Hevea brasiliensis, the rubber tree, is the most economically important member of the genus Hevea because its sap-like extract, latex, can be collected and is the primary source of natural rubber. The rubber tree initially grew only in the Amazon Rainforest but increasing demand and the discovery of the vulcanization procedure in 1839 led to the rubber boom in that region, enriching the cities of Belém and Manaus.
Now researchers from Mahidol University, Thailand have used RNA-Seq to sequence the transcriptome from the vegetative shoot apex of the rubber tree. Clustering and assembly of the reads produced a total of 113 313 unique sequences, comprising 28 387 isotigs and 84 926 singletons. Also, 17 819 expressed sequence tag (EST)-simple sequence repeats (SSRs) were identified from the data set.
