dracaena draco/atrophy

BACKGROUND Infertility is a common complication in diabetic men and experimental animals, mainly due to loss of germ cells by apoptotic cell death. The aim of this study was to evaluate the effects of aqueous and ethanol extracts of Dracaena arborea in streptozotocin-induced ultra-structural

Phenylalanine ammonia-lyase (PAL) is the key enzyme of the phenylpropanoid pathway, playing an important role in plant development and defence. We cloned a partial cDNA of PAL gene, DcPAL1, from Dracaena cambodiana seedlings using RT-PCR with degenerate primers that were designed based on a multiple
