Parasitic plant, from inside out: endophytic development in Lathrophytum peckoltii (Balanophoraceae) in host liana roots from tribe Paullineae (Sapindaceae).

Background And Aims: Balanophoraceae is one of the most bizarre and biologically interesting plant clades. It groups species with peculiar features that offers an opportunity for investigating several aspects of parasite plant development and morphogenesis. We analysed the development and the mature vegetative body of Lathrophytum peckoltii Eichler, focusing on the formation of the host-parasite interface.

Sugarloaf Land in south-eastern Brazil: a tropical hotspot of lowland inselberg plant diversity.

Background: Isolated monoliths of granitic and/or gneissic rock rising abruptly from the surrounding landscape are known as inselbergs. Dome-shaped inselbergs are common throughout the Atlantic Forest in south-eastern Brazil, a region known as Sugarloaf Land (SLL). This study aimed to create the first checklist of vascular plant species occurring on lowland inselbergs in SLL, with a focus on vegetation islands.

Fruits of the Brazilian Atlantic Forest: allying biodiversity conservation and food security.

Supplying food to growing human populations without depleting natural resources is a challenge for modern human societies. Considering this, the present study has addressed the use of native arboreal species as sources of food for rural populations in the Brazilian Atlantic Forest. The aim was to reveal species composition of edible plants, as well as to evaluate the practices used to manage and conserve them.

The natural impact of banana inflorescences (Musa acuminata) on human nutrition.

Banana inflorescences are popularly known as 'navels,' and they are used in Brazil as nutritional complements. However, the nutritional value of banana inflorescences (male flowers and bracts) has never been studied. Therefore, plant material of Musa acuminata, cultivar "ouro", was collected in Rio de Janeiro state, Brazil, and then submitted to chemical procedures to determine its nutritional composition.

Phytochemical screening, antibacterial activity and in vitro interactions between Costus cf. arabicus L. with UV-A and aminoglycosides.

In this study, the methanol extracts of of Costus cf. arabicus L. were evaluated for antibacterial activity against multiresistant strains of Escherichia coli and Staphylococcus aureus.

In vitro antibacterial, phototoxic, and synergistic activity of ethanol extracts from Costus cf. arabicus L.

In this study, ethanol extracts of stems and leaves of Costus cf. arabicus L. were evaluated for antibacterial activity against multidrug-resistant strains of Escherichia coli and Staphylococcus aureus.
