摘　　要：木质部细胞的分化过程包括了密切不可分的细胞程序死亡和次生壁构建两个过程。现在的研究主要是将两个过程分开来研究 ,各自在细胞生物学和分子生物学上取得了不少进展 ,有关次生细胞壁方面的研究时间长 ,成果也较大。有关木质部细胞脱分化的研究相对较少 ,但也已取得了可喜的进展。The differentiation progress of xylem cell consists of two progresses,one of which is closely related to other,programmed cell death and construction of secondary cell wall.The studies of the two progresses were respectively done,both they advanced greatly on cell biology and molecular biology.The studies on secondary cell wall were for a long time,and advanced more greatly than that on PCD.The studies on the dedifferentiation were less than the differentiation,and advanced significantly.
