The Arabidopsis anaphase-promoting complex/cyclosome subunit 8 is required for male meiosis
Arabidopsis thaliana APC/C chromosome segregation meiosis spindle assembly
2023/8/9
Faithful chromosome segregation is required for both mitotic and meiotic cell divisions and is regulated by multiple mechanisms including the anaphase-promoting complex/cyclosome (APC/C), which is the...
Effect of Brassinolide Applied at the Meiosis and Flowering Stages on the Levels of Endogenous Plant Hormones during Grain-Filling in Rice Plant (Oryza sativa L.)
Abscisic acid(ABA) Brassinolide(BL) Ethylene Indoleacetic acid(IAA) Low temperature(L-temp) Milk-ripe stage Panicle Rice
2009/7/29
Brassinolide (BL), a brassinosteroid, applied to rice plants in pots promotes panicle ripening. In this study, we examined the effect of BL applied at the meiosis and flowering stages on endogenous le...
The Influence of Phosphate Treatment on Chromosome Segregations and Tetrad Regularity and Using Tetrads in Determination of Regular Meiosis Diploid and Autotetraploid Meadow Fescue（Festuca pratensis Huds）

This study was carried out under greenhouse conditions in 1994-1995. The influence of phosphate treatments (0, 1, 2, 3 and 4g P 2 O 5 /pot) on chromosome segregaiton at the first anaphase (AI) and tet...
家猪减数分裂粗线期二价体与有丝分裂中期染色体的比较研究Comparative Studies on Meiosis Pachytene Bivalents and MitosisCMetaphase Chromosomes of Pig (Sus scrofa domestica)
家猪 二价体 有丝分裂染色体 染色粒结构带 G-带
2008/1/30
摘要以性成熟公猪睾丸和外周血为材料，采用长低渗、高氯仿卡诺固定液固定和外周血细胞培养制备减数分裂粗线期二价体和有丝分裂中期染色体，通过对二价体和有丝分裂中期染色体分裂指数和长度的比较研究，发现二价体的分裂指数和长度分别是有丝分裂中期染色体的5倍和3.42倍(1.87～5.98)；同时以12号染色体为例, 比较了二价体上的染色粒结构带与有丝分裂中期染色体G-带，表明染色粒结构带比中期染色体G-带带纹...
