“…The decline in protein level may be due to the disruption in translation pathway after being exposed to the allelochemicals released. This phenomenon was also observed in plants exposed to both biotic and abiotic stress (Parida et al, 2004;Jali et al, 2019).…”

Allelopathic impacts of Mikania micrantha Kunth were investigated on the rate of seed germination, growth, biomass, photosynthetic pigments, total soluble protein, phenolics and proline content of Macrotylama uniflorum (Lam.) Verdc. The extracts inhibited germination, growth, biomass, chlorophyll, carotenoid and protein contents. The protein content of M. uniflorum decreased to 8.48 mg/g at 200 mg/ml. Similarly shoot length, root length also decreased up to 5.11 cm, 0.85 cm respectively and water content increased with increasing concentration of weed extracts. The leaf extracts resulted in an increase in the phenolics (19.66 mg) and proline (24.49 mg) content of the crop plant. The aqueous extracts of leaves caused detrimental impact on growth and physiology of the crop plant and this might be due to release of secondary metabolites. This present investigation may further lead to identification of certain secondary metabolites or allelo-chemicals for agricultural application and might enhance the level of crop protection against several other harmful plant species.

“…A polysaccharide extracted from R. apiculata and R. mucronata and some other mangroves exhibited positive activity against human immunodeficiency virus (HIV) [68] . It was reported that cadmium induced a low molecular weight (~23 kDa) pathogen related protein in rice against blast causing Pyricularia oryzae which indicates the role of small molecular weight protein could induce antimicrobial activity [69] . R. apiculata possesses 2,6‐dimethoxy‐ p‐ benzoquinone, which was identified as one of the active constituents against bacterial and fungal pathogens [25] .…”

Mangroves are abundant in bioactive natural substances that fight off pathogenic diseases. Different parts of R. apiculata, an abundant mangrove found in Bhitarkanika National Park, India were extracted with methanol and a mixture of solvents methanol/ethanol/chloroform (60 : 20 : 20) to evaluate their antimicrobial properties. The combination solvent extract of bark had the highest zone of inhibition (ZOI) of 18.62 mm against Pseudomonas aeruginosa and a ZOI of 17.41 mm against Streptococcus mitis. Bark extracts had the highest DPPH (43 %) and FRAP (96 %) activities. The combination solvent bark extract of R. apiculata had the highest ZOI of 20.42 mm (lowest MIC of 2.12 μg/ml) against Candida albicans and ZOI of 15.33 mm (MIC of 3.02 μg/mL) against Penicillium chrysogenum. Combination bark extracts of R. apiculata contained flavanols than methanolic extracts. The crude extract of R. apiculata bark made with a mixture of solvents containing more active ingredients could be used in novel drug formulation.

“…Since environmental pollution and food safety as well as pesticide resistance caused by the application of traditional chemical pesticides to control the plant diseases, the demand of environmentally friendly ways to control plant diseases has become an important research topic ( Datnoff et al, 2007 ). Among of them, mineral nutrition such as silicon (Si) has long been recognized as an important component of disease control practices, which impacts plant disease tolerance or resistance ( Datnoff et al, 2007 ; Fones et al, 2010 ; Yao et al, 2012 ; Fones and Preston, 2013 ; Hörger et al, 2013 ; Kaur et al, 2016 ; Morkunas et al, 2018 ; Cabot et al, 2019 ; Jali et al, 2019 ; Liu et al, 2022 ). Solid research evidences demonstrate that the amounts of trace element nutrient Se in plants improve the plant growth and increase the tolerance against biotic and abiotic stress ( Razak et al, 1991 ; Poschenrieder et al, 2006 ; Boyd, 2007 ; Freeman et al, 2007 ; Trumble and Sorensen, 2008 ; Pilon-Smits et al, 2009 ; Zhao and McGrath, 2009 ; Zhu et al, 2009 ; Winkel et al, 2011 ; Wu et al, 2015 ; Hossain et al, 2021 ) and appropriate Se can significantly enhance the antioxidant enzyme activities in plants and reduce the activities of reactive oxygen species (ROS) and also the levels of lipid peroxidation, which could enhance the antioxidant enzyme activities in plants ( Feng et al, 2013 ; Lanza et al, 2021 ).…”

Synergistic Effect of Melatonin and Selenium Improves Resistance to Postharvest Gray Mold Disease of Tomato Fruit

Melatonin (MT) is a ubiquitous hormone molecule that is commonly distributed in nature. MT not only plays an important role in animals and humans but also has extensive functions in plants. Selenium (Se) is an essential micronutrient for animals and humans, and is a beneficial element in higher plants at low concentrations. Postharvest diseases caused by fungal pathogens lead to huge economic losses worldwide. In this study, tomato fruits were treated with an optimal sodium selenite (20 mg/L) and melatonin (10 μmol/L) 2 h and were stored for 7 days at room temperature simulating shelf life, and the synergistic effects of Se and MT collectively called Se-Mel on gray mold decay in tomato fruits by Botrytis cinerea was investigated. MT did not have antifungal activity against B. cinerea in vitro, while Se significantly inhibited gray mold development caused by B. cinerea in tomatoes. However, the interaction of MT and Se showed significant inhibition of the spread and growth of the disease, showing the highest control effect of 74.05%. The combination of MT with Se treatment enhanced the disease resistance of fruits by improving the activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), as well as increasing the gene expression level of pathogenesis-related (PR) proteins. Altogether, our results indicate that the combination of MT and Se would induce the activation of antioxidant enzymes and increase the expression of PR proteins genes that might directly enhance the resistance in tomato fruit against postharvest pathogenic fungus B. cinerea.
