1. The circadian clock component OsRVE6a orchestrates daytime SA-JA signaling crosstalk to enhance rice defenses.
PMID:日期:2026-09-24Salicylic acid (SA) and jasmonic acid (JA) are key plant defense hormones that typically exhibit antagonistic interactions, with JA levels peaking during the day and SA at night. However, how plants sustain SA-mediated immunity during daylight when JA defenses dominate remains unclear. Here, we identify the rice oscillator gene OsRVE6aas a central regulator enabling simultaneous activation of SA and JA pathways during daytime biotic stresses. Daytime feeding by the small brown planthopper (SBPH) induces OsRVE6a expression and alters circadian rhythms in rice. OsRVE6a maintains phased JA and SA peaks, activates JA signaling via the receptor OsCOI1a to align JA signaling with JA content peaks, and alleviates their antagonism by suppressing OsNPR1. Concurrently, OsRVE6a directly activates OsNPR1-responsive defense genes such as OsWRKY20 and OsPR1 ensuring SA-responsive gene expression despite OsNPR1 reduction. Genetic analysis confirms that OsWRKY20 is essential for OsRVE6a-mediated SBPH resistance. These findings establish OsRVE6a as a molecular orchestrator linking circadian timing and immune coordination, enhancing rice resilience to biotic stresses.

2. PURE: An interpretable framework for prioritizing candidate regulators of differential gene expression in plants.
PMID:日期:2026-09-23While transcriptomic profiling has become routine, identifying the TFs underlying these expression patterns remains a major challenge, particularly for crops and non-model species lacking efficient transformation systems. To connect expression correlations with candidate regulatory mechanisms, we developed PURE (Plant Unified Regulation Explorer), an interpretable platform that ranks candidate TFs by integrating co-expression patterns with sequence motifs and experimental binding evidence. PURE uses gradient boosting to handle sparse and imbalanced plant regulatory matrices and then applies SHAP feature attribution to convert model behavior into TF-level contribution scores. By integrating ChIP-seq and DAP-seq resources from Arabidopsis, maize, rice, and tomato, PURE projects these reference binding profiles through cross-species relationships to constrain the search space in target species. Benchmarking across 11 species spanning the green lineage showed that PURE feature matrices captured expression contrasts associated with abiotic stress, developmental trajectories, and cell-type specificity, and downstream evidence-filtered attribution scores prioritized TF candidates supported by the integrated regulatory evidence. PURE further supported analyses of the transcriptional plasticity of maize C photosynthesis, the conserved photosystem response across lineages, and the hierarchical metabolic architecture of tomato fruit ripening. As a discovery-oriented test, PURE prioritized the less-characterized tomato light-dark TF SlDOF3, and integrated SlDOF3 ChIP-seq and RNA-seq analyses supported binding and associated expression changes at predicted pathway loci. PURE is accessible as a web resource (https://plantencodedb.sjtu.edu.cn/pure/), enabling experimental biologists to prioritize candidate TFs for downstream experimental analysis.

3. Single-nucleus transcriptomics reveals cell fate transitions and transcriptional programs driving bulblet formation in Lilium.
PMID:日期:2026-09-23Bulblet formation is a critical type of direct vegetative regeneration in plants, where modified leaf bases undergo a developmental transition to generate new bulb structures. However, the cellular trajectories driving this scale-to-bulblet transition remain poorly understood. Here, we applied single-nucleus sequencing to construct a high-resolution cellular atlas of lily bulblet formation. We identified a population of meristem-like cells located adjacent to vascular bundle sheath cells that exhibits progenitor-like features and transcriptional associations with vascular and parenchyma cell states during bulblet organogenesis. Furthermore, trajectory analyses suggest potential divergent transcriptional state shifts within parenchyma cells, highlighting transcriptional plasticity that may underlie bulb tissue differentiation. Cross-species comparative analyses further revealed a partially conserved meristem-associated transcriptional program together with Lilium-enriched regulatory features associated with developmental specification, hormonal responsiveness, and cellular reprogramming. Crucially, we identified and functionally validated BELLRINGER (LdBLR) and GENERAL REGULATORY FACTOR 12 (LdGRF12) as positive regulators of cell proliferation during bulblet formation and further revealed that the two proteins physically interact, supporting their participation in a common regulatory module. This work provides a comprehensive single-nucleus atlas of lily bulblet development and reveals both conserved and Lilium-enriched transcriptional programs associated with vegetative organ formation, offering a valuable framework for dissecting cellular and molecular mechanisms of regeneration in bulbous plants.

5. Lineage-specific enzyme optimization underlies divergent evolution of trans-Cinnamaldehyde and Eugenol biosynthesis in Cinnamomum cassia and Cinnamomum verum.
PMID:日期:2026-09-23Closely related plant species often exhibit striking diversity in their specialized metabolism, yet the genomic and evolutionary mechanisms driving this divergence are often elusive. The globally important cinnamon species Cinnamomum cassia and C. verum represent a classic example, producing leaf essential oils dominated by trans-cinnamaldehyde (t-CALD) and eugenol, respectively. Here, we combined chromosome-level genome assemblies for both species with comparative transcriptomics and biochemistry to decipher the molecular basis of this metabolic specialization. We show that, while the core phenylpropanoid pathway is largely conserved, the evolutionary innovation lies in the lineage-specific optimization of key terminal enzymes. A combination of enzyme kinetics, structural modelling and molecular dynamics simulations, and site-directed mutagenesis demonstrate that C. cassia possesses a 4-coumarate:CoA ligase (Cc4CL3) with strong substrate preference for trans-cinnamic acid, thus driving efficient t-CALD production. Furthermore, we found that low expression of CCR1 (cinnamoyl-CoA reductase), the key enzyme catalyzing cinnamoyl-CoA to t-CALD, likely limits t-CALD biosynthesis in C. verum. This expression divergence is associated with the presence of short tandem repeats (STRs) in the CcCCR1 promoter, which are absent in CvCCR1. In the eugenol biosynthetic pathway, the coniferyl alcohol acetyltransferase (CFAT) gene family has undergone pronounced expansion in C. verum. Notably, molecular dynamics simulations and site-directed mutagenesis reveal that CvCFAT5 has a deeper substrate-binding pocket than its ortholog in C. cassia, resulting in stable substrate binding and superior catalytic efficiency that drives elevated eugenol synthesis. Our study elucidates how distinct evolutionary trajectories-enzyme optimization and gene family expansion-can direct metabolic flux toward different metabolites in a species-specific manner, providing a genomic resource and a mechanistic framework for understanding metabolic diversification in plants.

6. A three-threshold gibberellin model defines tunable uncoupling of male fertility and growth to facilitate maize hybrid seed production.
PMID:日期:2026-09-18Efficient hybrid seed production requires controllable male sterility systems, yet how developmental processes can be selectively manipulated to disrupt male fertility while preserving vegetative growth remains poorly understood. Whether filament elongation represents a distinct hormonal sensitivity checkpoint and how its regulation can be exploited to uncouple male fertility from vegetative growth remain largely unknown. Here, we identify a series of gibberellin-sensitive genic male sterililty (GGMS) mutants carrying allelic variations in the maize GA biosynthetic gene ZmKAO. Unlike previously characterized GA-deficient mutants with broad defects in reproductive development, ggms mutants exhibit male sterility primarily due to defective filament elongation, while anther development, pollen maturation, and female fertility remain largely unaffected even under severe GA deficiency. Notably, filament elongation in GGMS mutants can be restored by a single GA application after tasseling. Genetic, biochemical, and molecular analyses support a model in which reduced D9 accumulation relieves D9-mediated repression of the filament-preferential transcription factor ZmMYB53, thereby enhancing ZmBXL7 expression and promoting filament cell elongation. Quantification of endogenous GA levels across a series of ZmKAO alleles with different functional strengths reveals a graded relationship between GA reduction and developmental outputs. While strong alleles (ggms1/2) cause severe growth defects, weak alleles (ggms3/4) uncouple vegetative growth from male fertility by selectively disrupting filament elongation. Based on these findings, we propose a three-threshold model in which different developmental processes exhibit distinct sensitivities to GA reduction. This framework enables rational selection and engineering of GGMS materials for maize hybrid seed production. Together, our study reveals a hierarchical GA sensitivity mechanism underlying maize reproductive development and provides both conceptual insights into hormone-regulated fertility and practical strategies for engineering controllable GGMS systems in maize.

8. Targeting a cryptic Magnaporthe oryzae-specific pocket in succinate dehydrogenase to combat rice blast.
PMID:日期:2026-09-15The global efficacy of succinate dehydrogenase inhibitors (SDHIs), a leading class of fungicides, is increasingly threatened by resistance, driven largely by their shared binding mode at the conserved ubiquinone-binding (Q) site. This challenge is particularly acute for rice blast, as no SDHI is registered for this disease and available compounds offer limited protection while remaining vulnerable to Q-site mutations. In this study, we identified a previously unrecognized, pathogen-adaptive pocket within the SDH complex of Magnaporthe oryzae, which is structurally distinct from the canonical Q site. Leveraging this finding, we performed virtual screening and identified PD13, a phenylhydrazine-derived inhibitor predicted to bind this region. Notably, PD13 impaired UQ recognition and catalysis, suppressed SDH activity, and triggered ATP depletion, while demonstrating field efficacy comparable to the conventional fungicide tricyclazole. Importantly, it remained fully active against a strain cross-resistant to multiple commercial SDHIs and exhibited low toxicity toward non-target organisms. Beyond introducing a new compound, this study expands the druggable landscape of a well-characterized target and provides a strategic proof of concept for exploiting noncanonical pockets in established fungicide targets.
