“…Siderophores are small molecules that present iron-chelatin properties and are produced by some microorganisms, including endophytic fungi, to bind ferric ions in the rhizosphere (Chowdappa et al 2020;Sr et al 2020). Suebrasri et al (2020) detected the production of siderophores by endophytic strains of Trichoderma koningii ST-KKU 1 , Macrophomina phaseolina SS 1 L 10 and M. phaseolina SS 1 R 10 . In this study, the authors suggested that siderophore production by fungi was important in the growth promotion of sunchoke plants.…”

Endophytic fungi: a tool for plant growth promotion and sustainable agriculture

Endophytic fungi are found in most, if not all, plant species on the planet. They colonise inner plant tissues without causing symptoms of disease, thus providing benefits to the host plant while also benefiting from this interaction. The global concern for the development of more sustainable agriculture has increased in recent years, and research has been performed to decipher ecology and explore the potential of endophytic interactions in plant growth. To date, many studies point to the positive aspects of endophytic colonisation, and in this review, such research is summarised based on the direct (acquisition of nutrients and phytohormone production) and indirect (induced resistance, production of antibiotics and secondary metabolites, production of siderophores and protection for abiotic and biotic stresses) benefits of endophytic colonisation. An in-depth discussion of the mechanisms is also presented.

“…Tryptophan increases enzymatic activity in fungi so that IAA could be produced (Tudzynski & Sharon 2002). The more concentrations of tryptophan produced are directly proportional to the increasing concentration of IAA produced (Suebrasri et al 2020). However, the results obtained also showed that the isolate of Syncephalastrum sp.…”

“…Auxin is a hormone composed of indole rings and can trigger the growth and development of plants (Setyowati et al 2017). The IAA hormone can support root extension and increase the absorption of nutrients from the soil (Suebrasri et al 2020). The presence of endogenous IAA hormones (produced by plants) and the addition of exogenous IAAs can affect plant growth rates.…”

“…This synergism can be utilized both to support the growth of host plants and between species of fungus that interact with each other (Hestrin et al 2019). Research by (Suebrasri et al 2020) shows that endophytic fungi Diaporthe phaseolorum and Macrophomina phaseolina isolated from siam weed and ginger can produce the IAA hormone and increase the growth of sunchoke plant.…”

Some types of fungi are known to have the ability to produce Indole Acetic Acid (IAA). Fungi can be isolated from the rhizosphere and tissues of various plants, including from the rhizosphere and the root "Galam" (Melaleuca cajuputi Powell.), which grow predominantly in peatlands. Therefore, the purposes of this study were: (a) to isolate and measure the potential of fungi from endophytic and rhizospheric of “Galam”(M. cajuputi) as a producer of IAA hormone, (b) determine the types of fungal interaction that occur and their potential to increase the total IAA hormone produced. This research begins with isolation, purification, isolate screening, analysis of IAA hormone production, data analysis, seed germination test and isolates identification. The result showed that the concentration of IAA produced by Penicillium sp. IRZ15 was 5.86 ± 0.47 μg.mL-1 to 8.46 ± 0.26 μg.mL-1 and Syncephalastrum sp. AG15 is 4.77 ± 0.44 μg.mL-1 to 8.77 ± 0.25 μg.mL-1. Meanwhile, the combination of rhizospheric fungi Penicillium sp. IRZ15 and endophytic fungi Syncephalastrum sp. AG15 does not produce significantly different IAA concentrations (6.42 ± 0.34 μg.mL-1 to 9.19 ± 0.50 μg.mL-1 ) compared to fungi used alone without combinations.

“…The plant hormone indole-3-acetic acid (IAA) plays a role in the communication between host plant and microbes, including plant-associated microorganisms [ 1 , 2 , 3 ] and endophytes [ 3 , 4 ], but also plant pathogens [ 5 , 6 , 7 ]. IAA together with other phytohormones is responsible for plant growth and development.…”

The plant hormone indole-3-acetic acid (IAA) is one of the main signals playing a role in the communication between host and endophytes. Endophytes can synthesize IAA de novo to influence the IAA homeostasis in plants. Although much is known about IAA biosynthesis in microorganisms, there is still less known about the pathway by which IAA is synthesized in fungal endophytes. The aim of this study is to examine a possible IAA biosynthesis pathway in Cyanodermella asteris. In vitro cultures of C. asteris were incubated with the IAA precursors tryptophan (Trp) and indole, as well as possible intermediates, and they were additionally treated with IAA biosynthesis inhibitors (2-mercaptobenzimidazole and yucasin DF) to elucidate possible IAA biosynthesis pathways. It was shown that (a) C. asteris synthesized IAA without adding precursors; (b) indole-3-acetonitrile (IAN), indole-3-acetamide (IAM), and indole-3-acetaldehyde (IAD) increased IAA biosynthesis; and (c) C. asteris synthesized IAA also by a Trp-independent pathway. Together with the genome information of C. asteris, the possible IAA biosynthesis pathways found can improve the understanding of IAA biosynthesis in fungal endophytes. The uptake of fungal IAA into Arabidopsis thaliana is necessary for the induction of lateral roots and other fungus-related growth phenotypes, since the application of the influx inhibitor 2-naphthoxyacetic acid (NOA) but not the efflux inhibitor N-1-naphtylphthalamic acid (NPA) were altering these parameters. In addition, the root phenotype of the mutation in an influx carrier, aux1, was partially rescued by C. asteris.
