We aimed to determine the role of LA in induction of the antioxidant system at lower reactive oxygen species (ROS), ascorbate (ASC) and glutathione (GSH) levels in osmotic-stressed maize (<i>Zea mays</i> L.). For this purpose, ROS, GSH and ASC contents were decreased using N,N'‑dimethylthiourea (DMTU), L-buthionine sulfoximine (BSO) and acriflavine (AF), respectively. Pots containing 21-day-old seedlings were divided into nine groups consisting of a non-stressed group; polyethylene glycol₆₀₀₀ (PEG)-induced osmotic stress (PEG) group, LA, DMTU, BSO and AF treatment groups; and DMTU, BSO, and AF-combined LA treatment groups under osmotic stress. ROS contents and membrane damage after the DMTU, BSO, and AF-combined LA treatments were lower than those after the DMTU, BSO, and AF treatments, respectively. Moreover, the LA treatments in combination with DMTU, BSO and AF increased dry weight, activities of antioxidant enzymes (superoxide dismutase, catalase, ascorbate peroxidase, glutathione reductase, monodehydroascorbate reductase and dehydroascorbate reductase), and contents of GSH, ASC, and LA compared to the DMTU, BSO and AF treatments. Additionally, the relative expression levels of <i>SUPEROXIDE DISMUTASE</i>, <i>CATALASE1</i> and <i>ASCORBATE PEROXIDASE1</i> genes were consistent with the findings for their related antioxidant enzyme activities. These results indicated that LA could adjust ROS level and maintain stimulation of the antioxidant system at lower ROS, GSH, and ASC levels in osmotic stressed maize. Furthermore, LA may play a signaling role and assume the function of ASC and GSH in maize under PEG-induced osmotic stress.</p>","PeriodicalId":21477,"journal":{"name":"Russian Journal of Plant Physiology","volume":"24 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141513116","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}

Phenol treatment increased the content of carotenoids, carbohydrates, dry biomass and protein in the red cells, especially at lower concentrations. Treatment with high-concentration phenol had a significant effect on xanthophylls, while pretreatment with lower concentrations of phenol showed parallel effects.

Therefore, in this study, we investigated the effect of chitosan and salicylic acid on morphological and physiological parameters and fatty acids content under drought stress. The first factor was drought stress levels (Field capacity (F.C), 70% of F.C and 40% of F.C), the second factor was elicitors (control (C), 0.5 mM salicylic acid, 1 mM salicylic acid, 100 mg/L chitosan and 200 mg/L chitosan) and the third factor was sampling times (3, 7, 14, 21 days after drought stress) with three replications. According to the results, comparing the three drought stress levels, severe stress treatment (40% F.C) significantly reduced the growth traits of milk thistle. Foliar application of chitosan and salicylic acid significantly compensated for the reduction of growth traits in plants under drought stress, in which chitosan frequently had higher growth and tolerance than salicylic acid. The role of elicitors in reducing the stress negative effects on plant growth is often due to stimulating chlorophylls, reducing hydrogen peroxide levels, and production of antioxidant enzymes. In our findings, chitosan demonstrated an increase of 28.4, 10, and 8% in relative water content (RWC), chlorophylls, and catalase activity, respectively, compared to the control. Similarly, salicylic acid revealed an increase of 29.3, 4, and 2% in the same parameters compared to the control. Besides, hydrogen peroxide in plants treated with chitosan and salicylic acid decreased by 20 and 15%, respectively. Besides, drought stress significantly reduced the predominant fatty acids in the seed, which elicitor application reduced the effect of stress slightly. Chitosan had a higher effect than salicylic acid in increasing fatty acids content. Foliar application of CHT and SA increased plant tolerance under drought stress.

In the present study, the stress tolerance of transgenic line (Tr-3) and nontransgenic plants of bread wheat cv. Saratovskaya-60 was studied. Transgenic line Tr-3 overexpresses <i>AtOPR3</i> (<i>12-OXOPHYTODIENOATE REDUCTASE 3</i>) gene from <i>A. thaliana</i> encoding the jasmonate biosynthesis enzyme 12-oxophytodienoate reductase. In spite of the high expression level of <i>AtOPR3</i>, the content of jasmonic acid and its conjugate with isoleucine in intact leaves of the transgenic plants remained unchanged. Furthermore, in the mechanically wounded leaves, the content of jasmonic acid in the transgenic line Tr-3 was even lower than in nontransgenic Saratovskaya-60, while the levels of 12-oxophytodienoic acid and jasmonoil-isoleucine did not differ. In the transgenic plants, the stress-induced expression of the endogenous jasmotate-regulated allene oxide synthase gene was, however, higher than in the nontransgenic control. The transgenic wheat plants were more tolerant to infection by necrotrophic fungus <i>Botrytis cinerea</i> and to osmotic stress caused by polyethylene glycol applied to germinating seeds. The <i>Botrytis-</i>inoculated leaves of the transgenic line Tr-3 manifested higher activity of antioxidant enzyme catalase than inoculated leaves of nontransgenic plants.
