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. This study set as proof of concept to demonstrate that endophytes adapted to adverse environments can efficiently tweak non-host plant responses to abiotic stresses such as water deficit stress via physiological and molecular pathways, offering a huge opportunity for their deployment in sustainable agriculture.","PeriodicalId":20064,"journal":{"name":"Plant Molecular Biology","volume":"115 1","pages":"22"},"PeriodicalIF":3.9,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143009749","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}

However, the mechanism by which kiwifruit responds to T3SS remains unclear. To elucidate the molecular reaction of kiwifruit plants to Psa infection, M228 and mutant M228△hrcS strains were employed to inoculate Actinidia chinensis var. chinensis for performing comparative transcriptional and metabolomic analyses. Transcriptome analysis identified 973 differentially expressed genes (DEGs) related to flavonoid synthesis, pathogen interaction, and hormone signaling pathways during the critical period of Psa infection at 48 h post-inoculation. In the subsequent metabolomic analysis, flavonoid-related differential metabolites were significantly enriched after the loss of T3SS.Through multi-omics analysis, 22 differentially expressed genes related to flavonoid biosynthesis were identified. Finally, it was discovered that the transient overexpression of 3 genes significantly enhanced kiwifruit resistance to Psa. qRT-PCR analysis indicated that Ac4CL1, Ac4CL3 and AcHCT1 promote host resistance to disease, while Ac4CL3 negatively regulates host resistance to Psa. These findings enrich the plant immune regulation network involved in the interaction between kiwifruit and Psa, providing functional genes and directions with potential application for breeding kiwifruit resistance to canker disease.","PeriodicalId":20064,"journal":{"name":"Plant Molecular Biology","volume":"115 1","pages":"21"},"PeriodicalIF":3.9,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143009931","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}

Transcription factors (TFs) often act as regulatory hubs to regulate plant growth and responses to stress by integrating various biological pathways. 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. The regulation hub mediated various pathways, including pyruvate metabolism, glycolysis/gluconeogenesis, amino acid metabolism, and ubiquinone and other terpenoid-quinone biosynthesis.Our findings suggest that perturbation of a key biological pathway in S.miltiorrhiza has time-dependent effects on other biological processes.

Here, the SDS promoter, which is capable of specifically driving gene expression in microsporocytes, was employed to drive the expression of 5mARF17. The pSDS:5mARF17#3 transgenic line were male sterile. TEM revealed that sporopollenin substance was embedded in a thicker callose layer, which resulted in the complete loss of exine structure and pollen abortion in the pSDS:5mARF17#3 line. Consistently, RT-qPCR revealed an increase in the expression of several Cals genes in pSDS:5mARF17#3. EMSA assay demonstrated that ARF17 could bind to the promoter of Cals4 gene, which further suggest that ARF17 could regulate several Cals genes expression. It is notable that the expression of several exine formation-related genes increased significantly in pSDS:5mARF17#3.

Members of Brassicaceae family employ a \"lock and key\" mechanism involving stigmatic (sRALFs) and pollen RALFs (pRALFs) binding to FERONIA, a Catharanthus roseus receptor-like kinase 1-like (CrRLK1L) receptor, to establish a prezygotic hybridization barrier. 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. Using advanced structural modeling techniques and flexible peptide molecular docking, this study reveals that pRALFs and sRALFs bind to negatively charged pockets in FERONIA with varying binding affinities. Our study unveils the structural basis of this binding, shedding light on the molecular mechanism underlying hybridization barriers in Brassicaceae.","PeriodicalId":20064,"journal":{"name":"Plant Molecular Biology","volume":"115 1","pages":"17"},"PeriodicalIF":3.9,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142984495","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}

The evidence supports the important role of DAZ1 in GC shape partial morphogenesis. The C-terminus of DUO1 may regulate some target genes that affect GC body elongation.

Nucleotide-binding leucine-rich repeat (NLR) genes constitute the largest group of plant disease resistance genes, from which functional genes against diverse pathogens across various crops have been cloned. In this study, a comprehensive genome-wide analysis identified 346 NLR genes from D. alata, including one RNL and 345 CNLs.

The majority of NLR genes (91%) were located in multigene clusters, implying that tandem or proximal duplication was the primary driving force for NLR gene expansion in D. alata. Comparative analysis of Dioscoreaceae species revealed high variability and differential expansion patterns of NLR genes. In addition, transcriptome profiling of D. alata post-infection with C. gloeosporioides identified 12 differentially expressed NLR genes.

Hydrogen sulfide (H2S) is an ubiquitous gas signaling molecule, and its role in alleviating plant cold stress has become a research focus in recent years. This paper reviews for the first time the significant effect of H2S on improving plant cold resistance, which makes up for the gaps in the existing literature. In general, H2S improves plant tolerance to cold stress by activating antioxidant reaction and promoting the accumulation of metabolic substances such as chlorophyll, flavonoids, proline, sucrose and total soluble sugar in plants. Interestingly, H2S also interacts with nitric oxide (NO), auxin, jasmonic acid (JA), salicylic acid (SA), and ethylene (ETH) to alleviate cold stress. More importantly, in the process of alleviating cold stress with H2S, gene expression related to H2S synthesis, cold response and antioxidant is up-regulated or down-regulated, leading to the improvement of plant cold resistance. This paper also points out the problems existing in the current research and the potential of H2S in agricultural practice, and provides relevant theoretical references for future research in this field.","PeriodicalId":20064,"journal":{"name":"Plant Molecular Biology","volume":"115 1","pages":"12"},"PeriodicalIF":3.9,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142882487","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}
