Special Issue Information

Dear Colleagues,

The exponentially increasing human population has led to an enormous demand for food, especially in developing countries. However, current agricultural practices rely heavily on the intensive use of agrochemicals, leading to environmental degradation. Therefore, instead of intensifying agriculture or increasing the cultivated land, there is an urgent need to explore alternative options for enhancing food production that is in tune with the principles of sustainability. Agriculturally important microorganisms can play a crucial role in this field. In nature, plants are intricately associated with microbes, both symbiotically and antagonistically for furthering their growth and development. Plant growth-promoting microorganisms often referred to as the microbiota, are capable of increasing the plant’s capacity to absorb nutrients, improving water use efficiency, and boosting immune responses. Thus, utilizing the plant microbiome can be a successful approach for meeting the global food demand and at the same time fulfilling the objective of sustainable development. 

Being aware of the importance of sustainability, we are pleased to announce the launch of a Special Issue titled “Plant-Microbe Interactions for Sustainable Agriculture in Changing Environment”, with the aim to focus on the role of microbiota in sustainable agriculture. The scope of this Special Issue covers a wide range of topics on the beneficial role of microbes, ranging from stress management to applications in specific crops. Authors are welcome to submit both research and review articles for this Special Issue. The topics of interest include (but are not limited to) the following:

  • Fundamentals of plant-microbe interactions;
  • Rhizosphere, rhizobacteria and their interactions;
  • Plant-microbe interactions during biotic and abiotic stresses;
  • Plant-microbe interactions and crop productivity;
  • Role of microbes in sustainable agriculture;
  • Omics in plant-microbe interactions

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

The adverse effects of modern fungicide consumption have caused many issues in the agroecosystem. Hence, under sustainable agriculture concepts, it is important to research alternatives to the currently used fungicide. The use of secondary metabolite-containing herbal extracts for treating plant diseases has become the latest trend in sustainable and green agriculture. However, the poor solubility and volatile nature of many compounds cause practical issues when using them in the field. Hence, bioactive compound delivery through nano- or micro-particles has become a successful technique to improve the solubility and delivery of secondary metabolites to targeted sites. In the current study, the ethyl acetate (EtOAc) extract from dried leaves of Vernonia amygdalina was tested against Phytophthora palmivora isolated from Durian (Durio zibethinus) root rot. Further, the potential of enhancing the effect of V. amygdalina EtOAc treatment through microspheres loaded with V. amygdalina EtOAc extract was also investigated. The microspheres encapsulated with Eudragit® E were synthesized under different electrospray conditions to obtain the microspheres with the highest efficacy. The poison media assays evaluated the fungal growth inhibition efficiency of the V. amygdalina EtOAc crude extract and the synthesized microspheres. The study reveals that the V. amygdalina EtOAc extract has the potential to suppress the growth of P. palmivora. Interestingly, the synthesized microspheres showed immense growth inhibition in P. palmivora, with a 61.10 µg/mL decrease in ED50 compared to the direct usage of V. amygdalina EtOAc extract.
