Led by Ms Melissa Reynolds, the PTB platform, originally known as the "DNA Marker Platform" has made significant strides in DNA fingerprinting since its inception in 2008. This platform has successfully generated DNA marker profiles for 100,000 trees in South African trees breeding programmes, using microsatellite DNA markers and more advance SNP DNA marker arrays for pines and eucalypts. The team conducts comprehensive DNA fingerprinting, parentage and genomic relationship analyses.

Expanding its focus, the platform now also encompasses macadamia and wattle species, supported by a highly skilled technical team and cutting-edge high throughput DNA analysis equipment.
