This study identified 45 members of the SQUAMOSA-PROMOTER BINDING PROTEIN LIKE (SPL) gene family in the genome of Z. armatum. Phylogenetic and collinearity analyzes demonstrated a close relationship between ZaSPLs and ZbSPLs from B subgenomes of Zanthoxylum bungeanum. Our miRNA sequencing revealed a high degree of conservation of miR156a within Z. armatum, with the za-miR156a sequence identical to miR156-5p in Arabidopsis thaliana and Citrus sinensis. Of the 45 genes identified by ZaSPLs, 21 were targeted by za-miR156a, transient co-expression experiments in N. benthamiana demonstrated the targeting relationship between za-miR156 and ZaSPL21. Furthermore, RNA-seq and qRT-PCR analysis revealed that ZaSPL genes exhibited elevated expression levels in juvenile tissues of Z. armatum. The expression of nine representative ZaSPL genes were upregulated under polyethylene glycol (PEG) and abscisic acid (ABA). Overexpression of ZaSPL21 delayed the germination of transgenic tobacco and facilitated the flowering process in transgenic N. benthamiana. Significant up-regulation in the expression levels of flowering-related genes such as NbFT1, NbPIP2;1, NbTCP1, NbCOL1, NbGI2, NbGAI1, NbCKX2, and NbARR4 was observed in transgenic plants, suggesting that ZaSPL21 may stimulate plant flowering by regulation of these genes. Furthermore, ZaSPL21 also increased the germination speed of transgenic tobacco seeds during drought and salt stress conditions, and improved the salt tolerance of transgenic seedlings. In conclusion, our study contributes to understanding the functional analysis of the SPL gene family in Z. armatum and emphasizes the crucial role of ZaSPL21 in improving tolerance to salt and promoting flowering. The results offer potential strategies for the further utilization of these genes to improve the salt tolerance of Z. armatum.</p>","PeriodicalId":20064,"journal":{"name":"Plant Molecular Biology","volume":"115 1","pages":"23"},"PeriodicalIF":3.9,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143009819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To counteract this issue, a hydroponic study was conducted to explore low N stress (0.1 mM NO₃^-) and normal (5.0 mM NO₃^-) effects on the morpho-physiological and molecular attributes of peanut seedlings. Low-N stress significantly decreased peanut plant height, leaf surface area, total root length, and primary root length after 10 days of treatment. Meanwhile, glutamate dehydrogenase, glutamine oxoglutarate aminotransferase activities, chlorophyll, and soluble protein contents were substantially decreased. Impairment in these parameters further suppressed photochemical efficiency (Fv/Fm), and chlorophyll fluorescence parameters (PI_ABS), under low-N stress. Transcriptome sequencing analysis showed a total of 2139 DEGs were identified between the two treatments. KEGG enrichment annotation analysis of DEGs revealed that 119 DEGs related to 10 pathways, including N assimilation, photosynthesis, starch, and sucrose degradation, which may respond to low-N stress in peanuts.

Naturally, microbial consortia partner up to boost plant growth and constitute a diversified ecosystem against abiotic stresses. Despite this, little is known pertaining to the interplay between endophytic microbes which release phytohormones and stimulate plant development in stressed environments. In a lab study, we demonstrated that an endophyte isolated from the Kargil region of India, a Fusarium equiseti strain K23-FE, colonizes the maize hybrid MAH 14 - 5, promoting its growth and conferring polyethylene glycol (PEG)-induced osmotic stress tolerance. To unravel the molecular mechanism, maize seedlings inoculated with endophyte were subjected to comparative transcriptomic analysis. In response to osmotic stress, genes associated with metabolic, photosynthesis, secondary metabolites, and terpene biosynthesis pathways were highly upregulated in endophyte enriched maize seedlings. Further, in a greenhouse experiment, maize plants inoculated with fungal endophyte showed higher relative leaf water content, chlorophyll content, and antioxidant enzyme activity such as polyphenol oxidase (PPO) and catalase (CAT) under 50% field capacity conditions. Osmoprotectant like proline were higher and malondialdehyde content was reduced in colonized plants.

Despite extensive studies on TFs functions in various plant species, our understanding of the details of TFs regulation remains limited. In this study, clonal seedlings of Salvia miltiorrhiza were exposed to specific inhibitors for 12 h. Time-series transcriptome data, sampled hourly, were used to construct co-expression networks and gene regulatory networks (GRNs). Transcriptome dynamic analysis was utilized to capture the gene expression dynamics of various biological processes and decipher the potential molecular mechanisms that regulate these processes. The perturbation results showed the growth and development processes of S.miltiorrhiza were primarily affected at the early stage, whereas stress response-related biological processes were mainly influenced at the later stage. And there was a correlation between the series of key differentially expressed genes in terpenoid biosynthesis pathways and the topological distribution of these pathways. Furthermore, the GRNs based on TFs indicate that TFs play a crucial role in connecting various biological processes. In the cytoplasmic lysate gene regulatory module, SmWRKY48-SmTCP4-SmWRKY28 constituted a regulation hub regulating S.miltiorrhiza responses to perturbation of the MVA pathway.

In the absence of compatible pRALFs, sRALFs bind to FERONIA, inducing a lock state for pollen tube penetration. Conversely, compatible pRALFs act as a key, facilitating successful fertilization. Competing pRALFs reduce the sRALFs binding to FERONIA in a dose-dependent manner, enabling pollen tube penetration. Despite its crucial role in Brassicaceae hybridization, the structural basis of this binding remains elusive owing to the highly flexible nature of RALF peptides.
