The study on the phylogenetic relations among these species is very useful for the study on genome and marker-assisted breeding in Brassica species. The karyotypic analysis is one of the most important methods in analysing the phylogenetic relation of species with closer relations. The protocol for inducing high frequency metaphase was established by pretreatment with low temperature and 8hydroxyquinoline, and then the preparation of chromosome and karyotypes analysis of six economical important Brassica species were carried out. According to the karyotypic analysis, it was shown that in the genomes of amphidiploid species, there are genomical components from didiploid species. Our result showed that B. campetris, B. juncea and B. napus belonged to class 2B, while B.

以二倍体B.nigra（B，n=8）基因组为探针，用B.campestris（A，n=10）或B.oleracea（C，n=9）的基因组进行封阻，分别与B.juncea（AB，n=18）和B.carinata（BC，n=17）进行GISH杂交发现，B.juncea和B.carinata基因组中仅有来自于B.nigra的8对染色体表现杂交信号，而其它染色体杂交信号较弱；以B.campestris或B.oleracea基因组为杂交探针与B.napus（AC，n=19）进行GISH杂交发现，所有19对染色体均出现杂交信号，根据杂交结果难以正确判断B.napus基因组中的哪些染色体是来自于A基因组，哪些是来自于C基因组；以rRNA基因（18S-5.8S-26S）为探针的FISH杂交结果表明，B.campestris基因组中rRNA基因位点为6对；B.oleracea为3对；B.nigra为2对；B.carinata为4对；B.juncea为6对；B.napus为6对。

This favors that amphioxus retains a genome uncomplicated by extensive gene duplication.

这支持了文昌鱼基因组没有发生广泛倍增的观点。

However, there is no report about amphioxus Rab23 up to now except the annotations of two isoforms in the genome of Florida lancelet.

目前关于文昌鱼Rab23同源基因的研究仅局限于佛罗里达文昌鱼基因组中的注释。

Genetic analysis were carried out to identify powdery mildew and strip rust resistance genes in the F2 of Am6-4 amphiploid and wheat variety Jinan17. Results showed that resistances to powdery mildew and stripe rust were controlled by a single dominant gene respectively. 124 SSR primers from genome D were used for marker analysis, marker Xgwm98 150(150为下标) from the chromosome 6D was found to be linked to the new powdery mildew resistance gene with a linkage distance 20.42 cM; A special DNA band was amplified by primere xgwm33 in resistant stripe rust plants, resistance gene for stripe rust was localized on chromosome 1D, and the genetic distance between resistance gene and marker is 8.0 cM.

利用Am6-4与济南17F2分离群体进行白粉病和条锈病抗性基因的遗传分析结果证明，Am6-4中的抗白粉病和抗条锈病基因均为单显性基因；以124对D基因组SSR引物进行标记分析，引物Xgwm98在抗白粉病DNA池和单株中能扩增出特异标记带，标记与抗白粉病基因间的遗传距离为20.42cM，并将抗白粉病基因定位于6D染色体；引物Xgwm33能在抗条锈病DNA池和单株中扩增出特异标记带，标记与抗条锈病基因间的遗传距离为8.0cM，并将抗条锈病基因定位于1D染色体。

We identified 53 genes encoding protein Ser/Thr or Tyr kinases on the genome of Anabaena sp.

Genome sequences of Anabaena PCC 7120 are available at the CyanoBase databank.

Anabaena PCC7120的全基因组序列可以从CyanoBase数据库获得。

Using Pseudomonas syringae and Pantoea ananas , the dominant ice nucleation active bacteria strains from Yunnan province, as receptors of genetic engineering recombination, and Escherichia coli S17/pZJ25∶∶Tn5 as donator. By transposon Tn5 induced mutants method, the Tn5 was inserted and integrated into the genome of wild type INA + bacteria. INA + mutant as INA - when the linear continuous of INA + gene destroyed.

以云南省冰核细菌的优势种类丁香假单胞菌Pseudomonassyringae和菠萝泛菌Pantoeaananas为重组基因工程菌的受体菌，采用Tn5转座子诱变技术，以大肠杆菌EscherichiacoliS17/pZJ2 5∶∶Tn5作为转座子诱变的供体菌，使Tn5插入并整合到冰核细菌基因组中，使冰核基因的线性连续性被破坏，失去冰核活性。
