Phytochemistry, Pharmacology and Agronomy of Medicinal Plants: Amburana Cearensis, an Interdisciplinary Study
17 Phytochemistry, Pharmacology and Agronomy of Medicinal Plants: Amburana cearensis, an Interdisciplinary Study Kirley M. Canuto, Edilberto R. Silveira, Antonio Marcos E. Bezerra, Luzia Kalyne A. M. Leal and Glauce Socorro B. Viana Empresa Brasileira de Pesquisa Agropecuária, Universidade Federal do Ceará, Brazil 1. Introduction Plants are an important source of biologically active substances, therefore they have been used for medicinal purposes, since ancient times. Plant materials are used as home remedies, in over-the-counter drug products, dietary supplements and as raw material for obtention of phytochemicals. The use of medicinal plants is usually based on traditional knowledge, from which their therapeutic properties are oftenly ratified in pharmacological studies. Nowadays, a considerable amount of prescribed drug is still originated from botanical sources and they are associated with several pharmacological activities, such as morphine (I) (analgesic), scopolamine (II) atropine (III) (anticholinergics), galantamine (IV) (Alzheimer's disease), quinine (V) (antimalarial), paclitaxel (VI), vincristine (VII) and vinblastine (VIII) (anticancer drugs), as well as with digitalis glycosides (IX) (heart failure) (Fig. 1). The versatility of biological actions can be attributed to the huge amount and wide variety of secondary metabolites in plant organisms, belonging to several chemical classes as alkaloids, coumarins, flavonoids, tannins, terpenoids, xanthones, etc. The large consumption of herbal drugs, in spite of the efficiency of -

Abstract Plant small RNAs (sRNAs) are important regulatory elements that fine-tune gene expression and maintain genome integrity by silencing transposons. They have critical roles in most pathways involved in plant growth and reproductive development. Reproductive organs of monocots produce abundant phased, small interfering RNAs (phasiRNAs). The 21-nt reproductive phasiRNAs triggered by miR2118 are highly enriched in pre-meiotic anthers, and have not been described in eudicots. -

Recommendation of Native Species for the Reforestation of Degraded Land Using Live Staking in Antioquia and Caldas’ Departments (Colombia)
UNIVERSITÀ DEGLI STUDI DI PADOVA Department of Land, Environment Agriculture and Forestry Second Cycle Degree (MSc) in Forest Science Recommendation of native species for the reforestation of degraded land using live staking in Antioquia and Caldas’ Departments (Colombia) Supervisor Prof. Lorenzo Marini Co-supervisor Prof. Jaime Polanía Vorenberg Submitted by Alicia Pardo Moy Student N. 1218558 2019/2020 Summary Although Colombia is one of the countries with the greatest biodiversity in the world, it has many degraded areas due to agricultural and mining practices that have been carried out in recent decades. The high Andean forests are especially vulnerable to this type of soil erosion. The corporate purpose of ‘Reforestadora El Guásimo S.A.S.’ is to use wood from its plantations, but it also follows the parameters of the Forest Stewardship Council (FSC). For this reason, it carries out reforestation activities and programs and, very particularly, it is interested in carrying out ecological restoration processes in some critical sites. The study area is located between 2000 and 2750 masl and is considered a low Andean humid forest (bmh-MB). The average annual precipitation rate is 2057 mm and the average temperature is around 11 ºC. The soil has a sandy loam texture with low pH, which limits the amount of nutrients it can absorb. FAO (2014) suggests that around 10 genera are enough for a proper restoration. After a bibliographic revision, the genera chosen were Alchornea, Billia, Ficus, Inga, Meriania, Miconia, Ocotea, Protium, Prunus, Psidium, Symplocos, Tibouchina, and Weinmannia. Two inventories from 2013 and 2019, helped to determine different biodiversity indexes to check the survival of different species and to suggest the adequate characteristics of the individuals for a successful vegetative stakes reforestation. -
Biological Nitrogen Fixation in Tropical Dry Forests of Costa Rica: Patterns and Controls

Powers, Adviser June 2014 © Copyright by Maria Gabriela Gei, June 2014. All rights reserved. i Acknowledgements It would not have been possible to develop this thesis without the support of my mentors, colleagues, friends and family. Above all, I would like to thank my advisor Jennifer Powers for her constant support and encouragement. She was present and deeply involved at every single step along this way but she also allowed and motivated me to work independently. She encouraged me to seek funding from numerous sources and gave me immediate advice whenever I asked for it. Most importantly, she constantly reminded me of the exciting, fun and collaborative aspects of science. Her friendship and mentoring were essential to the success of this research! I would also like to acknowledge the members of my thesis committee: Sasha Reed, Sarah Hobbie, Rebecca Montgomery, and Deborah Allan. They provided insightful advice during the last six years that significantly improved my work. I am thankful that they were willing to accommodate my frequent travel to meet with me. They enriched my research experience significantly by helping me think about my ideas from numerous angles. I consider myself extremely lucky and honored by having had the example, mentorship and the opportunity to work with these five amazing scientists! I spent two years living and developing this research at the heart of Área de Conservación Guanacaste (ACG) in northwestern Costa Rica. -
Endemism in Recently Diverged Angiosperms Is Associated with Chromosome Set Duplication
Endemism in Recently Diverged Angiosperms Is Associated With Chromosome Set Duplication Sara Villa University of Milan: Universita degli Studi di Milano Matteo Montagna Universita degli Studi di Milano Simon Pierce ( [email protected] ) Università degli Studi di Milano: Universita degli Studi di Milano https://orcid.org/0000-0003-1182- 987X Research Article Keywords: adaptative radiation, apo-endemics, diversity creation, genome doubling, neo-endemism, speciation mechanism Posted Date: June 17th, 2021 DOI: https://doi.org/10.21203/rs.3.rs-550165/v1 License: This work is licensed under a Creative Commons Attribution 4.0 International License. Read Full License Page 1/22 Abstract Chromosome set duplication (polyploidy) drives instantaneous speciation and shifts in ecology for angiosperms, and is frequently observed in neo-endemic species. However, the extent to which chromosome set duplication is associated with endemism throughout the owering plants has not been determined. We hypothesised that across the angiosperms polyploidy is more frequent and more pronounced (higher evident ploidy levels) for recent endemics. Data on chromosome counts, molecular dating and distribution for 4210 species belonging to the major clades of angiosperms were mined from literature-based databases. As all clades include diploid taxa, with polyploids representing a possible ‘upper limit’ to the number of chromosomes over evolutionary time, upper boundary regression was used to investigate the relationship between the number of chromosomes and time since taxon divergence, both across clades and separately for families, with endemic and non-endemic species compared. A signicant negative exponential relationship between the number of chromosomes and taxon age was 2 evident across angiosperm clades (R adj=0.48 with endemics and non-endemics considered together, 2 2 R adj=0.46 for endemics; R adj=0.44 for non-endemics; p ≤0.0001 in all cases), which was three times stronger for endemics (decay constant=0.12, cf.
