Specie di Trichoderma associate alla "muffa verde" di Pleurotus ostreatus.

2008

L’indagine è stata rivolta all’identificazione degli agen­ti di “muffa verde” in sacchi di substrato artificiale per la coltivazione di Pleurotus ostreatus. Inoltre, saggi indiretti di antagonismo, condotti impiegando il filtrato colturale di un ceppo di Acremonium byssoides, hanno mostrato una ri­levante attività di contenimento nei confronti dei differen­ti Trichoderma spp. agenti dell’alterazione e, nel contem­po, una scarsa efficacia nei confronti di alcune specie col­tivate di Pleurotus.

I pleuroti delle ombrellifere in Sicilia

2012

Gli Autori dopo avere evidenziato le problematiche tassonomiche del genere Pleurotus con particolare riferimento alle specie che fruttificano sui residui radicali delle ombrellifere entrano nel merito del caso di studio di Plerutous nebrodensis, specie rara ed a rischio di estinzione.

Up-to-date distribution, ecology and cultivation of Pleurotus eryngii (DC.) Quél. var. thapsiae Venturella, Zervakis & Saitta in Sicily

2012

Venturella et al. [1] described a new taxon named Pleurotus eryngii (DC.) Quél. var. thapsiae Venturella, Zervakis & Saitta (Madonie Mts) on Thapsia garganica L. and provided ecological data on the locus classicus. P. eryngii var. thapsiae was reported on pastures evolved, from 1000 to 1500 m a.s.l., on limestone and is characterized by a double period of fructification (autumn and spring). P. eryngii var. thapsiae is a choice wild edible mushroom belonging to a special group of Pleurotus species which appear in nature in close association with Apiaceae plants. As part of the project's census of fungi in Sicily two new localities of growth were localized in the Natural Reserves of Capo Gall…

The genus Pleurotus in Italy

2015

On the basis of personal observations, herbarium specimens and, data reported in the literature the authors report morphological, ecological and distributive data on Pleurotus taxa from Italy. New descriptions are here provided based on the most distinctive-discriminating eco-morphological characters of twelve Pleurotus taxa.

Late Pliocene and Pleistocene small mammal chronology in the Italian peninsula

2007

The abundant documentation of small mammals in the Italian peninsula, collected over recent years, furnishes a detailed biochronological sequence mainly from the Late Pliocene onwards. An updated stratigraphic framework is here presented, based on the European small mammal biozonation. The Early Villanyian is characterized by Mimomys hassiacus, M. stehlini, and, later, poorly documented M. polonicus. The Late Villanyian localities are well characterized with M. pliocaenicus, M. pitymyoides and M. tigliensis. The older part of the Early Biharian is documented by assemblages containing Microtus (Allophaiomys) ex gr. pliocaenicus, M. pusillus, M. cf. ostramosensis and M. tornensis, while the l…

Cadmium stress effects indicating marine pollution in different species of sea urchin employed as environmental bioindicators

2019

In recent years, researches about the defense strategies induced by cadmium stress have greatly increased, invading several fields of scientific research. Mechanisms of cadmium-induced toxicity continue to be of interest for researchers given its ubiquitous nature and environmental distribution, where it often plays the role of pollutant for numerous organisms. The presence in the environment of this heavy metal has been constantly increasing because of its large employment in several industrial and agricultural activities. Cadmium does not have any biological role and, since it cannot be degraded by living organisms, it is irreversibly accumulated into cells, interacting with cellular comp…

BBS1 Mutations in a Wide Spectrum of Phenotypes Ranging From Nonsyndromic Retinitis Pigmentosa to Bardet-Biedl Syndrome

2012

OBJECTIVE: To investigate the involvement of the Bardet-Biedl syndrome (BBS) gene BBS1 p.M390R variant in nonsyndromic autosomal recessive retinitis pigmentosa (RP). METHODS: Homozygosity mapping of a patient with isolated RP was followed by BBS1 sequence analysis. We performed restriction fragment length polymorphism analysis of the p.M390R allele in 2007 patients with isolated RP or autosomal recessive RP and in 1824 ethnically matched controls. Patients with 2 BBS1 variants underwent extensive clinical and ophthalmologic assessment. RESULTS: In an RP proband who did not fulfill the clinical criteria for BBS, we identified a large homozygous region encompassing the BBS1 gene, which carrie…

Toxic effects induced by vanadium on sea urchin embryos

2020

Vanadium, a naturally occurring element widely distributed in soil, water and air, has received considerable interest because its compounds are often used in different applications, from industry to medicine. While the possible medical use of vanadium compounds is promising, its potential harmful effects on living organisms are still unclear. Here, for the first time, we provide a toxicological profile induced by vanadium on Paracentrotus lividus sea urchin embryos, reporting an integrated and comparative analysis of the detected effects reflecting vanadium-toxicity. At the morphological level we found a dose-dependent induction of altered phenotypes and of skeletal malformations. At the mo…
