Herein, we investigated the effects of Cu and Zn stress on the photosynthesis and tolerance mechanism of alfalfa plants to ROS using fluorescence and biochemical methods. The results showed that Cu stress significantly reduced the chlorophyll content of the leaves, while Zn stress only reduced the Chl a content. The F v/F m decreased significantly under Cu stress but was not affected by Zn treatment. However, the PI ABS of the leaves were sensitive to Cu and Zn stress. Both Cu and Zn stress resulted in the weakening of the ability of PQ library to accept electrons, the damage of OEC and the inhibition of the electron transfer from QA - to QB. Moreover, Cu stress also dissociated the thylakoids of leaves, but Zn stress did not significantly damage it. In Cu and Zn stressed leaves, the reduction of RC/CS m significantly increased the ABS/RC and TR o/RC values. When the stress intensified, the value of DI o/RC increased indicated a plant self-protection mechanism that eliminates excess energy in the PSII reaction center and increases the energy for heat dissipation per unit reaction center. Cu stress significantly increased the O2 - production rate, H2O2 content, and MDA accumulation in the leaves. However, Zn stress exhibited a minimal effect on the ROS production and oxidative damage in the alfalfa leaves but increased the O2 - production rate at the concentration of 800 μmol·L−1. Cu stress increased the activities of SOD, POD, CAT, APX, and GPX in the leaves; however, leaves adapts to Zn stress by enhancing the activities of SOD and GPX. Thus under Cu stress, the degree of photoinhibition and oxidative damage in alfalfa leaves were significantly higher than under Zn stress.","PeriodicalId":16830,"journal":{"name":"Journal of Plant Interactions","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60093788","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}

The main concern of this work was to assess the phenotypical, physiological, and molecular responses of five teosinte (Zea mexicana Schrad L.) genotypes (Ba, Gm1, Gm2, Gm3 and Gm4). In a two-season (2020 and 2021) field experiment, fifteen-day-old teosinte plants were subjected to well-watered (15-day watering frequency) as a control, moderate drought (25-day watering frequency), and extreme drought (35-day watering frequency) treatments. Drought negatively affected growth, yield, chlorophyll, and POD activity of all genotypes, but promoted soluble sugars and proteins, osmoregulatory molecules (glycinebetaine, amino acids, and proline), non-enzymatic antioxidants (phenols, flavonoids, and alkaloids), and SOD activity. Furthermore, long-term water stress upregulated MOCOS, Rad17, NCED1, CAT1, and P5CS genes expression, with Gm3 and Gm4 being the most drought-tolerant genotypes. These findings could be employed in breeding programs to develop tolerant genotypes to address the challenges posed by climate changes like drought.","PeriodicalId":16830,"journal":{"name":"Journal of Plant Interactions","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41897727","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}

A Klebsiella sp. strain San01 isolated from sweet potato roots exhibited diverse plant-growth-promoting activities, including indole acetic acid production, ammonia production, and phosphate solubilization. San01 inoculation significantly increased the growth characteristics of sweet potato. Moreover, the sweet potato inoculated with San01 resulted in the alleviation of drought and salinity stresses. In comparison with the non-inoculated plants, the wilting symptom and the inhibition of photochemical response were significantly diminished in San01-inoculated plants under stress conditions. In the presence of San01, the enhancement of 2,2-diphenyl-1-picrylhydrazyl radical scavenging ability and elevated activities of ascorbate peroxidase and superoxide dismutase were observed to combat the oxidative stress in sweet potato. Further investigation showed that the San01 inoculation enhanced the expression of the IbLEA gene in sweet potato under salinity and drought. These results confer a promising biotechnological approach through San01 interaction to develop stress-tolerant sweet potato plants.","PeriodicalId":16830,"journal":{"name":"Journal of Plant Interactions","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43717342","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}

To understand its biosynthesis and accumulation, a comparative expression analysis of flavonoid biosynthetic genes encoding enzymes responsible for synthesizing the main structure of flavonoids has been conducted in two differentially performing peanut varieties (PG 1247 and Bari 2011) in response to photoperiod and water availability. Transcript profiling of flavonoid biosynthetic genes indicated time-dependent expression of genes except for AhFLS in selected varieties in response to photoperiod variation. Many genes depicted a low degree of variation within varieties and water-deficient treatments. However, AhANS showed the highest variation for stress duration and varieties. In conclusion, this study has characterized the role of flavonoid biosynthesis in peanuts in response to photoperiod and water availability. Moreover, correlation analysis unraveled the coordination among the expression of flavonoid biosynthetic genes.","PeriodicalId":16830,"journal":{"name":"Journal of Plant Interactions","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47343644","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}

Most species of Psylloidea are confined to the tropics. They occur as gall-inducing, free-living, and lerp-forming taxa. Lifecycles and generations of gall-inducing Psylloidea vary in temperate and tropical worlds. The Triozidae, Aphalaridae, and Calophyidae include several taxa that induce galls of diverse morphologies, from simple pits and leaf-margin rolls to complex pouches and of two-tier structures. The feeding mechanism and nutritional physiology of the gall-inducing taxa of the Psylloidea differ from those of the free-living and lerp-forming species. A majority of the gall-inducing Psylloidea are associated with the dicotyledons and a small number with the monocotyledons. The gall-inducing Psylloidea are specific to certain plants. Their host specificity is regulated by specific lipids and sterols. The gall-inducing Psylloidea show conservative behavior in terms of geographical distribution. Although the life histories of several gall-inducing Psylloidea are known today, aspects explaining their association with host plants are little known. Details of nutritional physiology of gall-inducing Psylloidea are less known presently compared with that of the free-living species. A better understanding of the association and level of relationship between gall-inducing Psylloidea and their host plants is necessary.","PeriodicalId":16830,"journal":{"name":"Journal of Plant Interactions","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47538934","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}

Its interaction with the plant triggers resistance responses by the activation of Induced Systemic Resistance mediated by Jasmonic acid and Ethylene and/or Systemic Acquired Resistance, which involves Salicylic acid, with the consequent control of a wide range of plant parasites. However, the benefit they can confer to plants may be reduced or nullified by environmental conditions or fungal ecological fitness. A novel approach to enhance their effectiveness in plant defense is to combine them with bioactive molecules including plant-derived compounds. Here, we show that plant treatment with Trichoderma afroharzianum (strain T22) and Systemin, a tomato peptide active in triggering plant defense, confers protection against the fungal pathogens Fusarium oxysporum, Botrytis cinerea and the insect pest Tuta absoluta. The observed defensive response was associated with an increase of Jasmonic acid and related metabolites and a decrease of Salicylic acid.","PeriodicalId":16830,"journal":{"name":"Journal of Plant Interactions","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41675709","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}
