A_2V4/B_2V4 were used in our program to study the chromosomal behaviors during meiotic division and tapetumal change during anther development in A_2 cytoplasmic-male sterile(CMS).
以A2V4/B2V4为材料,对A2类型雄性不育系的减数分裂过程中染色体行为和花药发育过程中绒毡层的变化进行了细胞学观察研究。
3) chromosome genetic behavior
染色体遗传行为
4) Abnormal chromosomal behavior
染色体行为异常
1.
Abnormal chromosomal behavior of root tip cells emerged when the NaCl concentration was more than 100 mmol/L.
结果表明,随着NaCl浓度的升高,旱稻的发芽率、发芽指数、活力指数逐渐降低;NaCl浓度高于100 mmol/L时,引起根尖细胞染色体行为异常,异常类型有微核、多核、染色体落后、染色体粘连、染色体桥、染色体断裂等。
5) chromosomal abnormal behavior
染色体异常行为
1.
Observation of the variation of the chromosomal behavior in second Filial generation during meiosis is made on the hybrid of wheat -rye 5R/5A disomic substitution line and 6R/6A disomic substitution line, and the chromosomal abnormal behavior and the coherency with chromosomal translocation are analyzed.
所以,在减数分裂过程中出现单价体、多价体、落后染色体、微核等染色体异常行为,这些现象会影响染色体配对、交换,对研究染色体易位的形成能提供重要依据。
