New insights into the novel and functional promoter sequences of β-1,3-glucanase gene from Hevea brasiliensis

open access: yesJournal of Plant Protection Research, 2021
β-1,3-glucanases play a major role in combating the abnormal leaf fall disease (ALF) caused by the oomycete Phytophthora spp. in Hevea brasiliensis, the major commercial source of natural rubber. In this study, partial sequences of four novel promoters

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.

Comparative transcriptome analysis of high- and low-embryogenic Hevea brasiliensis genotypes reveals involvement of phytohormones in somatic embryogenesis

open access: yesBMC Plant Biology, 2023
Background Rubber plant (Hevea brasiliensis) is one of the major sources of latex. Somatic embryogenesis (SE) is a promising alterative to its propagation by grafting and seed.

Characterization of Sugar Contents and Sucrose Metabolizing Enzymes in Developing Leaves of Hevea brasiliensis

open access: yesFrontiers in Plant Science, 2018
Sucrose-metabolizing enzymes in plant leaves have hitherto been investigated mainly in temperate plants, and rarely conducted in tandem with gene expression and sugar analysis. Here, we investigated the sugar content, gene expression, and the activity of

Seasonal and diurnal changes of two leaf pathogens of Rubber (Hevea brasiliensis Muell. Arg.) in the air of Iyanomo, Nigeria

open access: yesActa Mycologica, 2014
Air spore concentrations of Drechslera hevea Petch and Colletotrichum gloesporoides Penz were studied in a rubber nursery, over a 12-months period, from March 1976 to February 1977, using both the exposed nutrient medium technique and Rotorod samplers ...

Expression of the HEV2.1 gene promoter in transgenic Hevea brasiliensis

open access: yes, 2008
Hevein is involved in the coagulation of rubber particles and is known to be highly expressed in latex cells from Hevea brasiliensis. As all HEVEIN genes are highly conserved in their transcribed region, a promoter functional analysis was carried out in ...
