Abstract
The future of pesticide usage in agriculture is uncertain due to its unsustainability, adverse environmental impacts, and its association in enhanced phytopathogen resistance. Hence, this situation urges the development of new sustainable practices in agriculture. A promising approach involves endophytes, which are non-pathogenic microorganisms inhabiting the interior parts of plants. However, due to the vast diversity and complexity of plant microbiomes, a major gap has formed with regards to endophytic research and its application in phytopathogen biocontrol. The gap has mainly been increasing due to the difficulty of isolating underrepresented endophytes and due to limitation of previous genetic tools availability to further research and understand plant-microbe interaction, endophytic biocontrol capabilities and their biocontrol compounds. This review highlights the current challenges being encountered in this research field. Additionally, the research advances through utilization of specialized techniques (CRISPR/Cas9 system, nanoparticles and multi-omics) are highlighted to assist in elucidating the mechanism revolving around plant-microbe interactions and to generate model systems demonstrating improved biocontrol capabilities of endophytes. The ultimate goal of this review is to provide improved approaches that could be implement in an array of microorganism that will enhance the phytopathogen biocontrol field in order to create a sustainable agricultural sector.
