On the significance of chromosomal data in the evolutional study of Taxodiaceae.

标题 染色体资料在杉科演化研究中的意义。

Ansochromogenes was transformed by pUC1169 from itself. 8 mutants lost ability to produce nikkomycin were screened from 4068 colonies of Vio〓 Thio〓 with Tn4560 transposition. Southern blotting suggested that Tn4560 was inserted in at least 4 positions of chromosomal DNA in S.

于39℃,MM/Vio条件下培养携带有pUC1169的7100孢子,Tn4560发生转座;筛选到4068个转座菌落,并从中得到8株尼可霉素阻断突变株;对这8株突变株的总DNA进行Southern杂交分析表明,Tn4560至少在4个不同的位点插入到7100的染色体上。

Allelic loss at specific chromosomal loci is a common genetic alteration in human tumours and is thought to be critical for unmasking the recessive genetic changes for tumorigenesis.

This experiment selecetd apex , flower bud and radicle of Camellia sinensis cv. Longjing 43 as research objects picked from the tea garden of Anhui Agricultural University. In this experiment ,three kinds of Chromosomal techniques were used ,including conventional sheeting method , disassociating cell wall hypoosmotic method and macrocoils method.

本试验以安徽农业大学茶园中龙井 43 的芽尖、花蕾以及其茶籽培养的幼根为研究对象,采用传统的压片法、去壁低渗法、风油精法三种制片方法,进行系统的比较和分析,这三种方法均能找到茶树体细胞有丝分裂相。

The seeds of Adzuki bean were irradiated by 60 Co γ ray of 0~700Gy.The results showed that:(1)The sub\|lethal dose(LD 50 )was 389Gy and the early seedling leaf at M\-1 showed incised,chlorotic,yellow,mosaicand curly edge.The absorbed dose was related with the rate of misshaped leaf.Chromosomal aberration, chromosome bridge and fragment of M\-1 in the tip were observed.If the seed was irradiated with 400Gy,the rate of abnormal cell at the root was more than 10%.The relationship between pollen fertility and irradiation dose was negative correlated.
