El present treball analitza al microscopi òptic i al microscopi electrònic de transmissió el testicle de Sus domesticus (raça Landrace - varietat anglesa) a partir de mascles reproductors porcins adults i sans. L'objectiu ...
Estudi d'una metal·lotioneïna d'alzina surera (QsMT)
Mir Arnau, Gisela (Date of defense: 2005-05-09)
En aquest treball es caracteriza per primera vegada la capacitat de coordinació metàl·lica d'una metal·lotineïna (MT) de planta i es proposa un model de plegament per a les MTs de planta en general. Els resultat mostren ...
Identificació de gens i processos rellevants pel fel·lema i la suberina usant noves aproximacions
Fernández Piñán, Sandra (Date of defense: 2018-04-13)
The periderm is a complex structure that protects plants’ secondary organs and wounded tissues. This function is given by the phellem, a multilayered tissue formed by cells with suberized cell walls located on the outer ...
Microbial communities responses in fluvial biofilms under metal stressed scenarios
Argudo Fernández, Maria (Date of defense: 2021-02-08)
This thesis shows how the metals of natural and anthropic origin change significantly the composition of the prokaryotic communities (mainly the composition of bacteria). The β-diversity is the most sensitive variable to ...
