TI - Three polyphenol oxidases from hybrid poplar are differentially expressed during development and after wounding and elicitor treatment N2 - The expression of three polyphenol oxidase (PPO; EC 1.10.3.1)genes was investigated in hybrid poplar (Populus trichocarpa ยท P. deltoides). PtdPPO1 was previously isolated as a wound- and herbivore-inducible PPO (Constabel et al. Plant Physiol 124: 285-295, 2000), whereas PtdPPO2 and PtdPPO3 are two novel hybrid poplar PPO genes isolated from stem and root tissue, respectively. Sequence analysis revealed that the three PPOs were 60-66 UR - https://drive.google.com/file/d/1KNjuYyiGWZEbHP9GCZU9aBa_k62up0Z4/view?usp=drivesdk ER -
