Transcription profiling of fusiform cambial and ray cambial cells from poplar trees

ABSTRACT: (paper abstract) Wood is a renewable resource that serves as a sustainable raw material for energy, fuels and materials. A basic understanding of the cambial meristem and the origin of wood cells is critical for forest tree molecular breeding to increase the availability of woody raw materials. Gene expression per cell type in the cambium of poplar (Populus trichocarpa x P. deltoïdes cultivar Boelare) was investigated using poplar microarray. Cells were hand microdissected from lyophilized sections of vascular cambial zone sampled in growing poplar. Two cell types were isolated, fusiform cambial cells (FCCs) and ray cambial cells (RCCs). Results showed about one thousand genes differentially expressed per cell type. Microarray expression results were validated by a second cell sampling use
