大蒜根尖分生组织细胞中期染色体蛋白主要有19条蛋白质谱带，它们的分子量约在14～97kd．用Jeppesen介绍的方法抽提得到的组蛋白，经电泳检测发现有6条谱带，包括2种H1和4种小分子量组蛋白（H3、H2b、H2a、H4）．染色体骨架蛋白中，37kd、38kd、40kd和43kd4种蛋白质成份较为清楚，可以认为是中期染色体骨架的主要成份． Garlic apical meristem cells metaphase chromosome protein has 19 protein bands, their molecular weight of about 14 ~ 97kd. The extracted histones were extracted by the method described by Jeppesen. Six bands were found by electrophoresis, including two kinds of H1 and four small molecular weight histones (H3, H2b, H2a, H4). Chromosome skeletal protein, 37kd, 38kd, 40kd and 43kd 4 kinds of protein components more clearly, can be considered as the main component of the metaphase chromosome skeleton.
