AKNOWLEDGMENTSA special acknowledgment to Prof. Tsai Siu Mui, whose enthusiasm, advisory, innovative character, brilliancy and strength has encouraged me to go through all the steps of this project.A friend, a person willing to talk to you anytime… Much more to say, but let's keep it humble as she is! Thank you.My gratitude to Prof. Paul Gepts for his valorous advice and encouragement during all this period, especially for the wonderful opportunity that I had while working at UC-Davis, in California.To Prof. Beatriz Madalena Januzzi Mendes for all support during the first year.My special thank you to Gustavo Henrique Recchia and Fernanda Cassieri. They were always outstanding, helping in every single experiment from the very beginning. Nós sempre estávamos meio 'perdidos' com tantas coisas a serem feitas!!!! And not only speaking of science, they are great friends that gave me motivation to go ahead on all the steps to be taken during these years. I really couldn't miss this space to describe how much I am thankful to you guys.A very special acknowledgment to Jorge Carlos Berny and Viviana Medina, my California science and happy hour mates. I can't tell how much I've learned from you and how much fun we've been having together. From the LICOR afternoons in the hot Davis fields to the labeling lab nights…guys, thank you so much for being part of this thesis and my life.Amaaaaaaaaaaaaaazing! Takatakatakataka! I will always be visiting around, you know that for sure.The financial support of FAPESP scholarship (process 2011-12.484-7) and from the Science Without Borders program from CNPq (process 249992/2013-2) were essential and without them this work would not have been accomplished. I extend this acknowledgment to CAPES, USDA, BeanCAP and California Bean Advisory BoardThanks to all BIOMOL/CENA lab mates: Acacio, Aline, Andressa, Bia, Caio, Carol, Clóvis, Danielle, Dennis, Fabi, Felipe, Fernanda Nakamura, Jonathas, Juliane, Leandro, Lucas Mendes, Lucas Palma, Ludmila, Maju, Marília, Marina, Nayara, Rosineide.Thanks to all California lab mates: Amanda, Andrea, Antonia, Arthur, Erin, Kay, Jamily, Karla, Laura, Manisha, Ninh, Paige, Regina, Sarah Dohle, Saarah Kuzay, Tamara, Travis, Vanessa. I had such a nice time and learned a lot from you guys. Thanks to all the friends from California. Baris and Dawit, thanks for all the laughing and happy moments. Raul, Stefano, Ziv, Angel, Jaime, Andrés, Syed… I will never forget the precious dinners and trips we had together has housemates. A special thank you to StephanieTrasher for her hospitality, integrity and friendship. I appreciate every moment spent in California with all of you. Common bean is a major dietary component in several countries, but its productivity is negatively affected by abiotic stresses. Dissecting candidate genes involved in abiotic stress tolerance is a paramount step toward the improvement of common bean performance under such constraints. Thereby, this thesis presents a systematic analysis of the DEHYDRATION RESPONSIVE ELEMENT-BINDING (DREB) gene ...

“…CPSF binds the PAS, so the reduced polyadenylation efficiency is due to weakened binding of CPSF (Chan et al, 2011). The C-allele is associated with various cancer diseases (Stacey et al, 2011; Zhou et al, 2012). This polymorphism could be important for endocrine tumor diseases as well, as loss of p53 is an important event in the pathogenesis of many tumors, e.g., thyroid tumors (Yoshimoto et al, 1992).…”

Introduction: Polyadenylation is the process in which the pre-mRNA is cleaved at the poly(A) site and a poly(A) tail is added – a process necessary for normal mRNA formation. Genes with multiple poly(A) sites can undergo alternative polyadenylation (APA), producing distinct mRNA isoforms with different 3′ untranslated regions (3′ UTRs) and in some cases different coding regions. Two thirds of all human genes undergo APA. The efficiency of the polyadenylation process regulates gene expression and APA plays an important part in post-transcriptional regulation, as the 3′ UTR contains various cis-elements associated with post-transcriptional regulation, such as target sites for micro-RNAs and RNA-binding proteins.Implications of alterations in polyadenylation for endocrine disease: Alterations in polyadenylation have been found to be causative of neonatal diabetes and IPEX (immune dysfunction, polyendocrinopathy, enteropathy, X-linked) and to be associated with type I and II diabetes, pre-eclampsia, fragile X-associated premature ovarian insufficiency, ectopic Cushing syndrome, and many cancer diseases, including several types of endocrine tumor diseases.Perspectives: Recent developments in high-throughput sequencing have made it possible to characterize polyadenylation genome-wide. Antisense elements inhibiting or enhancing specific poly(A) site usage can induce desired alterations in polyadenylation, and thus hold the promise of new therapeutic approaches.Summary: This review gives a detailed description of alterations in polyadenylation in endocrine disease, an overview of the current literature on polyadenylation and summarizes the clinical implications of the current state of research in this field.

Elucidation of Abiotic Stress Signaling in Plants

Nature provides all necessary components for healthy growth and development of plants in the form of air, water, light, nutrients, and soil. Any imbalance in the environmental harmony may cause stress to them. Stresses encountered by plants can broadly be categorized into biotic and abiotic stresses. Biotic stresses are mainly caused by pathogens and herbivory, whereas abiotic stresses include the threat imposed by drought, salinity, and extremes of temperature, heavy metals, and pollution. Drought stress is a major cause of yield instability in crops across diverse eco-geographic regions worldwide. A variety of biochemical, molecular, and physiological changes are manifested by plants in response to drought stress. The cellular abscisic acid (ABA) concentration increases on water defi cit leading to the activation of a number of stress-responsive genes and the patterns of expression of these genes are very complex, with some genes being induced early while others respond slowly. In general, drought-responsive genes respond to salt and cold stresses as well as to exogenous ABA treatment. However, there are several genes, which express themselves in an ABA-independent manner suggesting that both ABAdependent and -independent signal transduction cascades exist for drought stress perception, response, and adaptation. Drought stress response and adaptation in plants involves an array of pathways for signal perception, transduction, gene expression and synthesis of proteins, and other stress metabolites. Droughtresponsive genes can mainly be classifi ed into two groups. First group constitutes genes whose products provide osmotolerance and protection to plants thus directly functioning in tolerance to stress, while the second group includes genes playing a role in signal transduction as well as regulation of gene expression. This chapter summarizes the complex molecular mechanisms of drought stress response and adaptation in plants, highlighting the transcriptional regulation of stress-responsive
