secondary xylem development stage cell differentiation stage of secondary xylem PO:0025469 二次木部の細胞分化期 (Japanese, exact) A secondary xylem development stage (PO:0025427) that occurs during the interval between the end of a cell division stage of secondary xylem (PO:0025463) and the death of the last living cell in the secondary xylem. During a this stage, cells of secondary xylem undergo cell differentiation (GO:0030154), including cell growth (GO:0016049), cell morphogenisis (GO:0000902), or cell death (GO:0008219). Cell death is considered part of differentiation in secondary xylem, because it is an essential part of wood development. This stage succeeds the last cell division in a cell division stage of secondary xylem, even though cell differentiation may begin before all cell division finishes. etapa de diferenciaci&#243 celular del xilema secundario (Spanish, exact) plant_structure_development_stage 2012-03-14T02:14:09Z PO_GIT:447 rwalls
