After 14 year's growth observation on the plant growth, it was found that obvious segregation appeared among the haploid pollen plants obtained from anther culture of Populus Xiaohei T.S. Hwany ex C. Wang et Tung in vitro. By vegetative propagation, 19 clones were selected and field contrast test was carried out. Statistical analysis result showed a significant difference in volume production. They are superior clones which could be selected from among the pollen plants for utilization. A haploid breeding procedure is suggested in the paper.

Comparative Proteomic Analysis of IBA-Induced Proteins during Adventitious Root Organogenesis of larch

第二届中国林业学术大会——S2 功能基因组时代的林木遗传与改良

作者： Yanguang Chu Xiaohua Su Qinjun Huang Xianghua Zhang (Research institute of forestry, Chinese academy of forestry Key laboratory of Tree breeding and Cultivation, State forestry Administration Beijing 100091)

Black poplar (Populus nigra L.) is an economically and ecologically important tree species and an ideal organism for studies of genetic variation. In the present work, we use a candidate gene approach to infer the patterns of DNA variation in natural populations of this species. A total of 312 single nucleotide polymorphism (SNP) sites are found among 8056 bp sequenced from nine drought-adaptation and photosynthesis-related gene loci. The median SNP frequency is one site per 26 bp. The average nucleotide diversity is calculated to be θW=0.01074 and πT=0.00702, higher values than those observed in P. tremula, P. trichocarpa and most conifer species. Tests of neutrality for each gene reveal a general excess of low-frequency mutations, a greater number of haplotypes than expected and an excess of high-frequency derived variants in P. nigra, which is consistent with previous findings that genetic hitchhiking has occurred in this species. Linkage disequilibrium is low, decaying rapidly from 0.45 to 0.20 or less within a distance of 300 bp, although the declines of r2 are variable among different loci. This is similar to the rate of decay reported in most other tree species. Our dataset is expected to enhance understanding of how evolutionary forces shape genetic variation, and it will contribute to molecular breeding in black poplar.

Gymnosperms,especially conifers,are of great interest for reforestation and most importantly for pulpwood.A lack of competence to form adventitious roots by cuttings occurs commonly and is an obstacle for the vegetative propagation and rapid fixation of elite genotypes. Molecular mechanism of root induction by auxins is complex,and to a large scale,the genes involved remain unknown and their expression *** this study,the process of adventitious root organogenesis of Larix kaempferi(Lamb.) *** investigated and which could be divided into three stages-adventitious root induction,adventitious root primordia initiative cell formation and adventitious root primordia *** level changes accompanied with adventitious root development,the effect of exogenous IBA on adventitious root development is mainly increasing the content of endogenous IAA in the induction stage of adventitious root *** this,protein abundance was measured using two-dimensional polyacrylamide gel electrophoresis(2-DE) in water- and IBA-treated stem cutting samples and 33 proteins were identified by MALDI-TOF/TOF *** proteins related to various biological metabolisms such as photosynthesis,respiration,signal transduction,cell division and differentiation which were important for adventitious root *** of proteins- malate dehydrogenase and cytochrome c oxidase subunit 6b changed statistically significant after IBA *** full-length cDNA of LkMDH and LkCcO6b were isolated and qRT-PCR experiments indicated the differential expression of these genes by IBA treatment during adventitious *** together,these results will help understanding of the molecular mechanism of adventitious root formation in *** which can be used for other conifer species.

The Bacillus thuringiensis vegetative insecticidal protein, Vip3 A, represents a new family of Bt toxin and is currently applied to commercial transgenic cotton. To determine whether the Cry1Ac-resistant Helicoverpa armigera is cross-resistant to Vip3 Aa protein, insecticidal activities, proteolytic activations and binding properties of Vip3 Aa toxin were investigated using Cry1Ac-susceptible（96S） and Cry1Ac-resistant H. armigera strain（Cry1Ac-R）. The toxicity of Vip3 Aa in Cry1Ac-R slightly reduced compared with 96 S, the resistance ratio was only 1.7-fold. The digestion rate of full-length Vip3 Aa by gut juice extracts from 96 S was little faster than that from Cry1Ac-R. Surface plasmon resonance（SPR） showed there was no significant difference between the binding affinity of Vip3 Aa and BBMVs between 96 S and Cry1Ac-R strains, and there was no significant competitive binding between Vip3 Aa and Cry1 Ac in susceptible or resistant strains. So there had little cross-resistance between Vip3 Aa and Cry1 Ac,Vip3A＋Cry proteins maybe the suitable pyramid strategy to control H. armigera in China in the future.

Transpiration rate and ion distribution of pagoda tree, walnut, velvet ash and poplar seedlings treated by NaCl solution of 0, 50, 100, 200 mmol·L-1 were studied. The results showed that there were significant differences in the response to NaCl among the four tree species. Na+ exclusion capacity of pagoda tree was the largest among the four species. The Na+ exclusion capacity of velvet ash was less than that of pagoda tree. Salt excretion capacity of velvet ash was limited. Its salt-tolerance was bigge...
