Abstract
The Lentibulariaceae belongs to the richest carnivorous plants families and therefore grouped into 320 species arranged in three genres: Pinguicula, Genlisea and Utricularia. Recent phylogenetic and comparative studies indicated that the Lentibulariaceae are positioned at the Lamiales order, but their relationships within different families are still under discussion. The family is monophyletic, whereas the clade Genlisea-Utricularia considered a sister-group of Pinguicula. Amid these three genera, Utricularia is the richest, showing high morphological differences. Among all species of carnivorous syndrome, Utricularia match about 35% of the taxa. Moreover, several species have dubious circumscription, and there are few studies for neotropical species. Indeed studies involving the molecular genetics of this group are limited. Recently, in the middle of 2013, the complete genome sequences of the worldwide endemic specie U. gibba were sequenced, and this study determined that this specie has one of the smallest known plant genome (80Mb). Therefore, the purpose of this project is to study the U. reniformis, which is endemic to Brazil, through an genomic, functional and evolutionary approaches. To achieve this objective, four main goals are presented: (i) Whole genome sequencing and annotation of the brazilian endemic specie U. reniformis; (ii) Perform a comparative genomics studies against the species U. gibba with ecological and systematic approaches, since U. reniformis is terrestrial and U. gibba is aquatic; (iii) Whole transcriptome sequencing of the carnivory related tissue (utricles) with and without the presence of the preys, in order to investigate transcripts/genes related to the digestive process; (iv) Evaluate the evolution and morphogenesis by comparatice approaches of different tissues through the transcriptome sequencing of leaves and utricules. This project presents great importance to the understanding of genomic, evolutive and functional aspects of U. reniformis, which may, with the next-generation sequencing and computational biology approaches shed light to a better understanding not only for the biology and evolution of Utricularia genus, but also for other genera and lineages of the Lentibulariaceae family.
