Time–Space-Resolved Fluorescence Spectroscopy in Chlamydomonas Cells under Light-Harvesting Regulation
UncategorizedAbstractWe report here a technical advancement that enables time-resolved fluorescence spectroscopy in spatially resolved domains of a living cell at low temperatures. The technique is based on a combination of a self-developed cryo-confocal microscope and a streak camera. An instrumental response time…
The MfMYB1–MfWRKY51/MfLBD1 regulatory switch modulates anthocyanin biosynthesis under low temperatures
UncategorizedAbstractSeasonal leaf coloration, driven by anthocyanin dynamics, is a crucial adaptive response to thermal environments, yet the underlying transcriptional mechanisms remain largely elusive. Here, we utilized the ornamental crabapple Malus ‘Fengwu’, which exhibits a striking red-to-green transition…
MnWRKY22 Mediates Tissue-Specific Resveratrol Biosynthesis through Coordinated Regulation of the Stilbene Synthase Gene Cluster in Mulberry
UncategorizedAbstractResveratrol, a pharmaceutically significant stilbenoid accumulates in mulberry roots. To elucidate the molecular mechanism underlying this tissue-specific biosynthesis, we systematically analyzed the stilbene synthase (STS) gene family in mulberry. Our investigation revealed that nine out of…
Conserved DNA methylation architectures are associated with transcriptional robustness and regulatory plasticity in the woody perennial tea plant
UncategorizedAbstractDNA methylation is an important mechanism in plant development and environmental adaptation, yet how distinct methylation features contribute to transcriptional stability and regulatory flexibility in long-lived woody plants remains poorly understood. Here, we integrated DNA methylomes, transcriptomes,…

CHH demethylation of the BcMAM1 promoter contributes to cold tolerance in autotetraploid wucai (Brassica campestris L.)
UncategorizedAbstractPolyploidization has long been recognized as a driving force in plant adaptation to adverse environments. Chilling injury poses a major challenge to global crop production, and the regulatory hierarchies that govern cold adaptation in polyploid crops are unexplored. Here, we show that tetraploid…
The MBW complex regulates floral volatiles in petunia: transcriptional repressor EOBV is a MYB component of the complex
UncategorizedAbstractAnthocyanin biosynthesis in Petunia is regulated by the bHLH AN1 and the WDR protein AN11, which together with interchangeable MYBs form the MYB–bHLH–WDR (MBW) complex. As they share the same biosynthetic pathway, anthocyanins are interlinked with phenylalanine-derived volatiles. However,…
Convergent evolution of an oxidative damage tolerance mechanism preserves replication fidelity in plant organellar DNA polymerases
UncategorizedAbstractPlant mitochondria and chloroplasts are sources of reactive oxygen species (ROS) that trigger oxidative DNA lesions. Among these, 8-oxo-7,8-dihydroguanine (8-oxodG) is particularly mutagenic because it exhibits ambiguous base pairing, as DNA polymerases efficiently incorporate adenine opposite…
