Research Projects: Dr. Jean-Charles Leplé is involved in genomic studies on wood formation in poplar, and more specifically on tension wood, formed in response to a mechanical stress. In the past, he has participated to several collaborative projects focused on genetic engineering on poplar for insect tolerance and lignin metabolism modifications. He has more than 15 years of expertise in genetic transformation of poplar species. In 1992 he published an efficient transformation procedure for a poplar clone (INRA 717-1-B4) largely used all over the world (123 citations from Web of Science). He recently developed improvements to speed up the screening of transgenic wood zone on poplar. He has over 10 years of experience in the management of field trials of transgenic poplars. He has been co-supervisor of 3 PhD thesis and 10 Master degrees. More than 40 publications in SCI-indexed journals.
