Summary The basic amino acids lysine and ornithine are precursors to bioactive alkaloids including nicotine, hyoscyamine, and securinine. The amino acids can be incorporated into alkaloids in a symmetric or nonsymmetric manner. Here, we report the discovery of enzymes responsible for the nonsymmetric pathway. We used transcriptomics and enzyme characterisation, including mutagenesis and isotope labelling, to identify the enzyme catalysing the nonsymmetric lysine incorporation step of securinine biosynthesis in Flueggea suffruticosa . We then used phylogenetics to expand the investigation across plants and identified orthologs from Nicotiana tabacum and Artemisia annua . We report the ornithine/lysine/arginine decarboxy‐oxidases (OLADOs), pyridoxal phosphate (PLP)‐dependent enzymes responsible for the nonsymmetric pathway, catalysing the single‐step decarboxylative oxidative deamination of lysine, ornithine, or arginine. These enzymes are part of the group III ornithine/lysine/arginine decarboxylase‐like family (OLADLs), previously associated with prokaryotes. We show that OLADLs are widespread in plants and that OLADOs have repeatedly emerged from OLADLs through parallel evolution. This investigation introduces a new class of eukaryotic decarboxylases and describes enzymes involved in multiple alkaloid biosynthesis pathways. It furthermore demonstrates how the principle of parallel evolution at a genomic and enzymatic level can be leveraged for gene discovery across multiple lineages.

Transcription factors (TFs) play a critical role in regulating the expression of drought-responsive genes. Elucidating how TFs are modulated by stress signals will contribute to deciphering the impacts of drought on transcriptional regulation. We discovered that the mutation of an HD-Zip IV TF ZmOCL1 (OUTER CELL LAYER1) enhances susceptibility to water deficit. Transcriptome analysis and biochemical evidence demonstrated that a dehydrin gene ZmDHN2 is one of the direct target genes of ZmOCL1. Overexpression of ZmDHN2 in maize confers drought resistance by regulating stomatal closure, elevating peroxidase activity, and reducing hydrogen peroxide accumulation. Screening for an upstream kinase of ZmOCL1 identified a mitogen-activated protein kinase (MAPK) ZmMPK5, which is activated by dehydration. ZmMPK5 phosphorylates ZmOCL1 at the Ser283 residue and increases its binding affinity to the ZmDHN2 promoter, leading to full induction of ZmDHN2. Overexpression of ZmMPK5 improves drought tolerance and raises the transcription of ZmDHN2 compared to wild-type maize, while knockout of ZmMPK5 results in sensitivity to drought and a decrease in ZmDHN2 transcription. Our work reveals a transcriptional regulatory module in which ZmOCL1 promotes the expression of ZmDHN2 after being phosphorylated by ZmMPK5 in response to drought stress, finally resulting in better adaptation to water scarcity.
转录因子在调控干旱响应基因表达中起着至关重要的作用。阐明tf是如何被胁迫信号调节的，将有助于破译干旱对转录调控的影响。我们发现HD-Zip IV TF ZmOCL1 （OUTER CELL LAYER1）的突变增强了对水分亏缺的敏感性。转录组分析和生化证据表明脱氢基因ZmDHN2是ZmOCL1的直接靶基因之一。ZmDHN2在玉米中的过表达通过调节气孔关闭、提高过氧化物酶活性和减少过氧化氢积累来获得抗旱性。筛选ZmOCL1的上游激酶，鉴定出丝裂原活化蛋白激酶（MAPK） ZmMPK5，该激酶可通过脱水激活。ZmMPK5磷酸化ZmOCL1的Ser283残基，并增加其与ZmDHN2启动子的结合亲和力，导致ZmDHN2的完全诱导。与野生型玉米相比，过表达ZmMPK5提高了玉米的耐旱性，ZmDHN2的转录水平提高，而敲除ZmMPK5导致玉米对干旱敏感，ZmDHN2的转录水平降低。我们的研究揭示了一个转录调控模块，其中ZmOCL1在被ZmMPK5磷酸化后促进ZmDHN2的表达，以应对干旱胁迫，最终导致更好的适应缺水。

The advancement of technology in recent decades has given us an unprecedented ability to observe the natural world. With modern sequencing and bioinformatics technologies, we can obtain more information about the microscopic world, and its interactions with the macroscopic world, than ever before. However, fungal studies that use meta'omic technologies have been sparse compared with bacterial and plant-focused studies. In this review, we highlight the ways that meta'omics can help to address pressing questions in belowground plant-fungal ecology, show consistencies that are emerging - and discrepancies that still exist - among analysis pipelines, and advocate for reporting standards that will allow meta'omic research to more fully benefit fungal ecology.

Leaf phosphorus (P) concentration has traditionally been assumed to increase from the equator to the poles. However, whether there exists a uniform or symmetrical latitudinal pattern across both hemispheres has never been examined due to variation in the geological histories, land-sea distribution, and climate of the hemispheres. We analyzed global latitudinal trends in woody plant leaf P concentrations across hemispheres to evaluate four hypotheses underlying these patterns. We show that leaf P concentration was significantly higher in the Northern Hemisphere than in the Southern Hemisphere, increasing with latitude in the former but decreasing in the latter. Key drivers of leaf P concentration differed between hemispheres: temperature dominated Northern Hemisphere variations, supporting the Temperature-Plant Physiology Hypothesis, while soil available P (indicative of substrate age) primarily influenced Southern Hemisphere trends, supporting the Soil Substrate Age Hypothesis. Temperature and precipitation play opposite roles in forming the leaf P latitudinal patterns in the two hemispheres. Our findings challenge the notion of a traditional latitudinal P gradient and emphasize incorporating hemisphere-specific climatic and edaphic drivers into forest productivity and global P-cycling models. Resolving these asymmetries will improve predictions of vegetation responses to environmental change and enhance Earth system model accuracy.

In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves. Seven populations (n ≥ 20 per site) were studied in the field and in a > 2-yr common-garden experiment. Leaf traits (mass per area, area, succulence, stomatal, and trichome densities) and thermal tolerance (T50 for heat and cold) were measured, and germination assays (10-35°C) quantified seed thermal performances. Multivariate analyses linked leaf and seed traits to elevation and local thermal conditions. Heat tolerance and leaf traits were maintained in the common garden, indicating strong canalization, whereas cold tolerance was highly plastic, decreasing by up to 17.9°C. Seeds from high elevations germinated faster, with higher cardinal temperatures and c. 230 fewer growing degree days than lowland seeds. Thermal niche differentiation in P. flammea arises from canalized heat resistance and plastic cold responses, coordinated across leaves and seeds. Considering thermal traits across life stages improves predictions of population resilience under climate warming.

Plants have evolved diverse defenses against herbivores, and some species produce juvenile hormone III (JH III) that disrupts insect growth and reproduction. While the insect JH III biosynthetic pathway is well-established, its occurrence and basis in plants remain unresolved. We investigated the molecular and biochemical basis of JH III biosynthesis in the model sedge Cyperus iria. Comparative genomics, expression profiling, metabolic analyses, and in vitro enzyme assays were combined with transient pathway reconstruction in Nicotiana benthamiana. Cyperus iria harbors members of the same enzyme families of four insect JH III pathway enzymes but lacks a canonical farnesoic acid methyltransferase (FAMT). A pair of SABATH methyltransferases was identified as functional FAMTs (CiFAMT) in C. iria. Functional validation in N. benthamiana transient assay demonstrated that CiFAMT can replace the insect farnesoic acid methyltransferase within an otherwise insect-based pathway, confirming its role in methyl farnesoate biosynthesis. Our results demonstrate that plants and insects have independently evolved the capacity to biosynthesize structurally identical JH III through recruitment of non-homologous enzymes. This provides compelling evidence for structural convergent evolution of a specialized metabolite with ecological implications for plant-insect interactions.
