The comparative analysis of electronic expression profile of zfand5a gene from zebrafish, house mouse and pig that has high sequence homologies with zjp123 gene from P. olicaceus were carried out. Several conserved domains and motifs were discovered by the primary and secondary structure analyses. Zinc fingerlike tertiary struclure "C-Xasubscript (2-4-C-X11-C-X2-C" was shown by homology modeling.
电子表达谱分析分别对与ZFP123有较高同源性的斑马鱼、家鼠和猪的zfand5a(zfp123)基因各个组织表达情况进行了比较分析;一、二级结构分析发现其具有多个保守的基序和结构域;同源建模显示其具有一个&C-X下标(2-4-C-X11-C-X2-C&结构的锌指样三级结构。

It is an ancient species in its own genus and well-adapted to drought environments with fissurate growth and summer dormancy. Methods We selected Dengkou as our research site and collected three stages of P. mongolica (before, during and after fissuration) during August 1-5, 2002 and 2003. We used PV technique and measured several water relations parameters (φ,φ, ROWC, RWC,△(subscript φ),ε etc. in different stages of fissurate growth for comparison and analysis of drought tolerance and its mechanisms. Important findings Different stages of P. mongolica had different abilities and pathways to maintain turgor pressure. Fissurate growth decreased the species' drought tolerance and involved multiple adaptations to drought.

The results showed that: the explants of strawberry leaves were rather sensitive to kanamycin, and the corresponding concentration of 20 mg/L could substantially inhibit the growth of non-transformed tisse and be used to screen the leaves of strawberry after transformation. Timentin at the concentration of 300 mg/L could be used to eliminate Agrobacterium tumefaciens and had minor impact on the growth of the explants. The preculture time of 2-4 days was beneficial to improve transformation frequency. Co-culture for 2-3 days not only had higher gus transient expression but also avoid the over-growth of agrobacterium. The bacterial concentration of OD(subscript 600nm) 0.4 was the best inoculum density and 10 minutes was the best inoculation time.
结果表明:草毒叶片外植体对卡那霉素较为敏感,适宜的筛选浓度为20mg/L,可明显抑制非转化组织的生长;300mg/L的羧吩青霉素可有效抑菌,对外植体生长影响也较小;预培养2-4d有利于转化;共培养2-3d有利于提高转化频率并避免了农杆菌的过度生长;OD(下标 600nm)值为0.4的菌液侵染10min效果最佳。
