Gene insertion into Hevea brasiliensis
Plant Cell Reports, 1994A transformation system has been developed for Hevea brasiliensis using the particle gun method. Anther derived calluses were transformed with vectors harbouring the ß-glucuronidase (gus) gene, the neomycin phosphotransferase (nptII) gene, and the chloramphenicol acetyl transferase (cat) gene.

Genomic technologies for Hevea breeding
2019The commercial production of high quality natural rubber (NR) solely depends on Hevea brasiliensis Muell. Arg, (Para rubber tree) and accounts for >98% of total production worldwide. NR with its unique properties is an essential commodity for the automobile industry and its synthetic counterparts are in no way substitute to it.

Hevea : micropropagation by somatic embryogenesis
1997The different steps of the process for maintained somatic embryogenesis were described. The current yields of the process were shown. They led to discuss on the limiting factors with the prospect of mass micropropagation. The first field trial with five, years old vitroplants was analysed. First conclusions were promising.

Chain Scission in the Oxidation of Hevea. II
Journal of the American Chemical Society, 1955Abstract Oxidation of natural rubber in latex yields two molecules of carbon dioxide, one of formic acid and one of acetic acid for each rupture of the hydrocarbon chain. The yields of these products can be interpreted readily by reference to the structure of the primary oxidation products of 1,5-diolefins established by Bolland and Hughes.

Mycologia, 1945
In December, 1943, an unknown disease characterized by a severe leaf spotting was found in a nursery of Hevea Spruceana at Turrialba, Costa Rica. Six weeks later, following a prolonged rainy period, this disease had reached epiphytotic proportions in the spruceana nursery where it was causing leaf, petiole, and twig blight, and also was producing minor

The Breeding of Hevea Brasiliensis
Rubber Chemistry and Technology, 1961Abstract The intrinsic yield of Hevea brasiliensis has been more than tripled over the past thirty-five years largely by the efforts of plant breeders. While it is not to be expected that progress will be as rapid over the next thirty-five years, yet the end is not in sight, and indeed new horizons are opening up.

Hevea brasiliensis is the most recent domesticated tree species from Amazonian rain forest producing latex of commercial utility. Major hurdles for genetic improvement of rubber tree were attributed to its perennial nature, long juvenile period, and a narrow genetic base.

The Instability of Hevea Latex
Rubber Chemistry and Technology, 1941Abstract In a study made on plantations in Malaya, it was found that the cause of instability is not the same for both fresh and preserved latex. The autocoagulation of fresh latex, as it will be shown, is not caused by the acid formed by bacterial action on the serum components (autoacidification).
