In the second experiment, the effect of different concentrations of melatonin (50, 100, 300 and 500 µM) on the alleviation of detrimental effects of water stress was investigated in the highest level of drought stress (− 7 Bar PEG). The finding in the first experiment (drought stress applying) demonstrated that water deficit decreased length, fresh and dry weight of shoot and root, chlorophyll content and antioxidant enzyme activities, such as ascorbate peroxidase, catalase, superoxide dismutase and peroxidase, and also led to an increase in proline content. Also, melatonin treatment (especially 100 mM) improved photosynthetic performance by increase in net photosynthesis (P_N) and transpiration rate (E), reducing chlorophyll degradation but increasing the antioxidant enzyme activities. These results revealed that fenugreek tolerated water deficit by increasing the endogenous melatonin and trigonelline, as well as the general physiological responses.</p></div>","PeriodicalId":6973,"journal":{"name":"Acta Physiologiae Plantarum","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138947712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oregano (<i>Origanum vulgare</i> L.), a valuable herb of the Lamiaceae family, contains various types of biologically active constituents such as essential oils, tannins, resins, sterols, flavonoids, and phenolic glycosides. The present research was carried out to investigate the influence of salinity stress on some physiological and biochemical attributes and antioxidant responses in two oregano subspecies (ssp. <i>vulgare</i> and ssp. <i>gracile</i>). Salt treatments were applied using irrigation with different sodium chloride concentrations (0, 25, 50, and 100 mM NaCl). The results revealed a remarkable decline in relative water content (RWC) and photosynthetic pigments in both subspecies under NaCl stress. Total soluble sugars (TSS) decreased in plants exposed to severe salt stress (100 mM NaCl), whereas H₂O₂ production, electrolyte leakage (EL), malondialdehyde (MDA), and leaf proline contents increased in these plants compared to control plants. A positive relationship was found between H₂O₂ production with EL and MDA. Furthermore, salinity improved phenolic content, antioxidant capacity, and activity of superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) enzymes. The highest total flavonoid content (TFC) was achieved at 50 mM NaCl salinity, which increased by 19.33% compared to control plants. A positive relationship between the activity of phenylalanine ammonia-lyase (PAL) and TPC and TFC was observed. Analysis of phenolic compounds by HPLC showed that the amounts of gallic acid, caffeic acid, chlorogenic acid, and quercetin in ssp. <i>gracile</i> and caffeic acid, cinnamic acid, and quercetin in ssp. <i>vulgare</i> significantly increased with increasing salinity stress.

Non-photochemical quenching (NPQ), as a photoprotective mechanism, also plays an important role in different adversities. Although this mechanism is relatively understood, the relationship between ABA synthesis and NPQ induction under drought remains poorly defined. To understand the role of ABA in the mechanism underlying the photosynthetic response to drought, two rice cultivars with different chlorophyll contents were exposed to drought and exogenous ABA. Drought significantly stimulated the accumulation of endogenous ABA in leaf, and the application of exogenous ABA under drought further stimulated it through the up-regulated expression of the genes encoding 9′-<i>cis</i>-epoxycarotenoid dioxygenase. The application of exogenous ABA triggered higher NPQ under drought, especially in Zhefu802. The expression of <i>PsbS1</i> was significantly increased by drought, while the expression of <i>PsbS1</i> was further up-regulated by spraying ABA under drought. However, the high zeaxanthin content was not further up-regulated by spraying ABA under drought. These results indicated that ABA increased the expression of <i>PsbS1</i> and further triggered NPQ as a strategy to decrease the overexcitation of the photosynthetic apparatus in rice. This phenomenon was validated by slowing the decrease of the net photosynthetic rate under the application of exogenous ABA in the two rice cultivars. Except for the regulation of photoprotection, exogenous ABA significantly decreased the malondialdehyde level in Zhefu802 and the H₂O₂ level in Fgl. In conclusion, exogenous ABA significantly increases endogenous ABA and then triggers NPQ to mitigate the inhibition of photosynthesis in drought.</p></div>","PeriodicalId":6973,"journal":{"name":"Acta Physiologiae Plantarum","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138947053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to assess growth, yield components, nitrogen accumulation, NUE, and nitrate reductase activity in 60 cucumber genotypes under sufficient (NS) and deficient (ND) nitrogen conditions. Nitrogen deficiency caused reductions in growth and yield across all genotypes, although the severity varied. Nitrogen content was higher in all plant organs under NS compared to ND. NUE and its components nitrogen uptake efficiency (NUpE) and nitrogen utilization efficiency (NUtE) were significantly higher under ND versus NS. Line 57 exhibited the best NUE and yield under both NS and ND, and could be considered a nitrogen-efficient genotype. Based on NUE performance, lines were categorized as efficient, semi-efficient, low-efficient, and inefficient. Nitrate reductase activity was higher in leaves versus roots, and positively correlated with NUE, suggesting a relationship between enzyme activity and nitrogen uptake efficiency in roots. This study demonstrates genotype-specific responses to nitrogen availability in cucumber. The identification of genotypes efficient in NUE, such as line 57, can inform breeding efforts to improve nitrogen responsiveness. Characterizing nitrogen responsiveness across genotypes also allows for optimized, genotype-specific nitrogen management recommendations to be made, facilitating sustainable crop production.</p></div>","PeriodicalId":6973,"journal":{"name":"Acta Physiologiae Plantarum","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138743103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
