First insight into micro-genomics of cambial activity per cell type in poplar
Résumé
As a model tree, poplar is increasingly studied at the genomic level. Going deeper into the understanding of relationships between cambial activity and wood formation, we have developed in collaboration between INRA and UPSC a method to analyze gene expression at the cellular level in the poplar cambium. After general considerations explaining why and how to perform microsampling at the cell level, we will develop some results obtained during the PhD work of Nadia Goué showing main gene families expressed in the fusiform and radial cells microdissected tram the poplar cambium. These results will be also analyzed in line with the poplar genome sequence obtained recently.
