Literature Sharing | Chinese cabbage orphan gene BR3 confers bolting resistance to Arabidopsis through the gibberellin pathway

Premature bolting affects yield and quality in Chinese cabbage, highlighting the importance of identifying bolting resistance genes. This study identifies an orphan gene, BR3 (BOLTING RESISTANCE 3), in Arabidopsis thaliana as a positive regulator of bolting resistance. BR3 is expressed during the seedling and flowering stages and localizes to the plasma membrane and nucleus. Overexpression of BR3 (BR3OE) delays bolting and flowering under both long-day and short-day conditions, with increased rosette leaf number and reduced plant height. Key flowering genes are downregulated in BR3OE plants. GA₃ treatment induces early flowering in both BR3OE and wild type (WT) plants, but BR3OE still flowers later than WT. In Chinese cabbage, BR3 shows co-expression with DELLA genes BrRGA1 and BrRGL3, suggesting a regulatory role through the GA pathway. This study offers new insights into bolting resistance mechanisms and provides valuable targets for breeding bolting-resistant Chinese cabbage varieties.

Literature Sharing | Regulation of co-translational mRNA decay by PAP and DXO1 in Arabidopsis

This study investigates the regulation of the co-translational mRNA decay (CTRD) pathway in Arabidopsis, a critical mechanism for maintaining mRNA homeostasis. The researchers found that 3ʹ-phosphoadenosine 5ʹ-phosphate (PAP), an inhibitor of exoribonucleases, affects CTRD activity. Specifically, they showed that loss of FRY1 impairs XRN4-dependent CTRD and that exogenous PAP treatment stabilizes CTRD target mRNAs. Additionally, they discovered that another PAP-sensitive exoribonuclease, DXO1, also contributes to CTRD, likely by acting on NAD⁺-capped mRNAs involved in stress responses. These findings reveal new layers of regulation and additional players in the CTRD pathway in plants.

Literature Sharing | Two pathogen-inducible UDP-glycosyltransferases, UGT73C3 and UGT73C4, catalyze the glycosylation of pinoresinol to promote plant immunity in Arabidopsis

This study uncovers a novel immune regulatory pathway in Arabidopsis thaliana involving two UDP-glycosyltransferases, UGT73C3 and UGT73C4, which are highly induced by Pseudomonas syringae infection. Overexpression of these genes enhances disease resistance, while their double mutation compromises immunity. Metabolomic analysis and biochemical assays reveal that UGT73C3/C4 glycosylate pinoresinol into its mono- and diglucoside forms, which promote immune responses by boosting ROS production and callose deposition. Additionally, the transcription factor HB34 directly activates UGT73C3/C4 expression, linking transcriptional regulation to glycosylation-mediated immunity. This work highlights the physiological significance of UGTs in plant defense through pinoresinol glycosylation.
