AB  - Regulation of gene expression, as determined by the genetics of the tree species, 
      is a major factor in determining wood quality. Therefore, the identification of 
      genes that play a role in xylogenesis is extremely important for understanding 
      the mechanisms shaping the plant phenotype. Efforts to develop new varieties 
      characterized by higher yield and better wood quality will greatly benefit from 
      recognizing and understanding the complex transcriptional network underlying wood 
      development. The present study provides a detailed comparative description of the 
      changes that occur in genes transcription and the biosynthesis of 
      cell-wall-related compounds during xylogenesis in Populus trichocarpa pioneer 
      roots and stems. Even though results of microarray analysis indicated that only 
      approximately 10% of the differentially expressed genes were common to both 
      organs, many fundamental mechanisms were similar; e.g. the pattern of expression 
      of genes involved in the biosynthesis of cell wall proteins, polysaccharides, and 
      lignins. Gas chromatography time-of-flight mass spectrometry (GC-TOF-MS) shows 
      that the composition of monosaccharides was also very similar, with an increasing 
      amount of xylose building secondary cell wall hemicellulose and pectins, 
      especially in the stems. While hemicellulose degradation was typical for stems, 
      possibly due to the intensive level of cell wall lignification. Notably, the main 
      component of lignins in roots were guiacyl units, while syringyl units were 
      dominant in stems, where fibers are especially needed for support. Our study is 
      the first comprehensive analysis, at the structural and molecular level, of 
      xylogenesis in under- and aboveground tree parts, and clearly reveals the great 
      complexity of molecular mechanisms underlying cell wall formation and 
      modification during xylogenesis in different plant organs.
