“…The present study indicated a positive effect of AMF inoculation on plant growth of trifoliate orange, which also had been proved in various host plants such as Metrosideros laurifolia (Amie et al, 2019), maize (Ghorchiani et al, 2018), tea (Shao et al, 2018) and tomato (Vani et al, 2018). The Xac infection had no effect on plant growth of trifoliate orange and root mycorrhizal colonization, the possible reason of which was short-term time for the Xac infection (5 days), not enough to cause any responses of plant growth and mycorrhizas.…”

Citrus canker is a quarantined disease, severely harming citrus plants. Soil beneficial arbuscular mycorrhizal fungi (AMF) can provide a biological control pathway to resist pathogens. This work was to test changes of signal substances including hydrogen peroxide (H2O2), nitric oxide (NO), calmodulin (CaM), salicylic acid (SA) and jasmonic acid (JA) and the pathogen defense gene expression in roots of AMF (Paraglomus occultum) and non-AMF trifoliate orange (Poncirus trifoliata) seedlings after infected by a expressions citrus canker pathogen (Xanthomonas axonopodis pv. Citri, Xac). AMF inoculation significantly improved plant height, stem diameter and leaf number. Xac infection dramatically decreased root H2O2, NO, and SA levels, but increased root CaM and JA concentrations in non-AMF seedlings. There were higher H2O2 and CaM levels and lower JA levels in Xac-infected seedlings than in non-Xac-infected seedlings under mycorrhization. Under non-Xac infection, mycorrhizal treatment reduced root H2O2, NO, and SA but increased CaM and JA levels. However, under Xac infection, mycorrhizal inoculation distinctly accelerated root H2O2, NO, CaM, and SA accumulation, accompanied with up-regulated expression levels of root PtEPS1 (enhance pseudomonas susceptibility 1) and PtPR4 (pathogenesis related gene 4), indicating that Xac stimulated mycorrhizal roles in enhancing resistance of citrus canker. Such results imply that citrus plants with pre-inoculated AMF had stronger resistance to Xac infection through increasing signal substrate accumulation and pathogen defense gene expressions. ********* In press - Online First.

“…Most plants live in close collaboration with a variety of soil organisms. Among them, AMF play a remarkable role in plant growth, development, and productivity, as they can help their host plants better acclimatise to biotic and abiotic conditions (Lenoir et al 2016;Machineski et al 2018;Vani et al 2018).…”

“…On the other hand, the hyphae of AMF are an important channel for soil nutrients and water to enter plants (Karagiannidis et al 2002;H.H. Zhang et al 2018) and can extend several centimeters into the soil (Vani et al 2018). AMF hyphae can therefore contribute to plantlet growth (Wicaksono et al 2018;Toprak, 2020;Chenchouni et al 2020), root morphogenesis (Giri et al 2003;Gamalero et al 2004;Shao et al 2018), uptake of mineral nutrients, such as phosphorus (P), nitrogen (N), and micronutrients (Gamalero et al 2004;Koch et al 2006;Machineski et al 2018;Pel et al 2018), improvement of plant photosynthetic capacity and PSII function (Chen et al 2017;Mathur et al 2018), increased disease resistance (Douds et al 2016;Jacott et al 2017), stabilisation of soil aggregates (Wright & Upadhyaya 1998;Miller & Jastrow 2000;Rillig et al 2002;Zhang et al 2016), and enhancement of environmental stress tolerance (Zhang et al 2014;Bitterlich et al 2018;Turrini et al 2018).…”

Background: Catalpa bungei is a well-known, valuable, ornamental, high-quality timber tree traditionally cultivated in China because of its excellent quality, decay resistance, wide applicability, and attractive form. The aim of this study was to evaluate the effects of inoculation with arbuscular mycorrhizal fungus (AMF) on the transplant survival rate and growth of C. bungei seedlings under greenhouse conditions. Methods: Two treatments were applied in a completely randomized experimental design: inoculation with Rhizophagus intraradices, and, as a control, soil without inoculum. Results: Four months after inoculation, AMF had colonized 76.05% of plant roots and significantly improved plant growth. With the establishment of the symbiotic relationship, AMF inoculation significantly improved the seedling transplant survival rate by 20%, promoted major growth traits (plant height, basal diameter, leaf area, and specific leaf area), accelerated biomass accumulation (roots, stems, and leaves), and changed the biomass allocation patterns. In addition, compared with non-inoculated treatments, inoculation with AMF increased photosynthetic parameters and chlorophyll contents, elevated major root morphological parameters, changed the proportion of particle sizes of soil micro-aggregates, and promoted the accumulation of nutrients in roots and leaves. Conclusions: The effects on transplant survival, growth and development were more pronounced in C. bungei seedlings inoculated with R. intraradices. Mycorrhizal seedlings of C. bungei can therefore be widely applied in plant transplantation and production practices.

Research into the symbiotic relationship between plants and arbuscular mycorrhizal fungi (AMF) is key for sustainable agricultural intensification. The objective of the present study is to evaluate native AMF at the monosporic level in greenhouse-grown, economically important crops. Agricultural soil samples from three locations (Saltillo, Zaragoza, and Parras) were obtained by combining portions resulting from a zigzag sampling pattern. From these samples, 15 morphotypes were extracted according to a modified Gerdemann’s technique and monosporically inoculated on melon, cucumber, tomato, and onion, 30 days after their sowing. Under a completely random experimental design, 16 treatments with three repetitions were defined. Plant height, root length, stem diameter, total fresh weight, fresh root weight, dry root weight, bulb weight, fresh leaf weight, total dry weight, flower number, leaf number, fruit number, spore number, and percentage of colonization were all evaluated. The results were subjected to the analysis of variance (ANOVA) and the Tukey comparison test (p ≤ 0.05), which showed that the monosporic inoculation favors significantly the AMF and the host, while the T6 (Saltillo spore + Steiner modified with 20% of the normal phosphorus concentration) showed a greater response uniformity on onion and melon, which indicates its great potential as an inoculum.
