Resumen:
Eragrostis curvula is a grass species that is being studied in order toidentify the genes and genomic regions involved in apomixis, an asexualmode of reproduction that avoid meiosis (apomeiosis) and fertilization ofthe egg cell and develops an embryo by parthenogenesis. Transferringapomixis to economically important crops will revolutionize the agricultureas we know it today since it can fix the hybrid vigor for generations. Theidentification of genomic regions associated to this trait and its regulatorycomponents is central to transfer apomixis to other crops. In this way, wealready sequenced a sexual diploid genotype, however, more complexapomictic tetraploids are necessary to perform comparative analyses.The tetraploid genome of the apomictic genotype Don Walter (2n=4x=40,~1200 Mb) was sequenced using a combination of technologies to obtaina chromosome scale assembly. We used 10x genomic reads that wereassembled with supernova software
