Crystal structures were formed by the copies of DNA, and the radio-shape of the crystal structure resulted from the continuous copies of amyloplast DNA in the development stages.
DNA复制形成了晶体结构(晶体核)以及辐射状的晶体结构，这是淀粉体dna随着发育时期的增长而不断复制的结果。
The amyloplast usually possessed a larger, very low electron density starch grain which mainly was long shuttle and there were some higher electron density partition or wedge structure in it.
它的基质很少，多含有呈长梭形的、电子密度非常低的淀粉粒，并有一些电子密度较高的条带结构。
The changes of amyloplast and amyloplast DNA in different development stages were also observed, indicating the relationship among the amyloplast core, crystal structure and the amyloplast DNA.
又系统观察了在不同发育时期淀粉体及淀粉体dna的变化，揭示了淀粉体dna与淀粉核心、晶体结构的关系。
