Abstract ：
Genes that introgress between species can influence the evolutionary and ecological fate of recipients exposed to novel environments. However, key questions on the patterns and molecular mechanisms of introgression in perennial herbaceous plants, which enable distantly related invasive species to thrive in extreme habitats, remain largely unanswered. Here, we report unidirectional introgression from the local species Dendrobium huoshanense to the distantly related invasive species Dendrobium catenatum (Den-drobium officinale) in lithophytic habitats of eastern China. The introgressed regions, which comprise approximately 1% of the genome, contain genes that regulate responses to drought, cold, and metal-ion stresses. Notably, introgressed loci such as CDPK, HHP, PIF, BRI1, and FYshow distinct selection signatures and differential expression compared with their paralogs, each playing a distinct role in drought and cold-stress responses. In addition, CIPK23, PDR9, and HAM demonstrate differential expression relative to their paralogous genes and alleles within introgressed loci, indicating their potential involvement in responses to metal-ion stress. Introgression thus facilitates the colonization of arid, metal-enriched sedimentary habitats by D. catenatum. These findings enhance our understanding of Orchidaceae evolution and reveal the evolutionary role of unidirectional introgression in the adaptation of perennial herbaceous plants to extreme environments.

Abstract ：
Angraecum sesquipedale, also known as Darwin's orchid, possesses an exceptionally long nectar spur. Charles Darwin predicted the orchid to be pollinated by a hawkmoth with a correspondingly long proboscis, later identified as Xanthopan praedicta. In this plant-pollinator interaction, the A. sesquipedale flower emits a complex blend of scent compounds dominated by diurnally regulated oximes (R1R2C = N-OH) to attract crepuscular and nocturnal pollinators. The molecular mechanism of oxime biosynthesis remains unclear in orchids. Here, we present the chromosome-level genome of A. sesquipedale. The haploid genome size is 2.10 Gb and represents 19 pseudochromosomes. Cytochrome P450 encoding genes of the CYP79 family known to be involved in oxime biosynthesis in seed plants are not present in the A. sesquipedale genome nor the genomes of other members of the orchid family. Metabolomic analysis of the A. sesquipedale flower revealed a substantial release of oximes at dusk during the blooming stage. By integrating metabolomic and transcriptomic correlation approaches, flavin-containing monooxygenases (FMOs) encoded by six tandem-repeat genes in the A. sesquipedale genome are identified as catalyzing the formation of oximes present. Further in vitro and in vivo assays confirm the function of FMOs in the oxime biosynthesis. We designate these FMOs as orchid oxime synthases 1-6. The evolutionary aspects related to the CYP79 gene losses and neofunctionalization of FMO-catalyzed biosynthesis of oximes in Darwin's orchid provide new insights into the convergent evolution of biosynthetic pathways.

Abstract ：
Sucrose non-fermenting 1-related protein kinases (SnRKs) are crucial for modulating plant responses to abiotic stresses, linking metabolism with stress signaling pathways. Investigating the roles and stress responses of SnRKs in plants paves the way for developing stress-tolerant strategies in orchid species. Here, 362 SnRK members were identified from nine current orchid genomes, highlighting the conservation of these genes in evolution. Among these, 33 CeSnRKs were found across 20 chromosomes of C. ensifolium genome. Multiple duplication events increased the complexity of CeSnRKs during independent evolution. Moreover, distinct functional domains beyond the kinase domain differentiated the subfamilies. These multi-copy members existed tissue specific expressions falling into 6 main trends, especially CeSnRK1, CeCIPK9, CeCIPK23 displayed a strict floral expression. ABA-related elements were enriched in the promoters of CeSnRKs, and stress-related miRNA binding sites were identified on partial CeSnRKs. Consequently, most CeSnRKs exhibited up-regulated expression during ABA treatment. Several genes, such as CeSnRK2.1 and CeCIPK28 involved growth and development at different times and various tissues. The up-regulation of SnRK2.1, along with high expression of SnRK1 and CIPK27 under drought stress, and the differential expression patterns of CeSnRKs under cold stress, underscore the involvement of CeSnRK genes in different stress responses. Additionally, the diverse interactions of CeSnRKs with proteins highlighted a multifaceted functional network.These findings offer valuable insights for the future functional characterization formation of CeSnRKs and the adaptive evolution of genes in orchids.

Abstract ：
The GRF (Growth-Regulating Factor) gene family has indispensable regulatory functions in the morphological and physiological development of plants. Nonetheless, comprehensive investigations of GRF gene family members and their functional roles in Cymbidium goeringii, Cymbidium ensifolium, and Cymbidium sinense are still lacking. Therefore, the GRF gene family members in three Cymbidium species were systematically identified, and their expression profiles and potential biological functions were comprehensively evaluated in the study. The results provided evidence that eleven, eleven, and nine GRF genes were identified in C. goeringii, C. ensifolium, and C. sinense, respectively. These genes encode proteins considered as 153-584 amino acids and have been postulated to be located in the cell nucleus. The promoter contains cis-acting elements associated with hormone response regulation, tissue-specific expression, modulation of organismal growth and development, and environmental signal response. The analyses of gene architecture and motif composition demonstrated that introns and motifs within each evolutionary branch are highly similar, whereas significant differences exist between evolutionary branches. The results of chromosome localization and collinearity analysis showed that only a pair of segmental duplication genes was identified in C. goeringii. Moreover, transcriptome data and qRT-PCR results indicated that GRF genes are involved in various organs of C. goeringii. In conclusion, these findings may establish a foundation for theoretical inquiry into the future functional analysis of GRF genes in orchids.

Abstract ：
Anthracnose, caused by Colletotrichum gloeosporioides (Cog), severely constrains the Cymbidium ensifolium industry. To investigate the molecular underpinnings of resistance and the host-pathogen interaction strategies between C. ensifolium and Cog, we employed transcriptomics and metabolomics to compare the post-infection responses of the Cog-resistant (RV) and Cog-susceptible (SV) C. ensifolium varieties. Our integrated analysis reveals that resistance to Cog in C. ensifolium is partially mediated by the targeted accumulation of phenylpropane pathway metabolites, especially those involved in flavone and flavonol biosynthesis. Metabolites including rutin, lonicerin, nicotiflorin, apiin, and coniferin exhibited highly significant accumulation in the RV. The massive accumulation of various flavonoids in the SV was consistent with the gene expression trends in the phenylpropanoid pathway, a pattern indicative of an antioxidant stress response driven by stress reprogramming. A similar phenomenon was also observed in the core reactive oxygen species (ROS) scavenging pathway, glutathione metabolism. This ultimately results in two distinct outcomes: a potent, antifungal defense reprogramming in the RV versus an antioxidant-focused stress reprogramming in the SV. The observed trade-offs between antifungal and antioxidant activities in these varieties provide novel insights into the multilevel regulatory networks governing plant-pathogen interactions. Our study illuminates this sophisticated defense strategy of C. ensifolium against Cog, identifying core metabolites and pathways that now serve as a guide for targeted resistance breeding programs.

Abstract ：
Given the rising demand for natural pigments and functional compounds, the flowers of spring orchid (Cymbidium goeringii), which are rich in bioactive anthocyanins, are a promising yet underutilized resource. Nevertheless, the metabolic regulatory mechanism that mediates the accumulation of anthocyanins in this species is still largely unknown. In this study, the physiological, comparative transcriptomics, and bioinformatics analyses were integrated to evaluate the total anthocyanin (TA) content and transcriptomic profiles of three floral tissues of the dark purple flowers from C. goeringii 'Hei Ban' (S: sepal, P: petal, and L: labellum) at three developmental stages (PB: bud stage, PH: half blooming stage, and PF: full blooming stage). The highest TA content in sepals was detected at PH [3.55 mg center dot g-1 fresh weight (FW)] and in petals at PB (3.65 mg center dot g-1 FW), highlighting their potential as a promising natural source for anthocyanin-based functional products. Subsequently, specific structural genes and transcription factors (TFs) potentially regulating flower color of C. goeringii were investigated based on the Weighted gene co-expression network analysis (WGCNA), including key structural genes [especially dihydrofiavonol 4-reductase (DFR)] and TFs [MYB (myeloblastosis-related) and WRKY (WRKY domain-containing)]. During flower development, DFR (GL05021 and GL06597) expression levels were strongly positively correlated with MYB (GL08332) and WRKY (GL32178), which are the candidate genes potentially associated with anthocyanin accumulation. Further, the labellum color was potentially affected by carotenoid biosynthesis. These results provide valuable insights for the efficient utilization and value enhancement of spring orchid and other ornamental orchids in natural pigment extraction and functional products development.
