“…Pecan trees have a dedicated mutualistic symbiosis with T. lyonia in North America orchards [20,21]. Previous studies also demonstrated the mycorrhiza formation on pecan seedlings with T. melanosporum, T. brumale, T. borchii and T. aestivum [3,20,22,38]. In the first 12 months of 'Elliott' mycorrhization, T. melanosporum and T. brumale produced a root colonization level of 37.3 and 34.5%, respectively.…”

“…The colonization level reached by the pecan seedlings here inoculated, ranging from 41 to 64%, is among the highest known mycorrhization levels achieved for the different truffle inoculation procedures. In previous studies, the highest percentage of mycorrhization on pecan was recorded at ≈61% for T. borchii and ≈40% for T. aestivum [22] or 20-50% of root system for T. melanosporum and T. brumale [3,22,[38][39][40][41].…”

Evaluation of Pecan [Carya illinoinensis (Wangenh.) K. Koch] Cultivars for Possible Cultivation for Both Fruit and Truffle Production in the Puglia Region, Southeastern Italy

Yield and different nut parameters were measured for two growing seasons on mature (28–29 years) trees of 11 pecan cultivars grown in an experimental orchard located in the Puglia Region, Southeastern Italy. ‘Shoshoni’ and ‘Shawnee’ pecan seedlings were inoculated with three truffle species (Tuber borchii—known as the ‘whitish truffle’, T. aestivum—called the ‘summer truffle’, and T. melanosporum—the common ‘Black truffle’) and investigated for six months. The level of ectomycorrhizal colonization was assessed 6 and 12 months after inoculation. Results indicated that ‘Wichita’, ‘Shoshoni’, and ‘Pawnee’ performed well in the pedoclimatic conditions of the area with a yield higher than 20 kg/tree and a kernel dry weight of ≅3 g. These preliminary yield results suggested that some pecan cultivars could deserve consideration for cultivation in the Puglia Region, whereas others with low yield and a stronger alternate bearing should not be considered. Plant height, number of leaves, chlorophyll content (expressed as a SPAD unit) and stem diameter partially indicated the increase in ecological fitness in truffles-inoculated plants. Successful mycorrhization indicated ‘Shoshoni’ and ‘Shawnee’ as suitable to establish ectomycorrhizal symbiosis with T. aestivum, T. borchii, and T. melanosporum cultivation under Puglia climatic conditions. The results also showed that the applied protocol was adequate to obtain healthy mycorrhized seedlings appropriate for commercialization and plantation for truffles production on pecan in the future.

“…We speculated that the results were associated with the accumulation of more litter in the bulk soil. Pecan trees can form ectomycorrhizal with a wide range of fungi, including Boletus , Hebeloma , Peziza , Tomentella , and Tuber , which are edible and have nutritional or medicinal value (Freiberg et al, 2021; Grupe 2nd et al, 2021; Habtemariam et al, 2021). We found that Pezizales were enriched in the bulk and rhizosphere soils of the 7‐year‐old pecan plantation, but not in those of the 12‐year‐old pecan plantation (Figure S1c,d).…”

Pecan plantation age influences the structures, ecological networks, and functions of soil microbial communities

Understanding the changes in microbial communities with increasing plantation age will benefit the maintenance of forest health and productivity and the sustainable development of forest ecosystems. It was not clear before this study whether the microbial communities of pecan (Carya illinoinensis) plantations would be affected by their age. Based on MiSeq sequencing, we studied the effects of pecan age on microbial communities in rhizosphere and bulk soils of pecan plantations for the first time.The results showed that the bacterial alpha diversity of bulk soil increased significantly with plantation age (p < 0.05), while fungal alpha diversity was less influenced by pecan age in both rhizosphere soil and bulk soil. Pecan age significantly influenced

“…Tomentella and Tuber were also identified as keystone taxa in the fungal networks (Supplementary Table S6). Previous studies verified that pecan trees can form ectomycorrhizal associations with a wide range of fungi, including Tomentella and Tuber, whose substrates are edible and have nutritional or medicinal value (Freiberg et al, 2021;Grupe et al, 2021;Habtemariam et al, 2021). Despite the dominance of many beneficial species in bacterial and fungal networks had been found, some pathogenic fungi still need to be noticed in the management of pecan plantations, such as the bulk-soil keystone genus of Fusarium and the rhizosphere-soil genus of Cladophialophora in this study, which were usually reported as the plant pathogens and environmental saprobes (Badali et al, 2008;Rampersad, 2020;He et al, 2021).…”

A Stronger Rhizosphere Impact on the Fungal Communities Compared to the Bacterial Communities in Pecan Plantations

Understanding microbial communities associated with bulk and rhizosphere soils will benefit the maintenance of forest health and productivity and the sustainable development of forest ecosystems. Based on MiSeq sequencing, we explored the differences between the bulk soil and the rhizosphere soil on bacterial and fungal communities of pecan plantation. Results suggested that rhizosphere-associated fungal rather than bacterial community structures differed from bulk soil, and rhizosphere soil had lower fungal diversity than bulk soil. Actinobacteria and Cantharellales were the bacterial and fungal biomarkers of the rhizosphere soil of pecan plantation, respectively. In addition, Pleosporales, which are mainly involved in saprophylaxis and plant pathogenic processes, was identified as one of the most important fungal biomarkers for the bulk soil, and the FunGuild predicted a higher relative abundance of pathogenic fungi in bulk soil compared to rhizosphere soil. The pH, ammonium nitrogen (NH4+-N), nitrate nitrogen (NO3--N), and total carbon (TC) contents drove microbial community structure and composition. The bacterial network was simpler in the rhizosphere soil than in the bulk soil. However, fungi showed the opposite network pattern. Keystone species in bacterial and fungal networks were mostly involved in nutrient cycling and the C cycling, and were found to be enriched in the rhizosphere soil. Overall, in terms of bacterial and fungal communities, the rhizosphere soil behaves more healthily than the bulk soil and has a higher potential for nutrient cycling.
