“…The occurrence of AM fungi in these families agrees with the reports of Harley and Harley [40], Newman and Reddell [63], Godoy et al [37], and Zhao [86]. The presence of the Paristype predominates in ferns [76].…”

-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

“…Some plant families are still assumed to never or rarely form mycorrhizal associations (Newman and Reddell 1987;Tester et al 1987), such as members of the Cyperaceae, Brassicaceae, Caryophyllaceae, Juncaceae, and Amaranthaceae (Smith and Read 1997). The AM status of Cyperaceae was found to vary in different habitats of China.…”

The biodiversity and distribution of arbuscular mycorrhizal fungi (AMF) in different ecosystems and plant communities in China has received increasing interest over the past decades. This has led to a steady increase in the number of scientific papers published on this topic. Studies have surveyed AMF-colonizing rhizospheres of most families of angiosperms, bryophytes, pteridophytes, and gymnosperms. China has about 30,000 plant species (one eighth of the plant species worldwide). A total of 104 AMF species within nine genera, including 12 new species, have been reported in environments such as croplands, grasslands, forests, and numerous disturbed environments. In this paper, we review data published over the past 20 years on AMF community composition and species distribution, the mycorrhizal status of plants, AMF spore communities in different habitats, and germplasm collections in China. Possible future trends in the study of the biodiversity of AMF are also briefly discussed. In particular, the aim of our review is to make some of the recent work published in the Chinese literature accessible to a wider international audience.

“…The complex cellular relationship between host roots and arbuscular mycorrhizal (AM) fungi requires a continuous exchange of signals (reviewed by Vierheilig et al, 1998) which leads to the development of specific AM fungal structures in the roots of host plants. Most higher plants are able to form AM symbiosis with fungi of the order Glomales ; however there are contradictory reports about the mycorrhizal status of plants in the Brassicaceae (Medve, 1983 ;Harley & Harley, 1987 ;Newman & Reddell, 1987 ;Koide & Schreiner, 1992). In general the Brassicaceae are known as AM non-host plants, however recent papers report AM colonization in wild crucifers including Capsella bursa-pastoris, Coronopus didymus, Hesperis matronalis, Matthiola incana and Sisymbrium irio (DeMars & Boerner, 1994, 1995Kapoor et al, 1996).…”

“…The colonization by AM fungi of glucosinolatecontaining plant species such as certain Brassica and Reseda species has been reported ; however a functional mycorrhizal association has never been proven (Medve, 1983 ;Harley & Harley, 1987 ;Newman & Reddell, 1987 ;Tester et al, 1987 ;Koide & Schreiner, 1992). Most studies have been performed on field material where the unequivocal identification of individual fungi is often difficult unless arbuscules and vesicles are formed (Harley & Harley, 1987 ;Tester et al, 1987) and therefore hyphae attributed to AM fungi might in fact be those of nonmycorrhizal fungi (DeMars & Boerner, 1995).…”

Differences in glucosinolate patterns and arbuscular mycorrhizal status of glucosinolate‐containing plant species

et al. 2000

Under defined laboratory conditions it was shown that two glucosinolate-containing plant species, Tropaeolum majus and Carica papaya, were colonized by arbuscular mycorrhizal (AM) fungi, whereas it was not possible to detect AM fungal structures in other glucosinolate-containing plants (including several Brassicaceae). Benzylglucosinolate was present in all of the T. majus cultivars and in C. papaya it was the major glucosinolate. 2-Phenylethylglucosinolate was found in most of the non-host plants tested. Its absence in the AM host plants indicates a possible role for the isothiocyanate produced from its myrosinase-catalysed hydrolysis as a general AM inhibitory factor in non-host plants. The results suggest that some of the indole glucosinolates might also be involved in preventing AM formation in some of the species. In all plants tested, both AM hosts and non-hosts, the glucosinolate pattern was altered after inoculation with one of three different AM fungi (Glomus mosseae, Glomus intraradices and Gigaspora rosea), indicating signals between AM fungi and plants even before root colonization. The glucosinolate induction was not specifically dependent on the AM fungus. A time-course study in T. majus showed that glucosinolate induction was present during all stages of mycorrhizal colonization.
