1. METABOLÔMICA DE PLANTAS: MÉTODOS E DESAFIOS
Metabolomics has played a central role in various areas of plant sciences, offering new perspectives for the advancement of agriculture, drug discovery, chemical ecology and taxonomy. Plant metabolomics (identification and quantification) aims to understand the relationship between biological systems and genetic, pathological and or environmental stimuli in

2. Taxonomic relevance of leaf anatomy in Banisteriopsis C.B. Rob. (Malpighiaceae)
ABSTRACT We describe the leaf anatomy of 42 of the 60 species of the genus Banisteriopsis, one of the largest and most diverse genera of Malpighiaceae in the Cerrado domain. Our aim was to identify anatomical leaf characters useful for the taxonomy and systematics of this morphological diverse genus. Expanded leaves from herbarium specimens were rehydrated a

3. Relationships between Bloom’s taxonomy, judges’ estimation of item difficulty and psychometric properties of items from a progress test: a prospective observational study
ABSTRACT BACKGROUND: Progress tests are longitudinal assessments of students’ knowledge based on successive tests. Calibration of the test difficulty is challenging, especially because of the tendency of item-writers to overestimate students’ performance. The relationships between the levels of Bloom’s taxonomy, the ability of test judges to predict

6. New insights into the detection and molecular characterization of Cryptosporidium with emphasis in Brazilian studies: a review
ABSTRACT Cryptosporidium spp. is a pathogenic protozoan present in the gastrointestinal tract of several hosts. This protozoan was originally classified as within the Coccidia Class and has recently been reclassified to gregarine based on studies that observed the evolutionary phases from the process of excision and sequencing of the 18S rRNA gene. Molecular

7. Strawberry breeding in Brazil: current momentum and perspectives
RESUMO O Brasil depende quase que na totalidade de cultivares de morangueiro importadas, o que resulta em custos mais altos para os produtores e menor adaptação dos genótipos às condições brasileiras de cultivo. Para reverter este cenário, é necessário maior enfoque ao melhoramento do morangueiro no Brasil; caso contrário, o país continuará depen

8. Investigating the Spectra constellations of the Hierarchical Taxonomy of Psychopathology (HiTOP) model for personality disorders based on empirical data from a community sample
Objective: The Hierarchical Taxonomy of Psychopathology (HiTOP) posits that psychopathology is hierarchically structured. For personality disorder (PD) traits, there are five spectra: internalizing, thought disorder, disinhibited externalizing, antagonistic externalizing, and detachment. Empirical findings suggest a sixth group, compulsivity. In this resear

10. Next-generation sequencing analysis reveals high bacterial diversity in wild venomous and non-venomous snakes from India
Abstract Background: The oral cavities of snakes are replete with various types of bacterial flora. Culture-dependent studies suggest that some of the bacterial species are responsible for secondary bacterial infection associated with snakebite. A complete profile of the ophidian oral bacterial community has been unreported until now. Therefore, in the pres

11. Trypanosoma janseni n. sp. (Trypanosomatida: Trypanosomatidae) isolated from Didelphis aurita (Mammalia: Didelphidae) in the Atlantic Rainforest of Rio de Janeiro, Brazil: integrative taxonomy and phylogeography within the Trypanosoma cruzi clade
BACKGROUND Didelphis spp. are a South American marsupial species that are among the most ancient hosts for the Trypanosoma spp. OBJECTIVES We characterise a new species (Trypanosoma janseni n. sp.) isolated from the spleen and liver tissues of Didelphis aurita in the Atlantic Rainforest of Rio de Janeiro, Brazil. METHODS The parasites were isolated and a

12. Morphoanatomy of nectaries of Chamaecrista (L.) Moench sections Chamaecrista , Caliciopsis and Xerocalyx (Leguminosae: Caesalpinioideae)
ABSTRACT Nectaries are specialized structures that secrete nectar. Several species of Chamaecrista possess nectaries on the petiole, which have been shown to vary widely in morphology and the chemical nature of their secretion. However, a comprehensive investigation of the nectaries of the clade formed by sect. Chamaecrista, Caliciopsis and Xerocalyx has yet
