These findings indicated that ATPase played a key role on the cell wall formation of fiber in Phyllostachys edulis culm, and the formation of secondary wall was a typical programmed cell death ( PCD ), which was an energy dependent active process and was controlled by nuclear genes. 结果表明,ATP酶在毛竹茎秆纤维细胞壁的整个形成过程中发挥重要作用,而纤维细胞的次生壁形成过程是一个由核基因控制的主动的PCD过程;
