Over the past decade, research has revealed ribosome subgroups respond to adverse conditions, suggesting that this tight coordination may be grounded in the induction of ribosome variants resulting in differential translation outcomes. Furthermore, an increasing snumber of studies on plant ribosomes have made it possible to explore the stress-regulated expression pattern of ribosomal protein large subunit (RPL) and ribosomal protein small subunit (RPS) genes. In this perspective, we reviewed the literature linking ribosome heterogeneity to plants' abiotic and biotic stress responses to offer an overview on the expression and biological function of ribosomal components including specialized translation of individual transcripts and its implications for the regulation and expression of important gene regulatory networks, along with phenotypic analysis in ribosomal gene mutations in physiologic and pathologic processes.

High soil pH severely impacts plant growth and productivity, yet the transcriptomic changes and microbial dynamics underlying stress adaptation in garden pea (Pisum sativum ssp. hortense) remain unclear. This study demonstrates that high soil pH leads to stunted growth, reduced biomass, impaired photosynthesis, and nutrient status in garden pea. Further, disruption in key nitrogen-fixing bacteria (Rhizobium indicum, R. leguminosarum, and R. redzepovicii), along with the downregulation of NifA and NifD genes and upregulation of NifH in nodules highlights the critical role of micronutrient balance in legume-microbe symbiosis and a compensatory response to maintain nitrogen status. RNA seq analysis revealed extensive transcriptional reprogramming in roots, characterized by the upregulation of oxidative stress response genes (e.g., oxidoreductase and glutathione transferase activities, metal ion transporters) and the downregulation of genes related to ammonia-lyase activity and ion binding, reflecting broader disruptions in nutrient homeostasis. KEGG pathway analysis identified enrichment of MAPK signaling pathway, likely interacting with other pathways associated with stress tolerance, metabolic adjustment, and structural reorganization as part of adaptive responses to high pH. Root microbiome analysis showed significant enrichment of Variovorax, Shinella, and Chaetomium, suggesting host-driven recruitment under high pH stress. Stable genera, such as Pseudomonas, Novosphingobium, Mycobacterium, Herbaspirillum, and Paecilomyces, displayed resilience to stress conditions, potentially forming core microbiome components for adaptation to high pH. In a targeted study, inoculation of plants with an enriched microbiome, particularly C. globosum, under high pH conditions improved growth parameters and increased the abundance of Stenotrophomonas and Pseudomonas in the roots. It suggests that these bacterial genera may act as helper microbes to C. globosum, collectively promoting stress resilience in pea plants suffering from high pH. These findings provide a foundation for microbiome-aided breeding programs and the development of microbial consortia to enhance the adaptation of pea plants to high pH conditions.</p>","PeriodicalId":20177,"journal":{"name":"Planta","volume":"261 4","pages":"83"},"PeriodicalIF":3.6,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143586641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Black pepper (Piper nigrum L.) is renowned as a versatile seasoning, offers numerous health benefits, and possesses historical significance in the global spice trade. Variations in advantageous agronomic traits among diverse black pepper genotypes underscore the potential value of understanding their underlying genetic regulation. One emerging genetic component of interest is copy number variation (CNV), which represents a significant source of intra-varietal genetic diversity by altering the dosage of DNA segments, thereby influencing phenotypic characteristics. In this study, we conducted genome-wide resequencing of thirty-nine black pepper germplasm accessions to identify high-confidence CNVs and explore their functional impact on agronomic traits. Our analysis identified a total of 159,390 CNVs and delineated 11,360 CNV regions (CNVRs) with an average length of 87,106 base pairs. Among these, we observed 82,027 deletion and 77,363 duplication events across the 26 chromosomes of black pepper. Notably, deletions were more frequent than duplications. Enrichment analysis of genes harbored within CNVRs revealed their involvement primarily in piperine biosynthesis and immune response pathways. Principal component analysis demonstrated varietal differentiation and highlighted intra-varietal evolutionary linkage among tested genotypes, suggesting that CNVRs play a significant role in shaping the evolution of elite black pepper genotypes. For instance, genotype IISR-Malabar Excel exhibited the highest number of deletions, whereas genotype Acc:7211 showed the most duplications. Chromosome 1 exhibited the highest frequency of deletions, while chromosome 3 showed the highest frequency of duplications. While the overall number of CNVRs did not significantly differ among genotypes, 33 CNVRs contained genes crucial for phenylpropanoid biosynthesis, with 14 genes undergoing deletions and 19 genes showing duplications. Additionally, we developed a web resource BPCNVDb, which could be retrieved ( https://bpcnvdb.daasbioinfromaticsteam.in/index.php ) to facilitate access to genotype-specific CNVs and CNVRs, aiming to enhance breeding efforts in black pepper.</p>","PeriodicalId":20177,"journal":{"name":"Planta","volume":"261 4","pages":"81"},"PeriodicalIF":3.6,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143586634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 10-bp deletion in its promoter enhances gene expression in purple plants, likely by disrupting MYB transcription factor binding, leading to anthocyanin accumulation. Leaf color is a critical trait influencing the commercial and nutritional value of leafy vegetables, with purple-leafed varieties prized for their high anthocyanin content. In this study, we investigated the genetic basis of purple leaf coloration in non-heading Chinese cabbage (Brassica rapa). Using a recombinant inbred line (RIL) population derived from a cross between purple-leafed S45P and green-leafed S45G lines, bulked segregant analysis sequencing (BSA-seq) and fine mapping were performed. The analysis identified BraP2, a locus on chromosome A03 associated with purple leaf coloration. Within the 65.31 kb candidate region, BraA03g059660.3C, encoding chalcone isomerase (CHI), was identified as the strongest candidate gene. Quantitative real-time PCR (qRT-PCR) revealed significantly higher expression of BraA03g059660.3C in purple-leafed S45P plants compared to green-leafed S45G plants. Further sequence analysis uncovered a 10-bp deletion in the promoter region of BraA03g059660.3C in S45P plants. This deletion likely disrupts a MYB transcription factor binding site, enhancing gene expression and promoting anthocyanin accumulation. Our findings demonstrate that BraA03g059660.3C plays a pivotal role in controlling purple leaf coloration in non-heading Chinese cabbage.
