Abstract: As the uppermost carbon pool and important renewable source, wood has dual functions in both responding to the global climate change and meeting the resource demands of human society, thereby it is essential to understand the molecular mechanism of wood formation. In this study, a 1DE-based nanoLC-MS/MS method was introduced to analyze the proteome in the secondary vascular system of Populus tomentosa, and the identified proteins included:14 proteins associated cell division; 7 proteins related to transcription factors; 22 proteins associated with cytoskeleton; 31 proteins associated with signal transduction;and 14 proteins associated with cell wall formation. The corresponding genes of these proteins participate in regulating cambial activity. The accomplishment of this proteome analysis laid a foundation for further understanding the molecular mechanism of wood formation.

Key words: LC-MS/MS, proteome profile, secondary vascular system, Populus tomentosa
