Since we were able to establish the Xenopus laevis experimental model in Brazil, we have been focused on understanding early embryonic patterns regarding neural induction and axes establishment. In this context, the Wnt pathway appears as a major player and has been much explored by us and other research groups. Here, we chose to review three published works which we consider to be landmarks within the course of our research and also within the history of modern findings regarding neural induction and patterning. We intend to show how our series of discoveries, when painted together, tells a story that covers crucial developmental windows of early differentiation paths of anterior neural tissue: 1. establishing the head organizer in contrast to the trunk organizer in the early gastrula; 2. deciding between neural ectoderm and epidermis ectoderm at the blastula/gastrula stages, and 3. the gathering of prechordal unique properties in the late gastrula/early neurula.","PeriodicalId":50329,"journal":{"name":"International Journal of Developmental Biology","volume":"65 4-5-6","pages":"227-233"},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38380169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This phenotypic plasticity enables an organism to adapt to changes in the environment by responding with different phenotypes. The gonad and the brain present this extraordinary plasticity. These organs are involved in the response to environmental stressors to direct gonadal fate, inducing sex change or sex reversal in hermaphroditic and gonochoristic fish, respectively. The presence of such molecular and endocrine plasticity gives this group a large repertoire of possibilities against a continuously changing environment, resulting in the highest radiation of reproduction strategies described in vertebrates. In this review, we provide a broad and comparative view of tremendous radiation of sex determination mechanisms to direct gonadal fate. New results have established that the driving mechanism involves early response to environmental stressors by the brain plus high plasticity of gonadal differentiation and androgens as by-products of stress inactivation. In addition to the stress axis, two other major axes - the hypothalamic-pituitary-gonadal axis and the hypothalamic-pituitary-thyroid axis, which are well known for their participation in the regulation of reproduction - have been proposed to reinforce brain-gonadal interrelationships in the fate of the gonad.","PeriodicalId":50329,"journal":{"name":"International Journal of Developmental Biology","volume":"65 4-5-6","pages":"207-214"},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1387/ijdb.200072jf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38380586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These molecules and networks have gained recognition as fundamental players in mechanisms that regulate the development of multicellular organisms. First, we present a brief review in which we provide a historical description of some relevant discoveries that led to this recognition. We also discuss the fact that, despite its abundance in nature, oxygen is a limiting factor, and its high availability variation impacted the evolution of adaptive mechanisms to guarantee the proper development of diverse species under such extreme environments. Finally, some examples of when oxygen and ROS were identified as relevant for the control of developmental processes are discussed. We take into account not only the current knowledge on animal redox developmental biology, but also briefly discuss potential scenarios on the origin and evolution of redox developmental mechanisms and the importance of the ever-changing environment.","PeriodicalId":50329,"journal":{"name":"International Journal of Developmental Biology","volume":"65 4-5-6","pages":"345-356"},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38382567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Casual events and serendipity played important roles in modeling her career as a developmental biologist. In collaboration with colleagues and students, she analyzed the biology and development of the marsupial frog Gastrotheca riobambae (family: Hemiphractidae) in comparison with Xenopus laevis and tropical frogs. The emphasis was placed on oogenesis and the early stages of development. Topics include the mono- and multi-nucleated modes of oogenesis. She described two modes of gastrulation in frogs, gastrulation modes one and two, according to the timing of notochord elongation. She was able to establish a pioneer laboratory for the comparative analysis of frog development in Ibero America at the Pontifical Catholic University of Ecuador, in Quito. Her contributions to society include her influence in the establishment of the National Academy of Sciences of Ecuador, and efforts toward the conservation of the Galápagos Archipelago. She is part of a pioneer group of professors that placed Biology as an academic discipline in Ecuador. The experiences of her career reveal that we all face difficulties in our jobs. However, nothing is impossible when we follow a passion. Her work reveals that the key to success is to turn obstacles into opportunities.","PeriodicalId":50329,"journal":{"name":"International Journal of Developmental Biology","volume":"65 1-2-3","pages":"103-110"},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1387/ijdb.190351ed","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38277755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite being new, this society already had a highly important impact on the advancement of Developmental Biology across Latin America and globally. From its conception, the society began with the establishment of courses and congresses at the frontiers of knowledge and with the participation of researchers from Latin American countries and other regions, creating an academic and fraternal environment. The first LASDB congress was held in 2003, and recently, in 2019, the LASDB celebrated its tenth meeting, besides the Pan-American congress organized in 2007. Since the creation of this society and throughout its consolidation, the LASDB has been fortunate in receiving the support of highly prominent Developmental Biology societies, with which it has established links and collaboration that have clearly promoted Development Biology not only in Latin America but also in other parts of the world. At this moment, the LASDB looks to the future to continue supporting science in Latin America as it has done up to the present.","PeriodicalId":50329,"journal":{"name":"International Journal of Developmental Biology","volume":"65 1-2-3","pages":"77-81"},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1387/ijdb.200019mz","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38277756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
