A novel synthetic approach of 3,3'-azobis(6-amino-1,2,4,5-tetrazine) was firstly devised. Taking 3,6-bis(3,5-dimethylpyrazol-1-yl)-1,2,4,5-tetrazine as a primary material, DAAT was synthesized by high pressure ammonolysis and potassium permanganate oxidation. Compared with the four-step reaction in the literature, this new approach was reduced to two steps with a yield of 58.1%. The intermediate and DAAT were characterized by elemental analysis, IR and NMR spectra.

自行设计了3，3'-偶氮双(6-氨基-1，2，4，5-四嗪)新合成路线、采用3，5-双(3，5-二甲基吡唑-1-基)-1，2，4，5-四嗪为原料，由文献报道的4步反应缩减为2步，经高压氨解、高锰酸钾氧化合成了DAAT，总收率大幅提高，达到58.1%，并采用元素分析、红外光谱、核磁共振光谱等进行了结构表征。

在此，我们把这种新的方法与四种已经建立的基于重量水分吸附技术的测定无定形组分的

Nigra, B. oleracea and B. carinata belonged to class 2A according to the classification of karyotypes by Stebbins (1971). According to Levitzky's and Stebbin's view, the more asymmetric karyotype a species has, the more evolved it is. Therefore, B. campestris is the furthest evolved species among the elementary species, and B. juncea and B. napus the furthest among the amphidiploid species. Compared with the previous reports, there is no any cytoplasm in the chromosome sample prepared using this protocol which is very useful for the karyotype analysis, as well as the FISH research on Brassica species.

对上述研究结果分析表明：（1）芸薹属复合种是由基本种相互杂交而成；（2）B基因组与A或与C基因组亲缘关系较远，而A和C基因组亲缘关系较近；（3）芸薹属复合种在演化过程中，发生了染色体结构上的重排现象；（4）芸薹属复合种演化过程中，rRNA基因位点发生了减少；所获结果与国外同类报道相比表明：国内的白菜型油菜存在新的rRNA基因位点，即rRNA基因在芸薹属同一物种不同的品种间具有多态性；有关这类研究国内尚未见报道。

Longitudinal root sections of the wild type and the gls mutant cultured in nutrient solution for 4 days showed that biosynthesis and distribution of amyloplast in the columella cells of gls were normal as compared with the wild type, suggesting that root gravitropism loss in gls mutant is not caused by the defect in amyloplast sedimentation, but possibly by the disturbance of auxin transport and distributation.

4天龄的根系纵切片结果显示：突变体gls根尖结构完整，根尖柱细胞内淀粉粒的生成和分布正常，表明gls突变体根系向地性的缺失不是由于淀粉体的原因，而可能通过影响生长素运输和分布造成。
