研究了[14C]葡萄糖在玫瑰花（Catharanthus roseus， L.）细胞壁各部位及各部位糖组分中的结合率。为了阐明在细胞周期中细胞壁的合成方面。放射性掺入的变化与每个细胞壁部分的量的变化以及先前报道的糖组成的变化密切相关（S. Amino等）。杂志。植物。60:326-332,1984)。在整个细胞周期中，半乳糖的比活性高于其他糖，并且在细胞数量增加之前，除了纤维素外，所有细胞壁组分的放射性结合都暂时增加。其合成活性可能对细胞周期中细胞壁多糖的动态调节起关键作用。
The incorporation rates of [14C] glucose into various fractions of the cell walls and into the sugar constituent of each fraction were investigated in a synchronous culture of Catharanthus roseus (L.) G. Don in order to elucidate the synthetic aspects of the cell walls during the cell cycle. Changes in the incorporation of radioactivity were closely correlated with changes in the amount of each cell wall fraction as well as with those in sugar composition as reported previously (S. Amino et al. Physiol. Plant. 60: 326–332, 1984). The specific activity of galactose was higher than that of other sugars throughout the cell cycle, and a temporary increase in the incorporation of radioactivity into all cell wall fractions except cellulose was observed just before the increase in cell numbers. The synthetic activities may play key roles in the regulation of cell wall polysaccharide dynamics during the cell cycle.
