Abstract: Genetic structure of seven populations in Larix kaempferi in Japan was studied by use of cpSSR markers. Ten different length fragments in and ten different kinds of haplotypes were reduced in 197 samples based on 3 pairs of polymorphic primers screened from 11 pairs of primers. There were significant variant haplotypes among the populations. The genetic variation in the populations of Larix kaempferi was detected by using cpSSR with the number of average loci A=3.33, the number of average efficient loci NE=1.20, gene diversity HE=0.17 and 5.37% variation from different populations. The genetic variation was mainly from individuals in population.

植物分类学报 , 1997,
Abstract: This study analyzed five varieties of P. tomentosa and their putative parents, P. alba, P. davidiana, P. adenopoda and P. tremula by RAPD and artificial cross. Of 78 bands revealed by 13 arbitrary primers selected, 58(74.36%) bands were polymorphic among P. tomentosa and four putative parents. The RAPD statistical results showed the relationship between P. tomentosa and P. alba or P. adenopoda was closer than that between P. tomentosa and'P. davidiana or P. tremula . There were higher similarity and lower genetic distance between P. tomentosa and P. alba or P. adenopoda than that between P. tomentosa and the other two putative parents. The results from UPGMA, Fitch-margoliash phylogenetic dendrogram were similar. In addition, artificial hybrids including reciprocal cross between P. alba and P. adenopoda were used to compare with five varieties of P. tomentosa . And those hybrids between P. alba as female and P. adenopoda as male were closer to P. tomentosa than those from reciprocal cross. The results demonstrated that P. tomentosa was a natural hybrid between P. alba as female parent and P. adenopoda as male parent.

Abstract: Considerable knowledge about the biology of forest tree has been gained in the recent years by the application of the new genomic technologies to study tree growth and development as well as the response of trees to biotic and abiotic stresses. Proteomics is becoming an important content in the biology of forest tree. A review is given about the progress in forest tree proteomics research in the areas of population genetics, genetic mapping, stress physiology, organs and tissues, and wood formation, etc. Furthermore, forest tree proteome database is briefly introduced. Finally, the prospect of proteomics is discussed.

Abstract: Comparative genomics is one of the important research fields in genomics. By comparative genomic studies it was possible to establish a giant genetic system beyond one species which might be significant to tree. Comparative ge- nomics in Salicaceae, Pinaceae, Rosaceae, Fagaceae and Hamamelidaceae had shown that the organization of genomes remained highly conserved over long evolutionary periods and extensive synteny or collinarity or microcollinarity existed in tree genomes. A total of 13 019 pairs of orthologs were identified between genes in Populus and Arabidopsis using the best bidirectional Basic Local Alignment Search Tool (BLAST) hits, with an average mutual coverage of these alignments equal to 93%; 11 654 pairs of orthologs had greater than 90% alignment of gene lengths. The progress of comparative genomics in tree species was reviewed and the prospect of this field was discussed, which might be useful to tree genomics in China.

Abstract: 忽地笑Raised Secondary Lateral Veins(RSLV)突变体平行脉间横向二级侧脉显著凸起,生长不良,雄蕊完全退化。本研究利用表达型噬菌体载体ZAP构建了野生型和突变体忽地笑叶片cDNA文库,分别随机挑取cDNA克隆进行5′端测序,共得到3,122条有效ESTs。利用这些ESTs序列,选择非冗余基因,设计512条70mer的特异性序列为寡核苷酸探针,制作芯片,对忽地笑野生型和突变体叶器官进行基因表达谱分析。进一步采用实时定量PCR技术验证芯片实验结果,最终确定所检测的基因中,有5个基因在突变型和野生型间表达差异显著,分别是韧皮部蛋白2(phloem protein2,PP2)、铁蛋白(ferritin)、果胶甲酯酶(pectin methyl esterases,PMEs),以及叶绿素a/b结合蛋白和丙酮酸脱羧酶等。克隆获得了其全长cDNA,并探讨了这些差异基因与忽地笑突变型形成的可能关系。

Abstract: The composition of molecular species and the positional distribution of fatty acids of phosphatidylglycerol (PG) isolated from Ginkgo leaf were examined and analyzed by high-perfor-mance liquid chromatography (HPLC) and enzymic hydrolysis. The fatty acid compositions (sn-1/ sn-2) of the identified major mglecular species were 18:3/16: 1(30,18:3/16:0,18:2/16: 1(3t),18:2/16:0,18:1/16: 1(3t,16:0/16:1 (3t), 18: 1/18: 1,18:1/16:0 and 16:0/16:0. The results showed that C18 fatty acids were principally localized at the sn-1 position, the component 16:1 (3t exclusively occupied the sn-2 position and 16:0 was found at both the sn-1 position and the sn-2 positon. The degree of unsaturation at the sn-1 postion was higher than that at the sn-2 positon.
