“…This variation of the Paris-type mycorrhizas has also been described by Gerdemann [33] and Bedini et al [9]. The Paris-type was seen to be dominant in the herbaceous understory plants of the NOA, similar results were found by Yamato and Iwasaki [85] for herbaceous plants of the forests of the Kansai region. These facts indicate that the Paris-type is advantageous for herbaceous understory plants that grow slowly with low light intensity and low nutrient availability levels.…”

-In Argentina, the Yungas forests are among the ecosystems most affected by human activity, with loss of biodiversity. To assess the mycorrhizal status in these ecosystems, the roots of 41 native plant species belonging to 25 families were collected throughout the year from two sites of the Yungas forests. Roots were washed and stained to study the presence of arbuscular mycorrhizas (AM). Morphological types of arbuscular mycorrhizas (Arum and Paris-type) and colonization patterns were identified and photographed. All plants presented AM colonization. The AM colonization patterns varied from single intracellular aseptate hyphae, coils, appresoria, to vesicles and/or arbuscules. Among the species studied, the Paris-type colonization showed to be dominant. Results confirmed that AM hosts are predominant in the Yungas of South American forests.Yungas / arbuscular mycorrhizal / Arum-type / Paris-type / Alnus forests Résumé -Colonisation par les mycorhizes arbusculaires dans des plantes vasculaires des forêts des Yungas, Argentine. En Argentine, les Yungas constituent un des écosystèmes les plus atteints par l'activité de l'homme, avec la perte de biodiversité qui en découle. Pour évaluer le statut mycorhizien de ces écosystèmes, les racines de 41 plantes autochtones appartenant à 25 familles ont été collectées au cours de l'année dans deux sites des forêts des Yungas. Les racines ont été lavées et teintes afin de déterminer la présence des mycorhizes arbusculaires (MA). Les types morphologiques de MA (type Arum et Paris) et les patrons de colonisation ont été identifiés et photographiés. Toutes les plantes ont présenté une colonisation MA. Les structures fongiques intraracinaires comprenaient des hyphes intracellulaires sans cloison, des boucles, des appressoria, des vésicules et/ou des arbuscules. Le type de colonisation Paris est apparu comme dominant parmi les espèces étudiées. Les résultats confirment que les hôtes avec MA prédominent dans les forêts sudaméricaines des Yungas.Yungas / mycorhizes arbusculaires / type Arum / type Paris / bois d'Alnus

Resumo -O objetivo do presente trabalho foi comparar a infecção micorrízica e indicadores de qualidade das mudas de Calophyllum brasiliense e Anandenanthera colubrina var. cebil procedentes do Bioma Pantanal, desenvolvidas em substrato não fumigado e sob inoculação combinada com Glomus clarum (Gc) + Gigaspora margarita (Gm). Mudas das duas espécies produzidas em condições de viveiro foram aleatoriamente selecionadas e avaliadas quanto a parâmetros de qualidade morfológica, percentual, intensidade e morfologia da colonização micorrízica de raízes finas. Concluiu-se que, sob as condições de estudo, a inoculação com Gc + Gm promove mudanças no percentual, na intensidade (A. colubrina var. cebil) ou na morfologia (C. brasiliense) da infecção radicular, quando comparadas com mudas não-inoculadas. Incremento em parâmetros de qualidade das mudas foi observado em C. brasiliense sob inoculação combinada (Gc + Gm), apontando o potencial de uso de fungos micorrízicos na produção desta espécie. Seedlings quality of tree species from Pantanal Wetland Biome, inoculated with mycorrhizal fungiAbstract -The aim of this study was to compare mycorrhizal infection and quality indicators of Calophyllum brasiliense and Anandenanthera colubrina var. cebil seedlings from Pantanal Wetland Biome, Brazil, produced in non-fumigated substrate under combined inoculation with Glomus clarum (Gc) + Gigaspora margarita (Gm). Seedlings were produced from seeds of local populations seeds, inoculated and noninoculated with Gc + Gm. They were randomly selected and evaluated for morphological quality parameters, percentage, intensity and morphology of mycorrhizal colonization of fine roots. We concluded that, under the study conditions, Gc + Gm inoculation promotes changes in the percentage, intensity (A. colubrina var. cebil) or morphology (C. brasiliense) of root infection when compared to non-inoculated seedlings. Increase in quality of seedlings was observed in C. brasiliense under combined inoculation with Gc + Gm, indicating the potential of mycorrhizal fungi use in this specie.

“…Brundrett & Kendrick (1990) indicated that the presence or absence of intercellular air spaces in the root cortical region to be an important determinant of AM morphology. Later studies elaborated this view and speculated the influence of factors like light, moisture and temperature of the substrates on AM patterns in roots as these factors can influence root growth (Yamato & Iwasaki 2002;Yamato 2004;Becerra et al 2007). However, detailed studies exploring root anatomy of lithophytic plant species, especially the intercellular spaces in roots could reveal their contribution to AM morphology.…”

Root fungal associations in some non-orchidaceous vascular lithophytes

Plant roots in natural ecosystems are colonized by a diverse group of fungi among which the most common and widespread are arbuscular mycorrhizal (AM) and dark septate endophyte (DSE) fungi. Th ough AM and DSE fungal associations are well reported for terricolous plant species, they are rather poorly known for lithophytic plant species. In this study, we examined AM and DSE fungal association in 72 non-orchidaceous vascular plant species growing as lithophytes in Siruvani Hills, Western Ghats of Tamilnadu, India. Sixty-nine plant species had AM and 58 species had DSE fungal associations. To our knowledge, we report AM fungal association in 42 and DSE fungal association in 53 plant species for the fi rst time. Th ere were signifi cant diff erences in total root length colonization and root length colonized by diff erent AM and DSE fungal structures among plant species. In contrast, the diff erences in AM and DSE fungal colonization among plants in various life-forms and lifecycles were not signifi cant. AM morphology reported for the fi rst time in 56 plant species was dominated by intermediate type AM morphology. A signifi cant negative relationship existed between total root length colonized by AM and DSE fungi. Th ese results clearly suggest that AM and DSE fungal associations are widespread in lithophytes.
