“…These extracts may be oligosaccharides, proteins, and sphingolipids that positively impact plant growth characteristics. From PGPF, the proteins extracted enhanced the seed quality features prevalently in pearl millet and musk melon plants, unlike the growth of the control plants [ 63 ]. Likewise, compounds released by PGPF carry out an important function in plant growth and development.…”

The fungi species dwelling in the rhizosphere of crop plants, revealing functions that endeavor sustainability of the plants, are commonly referred to as ‘plant-growth-promoting fungi’ (PGPF). They are biotic inducers that provide benefits and carry out important functions in agricultural sustainability. The problem encountered in the agricultural system nowadays is how to meet population demand based on crop yield and protection without putting the environment and human and animal health at risk based on crop production. PGPF including Trichoderma spp., Gliocladium virens, Penicillium digitatum, Aspergillus flavus, Actinomucor elegans, Podospora bulbillosa, Arbuscular mycorrhizal fungi, etc., have proven their ecofriendly nature to ameliorate the production of crops by improving the growth of the shoots and roots of crop plants, the germination of seeds, the production of chlorophyll for photosynthesis, and the abundant production of crops. PGPF’s potential mode of action is as follows: the mineralization of the major and minor elements required to support plants’ growth and productivity. In addition, PGPF produce phytohormones, induced resistance, and defense-related enzymes to inhibit or eradicate the invasion of pathogenic microbes, in other words, to help the plants while encountering stress. This review portrays the potential of PGPF as an effective bioagent to facilitate and promote crop production, plant growth, resistance to disease invasion, and various abiotic stresses.

“…Endophytes are microbial species, either fungal or bacterial species that have a symbiotic relationship with plant species [17,18]. Because they have a symbiotic relationship, some of the functions endophytes perform include the promotion of plant growth and development by solubilization of potassium and phosphate, production of growth hormones like cytokinin and auxin, improving the host plant overall health and growth by enhancing plant tolerance to different abiotic and biotic stresses, and protecting the plant from pathogenic species [19][20][21]. Moreover, endophytes can synthesize bioactive compounds that can be utilized as raw materials in various industries such as food, medicine, fragrance, and cosmetic industries [22][23][24][25].…”

Background Endophytes are a rich source of novel, distinct, and applicable compounds of interest in agricultural, medical, cosmetic, and pharmaceutical industries. In this respect, they have been attracting growing interest in the past few years. Endophytes are defined as microorganisms such as bacteria and fungi which have a mutualistic relationship with their host plants without causing any harm to their host. In this study, we isolated and identified bacterial endophytes from Centella asiatica collected in Western Cape, South Africa. Results Twenty bacterial endophytes were isolated from Centella asiatica and characterized by using morphological and molecular techniques. Based on molecular traits, the isolates were identified as Pseudomonas sp. strain SGM1, Pseudomonas sp. strain SGM2, Pseudomonas sp. strain SGM3, Pseudomonas sp. strain SGM4, Pseudomonas sp. strain SGM5, Pseudomonas sp. strain SGM6, Pseudomonas sp. strain SGM7, Novosphingobium sp. strain SGM8, Pseudomonas sp. strain SGM9, Pseudomonas sp. strain SGM10, Chryseobacterium sp. strain SGM11, Enterobacter sp. strain SGM12, Enterobacter sp. strain SGM13, Pseudomonas sp. strain SGM14, Enterobacter sp. strain SGM15, Enterobacter sp. strain SGM16, Agrobacterium sp. strain SGM17, Pantoea sp. strain SGM18, Paraburkholderia sp. strain SGM19, and Pseudomonas sp. strain SGM20. Pseudomonas genus was dominant with eleven isolates. Morphological trait results showed that all isolates were gram-negative rod-shaped bacteria. Conclusion According to our understanding, this study revealed the first twenty endophytic bacteria isolated from Centella asiatica growing in the Western Cape Province, South Africa. Data obtained in the current study will increase the knowledge of the already existing microbial diversity associated with Centella asiatica. Further work is needed to evaluate the antioxidant and antibacterial activities in vitro and assess the growth and medicinal compounds of the identified endophytic bacteria in a laboratory scale bioreactors.
