizedAbstractDiatoms are the most successful group of algae and their photosynthesis accounts for up to 20% of annual global CO2 fixation. A key factor to their ecological success is the operation of an efficient biophysical CO2-concentrating mechanism (CCM) that enriches CO2 for fixation by ribulose 1,5-bisphosphate…
Crops of the Future: Reviving Neglected and Undertilized Crops for Global Nutrition Webinar Series (September 2 and 3)
UncategorizedAbout this Webinar Series: This webinar series will focus on underutilized crops, plant species of local or regional importance that have received limited attention in research, breeding, and policy compared with global staples such as rice, maize, and wheat. These crops hold significant potential to…
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…
miR169a-MhNF-YA2 module modulates H2S dosage-dependent lateral root formation via MhPIN1 and MhCYCB1;2 in Malus hupehensis
UncategorizedAbstractHydrogen sulfide (H2S) regulates lateral root (LR) formation dependent on its dosage, yet the underlying molecular mechanism remains not fully elucidated. Here, applying 0.5 mM and 0.05 mM NaHS promoted LR formation and upregulating miR169a expression in Malus hupehensis and Arabidopsis, respectively,…
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 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…
