| The distinction between Anetholea and Syzygium is lessened due to the occurrence of epigeal germination and dry fruitedness in the latter genus also and it is concluded that Anetholea is better placed within Syzygium. Analysis of sequence data from nuclear ribosomal DNA and the chloroplast genome support this conclusion. The sole species of Anetholea, A. anisata, is transferred to Syzygium and the new combination, S. anisatum (Vickery) Craven & Biffin, made. Syzygium wilsonii subsp. cryptophlebium is reinstated at species rank, necessitating the new combination, S. cryptophlebium (F. Muell.) Craven & Biffin. Two new taxa of Syzygium are described from Australia, S. wilsonii subsp. epigaeum Craven & Biffin and S. maraca Craven & Biffin. |

| Abstract Araucaria angustifolia is endemic to southern Brazil. Known as Brazilian pine, A. angustifolia is the only native conifer species with economic and social relevance in this country. Due to massive exploitation, it has suffered a significant population decline and currently is classified as critically endangered. This encouraged the scientific community to investigate genetic features in Brazilian pine to increase resources for management and preservation. In this work, RNA-Seq data was used to determine the complete nucleotide sequence of the A. angustifolia chloroplast genome (cpDNA). The cpDNA is 146,203 bp in length and contains 122 genes, including 80 protein-coding genes, 5 ribosomal RNA genes, and 37 tRNA genes. Coding regions comprise... |

| Abstract Myrteae is the largest and most diverse tribe within Myrtaceae and represents the majority of its diversity in the Neotropics. Members of Myrteae hold ecological importance in tropical biomes for the provision of food sources for many animal species. Thus, due to its several roles, a growing interest has been addressed to this group. In this study, we report the sequencing and de novo assembly of the complete chloroplast (cp) genomes of six Myrteae species: Eugenia brasiliensis, E. pyriformis, E. nitida, Myrcianthes pungens, Plinia edulis and Psidium cattleianum. We characterized genome structure, gene content, and identified SSRs to detect variation within Neotropical Myrteae. The six newly sequenced plastomes exhibit a typical quadripartite... |

| ABSTRACT The green algal genus Bryopsis has simple morphology and high phenotypic plasticity, making it difficult to identify its species based on morphological characteristics alone. This study evaluated the diversity of Bryopsis in northeastern Brazil (the State of Pernambuco), based on morphological and molecular data using the markers tufA and rbcL. Molecular analyses were incongruent with morphology, demonstrating the existence of cryptic and polymorphic species in the genus. Of the four taxa cited for the area based only on morphological data (Bryopsis corymbosa, B. pennata, B. plumosa, Bryopsis sp.), only B. pennata was recorded. Typical specimens of B. pennata and B. plumosa were grouped with low genetic divergence, 0-0.21 % for tufA and no... |
