植物的联会复合体(Synaptonemal complex,简称SC)铺展技术,是近年来发展起来的技术,由于具有光镜检查快和电镜高分辨率的双重优点,又能观察偶线期核的染色体配对状态,不仅在交换的机理研究中得到大量应用,同时成为染色体结构变异研究中的强有力的手段.目前主要的作物如玉米、小麦、大麦等有关的研究均已有报道,但是在水稻细胞遗传学研究中,至今未见有关铺展SC的研究.我们在水稻的花粉母细胞中,应用铺展技术观察晚偶线期一早粗线期的联会复合体. Plant Synaptonemal complex (SC) spreading technology is a technique developed in recent years. Due to its advantages of fast light microscopy and high resolution of electron microscope, it can also observe the chromosome pairing status , Not only has been widely used in the study of exchange mechanism, but also become a powerful means in the study of chromosome structure variation.At present, the research on major crops such as corn, wheat and barley has been reported, but in rice cytogenetics No studies on spreading SC have been found up till now.In the pollen mother cells of rice, we observed the synaptonemal complex in the late even period, the early morning, and the thick period by spreading technique.
