Northern corn leaf blight (NCLB) is one of the most important foliar disease in maize, which leads to serious yield losses. It is necessary to identify resistance genes in order to control NCLB. Mitogen-activated protein kinase (MAPK) cascades play important roles in plant defense reactions. Ethylene-response factor (ERF) is involved in plant disease resistance in maize through phosphorylation by MAPK signaling pathway. Here, we found that ZmMPK6-1 positively regulates maize resistance against E. turcicum through enhancing the expression of defense-related genes and enzyme activities. Moreover, ZmMPK6-1 can interact with ZmERF061 which enhanced the transcriptional activation activity of ZmERF061. Taken together, our findings indicated that ZmMPK6-1 would act through improving ZmERF061 transcriptional activation activity to induce defensin gene expression in regulating the maize resistance against E. turcicum. These results revealed the molecular mechanism of ZmMPK6-1-ZmERF061 signaling pathway in response to E. turcicum, which is useful to maize E. turcicum resistance breeding.

Hemerocallis citrina Baroni (daylily) is an important cash crop in many regions of China. Daylily rust caused by Puccinia hemerocallidis (Ph) is a major disease in H. citrina. Rust infection on the leaves of two resistant and susceptible varieties of H. citrina was examined. Transcriptome sequencing and defense enzyme activity were used to analyze the differential expression of related genes after 0, 72, 144, 192, and 288 h, to reveal the response mechanism of H. citrina to rust infection and screen-related resistance genes. The results suggested that 72 h after Ph infection was the key time point for determining differences between resistant and susceptible varieties. DEGs were significantly enriched in phenylpropanoid biosynthesis, plant–pathogen interaction, plant hormone signal transduction, and the MAPK signaling pathway. TFs WRKY33 and CYP98A are key genes closely related to the disease-resistance response of H. citrina. This study is the first large-scale transcriptomic analysis of H. citrina.

In agricultural production, intercropping is a widely used system with many benefits. Lupin (Lupinus angustifolius L.) is a legume that contains a large variety of plant secondary metabolites, which have multiple functions in the plant, e.g. signalling, nodulation and stress response. An untargeted metabolomics approach was applied to investigate how the metabolome of lupin was affected by intercropped barley (Hordeum vulgare L.). The only primary metabolite of lupin affected by intercropping was tryptophan. Several secondary metabolites were affected by intercropping in lupin, and five flavonoids were annotated hereof. The flavonoid levels were increased, and tryptophan levels decreased in lupin when intercropped. Two flavonoids are prenylated, and prenylated flavonoids are believed to play a role in the plant’s stress response. Furthermore, flavonoids are involved in plant defence and the nodulation process. Thus the present flavonoids may affect regulation of lupin N2-fixation activity.

ABSTRACT This study investigates the impact of priming on the resistance of tomato plants to the potato aphid Macrosiphum euphorbiae, focusing on the role of glandular trichomes. Glandular trichomes are specific hairs that provide protection to tomato plants against herbivorous insects. The experimental priming conducted in this study revealed that prior infestation by Spodoptera littoralis caterpillars increased the plant's resistance against M. euphorbiae, pointing at the jasmonic acid (JA) signaling pathway in regulating this plant-aphid interaction. Glandular trichomes type IV were effective against aphids regardless of the previous infestation. Using JA-deficient tomato (spr2), we observed that M. euphorbiae multiplication increased, while the number of aphids on salicylic -deficient NahG plants was lower than in the wildtype Moneymaker. These findings emphasize the crucial role of the JA signaling pathway in tomato plant resistance to aphids and the importance of glandular trichomes to enhance plant defences against pests.

Legumes can contribute to emissions of the potent greenhouse gas nitrous oxide (N 2 O) directly by some rhizobia species that are able to denitrify under free-living conditions and in symbiotic association with the plant. In this study, the capacity of Phaseolus vulgaris - Rhizobium etli symbiosis to emit N 2 O in response to nitrate (NO 3) has been demonstrated for the fi rst time. We found that bacteroidal assimilatory nitrate reductase (NarB) as well as nitrite reductase (NirK) and nitric oxide reductase (cNor) denitrifying enzymes contribute to nitric oxide (NO) and N 2 O formation in nodules. We also show that R. etli NarK is involved in NO 2-extrusion and links NO 3-reduction by NarB in the cytoplasm with NirK and cNor denitri fi cation activities in the periplasm. The knowledge generated in this work will be instrumental for exploring strategies and sustainable practices in agricultural soil management to increase legume crop yield and mitigate greenhouse gas emissions

As plants are an essential component of sustainable life support systems, long-duration space missions will require a sophisticated understanding of plant adaptations to spaceflight and microgravity. For many years, transcriptional profiling of steady state mRNA abundances has been used as measure of plant adaptations to the space environment. However, measured changes in transcript abundances are often not reflected in corresponding changes in the proteome due regulatory processes governing translation. Translating ribosome affinity purification (TRAP) is a technique which selectively targets ribosome bound mRNAs for isolation and downstream sequencing. Comparing profiles of ribosome associated mRNAs with total mRNAs provides insight into the translatome and may more accurately inform on the cellular responses to the spaceflight environment. Toward that goal, this work describes a methodology developed ahead of the APEx-07 flight mission.

ABSTRACT The allelopathic effect of Callistemon viminalis’s leaf extracts on seed germination and growth of Triticum aestivum and Cicer arietinum, as well as associated weeds (Anagallis arvensis, Poa annua, Lepidium didymium, and Vicia sativa), was studied. Different concentrations (2–10%) of aqueous extracts were used, and physiological parameters were measured. Higher concentrations (6–10%) significantly inhibited the germination and growth of wheat and chickpea. In pot assay, the extract did not affect shoot length, dry plant mass, chlorophyll, carotenoid, proline, protein content, stomatal conductance, photosynthetic and transpiration rate, and antioxidant enzymes in crop and various parameters of soil properties in comparison to the control. Both crops grew significantly at lower concentrations. This study suggests that extract of C. viminalis can inhibit the growth of A. arvensis and V. sativa without affecting germination, photosynthetic and biochemical properties of C. arietinum and T. aestivum, and soil properties, making it a potential candidate for bioherbicide development.

ABSTRACT The space environment is extreme for plants growth and survival as gravity (gravitropism modification, water distribution), radiations (mutations enhancers), light spectrum regime and temperature are not optimal. Photosynthetic microorganisms are a foreseen solution for supporting plant development, growth, and stress tolerance in closed environments, like those designed for space colonisation. Indeed, photosynthetic microorganisms are known as secondary metabolites producers (exopolysaccharides, indole alkaloids, fertilisers) able to impact plant stimulation. Studying their abilities, application methodologies and best strains for space agriculture may lead to developing a sustainable and efficient approach for food production. Furthermore, as these microorganisms could also be used to produce oxygen and recycle waste materials increasing their interest in closed loop systems is undeniable. In this review we provide an overview of the current state of knowledge about existing biostimulants, their effects and applications, and the potential brought by photosynthetic microorganisms for life in closed environments. Highlights Cyanobacteria's and microalgae's secondary metabolites can act as biostimulants for vascular plants when applied to the roots or the leaves. Production of secondary metabolites in cyanobacteria can be enhanced in stressful environments. Cyanobacteria can survive space-like stress by sur-producing secondary metabolites giving an advantage for space farming as a source of biostimulant compounds.

ABSTRACT Copper oxide nanoparticles (CuO NPs) are a type of nanomaterial with unique physical and chemical properties that make them useful in various applications. CuO NPs have been studied for their potential agricultural applications, where they can have both positive and negative effects on plants, depending on factors such as concentration and duration of exposure. CuO NPs have been shown to improve plant growth and development by enhancing photosynthesis, nutrient uptake, and root growth. However, high concentrations of CuO NPs can cause oxidative stress and damage to plant cells, resulting in reduced growth and yield. Furthermore, these NPs can be taken up by plants and accumulate in various plant tissues, raising concerns about their potential impact on human health if ingested via the food chain. Further research is needed to determine the safe and effective application method and optimal concentration of CuO NPs in agriculture. Highlights CuO NPs can benefit or harm plants, based on concentration and exposure time. Monocots are more negatively affected by CuO NPs, dicots show diverse response. CuO NPs impact plants based on species, concentration, and application. More research needed to understand CuO NPs’ impact on plant growth and health. GRAPHICAL ABSTRACT

ABSTRACT The use of biological control agents (BCAs) to cope with diseases has received considerable attention owing to its high efficiency and environmental safety. The aim of our study was to investigate the potential role of Pseudomonas mediterranea pretreatment in the response of lemon [Citrus limon (L.) Burm. f.] against mal secco, which is a devastating citrus disease caused by the fungus Plenodomus tracheiphilus. RNAseq analysis revealed that the fungus induced marked reprogramming of the transcriptome, but P. mediterranea pretreatment strongly reduced lemon leaf transcriptome modifications and limited the amount of fungal DNA inside the plant tissue. Furthermore, P. mediterranea prevented the downregulation of the genes involved in effector-triggered immunity (ETI) and the deregulation of genes involved in the biosynthesis and perception of the main phytohormones. To the best of our knowledge, this work represents the first report on the analysis of the P. tracheiphilus-lemon plant-BCA interaction at the molecular level.

To the best of our knowledge, this work represents the first report on the analysis of the P. tracheiphilus-lemon plant-BCA interaction at the molecular level.","PeriodicalId":16830,"journal":{"name":"Journal of Plant Interactions","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2023-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47641647","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}
