“…Research had demonstrated that bacillus , for instance, could trigger the expression of genes associated with the JA pathway and enhance the production of secondary metabolites in plants to bolster their defense against pest attacks (Zebelo et al, 2016 ). Apart from Bacillus, other commonly utilized PGPR were included Xylaria, Streptomyces, Pseudomonas (Mark et al, 2006 ; Sun et al, 2022 ; Shi et al, 2023 ). Aspergillus spp., a prevalent group of fungi globally, had also been investigated for its potential in disease control.…”

Research on potato diseases had been widely reported, but a systematic review of potato diseases was lacking. Here, bibliometrics was used to systematically analyze the progress of potato disease. The publications related to “potato” and “disease” were searched in the Web of Science (WOS) from 2014 to 2023. The results showed that a total of 2095 publications on potato diseases were retrieved, with the annual publication output increasing year by year at a growth rate of 8.52%. The main countries where publications were issued were the United States, China, and India. There was relatively close cooperation observed between China, the United States, and the United Kingdom in terms of international collaboration, while international cooperation by India was less extensive. Based on citation analysis and trending topics, potential future research directions include nanoparticles, which provides highly effective carriers for biologically active substances due to their small dimensions, extensive surface area, and numerous binding sites; machine learning, which facilitates rapid identification of relevant targets in extensive datasets, thereby accelerating the process of disease diagnosis and fungicide innovation; and synthetic communities composed of various functional microorganisms, which demonstrate more stable effects in disease prevention and control.

“…It appears in all the provinces where cucurbits are planted and cause great damage and crop loss. The pathogen attacks cotyledons and adult plants especially when the environmental conditions are favorable for disease occurrence resulting in significant economic losses, Zhanbin et al (2022). The fungus is easily carried by wind currents, rain splash, farm implements, or the hands and clothes of farm workers.…”

The efficacy of three water plant extracts ie; Mint (Mentha villosa), Basil (Ocimum basilicum )and Aloe vera (Aloe barbadensis) with three concentrations (2 , 4 and 6 ml/ L) and plant essential oils of three plants Castor (Ricinus communis), Thyme ( Thymus vulgaris) and Mint (Mentha villosa) with three concentrations (2.5 , 3.5 and 4.5 ml/L) were studied under greenhouse conditions during two successive seasons (2019-2020 and 2020-2021) on cucumber downy mildew disease management. The obtained results indicated that, application of plant extracts and essential oils significantly reduced the disease severity and increase the yield production (number of fruits / plant and average fruit yield production / plant). For the water plant extracts the Alo vera (6 ml/L concentration) was the best treatment, while the Basil (2 ml/L concentration) showed the lowest effect. For the essential oils, Castor oil (4.5 ml/L) gave the highest effect on decrease the disease severity and increase the yield while the Mint oil (3.5 ml/L) showed the minimum effect.

“…At present, the main strategy to control downy mildew disease relies on synthetic pesticides, but these pesticides contain harmful chemicals that affect the environment and fruit quality and are also detrimental to human health [ 38 ]. Thus, it highlights the necessity of finding an effective and safe method to control crop diseases.…”

Melon (Cucumis melo L.) is a valuable horticultural crop of the Cucurbitaceae family. Downy mildew (DM), caused by Pseudoperonospora cubensis, is a significant inhibitor of the production and quality of melon. Brassinolide (BR) is a new type of phytohormone widely used in cultivation for its broad spectrum of resistance- and defense-mechanism-improving activity. In this study, we applied various exogenous treatments (0.5, 1.0, and 2.0 mg·L−1) of BR at four distinct time periods (6 h, 12 h, 24 h, and 48 h) and explored the impact of BR on physiological indices and the genetic regulation of melon seedling leaves infected by downy-mildew-induced stress. It was mainly observed that a 2.0 mg·L−1 BR concentration effectively promoted the enhanced photosynthetic activity of seedling leaves, and quantitative real-time polymerase chain reaction (qRT-PCR) analysis similarly exhibited an upregulated expression of the predicted regulatory genes of photosystem II (PSII) CmHCF136 (MELO3C023596.2) and CmPsbY (MELO3C010708.2), thus indicating the stability of the PSII reaction center. Furthermore, 2.0 mg·L−1 BR resulted in more photosynthetic pigments (nearly three times more than the chlorophyll contents (264.52%)) as compared to the control and other treatment groups and similarly upregulated the expression trend of the predicted key enzyme genes CmLHCP (MELO3C004214.2) and CmCHLP (MELO3C017176.2) involved in chlorophyll biosynthesis. Meanwhile, the maximum contents of soluble sugars and starch (186.95% and 164.28%) were also maintained, which were similarly triggered by the upregulated expression of the predicted genes CmGlgC (MELO3C006552.2), CmSPS (MELO3C020357.2), and CmPEPC (MELO3C018724.2), thereby maintaining osmotic adjustment and efficiency in eliminating reactive oxygen species. Overall, the exogenous 2.0 mg·L−1 BR exhibited maintained antioxidant activities, plastid membranal stability, and malondialdehyde (MDA) content. The chlorophyll fluorescence parameter values of F0 (42.23%) and Fv/Fm (36.67%) were also noticed to be higher; however, nearly three times higher levels of NPQ (375.86%) and Y (NPQ) (287.10%) were observed at 48 h of treatment as compared to all other group treatments. Increased Rubisco activity was also observed (62.89%), which suggested a significant role for elevated carbon fixation and assimilation and the upregulated expression of regulatory genes linked with Rubisco activity and the PSII reaction process. In short, we deduced that the 2.0 mg·L−1 BR application has an enhancing effect on the genetic modulation of physiological indices of melon plants against downy mildew disease stress.
