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 ...

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.

Changes in cell wall composition and ultrastructure related to desiccation during the seed maturation of Paubrasilia echinata (brazilwood)

Protoplasma, 2022
Paubrasilia echinata (brazilwood) is an endangered native tree from the Brazilian Atlantic Forest whose seeds tolerate maturation drying, but, unlike classic orthodox seeds, they quickly lose viability after shedding. This work analyzed the biochemical and ultrastructural changes during the maturation of brazilwood seeds, with particular attention to ...

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.

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.

Intraspecific variation of Paubrasilia echinata (Fabaceae) wood along a latitudinal gradient in Brazil

Flora, 2019
Abstract Molecular and taxonomy approach have been made to understand the differences among the three morphotypes of Paubrasilia echinata, termed laranja, cafe and arruda. However, there is no wood anatomic study considering these morphotypes and their probable anatomical similarity.

Climate signals in tree rings of Paubrasilia echinata (Leguminosae-Caesalpinioidea) from the Atlantic Forest of Brazil

Trees, 2019
Tree-ring chronologies were built for wild and cultivated Paubrasilia echinata, a presently endangered species. Significantly P. echinata showed measurably different growth patterns related to the environment where wild and cultivated trees have grown. Paubrasilia echinata once grew so abundantly along the tropical coast of South America that the names

Salicylic Acid Modulates Morphophysiological Responses of Paubrasilia echinata Seedlings Irrigated with Saline Water

International Journal of Plant Biology
Rising salt concentration in water induces osmotic stress and ionic toxicity, compromising photosynthesis, growth, and survival of threatened species such as Paubrasilia echinata and highlighting the need for stress-mitigating compounds such as salicylic acid.

A proof-of-concept study: Determining the geographical origin of Brazilwood, (Paubrasilia echinata) with the use of strontium isotopic fingerprinting

Science & Justice
The illicit exploitation of Brazilwood (Paubrasilia echinata) presents a significant challenge in Brazil, given its substantial value in the global production of bows for musical instruments. To address timber provenance, the use of strontium (Sr) isotope ratios as indicators of bedrock signatures has emerged as a robust tool in forensic investigations.
