Prof. Tang Chaorong at the Rubber Research Institute, the Chinese Academy of Tropical Agricultural Sciences (CATASRRI) in Danzhou, Hainan, China and his colleagues reported a more complete genome sequence of rubber tree (Hevea brasiliensis) based on the widely cultivated clone Reyan 7-33-97, which was published on 23 May 2016 in a famous journal Nature Plants with the article entitled “The rubber tree genome reveals new insights into rubber production and species adaptation ”. Sometime earlier a draft sequence of the rubber tree based on clone RRIM 600 was published by a Malaysian team. The genome of the rubber tree has revealed a group of genes that may drive the unique ability of the rubber tree to produce higher yield of natural rubber. Four members of the REF/SRPP gene family, which are thought to be involved in rubber synthesis were found among the most highly expressed genes in latex. The author also identified more than 500 genes that responded to ethylene, a plant hormone known to stimulate rubber production. These findings open a new perspective for resequencing of commercial clones and guiding of our research activities in breeding of much higher yielding clones of commercial importance. This is an important event in the research and development of natural rubber, and will surely lead to close collaboration among scientists of the world especially in natural rubber research.
