Dystroglycan regulates structure, proliferation and differentiation of neuroepithelial cells in the developing vertebrate CNS.

2007

AbstractIn the developing CNS α- and β-dystroglycan are highly concentrated in the endfeet of radial neuroepithelial cells at the contact site to the basal lamina. We show that injection of anti-dystroglycan Fab fragments, knockdown of dystroglycan using RNAi, and overexpression of a dominant-negative dystroglycan protein by microelectroporation in neuroepithelial cells of the chick retina and optic tectum in vivo leads to the loss of their radial morphology, to hyperproliferation, to an increased number of postmitotic neurons, and to an altered distribution of several basally concentrated proteins. Moreover, these treatments also altered the oriented growth of axons from retinal ganglion c…

Chromogenic detection of nerve agent mimics

2008

The current rise in international concern over criminal terrorist attacks via chemical warfare (CW) agents has resulted in an increasing interest in the detection of these lethal chemicals. Among CW species, nerve agents are extremely dangerous and their high toxicity and ease of production underscore the need to detect these deadly chemicals via quick and reliable procedures. A number of detection systems have been developed, most of them based on enzymatic and physical methodologies. However, these usually show limitations such as low selectivity, lack of portability and a certain complexity in their use. An alternative to these classical methods that has been gaining interest in recent y…

Mycoforestry in Sicily: a proposal to enhance the multifunctionality of forests

2017

Mycoforestry is forestry that aims to build on traditional rules to encourage forest ecosystem resilience while creating optimal conditions for fungal communities. Main goals of mycoforestry are: preservation of native forests, recovery and recycling of woodland debris, enhancement of replanted trees, strengthening sustainability of ecosystems, economic diversity. There is a large variety of fungi living in forests, each of which has a specific and complementary relationship to the diversity of native species, the ages of trees, the presence of dead trees or rich forest litter, etc. Fungi are the main responsible of wood decomposition and thus carbon and nutrient cycling, and they also form…

The occurrence of mycorrhizal fungi in Betula aetnensis Raf. roots: from ecological role to conservation strategies

2017

Betula aetnensis Raf. is an endemic tree species of particular conservation value. It only thrives in the north-eastern slopes of Mount Etna (Sicily), from 1200 to 2100 m a.s.l. This pioneer plant is able to begin primary succession on nutrient-poor and water-limited soils (C = 0.17%; N = 0.05 ‰; P2O5 = 4.1 ppm), where beneficial mycorrhizal fungi (MF) may play a crucial role. In order to investigate MF role in B. aetnensis, plant roots from natural sites and nursery grown specimens were analyzed for both ectomycorrhizal and endomycorrhizal structures. Typical structures of both symbiosis were detected by root staining and morphological observations. Ectomycorrhizae (EM) were more abundant …

Phylogenetic diversity and affiliation of tropical African ectomycorrhizal fungi

2022

Ectomycorrhizal fungi form a mutualistic symbiosis with plant roots, and are key for nutrient cycling in many ecosystems. Here we study the ectomycorrhizal fungal communities in the Oueme Superieur reserve forest in Benin (West Africa). We use phylogenetic methods to test if the species from the study site are closer to other tropical African species than to species from other regions. The Oueme Superieur community was represented by nine Operational Taxonomic Units in Amanitaceae, one in Boletaceae, one in Cantharellaceae, one in Cortinariaceae, two in Inocybaceae, fourteen in Russulaceae and three in Sclerodermataceae. Of these thirty-one Operational Taxonomic Units, twenty had no record …

2016

Following their evolutionary process, many plants have oriented their secondary metabolism towards the production of complex molecules, which often show an apparent protective function against pests (insects, fungi, viruses, but also competing plants). The identification and the study of such compounds could play a significant role in the frame of the development of new techniques for sustainable plant protection, where they could help in achieving the goal of a reduction in the use of the most highly-impact chemicals. The Mediterranean basin, with its very large biodiversity, represents a huge reservoir of highly promising plant material, which is scarcely explored as far. Indeed, prelimin…
