In this Master's Thesis, we have contributed to the functional characterization of the DNA POLYMERASE V (POL5), RIBOSOMAL RNA PROCESSING 36 (RRP36), U THREE PROTEIN 18 (UTP18), UTP22, and BMh SENSITIVE 1 (BMS1) genes in Arabidopsis thaliana, whose orthologs in Saccharomyces cerevisiae encode proteins that are part of the SSU processome, involved in ribosomal RNA (rRNA) 18S maturation and assembly of the small ribosomal subunit or 40S. The effects of the partial inactivation of these genes have been analysed in several amiR-POL5, amiR-RRP36, amiR-UTP18, and amiR-UTP22 lines, carrying transgenes expressing artificial microRNAs (amiR lines) that were generated in the laboratory prior to the start of this work. Additionally, we have initiated the functional analysis of the BMS1 gene by analyzing the denticulata9 (den9) mutant and two insertional lines that disrupt it. The morphological and molecular phenotypes of plants of several amiR lines and den9 suggest that Arabidopsis POL5, RRP36, UTP18, UTP22, and BMS1 proteins are also involved in ribosome biogenesis, acting in the maturation of 18S rRNA, similar to their yeast orthologs.
