“…Relatedly, nanoemulsions from the essential oils Melaleuca alternifolia or Cymbopogon martini in aloe polysaccharide suspension were used to treat Xanthomonas fragariae in strawberries. The treatment significantly reduced the biotic stress caused by the pathogen [ 124 ]. Vega-Vásquez et al [ 125 ] synthesized several nanoemulsions by using essential oils, including cinnamon, peppermint, clove bud, oregano, coriander seed, geranium, and red thyme, followed by evaluation and observation of a strong antifungal activity against Botrytis cinerea , which is a broad host range necrotrophic phytopathogen that affects different plant species.…”

Climate change is more likely to have a detrimental effect on the world’s productive assets. Several undesirable conditions and practices, including extreme temperature, drought, and uncontrolled use of agrochemicals, result in stresses that strain agriculture. In addition, nutritional inadequacies in food crops are wreaking havoc on human health, especially in rural regions of less developed countries. This could be because plants are unable to absorb the nutrients in conventional fertilizers, or these fertilizers have an inappropriate or unbalanced nutrient composition. Chemical fertilizers have been used for centuries and have considerably increased crop yields. However, they also disrupt soil quality and structure, eventually impacting the entire ecosystem. To address the situation, it is necessary to develop advanced materials that can release nutrients to targeted points in the plant-soil environment or appropriate receptors on the leaf in the case of foliar applications. Recently, nanotechnology-based interventions have been strongly encouraged to meet the world’s growing food demand and to promote food security in an environmentally friendly manner. Biological approaches for the synthesis of nanoscale agro-materials have become a promising area of research, with a wide range of product types such as nanopesticides, nanoinsecticides, nanoherbicides, nanobactericides/fungicides, bio-conjugated nanocomplexes, and nanoemulsions emerging therefrom. These materials are more sustainable and target-oriented than conventional agrochemicals. In this paper, we reviewed the literature on major abiotic and biotic stresses that are detrimental to plant growth and productivity. We comprehensively discussed the different forms of nanoscale agro-materials and provided an overview of biological approaches in nano-enabled strategies that can efficiently alleviate plant biotic and abiotic stresses while potentially enhancing the nutritional values of plants.

“…It is worth noting that the stomatal length, width, and aperture of susceptible materials are much larger than those of resistant varieties. Stomata are natural openings through which many pathogenic fungi enter plants and the outside world, and their closure is the pivotal line of defense against plant pathogens Luiz et al, 2022). These ndings suggest that the larger size of stomata and bigger stomata aperture are more conducive to pathogen invasion.…”

Chrysanthemum black spot disease caused by Alternaria alternate infestation is a widespread and extremely destructive foliar disease of chrysanthemums. Therefore, it is necessary to breeding germplasm resources of disease-resistant chrysanthemum to deal with this problem, and the identification of the disease-resistant chrysanthemum-related genera is of great significance to improve the targeted traits of chrysanthemums. This study was aimed at evaluating the disease resistance of chrysanthemum-related genera by using two different artificial inoculation methods and through the analysis of the physical and chemical defense mechanisms of plants. Here, according to the disease index, we divided 14 germplasms into three grades: 2 disease-resistant germplasms, 11 moderately sensitive germplasms, and 1 sensitive germplasm. We found that the trichomes density and wax content on the leaf surface of the disease-resistant germplasms were significantly higher than those of the sensitive germplasm, while the stomatal aperture and size of the resistant material were smaller than that of the sensitive germplasm. In addition, we found that the leaf extract of the disease-resistant germplasm effectively inhibited the growth rate of A. alternate mycelium on the plate, and GC-MS components found that the leaves of resistant germplasm contained more volatile antifungal organic compounds, of which falcarinoland Germacrene D might play an important role in resistance to chrysanthemum black spot disease. In summary, the physiochemical defense mechanisms explored in this study provided a reference for resolving disease resistance in chrysanthemums, and the resistant germplasm identified can be used as parents for hybrid breeding or grafting rootstocks for improved resistance in chrysanthemums.

“…After the removal of the organic solvent and centrifugation, NPs are obtained. Commonly used emulsifiers include F68 [104], F80 [105], Tween 20 [106], and triglycerides [107]. During the preparation process, the key factors that influence the quality of the NPs are the ratio of the organic phase to the internal water phase, the ratio of the external water phase to the organic phase, and the concentration of the emulsifier [108].…”

Herb polysaccharides (HPS) have been studied extensively for their healthcare applications. Though the toxicity was not fully clarified, HPS were widely accepted for their biodegradability and biocompatibility. In addition, as carbohydrate polymers with a unique chemical composition, molecular weight, and functional group profile, HPS can be conjugated, cross-linked, and functionally modified. Thus, they are great candidates for the fabrication of drug delivery systems (DDS). HPS-based DDS (HPS-DDS) can bypass phagocytosis by the reticuloendothelial system, prevent the degradation of biomolecules, and increase the bioavailability of small molecules, thus exerting therapeutic effects. In this review, we focus on the application of HPS as components of immunoregulatory DDS. We summarize the principles governing the fabrication of HPS-DDS, including nanoparticles, micelles, liposomes, microemulsions, hydrogels, and microneedles. In addition, we discuss the role of HPS in DDS for immunotherapy. This comprehensive review provides valuable insights that could guide the design of effective HPS-DDS.
