BR-ENHANCED EXPRESSION 1/2/3 fine-tune plant photomorphogenesis by regulating the phyA/B-SPA1 cascade
UncategorizedAbstractBR-ENHANCED EXPRESSION1 (BEE1), BEE2, and BEE3, key transcriptional components of brassinosteroid signaling, have been shown to play critical roles in regulating light signaling. However, the precise molecular mechanism by which BEE1/2/3 repress photomorphogenesis remains elusive. In this study,…
Dlo-miR164a-DlNAC100 module regulates floral bud induction by activating DlCOL4 expression in longan
UncategorizedAbstractLongan (Dimocarpus longan Lour.) is an economically significant subtropical crop of the Sapindaceae family. Floral bud induction is a critical process that directly determines fruit yield and quality in longan cultivation. However, the molecular mechanisms underlying floral bud induction remain…
Sorbitol dehydrogenase aids grain-fill and integrates carbohydrate metabolism with redox in the hypoxic maize endosperm
UncategorizedAbstractExtreme low oxygen is typical of microenvironments inside developing grains, thus requiring metabolic adaptations to hypoxia. Potential contributions from sorbitol dehydrogenase (SDH) are tested here for maize (Zea mays) since the reversible reaction (fructose + NADH ↔ sorbitol + NAD+) can…
TRANSPORTIN1 coordinates plant immune activation by mediating nuclear import of ADR1 helper NLRs
UncategorizedPlant NLR immune receptors can undergo dynamic changes in subcellular localization upon effector recognition. The Arabidopsis ADR1 helper NLRs mainly act at the plasma membrane (PM) in a phospholipid-dependent manner. Whether ADR1s display nuclear translocation and how ADR1s subcellular partitioning…
A PSA4–YCF4 complex promotes assembly of the photosystem I reaction center in Arabidopsis
UncategorizedAbstractPhotosystem I (PSI) is one of nature's most intricate and efficient nanomachines driving photosynthetic electron transfer. Its biogenesis requires a sophisticated, multi-step assembly pathway coordinated by a suite of nucleus- and plastid-encoded factors, yet the precise molecular mechanisms…
Derepression of BRANCHED1-Controlled Sucrose Hydrolysis Drives Bud Outgrowth and Phytoplasma-Induced Symptoms in Ziziphus jujuba
UncategorizedAbstractSugar metabolism and signalling play major roles in the early events of axillary bud outgrowth by repressing BRANCHED 1 (BRC1) expression. However, whether BRC1 controls sugar metabolism during the cessation of axillary bud growth remains unknown. In previous research it was shown that jujube…
Plant organelle division orchestrated by the mosaic machinery of endosymbiotic relics and eukaryotic host factors
UncategorizedAbstractPlastids retain the imprint of their cyanobacterial ancestry by dividing primarily through binary fission. This process is executed by elaborate division machinery that has continued to evolve since endosymbiosis. Early identification and characterization of the Arabidopsis accumulation and replication…
