常染色体

Granulosus is further;2. In differentiation of closely relatedspecies, the changes in heterochromatin and pericentric inversions are key factors, this is wellnoted in the small chromosomes;3. A. mantzorum has well-differentiated XY type sex chromo-'.omes, the Y chromosome is mainly composed of euchromatin, but has strong C-band in themiddle of the long arm. It is suggested that the Y chromosome of A. mantzorum is in the-initial stage of sex chromosome differentiation.

结果表明：(1)四川湍蛙、理县湍蛙和棕点湍蛙之间的亲缘关系较近，而它们与棘皮湍蛙的亲缘关系较远；2）在近缘种的分化中，染色体结构异染色质的变化和臂间倒位是重要的因素之一，这在小型染色体上表现得尤为突出；四川湍蛙具有在形态上分化很明显的性染色体。C带分析表明，此性染色体主要由常染色质构成，但在其Y染色体的长臂上存在明显的中间C带，推测尚处于性染色体分化的初期阶段。

The laboratory findings of a typical CCML patient comprised of peripheral blood leukocytosis, basophilia and eosinophilia,myeloid differentiation in different stages, and increased megakaryocytes. The immunohistochemical features of the CCML consisted of highly positive MPO and CD68, significant lowering of neutrophil alkaline phosphatase, positive for Philadel- phia chromosome or chimeric BCR/ABL gene, etc. But in most cases of juvenile CCML, the Philadelphia chromosome could not be detected.

临床表现以乏力、低热、贫血、肝脾及淋巴结肿大为主要特点；典型儿童慢性髓细胞白血病的实验室特点有白细胞计数高、嗜酸和嗜碱性粒细胞增多、骨髓不同阶段髓细胞分化和巨核细胞增多；免疫组化提示CD68，髓过氧化物酶，中性粒细胞碱性磷酸酶积分明显减低，Ph染色体或BCR/ABL融合基因阳性，而幼年型CCML的Ph染色体常为阴性。

The signals look like noncontinuous beads on the DNA fiber,which consist of multi-copy and arrange tandemly.Fiber-FISH results with 45S rDNA probe showed that an average signal length is about 3～11μm in many tandem copy sequence(measure number,n=8),so we estimated the size of each copy to be approximately 11～30kb in cotton genome.There are dual signals on each end of the mitosis metaphase chromosomes and pachytene chromosomes hybridized with telomere DNA probe.The signals also look like non-continuous beads on the DNA fiber,the length is about 1～9μm,so we estimated the size is about 4～27kb.The signals almost covered the whole mitosis metaphase chromosomes and pachytene chromosomes of G.arboretum Shixiya 1 hybridized with gDNA probe,the euchromatin zone and heterochromatin zone were identified clearly on pachytene chromosomes,and the signals also look like non-continuous beads.Two BAC clones 150-D-24 and 182-F-9 in DNA BAC library of Pima90 were selected as probe to hybridize with mitosis metaphase chromosomes,pachytene chromosomes and DNA fiber of G.raimondii.

棉花FISH技术系统的应用研究。45S rDNA在亚洲棉石系亚1号中期和粗线期染色体上有两对大的信号，在DNA纤维上信号为非连续的念珠状，多个拷贝串联排列，每个拷贝长度大约在3～11μm，推测每个拷贝的实际长度为11～30kb；端粒序列在亚洲棉石系亚1号中期和粗线期染色体端部都有双点信号，在DNA纤维上信号也为非连续的念珠状，不同染色体上信号长度大约在1～9μm不等，推测实际长度为4～27kb；gDNA信号几乎布满整个亚洲棉石系亚1号中期和粗线期染色体，在粗线期染色体上能明显区分出常染色质区和异染色质区，DNA纤维上的信号均为非连续的念珠状。
