By Giemsa--C technique, the chromosomes of Aegilops tauschii (85A-34) and Hordeum vulgare (H2) and Ae.tauschii- H.vulgare amphidiploid were all produced clear bands, the terminal band, centromeric band, secondary constrition band and rich intercalary bands were displayed distinctly, thus the corresponding Giemsa-C banding patterns were confirmed.

利用Giemsa--C带显带技术，节节麦、大麦、节节麦-大麦双二倍体都显示出了清晰的带纹，都具有端带、着丝点带、随体带和丰富的中间带，相应的确定了它们的Giemsa--C带核型。

Due to the deficiency of cyclin B1 and 〓, spermatogonia and pachytene/diplotene primary spermatocytes in contralateral cryptorchid testis were unable to form MPF, and therefore, they could not accomplish their nuclear division, and became arrested at the transition stage from mitosis to meiosis (G2/M phase). We also found that testosterone could regulate the cyclin B1 expression in spermatogenic cells.

由于cyclin B1和〓的缺失，粗线期/双线期初级精母细胞中的MPF无望形成，从而导致生精细胞分裂停滞在由有丝分裂向减数分裂过渡的G2/M相；（5）睾酮可在翻译水平上调控阴囊内睾丸生精细胞cyclin B1蛋白的表达。
