Plasmopara viticola effector PvRxLR24 (a potential phosphatase) interferes grapevine stomatal immunity by targeting VvOST1
UncategorizedAbstractNumerous pathogens invade plants through stomata, and plants, on the other hands, could close the stomata after sensing the pathogens PAMPs. Subsequently, pathogens could overcome this plant immune response with their phytotoxins and effectors. A previous study showed that Plasmopara viticola,…
DNA hypermethylation of abscisic-acid-related genes helps enhance the cold tolerance of tetraploid rice
UncategorizedAbstractPolyploid plants exhibit enhanced stress resistance and superior adaptability to extreme environments, but the underlying molecular mechanisms remain incompletely understood. Here we confirm that tetraploid rice exhibits stronger cold tolerance than diploid rice. This improved tolerance is mediated…
Dual disruption of MiMPK4-mediated phosphorylation and interaction with MiRAP2.11 is required for blue light-induced carotenoid biosynthesis in mango fruit
UncategorizedAbstractLight regulates carotenoid biosynthesis in plants at multiple levels. However, the involvement of protein phosphorylation in light-induced carotenoid biosynthesis remains largely unexplored. Our previous studies demonstrated that blue light promotes carotenoid biosynthesis in mango fruit. In…
A cryptic START domain regulates deeply conserved transcription factors
UncategorizedAbstractTranscription factors (TFs) integrate a diverse array of inputs to achieve the exquisite control of gene expression necessary for life. In plants, this is exemplified by the deeply conserved CLASS III HOMEODOMAIN LEUCINE ZIPPER (HD-Zip III) family of TFs. HD-Zip III activity is controlled by…
Expanding the repertoire of microRNA target mimicry in plants
UncategorizedAbstractmicroRNAs (miRNAs) are master regulators of gene expression, guiding ARGONAUTE proteins to bind to and repress target RNAs. Interestingly, a special class of target RNAs, termed target mimics (TMs), can in turn trigger miRNA degradation in plants—a process genetically dependent on the F-box…
Combining timelapse imaging resolved leaf water potential with gas exchange provides insights into stomatal control by water
UncategorizedAbstractStomatal responses to changes in leaf water status are amongst the most important responses of guard cells for balancing carbon gain with water loss, yet we do not know if guard cells are hydraulically linked to the water status of the leaf across vascular land plants. We combined time-lapsing…
The hyccin-containing protein ECDR1 interacts with PI3K1 and PI4K1 and regulates broad-spectrum disease resistance in rice
UncategorizedAbstractProgrammed cell death and immunity in plants are finely orchestrated to promote antimicrobial defense while preventing autoimmunity. However, the molecular mechanisms involved are not fully understood. Here, we isolated a rice mutant ecdr1 (enhanced cell death and resistance 1) that displayed…
