Future uncertainties for the distribution and conservation of Paubrasilia echinata under climate change [PDF]

Acta Botanica Brasilica, 2019
ABSTRACT Paubrasilia echinata is a widely cultivated endangered tree species with small populations restricted to a narrow strip of habitats along the Brazilian coast. The potential impacts of climate change on the distribution of P. echinata have yet to be investigated, and so it remains unknown whether protected areas will ensure the persistence of ...

IN SILICO STUDIES OF DITERPENES EXTRACTED FROM Paubrasilia echinata Lam. AND DERIVATIVES AGAINST HIV-1 INTEGRASE AND REVERSE TRANSCRIPTASE [PDF]

Periodico Tche Quimica, 2022
Introduction: HIV, whose viral multiplication is associated with three enzymes. Reverse transcriptase is responsible for synthesizing vital DNA based on its RNA; integrase is responsible for integrating viral DNA into human DNA; and protease is responsible for cleaving the genetic code into smaller, functional units.

A Biodiversity Hotspot Losing Its Biocultural Heritage: The Challenge to Biocultural Conservation of Brazilwood (Paubrasilia echinata)

Frontiers in Forests and Global Change, 2022
The biocultural heritage of a region is developed and adapted after centuries of interrelationships between humans and nature. The endangered brazilwood [Paubrasilia echinata (Lam.), E. Gagnon, H.C. Lima, and G.P. Lewis] is a flagship species with cultural and economic importance that is directly affected by the history of human occupation on the ...

Photosynthesis of plants of shade-tolerant ecotype of Paubrasilia echinata are more tolerance to drought than the sun-tolerant ecotype

Plant Stress, 2023
Frequent and prolonged droughts are predicted for the Northeast region of Brazil until the end of this century. How the sun-tolerant and shade-tolerant tree species of the tropical forests in this region of the planet will respond to this climate scenario is a matter of global interest.

Water Deficit Modulates Morphophysiological and Enzymatic Changes in Paubrasilia echinata Seedlings

Ecologies
Water scarcity, intensified by climate change, limits the growth and survival of threatened tree species, such as Paubrasilia echinata (Lam.) Gagnon, H.C.Lima & G.P.Lewis. This study analyzed the effects of water availability in the soil on the morphophysiology and enzymatic activity of P.

Light spectrum and explant type drive hormonal and proteomic reprogramming in micropropagation of the endangered Paubrasilia echinata

Plant Cell, Tissue and Organ Culture
Abstract Paubrasilia echinata , the national tree of Brazil, is critically endangered due to centuries of overexploitation for its high-quality wood and dye-producing sap. Consequently, the development of efficient propagation systems is urgent for its conservation and restoration.
