Resumen: DELLA proteins are land-plant speci%c transcriptional regulators that transduce environmental information to multiple processes throughout a plant’s life. The molecular basis for this critical function in angiosperms has been linked to the regulation of DELLA stability by gibberellins and to the capacity of DELLA proteins to interact with hundreds of transcription factors (TFs). However, it is not clear whether this promiscuity is an ancestral property of DELLA proteins or it is associated with their role in gibberellin signaling. We have found that representative DELLAs from the main plant lineages display a conserved ability to interact with multiple TFs. However, we have detected an extensive diversi%cation in the output target genes and biological processes regulated by these interactions, by comparing the DELLA-dependent transcriptomes across different land-plant lineages. We propose that promiscuity was already encoded in the ancestral DELLA protein, and that this molecular property has been largely maintained, while the lineage-dependent diversi%cation of DELLA- dependent biological functions mostly re#ects the functional evolution of their interacting partners.

Resumen: Cytokinesis is the physical process of cell separation in the cell division, in which the cytoplasm of a parental eukaryotic cell divides into two daughter cells. The cytoskeleton is crucial to carry out the cytokinesis. shrub encodes a filament-forming subunit of ESCRT-III (Endosomal Sorting Complex Required for Transport) essential in the cell abscission, the last step of cytokinesis. In female germline stem cells of Drosophila melanogaster, shrub controls the timing of cell division by recruiting ESCRT-III complex in the midbody before the abscission and its absence stops germinal stem cells division. The current knowledge of the function of shrub in insect oogenesis is limited to germinal stem cells, and its role in ovarian somatic cells is still unknown. Our objective is to unveil the function of shrub in the oogenesis of adult cockroaches of Blattella germanica using RNA interference (RNAi). Experiments were performed injecting freshly emerged adult females with double-strand RNA (dsRNA) against shrub and dissecting insects at day 5.
