1. Comparative genome analysis of the SPL gene family reveals novel evolutionary features in maize
Abstract SPLs are plant-specific transcription factors that play important regulatory roles in plant growth and development. Systematic analysis of the SPL family has been performed in numerous plants, such as Arabidopsis, rice, and Populus. However, no comparative analysis has been performed across different species to examine evolutionary features. In this

2. Comparative morphology of the stomach ossicles of four freshwater crabs species of Dilocarcinini (Crustacea, Decapoda, Trichodactylidae)
Abstract The morphology of the foregut ossicles of representatives of four genera of Dilocarcinini were described to assess the usefulness of the ossicles as possible morphological characters in studies on the intrafamilial relationships of Trichodactylidae. Stomachs of specimens of Dilocarcinus pagei Stimpson, 1861, D. septemdentatus (Herbst, 1783), Moreiro

3. The complete mitochondrial genome of Engyodontium album and comparative analyses with Ascomycota mitogenomes
Abstract Engyodontium album is a widespread pathogen that causes different kinds of dermatoses and respiratory tract diseases in humans and animals. In spite of its perniciousness, the basic genetic and molecular background of this species remains poorly understood. In this study, the mitochondrial genome sequence of E. album was determined using a high-thro

4. Molecular analyses reveal the occurrence of three new sympatric lineages of velvet worms (Onychophora: Peripatidae) in the eastern Amazon basin
Abstract In the present study, we investigated the possible existence of new lineages of peripatids through comparisons between known Neotropical species and specimens obtained from two locations in Pará, a state in eastern Brazilian Amazonia using a molecular approach based on sequences of the mtDNA genes COI, 16Sr RNA, and 18S RNA. The analyses included a

5. A nuclear ribosomal DNA pseudogene in triatomines opens a new research field of fundamental and applied implications in Chagas disease
A pseudogene, designated as "ps(5.8S+ITS-2)", paralogous to the 5.8S gene and internal transcribed spacer (ITS)-2 of the nuclear ribosomal DNA (rDNA), has been recently found in many triatomine species distributed throughout North America, Central America and northern South America. Among characteristics used as criteria for pseudogene verification, secondar

6. Seed coat diversity in some tribes of Cucurbitaceae: implications for taxonomy and species identification
To evaluate their diagnostic value in systematic studies, seed coat morphology for 16 taxa from 11 genera of Cucurbitaceae were examined using stereomicroscopy and scanning electron microscopy. The taxa included representatives of the tribes Benincaseae, Bryonieae, Coniandreae, and Luffeae in order to evaluate their diagnostic value in systematic studies. Ma

7. Sistemática e filogenética molecular do gênero Hexachlamys (Myrtaceae) através do uso de marcadores plastidiais e nucleares
Myrtaceae family includes more than 5500 species of trees and shrubs, mainly distributed in tropical and subtropical areas of the world. Species of this family have great ecological significance in forest ecosystems, and they are also economically important to the pharmaceutical, food, cosmetic and perfumery industries. The systematic of this family is very

8. Phylogenetic analysis and systematic revision of the genus Anchylohynchus Schoenherr, 1836 (Curculionidae: Derelomini), using discrete and continuous morphological characters / Análise filogenética e revisão sistemática do gênero Anchylorhynchus Schoenherr, 1836 (Curculionidae: Derelomini), com o uso de caracteres morfológicos contínuos e discretos
Recently, phylogenetic analysis based on continuous characters was made accessible. This increases the pool of characters available for morphology-based phylogenetic analyses, but there is still no consensus on how this kind of characters should be coded and analyzed. In the present study, I assessed the use of continuous characters in phylogenies from two d

9. Estudos cromossômicos e moleculares em espécies de lagartos microteídeos, com ênfase na tribo Ecpleopodini (Gymnophthalmidae, Squamata) / Chromossomal and molecular studies on species of microteiid lizards, with emphasis on Ecpleopodini (Gymnophthalmidae, Squamata)
This study contributes to knowledge of the family Gymnophthalmidae, adding new genetic data of three genes for the tribe Ecpleopodini and description of 11 new karyotype for the family, belonging to the tribes Ecpleopodini, Heterodactylini, Iphisiini and Gymnophthalmini. Phylogenetic analysis for the tribe Gymnophthalmini aimed to investigate the position of

10. Estudos moleculares em Gymnotus pantherinus (Gymnotiformes, Gymnotidae): uma abordagem sistemática e filogeográfica / Molecular studies in Gymnotus pantherinus (Gymnotiformes: Gymnotidae): a systematic and phylogeographic approach
Gymnotus pantherinus is an endemic fish species found in the Brazilian coastal drainages occurring from Bahia to Rio Grande do Sul states. Morphological evidence has suggested that Gymnotus pantherinus might constitute a species complex. In the present study, the taxonomic status of Gymnotus species group has been evaluated using both mitochondrial and nucle

11. Estudos filogenéticos e sistemáticos em Rutaceae: análise cladística e posicionamento de Almeidea A. St.-Hil. entre as Galipeinae (Galipeae, Rutoideae) com o uso de dados morfológicos e moleculares / Phylogenetic and systematic studies in Rutaceae: cladistic analysis and position of Almeidea A.St.-Hil. within Galipeinae (Galipeae, Rutoideae) inferred from morphological and molecular data
In the present study the monophyly and phylogenetic relationships of Almeidea A. St.-Hil. (Galipeinae, Rutaceae) were examined using morphological data, including macromorphology of leaves and flowers and pollen morphology and molecular data, including sequences from nuclear regions ITS-1 and ITS-2 and the plastid regions trnL-trnF and rps-16. Almeidea is a

12. Relações filogenéticas da superfamília Doradoidea (Ostariophysi, Siluriformes) / Phylogenetic relationships of the superfamily Doradoidea (Ostariophysi, Siluriformes)
The superfamily Doradoidea (Siluriformes) is composed of two Neotropicalendemic families: Doradidae and Auchenipteridae. The sister-group relationship between these families has been corroborated by previous studies of both morphological and molecular data. Previous studies have also provided support for evolutionary relationships between doradoid genera and
