PhD thesis of Erica Mica (BIO/11) CHARACTERIZATION OF miRNA FAMILIES IN Zea mays L. AND Arabidopsis thaliana. In this manuscript are collected the results of my analyses about the characterization of miRNAs from Z. mays (maize), one of the most important crops in the world. To further analyze some aspects of the miRNAs characterized in maize, it was considered the model plant A. thaliana (Arabidopsis) that allows deeper molecular investigation. The manuscript is divided into three sections: - the first one is a general introduction, in the form of a review, on the small RNA world, with particular interest on miRNA. - the second one is reported as it was published on Journal of Experimental Biology, in 2006 (Mica et al., 2006).
