Vesicular-arbuscular mycorrhizal infection of lucerne roots in a cellulose-amended soil.
No full textLucerne plants inoculated with vesicular-arbuscular mycorrhizal fungi were grown in pots in a sandy soil amended or not amended with cellulose. Whatever the endophyte or cellulose sources used, the rate of VAM colonization was lower in amended soil. The inhibition of VAM infection increased with the cellulose concentration in the soil. Sequential harvest experiments showed a clear reduction of root colonization from the early stages of plant growth. The effectiveness of cellulose in reducing VAM colonization was influenced by the addition of N fertilizer
The protein pattern of spores of arbuscular mycorrhizal fungi: comparison of species, isolates and physiological stages
No full textSpore proteins of different species and isolates of arbuscular mycorrhizal (AM) fungi were compared by PAGE. Reproducibility of protein patterns was assessed by using cultures of the same species either grown on different host plants, or produced during successive propagation cycles and stored up to 5 years. The results consistently showed that host species, different generations and storage, did not affect protein profiles, thus validating the accuracy of the method. Comparison among different geographical isolates of the same species revealed consistent protein patterns. The stability and diversity of spore protein profiles suggested that PAGE could be used to discriminate and identify AM fungal species and isolates. By contrast, the physiological state of spores affected the quality and quantity of bands, with germinating spores showing marked profile changes, as compared to quiescent spores, both in denaturating and native analytical conditions. The disappearance of some polypeptides in germinated spores might be related to the occurrence of storage proteins in AM fungi
Diritto di critica e obblighi di riservatezza [Right of criticism and duty of confidentiality]
No full textLa recente legge sul whistleblower, estendendo la fattispecie ai lavoratori del settore privato, interviene indirettamente sulla velata questo dei limiti al diritto di critica del lavoratore, potendo, secondo questo contributo, portare a una radicale modifica dell'attuale interpretazione prevalente.The author outlines the limits to the right of criticism defined through case law. A particular attention is devoted to the balancing of right of criticism and duty of confidentiality and to the role of the right of criticism on the prevention of corruption. Then, he analyses the new legislation on whistle-blowers. The objective of the paper is that of re-thinking, on the basis of the whistle-blowers legislation, the boundaries of the right to criticism so as to make them more respondent to the values of the Italian Constitution
Dalla produttività alla performance individuale
No full textAnalisi del concetto di performance e valutazione della performance alla luce dei d.lgs 74 e 75 del 2017: l'autore ritiene che la nuova legislazione conduce ad un sistema nel quale la misurazione della performance individuale del personale non dirigente diventa il nuovo metro per verificare l'adempimento della prestazione dedotta in contratto.The essay analyses the concept of performance used in legislative decrees No. 74 and 75 of 2017, which reform the employment relation in public administrations. The Author takes into consideration the concepts of productivity and efficiency used in the past reforms. Then he compares the 2009 reform concept of performance with that of the present day reform. The findings are those of an important evolution in the use of the concept of performance, which is nowadays widely utilized
