An assessment of genetic variation in vulnerable Borneo Ironwood Eusideroxylon zwageri Teijsm. & Binn. in Sarawak using SSR markers

Borneo Ironwood Eusideroxylon zwageri Teijsm. & Binn. has high market value for its valuable and durable tmber, which has put it at risk due to illegal logging. This study analyzed E. zwageri genetic variation using four microsatellite markers in populations at Nirwana Rehabilitation Forest (NRF...
