Draft genome sequence of the rubber tree Hevea brasiliensis
“Hevea brasiliensis, a member of the Euphorbiaceae family, is the major commercial source of natural rubber (NR). NR is a latex polymer with high elasticity, flexibility, and resilience that has played a critical role in the world economy since 1876.
Here, we report the draft genome sequence of H. brasiliensis. The assembly spans ~1.1 Gb of the estimated 2.15 Gb haploid genome. Overall, ~78% of the genome was identified as repetitive DNA. Gene prediction shows 68,955 gene models, of which 12.7% are unique to Hevea. Most of the key genes associated with rubber biosynthesis, rubberwood formation, disease resistance, and allergenicity have been identified.
The knowledge gained from this genome sequence will aid in the future development of high-yielding clones to keep up with the ever increasing need for natural rubber.”

Colour chart used by Austrian botanical illustrator Ferdinand Bauer (1760-1826) for his field observations. His technique was to sketch a ‘painting-by-numbers’ in situ, which we he could later add colour to after returning from whichever botanical expedition he was on. The example of his painting shown here is a depiction of Grevillea banksii, named for the great Sir Joseph.
