Gia Lai has great potential for developing agricultural production, and it is home to a large crop industrial material area in Vietnam. It boasts nearly 100,000 hectares of coffee and nearly 90,000 hectares of rubber. The area has immense potential to develop its agricultural production due to its unique characteristics of soil and climate, which can support a rich diversity of plants and animal with high economic value.

Natural rubber is an economically important material. Currently the Pará rubber tree, Hevea brasiliensis is the main commercial source. Little is known about rubber biosynthesis at the molecular level. Next-generation sequencing (NGS) technologies brought draft genomes of three rubber cultivars and a variety of RNA sequencing (RNA-seq) data. However, no current genome or transcriptome databases (DB) are organized by gene.

Natural rubber, an indispensable commodity used in approximately 40,000 products, is fundamental to the tire industry. The rubber tree species Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell-Arg., which is native the Amazon rainforest, is the major producer of latex worldwide.

Somatic embryogenesis (SE) is a promising technology for plant vegetative propagation, which has an important role in tree breeding. Though rubber tree (Hevea brasiliensis Muell. Arg.) SE has been founded, few late SE-related genes have been identified and the molecular regulation mechanisms of late SE are still not well understood.

Anthracnose leaf disease in rubber trees, caused by the attack of Colletotrichum gloeosporioides, have led to the serious decline in natural rubber production. Continuous usage of synthetic fungicide leave the toxic residues that harm the surrounding animals and plants and are not environmentally friendly. It needs a better solution with organic products that are safer, more effective and biodegradable. Piper species could be considered as a source of new natural products with potential antifungal activities.

Specific gravity (SG) of wood is a measure of the amount of structural material a tree species allocates to support and strength. Specific Gravity of wooden sample is taken by using the ratio of oven-dried weight of the sample to its volume at 12% moisture content. Rubber wood is a moderately heavy wood which can be used efficiently as a boat building material if proper preservative procedure can be carried out. Due to its refractory behaviour it can easily take up preservative solutions.

Rubber tree (Hevea brasiliensis Muell. Arg.) is the primarily commercial source of natural rubber in the world. Latex regeneration and duration of latex flow after tapping are the two factors that determine rubber yield of rubber tree, and exhibit a huge variation between rubber tree clones CATAS8-79 and PR107.

Sucrose (Suc), as the precursor molecule for rubber biosynthesis in Hevea brasiliensis, is transported via phloem-mediated long-distance transport from leaves to laticifers in trunk bark, where latex (cytoplasm of laticifers) is tapped for rubber.

Corynespora leaf fall (CLF) disease of rubber incited by Corynespora cassiicola is listed as a fourth most serious leaf disease of rubber in South East Asia. As the rubber is a tree crop it grows up to 60 – 70 feet height, management of this disease is not easy and it involves more price tag. The use of effective and economical management strategies is plays a vital role in efficient disease management in rubber plantations. To develop a tool to integrated disease management approach, tested different bio-agents, plant extracts and fungicides against Corynespora cassiicola.

Hevamine is a chitinase from the rubber tree Hevea brasiliensis. Its active site contains Asp125, Glu127, and Tyr183, which interact with the )1 sugar residue of the substrate. To investigate their role in catalysis, we have successfully expressed wild-type enzyme and mutants of these residues as inclusion bodies in Escherichia coli. After refolding and purification they were characterized by both structural and enzyme kinetic studies. Mutation of Tyr183 to phenylalanine produced an enzyme with a lower kcat and a slightly higher Km than the wild-type enzyme.

In Africa after independence, many countries attempted to ‘modernize’ their agricultural sectors through large-scale farming, providing subsidized credit, machinery, and land. These efforts almost universally failed (Eicher and Baker 1992). One of the largest and most well-documented cases was mechanized large scale sorghum and sesame production in Sudan that originated in attempts by financiers from the Gulf following the 1970s oil price spike, to transform the country into a regional breadbasket.

The description of historical events of rubber trees is mostly based on Polhamus 1962. Historically, rubber is a non-wood forest product that has been utilized since ancient times. Its geographic distribution has been present in all continents within the tropical forest areas. Many tree species were utilized until the starting of large scale rubber plantations in the early 1900s. It has been found that rubber was an important commodity in the ancient cultures of Latin America where people used it to have protective clothes, balls for playing games and syringes.

Until the early 1990’s latex production has been the main objective for rubberwood cultivation in Thailand. In 1989 the Thai government established a national natural forests logging ban. This law raised an immediate demand for construction and furniture wood in Thailand. Previously, the rubberwood trunks left over after the latex production, were either used as firewood at the plantation site or in charcoal production. Rubberwood offers qualities to ease off the demand for natural tropical forest trees and this way helps to decrease the pressure on illegal logging.
