Abstract

With the increasing use of microflora, including intestinal bacteria, in medical and health care, research is also expanding to plant microflora. Plant tissues, similar to those of animals, harbor resident microorganisms. Some microorganisms living symbiotically in plant roots are believed to attract other fungi and bacteria, forming a microbiome that promotes plant growth. A group of microorganisms act as a core of the microbiome, collectively referred to as endophytes. Endophytic microbes, especially fungi and bacteria assist plants by supplementing nutrient acquisition, synthesizing plant growth regulators and provide immunity to plants against phytopathogens, biotic and abiotic stresses. Orchids, belonging to the diverse family Orchidaceae, are renowned for their vibrant and fragrant blossoms and thrive in nearly all terrestrial ecosystems except the poles and extremely dry deserts, with their greatest diversity found in the tropical region. Orchids are economically important for their ornamental value, medicinal properties, and use in food products. Their seeds lack endosperm, and they must depend on endophytes from the very early stage of life: germination, growth, and adaptation. Recent research into orchids has focused on isolation and identification of the endophytes that directly or indirectly contribute to the growth and development of orchids as well as the production of valuable secondary metabolites. This review considers both the role such endophytes play and explains how such symbiotic partners can be used in the plant tissue culture technique to help increase plant growth, productivity, protection against pathogens and stress resistance.
