Biotechnological overview of agriculturally important endophytic fungi
Bartholomew Saanu Adeleke,Olubukola Oluranti Babalola 한국원예학회 2021 Horticulture, Environment, and Biotechnology Vol.62 No.4
The many fascinating aspects of biotechnology in endophytic studies not only concern their interactions with plants but their potential as key players driving the synthesis of certain biomolecules that enhance plant growth, immunity, and protection against environmental stresses. A high microbial population inhabits the rhizosphere due to rhizodeposition and root exudate secretions. The rhizoplane forms a barrier that selectively screens the types of microorganisms infiltrating the root tissues with well-developed hyphae for successful colonization and establishment of endophytic communities within the plant tissues. Fungal endophytes contribute to the physiological and metabolic functions in the host plants, such as nutrient acquisition, nitrogen fixation, and control of plant pathogens. They also contribute to plant growth via complex mechanisms: mutualism or antagonism. The molecular methods of studying these endophytes have provided salient information for harnessing their potential for possible applications in improving agricultural productivity. Despite this, only a small fraction of endophytes have been isolated and explored. Hence, the metagenomic approach has revealed more insights into the endophytic structural diversity and functions for the detection of novel traits that can easily be genetically manipulated for various agricultural and industrial applications. Furthermore, biotechnological applications of biofertilizer from endophytic fungi help ensure a safe environment and aid in the development of agriculturally friendly processes for improved crop yields and productivity.
