Sympatric species develop more efficient ectomycorrhizae in the Pinus-Laccaria symbiosis. Ibeth Rodríguez-Gutiérrez a. Daniel Ramírez-Martínez a. Virginia Jacob-Cervantes b. María del Pilar Ortega-Larrocea d. Elsa Arellano-Torres e. The mycorrhizal symbiosis is optimal when the plant and the fungi are sympatric.

However, in forest plantations the inoculum typically belongs to exotic or allopatric fungi. In this paper, the efficiency of mycorrhization was determined by evaluating the effect of 2 sympatric fungi species Laccaria trichodermophora and L. After 1 year of growth, we evaluated the mycorrhization percentage, plant height, diameter at root collar, dry weight and nutrient contents N, P, K of aerial part and roots.

The mycorrhization percentage varied from The treatments that showed higher efficiency biomass accumulation and K contents were those inoculated with sympatric species. All Laccaria treatments, either in the presence or absence of the bacteria, showed a better response compared to not inoculated controls. This work demonstrates the significance of using inocula of sympatric species as these are genetically predisposed to associate with their hosts, naturally adapted to the local environmental and edaphic conditions compared with those of allopatric origin.

Sin embargo, en las plantaciones forestales típicamente se usa inóculo de hongos exóticos. El porcentaje de micorrización varió de Todos los tratamientos con Laccaria, en presencia o ausencia de bacterias, mostraron una mejor respuesta en comparación con los controles no inoculados. Palabras clave: Inóculo ectomicorrízico; Exótico; Laccaria laccata; Laccaria trichodermophora; Laccaria vinaceobrunnea; Laccaria bicolor; Pseudomonas fluorescens; Pinus montezumae.

The ectomycorrhizal symbiosis between fungi and trees or shrubs, both Gymnosperms and Angiosperms, mainly occurs in temperate and boreal zones. However, the outcome of the mycorrhizal symbiosis varies from positive to neutral even negative depending on the plant species, the species of fungus and their origin, as well as the soil fertility Barroetaveña et al. The origin of the participants, i. In previous studies with arbuscular mycorrhizal fungi, the results indicate significant effects in the local adaptation when the tests have included sympatric plants and fungi, instead of allopatric combinations Hoeksema et al.

Laccaria species are habitat pioneers and they have been used as model species in the study of ectomycorrhizal symbiosis Khasa et al. Additionally, the publication of what is phylogeny a level biology genome sequence of the ectomycorrhizal fungus, L. What are two types of symbiotic relationships in plant roots, the adaptation to local conditions reflects evolutionary processes in the plant-fungal symbiosis process under specific environmental conditions within the geographic distribution of both symbionts Hoeksema et al.

Species of Laccaria that have been used in mycorrhization processes are L. However, in previous works, the efficiency of sympatric versus allopatric species with Pinus hosts has not been experimentally tested. The ectomycorrhizal symbiosis is a tripartite partnership, where mycorrhizal helper bacteria MHB promote host colonization and enhance the symbiosis function Aspray et al. The MHB can promote mycorrhization in the bacteria-fungus-plant interaction.

However, in general the MHB favor the phase of pre-infection as they favour spore germination, mycelia growth through the soil, as well as an increase in the root susceptibility to mycorrhizal colonization. These effects have been demonstrated for Pseudomonas fluorescens in L. With the aim of producing native ectomycorrhizal inocula suitable for forest plants adapted to local conditions we selected the Trans-Mexican Volcanic Belt TMVB as a study model.

The TMVB is around 1, km length what are two types of symbiotic relationships in plant roots irregular amplitudes ranging between 80 and km. Pinus is the most diverse ectomycorrhizal host worldwide. Mexico is an important diversification center for Pinus Lamb. To test the hypothesis that the ectomycorrhiza becomes more efficient in terms of plant growth and nutrient content when a sympatric relationship between fungi and plants exists, we evaluated the mycorrhization effect on P.

We also tested the effect are there alot of fake profiles on tinder P. This species is naturally distributed between 2, and 3, m asl forming large woodland what are two types of symbiotic relationships in plant roots in the National Parks. Four Laccaria species that produce sporomes in great abundance were selected Garibay-Orijel et al.

Fruitbodies of L. There, the average altitude is 3, m, climate is temperate sub humid with annual average temperature of The main vegetation are conifer forests dominated by P. The main vegetation is constituted by mixed temperate Pinus-Quercus forests dominated by P. To know the concentration of spores in the inoculum of each species, we performed triplicate counts in a Neubauer chamber.

We also conducted spore viability tests following the protocol of Moreno-Martínez and Santiago-Martínez et al. We prepared 1 L of 1. We then counted the total number of metabolically active spores in a Neubauer Chamber. We acquired the MHB strain P. Seeds of P. We used a substrate composed of a mixture of peat and agrolite and mL containers. At the beginning of the experiment, each plant was inoculated with 10 7 spores placed in water solution added to the substrate.

Bacteria treatments included 0. All plants remained days in the greenhouse without any fertilization and watered with tap water every third day up to the saturation point; all treatments were randomly rotated every what are two types of symbiotic relationships in plant roots. The experimental design included 2 factors: 1 the ectomycorrhizal fungal species, including 4 levels L. We also included a treatment only with bacterial inoculum and a negative control without inoculum.

In total, the experiment had 10 treatments, with 13 seedlings each, comprising a total of experimental units, each one constituted by one plant. We determined total P, N and K content of the aerial and root parts for 5 randomly selected pines by treatment. The mycorrhization percentage in the root system for each seedling was randomly calculated. Evaluation of the mycorrhization effect and promotion by MHB on each response variable was conducted what does ddp include two-factor variance analysis.

When significant differences were obtained, we looked for the homogeneous groups by Tukey tests with the software Statistica 8 StatSoft ver. To describe the ectomycorrhizae morphology, we conducted the characterization of structures as proposed by Agerer Colors were recorded according to Kornerup and Wanscher The percentage of mycorrhization varied from Table 1 Growth, biomass accumulation and mycorrhization of Pinus montezumae inoculated with different Laccaria species and P.

The height of plants was similar among treatments. The remaining treatments produced heights ranging from The 3 variables used to evaluate biomass i. The best treatments were those inoculated with L. Laccaria trichodermophora treatments with or without bacteria had the second best total dry weight The control inoculated only with P. Significant differences were observed in the total P content between plants mycorrhized with L.

Mycorrhizal climate change financial risk act of 2021 inoculated with L. Total K of mycorrhizal plants with L. Table 2 Nutrient contents mg in Pinus montezumae inoculated with different Laccaria species and P. Mycorrhizae morphological description. The mantle presented reflective white patches over an orange base, it also showed emerging hyphae varying in quantity at the base and the apex.

Mantle plectenchymatous with palmate Hartig net widely distributed and with individual hyphae. Figure 1 Morphology of mycorrhizae formed between: Pinus montezumae, Laccaria spp. Cotton-like superficial mantle, with emerging hyphae in some parts, surrounding the apices. Mantle plectenchymatous with anastomosed hyphae in the middle parts.

Apex orange 5A6the rest of the mycorrhiza was brownish yellow 5E8. Cottony superficial mantle with emerging hyphae in certain parts; apex is mantle-free. Mantle pseudoparenchymatous, with palmate Hartig net widely distributed and showing individual hyphae. Cotton-like superficial mantle with rarely emanating hyphae. Mantle pseudoparenchymatous with palmate Hartig net widely distributed. Roots of P. All the inoculated plants developed mycorrhizas and mycorrhization percentages in all treatments what are two types of symbiotic relationships in plant roots high, greater than This is explained by the fact that the 4 Laccaria species used are ectomycorrhizal pine symbionts and all are native from Mexican forests as also is P.

As we will discuss later, the main differences found between sympatric and allopatric species are not evident in their ability to colonize the roots, but in their effect to improve the symbiosis efficiency. The mycorrhiza helper bacteria P. This contrasts with previous reported positive effects of P. In consequence, it might be expected that different strains exhibit a diverse spectrum of genetic traits involved in multi-trophic interactions with plants and other microbes Loper et al.

On the other hand, we demonstrate the efficiency of peat sterilization with Gamma rays, since both the negative control and the treatment with only P. Overall, we did not find significant differences in growth parameters, although pines mycorrhized with allopatric species were little higher and smaller root collar diameter than what are two types of symbiotic relationships in plant roots plants mycorrhized with sympatric species. The most important differences occurred in total biomass accumulation, as both sympatric species L.

Also, the increase in biomass accumulation in these treatments was independent of the presence of P. By comparison, allopatric species did not show any increase in biomass accumulation compared to the negative control. Regarding nutrient contents, we did what does background variable mean in research find a significant relationship between the plants N content, in any part of the plant, and the mycorrhization treatments.
