Genetic diversity of cultivated accessions and wild species of rubber tree using EST‑SSR markers

open access: yesPesquisa Agropecuária Brasileira, 2012
The objective of this work was to evaluate the efficiency of EST‑SSR markers in the assessment of the genetic diversity of rubber tree genotypes (Hevea brasiliensis) and to verify the transferability of these markers for wild species of Hevea. Forty‑five

The phosphatides of Hevea Brasiliensis [PDF]

open access: yesBiochemical Journal, 1942
Abstract The presence of phosphatide in Hevea latex had long been suspected, but it was not until 1931 that Rhodes and Bishop isolated phosphatidic material containing 0.59 per cent nitrogen and 1.72 per cent phosphorus from the serum of latex which had been coagulated with ethanol.

Nutrient content and redistribution in leaves of Hevea brasiliensis and Pinus oocarpa /
Concentração e redistribuição de nutrientes em folhas de Hevea brasiliensis e Pinus oocarpa

open access: yesSemina: Ciências Agrárias, 2000
The content of macronutrients (N, P, K, Ca, Mg, and S) and nutrient redistribution were evaluated in leaves of two species, an 8 years old angiosperm (Hevea brasiliensis) and a 25 years old a gymnosperm (Pinus oocarpa), both cultivated on an eutrophic ...

Spatio-temporal development of cuticular ridges on leaf surfaces of Hevea brasiliensis alters insect attachment [PDF]

open access: yesRoyal Society Open Science, 2020
Cuticular ridges on plant surfaces can control insect adhesion and wetting behaviour and might also offer stability to underlying cells during growth. The growth of the plant cuticle and its underlying cells possibly results in changes in the morphology ...

Production of mutants affected in hormone signalling to dissect defence mechanisms in Hevea brasiliensis: the case of ethylene [PDF]

open access: yes, 2012
Production of mutants by genetic transformation is one alternative to dissect the response to hormonal treatment. Ethylene is an important plant hormone involved in latex production.

Sequence and expression analyses of ethylene response factors highly expressed in latex cells from Hevea brasiliensis.

open access: yesPLoS ONE, 2014
The AP2/ERF superfamily encodes transcription factors that play a key role in plant development and responses to abiotic and biotic stress. In Hevea brasiliensis, ERF genes have been identified by RNA sequencing. This study set out to validate the number
