Rubber is a strategic raw material for manufacturing of about fifty thousand products, including more than 400 medical devices. Natural rubber characteristics can't be matched by artificial polymers, and some products needs natural rubber in their composition, like medical procedures gloves and airplanes and trucks high-resistance tires. About 2,500 plant species produce latex, where rubbertree (Heveavbrasiliensis (Willd.) Muell. Arg.) is considered natural rubber main source. South American Leaf Blight (SALF), a disease caused by fungi Microcyclos ulei, is currently limiting rubber production in Latin America, also represeting a threat to asian and african H. brasiliensis fields. H. benthamiana and H. pauciflora are considered of extreme importance for H. brasiliensis breeding programs, due to these species natural resistance to M. ulei infection. Until now, no transcriptome study was made focusing on H. benthamiana or H. pauciflora, resulting on few available data on public databases as GenBank. Next-gen sequencing and assembly of H. benthamiana and H. pauciflora transcriptomes, and their subsequent correlation to H. brasiliensis genes throught orthologs groups definition can be a viable strategy for knowledge consolidation on Hevea genus. Moreover, transcriptome study of these two species will supply breeding programs with important genomic resources as microsatellite and single nucleotide polymorphisms molecular markers, allowing their direct employment on H. brasiliensis molecular breeding.
