“…These results were concomitant with several studies that confirmed that many plants extracts have defense enzymes stimulation properties. Goel and Paul [ 58 ] found that the PPO in tomato was stimulated by Azadirachta indica aqueous fruit extracts. Additionally, PAL, POD and PPO in cotton were activated by zimmu ( Allium cepa L. and Allium sativum L.) [ 59 ], and PAL in barely prompted by aqueous extract of leaves of Azadirachta indica [ 60 ].…”

Available information associated with Calotropis procera posted its phytotoxic effect as bio-herbicide scarce works studied its stimulatory/nutritive effect. A pot experiment was performed to assess the validity of using Calotropis procera (C. procera) leaves extract as a bio-stimulant for the growth and quality of a medicinal plant Catharanthus roseus (C. roseus) evaluated by some physio-biochemical indices. Different types of C. procera leaves extracts (CLEs) (methanolic, cold water and autoclaved water extracts) were delivered by two different modes of application. The results revealed that application of CLEs as irrigation or foliar spraying caused a stimulation effect on C. roseus plant. Root and shoot length, dry and fresh weight were significantly improved due to CLEs applications. C. roseus bioactive molecules such as anthocyanins, phenolics, flavonoids, alkaloids, ascorbic acid, reduced glutathione and α-tocopherol were abundance increased significantly with CLEs applications. Reactive oxygen species (ROS) decreased explaining the involvement of CLEs in induction of antioxidant enzymes catalase, ascorbate peroxidase, polyphenol oxidase, guaiacol peroxidase and glutathione-S-transferase for modifying cell oxidative status witnessed by lower lipid peroxidation that kept below the untreated plants’ baseline reflected the improvement of growth and quality rather than phytotoxic effect. The promotion of wholesome-promoting secondary metabolites by CLEs was closely correlated to elevated phenylalanineammonialyase activity. The comparable efficient effect induced by all treatments might be judged by the relation between C. procera phytochemicals and C. roseus metabolism (donor-receiver relation). It is concluded that application of CLEs can be a promising approach for improving the yield and quality of plants despite using polluting fertilizers. The current investigation may provide a matrix for coming studies to seek illustration of numerous plants’ response to C. procera extracts.

Background The sustainable development of rice production is facing severe threats by a variety of pathogens, such as necrotrophic Rhizoctonia solani and hemibiotrophic Xanthomonas oryzae pv. oryzae (Xoo). Mining and applying resistance genes to increase the durable resistance of rice is an effective method that can be used to control these diseases. Results In this research, we isolated and characterized CYP716A16, which is a positive regulator of rice to R. solani AG1-IA and Xoo, and belongs to the cytochrome P450 (CYP450) protein 716A subfamily. Overexpression (OE) of CYP716A16 resulted in enhanced resistance to R. solani AG1-IA and Xoo, while RNA interference (RNAi) of CYP716A16 resulted in increased susceptibility compared with wild-type (WT) plants. Additionally, jasmonic acid (JA)-dependent defense responses and reactive oxygen species (ROS) were activated in the CYP716A16-OE lines after R. solani AG1-IA inoculation. The comparative transcriptomic and metabolomics analysis of CYP716A16-OE and the WT lines showed that OE of CYP716A16 activated the biosynthesis of flavonoids and increased the amounts of narcissoside, methylophiopogonanone A, oroxin A, and amentoflavone in plants. Conclusion Based on these results, we suggest that JA-dependent response, ROS level, multiple resistance-related proteins, and flavonoid contents play an important role in CYP716A16-regulated R. solani AG1-IA and Xoo resistance. Our results broaden our knowledge regarding the function of a P450 protein 716A subfamily in disease resistance and provide new insight into the molecular mechanism of rice immune response.

“…The antifungal activity of medicinal plant extracts against the fungal pathogens may be due to indirect effects on host plants such as induction of host plant immune systems against pathogens (Abkhoo and Jahani, 2017). Also, other responses of medicinal plant include; induced defense-related genes, pathogenesis-related (PR) proteins, accumulation of phytoalexins, and deposition of lignin and programmed cell death (Goel and Paul, 2015). POX considered ones for important group of enzymes involved in plant resistance mechanisms, such as synthesis of phenolic compounds and the formation of structural barriers (Dalisay & Kuć, 1995).…”

Bakanae rice disease caused by fungus Fusarium fujikuroi Nirenberg (F. fujikuroi) and occurs in the most growing rice areas of the world. Transmission of this disease by soil and seed, so seed addressing by different material is useful to control bakanae disease. This study is focused on antifungal activity for some plant extracts i.e. Ammi visnaga (A. visnaga), Eucalyptus globulus (E. globulus), Artemisia judaica (A. judai) and Coriandrum sativum (C. sativum) on the linear growth of F. fujikuroi. Identification of chemical compounds was done for two plant extracts A. visnaga and E. globulus by qualitative and quantitative phytochemical screening, and gas chromatographymass spectrometry (GC-MS) analysis. Seeds was treatments with plant extracts with different concentrations under greenhouse condition. Changes in seedling content for enzymes such as peroxidase (POX), polyphenol oxidase (PPO) and hydrogen peroxide (H 2 O 2) after 7 and 14 days of treatments by plant extracts has been observed. Management bakanae disease under field condition by seed treatment with plant extracts. The results indicate that A. visnaga was the most effective on the linear growth with concentration 500 ppm. The obtained results from qualitative phytochemical tests for A. visnaga indicates presence of coumarins, tannins, saponin, terpenoids, flavonoids and steroids and absence of phenols. E. globulus found tannins, phenols, saponin, terpenoids, flavonoid and absences of coumarins and steroids. Tannins and terpenoids were the highest quantitative phytochemical constituent determined in A. visnaga. While phenols and flavonoids were the most active phytochemical constituents determined in E. globulus. The chemical constituents for GC-MS analysis of A. visnaga were benzene methyl, khellin, visnagin and vitamin E. While, E. globulus has eucalyptol, terpinen, ellagic acid and gallic acid. Under greenhouse condition, A. visnaga was the most effective in reducing the number of death and number of infected seedling, increasing the germination % at different concentrations compared with other treatments. POX, PPO and H 2 O 2 were induced in inoculated seedling compared with the un-inoculated seedling. Seed treatments with A. visnaga and E. globulus produced the highest enzymes increase and decreased H 2 O 2 content in seedling. Under field condition, there are no significant difference between A. visnaga and Rhizolex-T 50% as seed treatment in reduction of disease incidence or disease severity of bakanae in 2017 and 2018 growing seasons. Grain yield was increased in treated plant with A. visnaga and Rhizolex-T 50% in both seasons.
