“…However, scaling up JA production in a fermenter or in a shaking incubator at 190 rpm and 30 °C with a dissolved oxygen saturation in the culture medium of up to 150 L ( Farbood et al, 2001 ) as well as using a fixed inoculation ratio of 0.5 g L −1 of dry biomass of culture medium was shown to further improve JA yield ( Miersch et al, 1987 ). In addition, it was of advantage to use homogenized mycelium and not spores ( Almeida, Altuna & Michelena, 2001 ; Dos Santos et al, 2014 ; Dos Santos, Innocentini & Lourenco, 2014 ). Agitation turned out to be another critical aspect for JA production, because shaking speeds above 200 rpm lead to increased synthesis of extracellular polysaccharides that visibly increased the viscosity of the culture medium ( Selbmann, Crognale & Petruccioli, 2004 ), which had a negative effect on JA production ( Eng, Gutiérrez-Rojas & Favela-Torres, 1998 ; Miersch et al, 1987 ).…”

Jasmonic acid (JA) and its derivatives called jasmonates (JAs) are lipid-derived signalling molecules that are produced by plants and certain fungi. Beside this function, JAs have a great variety of applications in flavours and fragrances production. In addition, they may have a high potential in agriculture. JAs protect plants against infections. Although there is much information on the biosynthesis and function of JA concerning plants, knowledge on these aspects is still scarce for fungi. Taking into account the practical importance of JAs, the objective of this review is to summarize knowledge on the occurrence of JAs from fungal culture media, their biosynthetic pathways and the culture conditions for optimal JA production as an alternative source for the production of these valuable metabolites.

“…Botrytis fungi can produce abscisic acid [33], Aspergillus fungi can synthesize gibberellins [34], and abscisic acid and gibberellins inhibit betalain biosynthesis [35]. B. rhodina has the potential to produce jasmonate under controlled conditions [36]. Jasmonate can be induced by ultraviolet-B irradiation and can promote betalain accumulation [37].…”

The synthesis of betalain using microorganisms is an innovative developmental technology, and the excavation of microorganisms closely related to betalain can provide certain theoretical and technical support to this technology. In this study, the characteristics of soil microbial community structures and their functions in the rhizospheres of white-fleshed dragon fruit (Hylocereus undatus) and red-fleshed dragon fruit (Hylocereus polyrhizus) were analyzed. The results show that the soil bacterial and fungal compositions in the rhizospheres were shaped differently between H. undatus and H. polyrhizus. Bacterial genera such as Kribbella and TM7a were the unique dominant soil bacterial genera in the rhizospheres of H. undatus, whereas Bradyrhizobium was the unique dominant soil bacterial genus in the rhizospheres of H. polyrhizus. Additionally, Myrothecium was the unique dominant soil fungal genus in the rhizospheres of H. polyrhizus, whereas Apiotrichum and Arachniotus were the unique dominant soil fungal genera in the rhizospheres of H. undatus. Moreover, TM7a, Novibacillus, Cupriavidus, Mesorhizobium, Trechispora, Madurella, Cercophora, and Polyschema were significantly enriched in the rhizospheres of H. undatus, whereas Penicillium, Blastobotrys, Phialemonium, Marasmius, and Pseudogymnoascus were significantly enriched in the rhizospheres of H. polyrhizus. Furthermore, the relative abundances of Ascomycota and Penicillium were significantly higher in the rhizospheres of H. polyrhizus than in those of H. undatus.
