“…Nitrate reductase (NR), Nitrite reductase (NiR) activity Similarly inoculation of AMF increased NR, NiR and GS activities in Dendrobium chrysanthum (Hajong, et al, 2013), NR activity in mycorrhizal plants of Wedilla chinensis (Osbeck) Merril (Nisha and Kumar, 2010). Enhanced NiR activity was reported in ectomycorrhizal inoculated plants of Tilia platyphyllos Scop (Guescini et al, 2007).…”

“…The positive effect of mycorrhizal association on the activity of acid and alkaline phosphatases was also observed in Dendrobium chrysanthum (Stancheva et al, 2008). The application of AMF to seedlings of Catharanthus roseus (L) resulted in higher activities of acid and alkaline phosphatase as compared to uninoculated controls (Hajong et al, 2013).…”

“…Therefore, systematically comparing the microbiota characteristics is critical for screening probiotics, which may be colonized in either the stem or root. Although the endophytic microbiota of D. huoshanense has been extensively studied [9,10], the correlation between D. huoshanense roots and stems in 3 different growth years has seldom been mentioned.…”

The endophytic microbiome in medicinal plants is rich and diverse, but few studies have followed the endophytic microbiome of medicinal plants in different tissues with their growth. In this study, we examined the endophytic bacterial and fungal community structures associated with both the stem and root compartments of Dendrobium huoshanense at different growth years via high-throughput sequencing of 16S rRNA genes and nrDNA fragments of internal transcribed spacer regions. Results indicated that more diverse prokaryotic and fungal operational taxonomic units were detected in roots than in stems, and the alpha diversity of endophytic prokaryotic significantly differed among the 1-, 2-, and 3-year-old roots. The dominant bacterial phyla Proteobacteria Firmicutes, Actinobacteria, Bacteroidetes, and Acidobacteria, and fungal phyla Ascomycota, Basidiomycota, and Ascomycota were detected in the stems and roots with 3 growth years. Moreover, linear discriminant effect size analysis revealed 138 differentially abundant taxonomic clades in the bacterial level, and 197 in the fungal level in six groups. Our results provide evidence for endophytic microbiota communities depending on the tissues and growth years of D. huoshanense. The results from this study should be useful to better understand medicinal plant-microbe interactions.

“…For example, the formation of NO 2catalyzed by nitrate reductase was mainly NADPH-dependent in the roots of plants colonized by AMF, but not in the control (Kaldorf et al, 1998). Nitrate reductase activity in the roots (Subramanian & Charest, 1998;Hawkins & George, 1999;Rani et al, 2017) and shoots (Faure et al, 1998;Hajong et al, 2013;Rani et al, 2017) of the plants colonized by AMF is generally greater than that in the uncolonized control. In plants not colonized by AMF, NO 3reduction occurs predominantly in leaves, and, in the colonized ones, in roots (Kaldorf et al, 1998;Vázquez et al, 2001).…”

The symbiotic interaction between arbuscular mycorrhizal fungi (AMF) and 70-90% of the plant species is largely studied, but ectomycorrhizal fungi, Piriformospora indica, Trichoderma sp., and dark septate endophytes (DSE), also establish beneficial interactions with plants. Despite this, the joint discussion on the biochemical, physiological, and molecular aspects of nutrient transfer, mainly from the extraradical mycelium (ERM) to the plant, is still limited. The objective of this review is to present biochemical, physiological, and molecular approaches to the plant-AMF interaction, as well as to analyze the response of plants to inoculations with different growth-promoting fungi. Here, are highlighted the characteristics of the H+-ATPases and of the transporters of NH4+ and H2PO4- involved in the absorption of phosphorus and nitrogen by the soil through the ERM of the AMF, besides the biochemical aspects of the metabolism of both nutrients in the ERM and their translocations from the ERM to the intraradical mycelium and to the host plant. Finally, the nitrogen fertilizer recovery efficiency in plants inoculated with AMF, Trichoderma sp., P.indica, and DSE fungi is presented. By examining, together, the biochemical, physiological, and molecular aspects of the plant-AMF interaction and the nitrogen fertilizer recovery efficiency in inoculated plants, it is possible to conclude that a low-input agriculture could be achieved with the use of these fungi in agrosystems.
