that <strong>the</strong> Chinese samples originated from <strong>the</strong> USA. A genetic diversity gradient was observed from <strong>the</strong> sampling localities in China: sites from <strong>the</strong> lower Yangtze River showed <strong>the</strong> most genetic diversity with 2 co‐occurring haplotypes, while only a single haplotype was observed in some sites far from <strong>the</strong> estuarine of Yangtze River. This biogeographic pattern was consistent with an anecdotal report that Chinese samples of P. Clarkii were first introduced in<strong>to</strong> Nanjing <strong>and</strong> neighboring cities in <strong>the</strong> lower Yangtze River by <strong>the</strong> Japanese army during <strong>the</strong> World War II. Future sampling from Japan will provide more detailed genetic information about colonization his<strong>to</strong>ry of P. Clarkiiamong China, Japan <strong>and</strong> <strong>the</strong> USA. Population genetic diversity <strong>and</strong> demographic his<strong>to</strong>ry of two freshwater crabs (Sinopotamon acutum<strong>and</strong>S.shensiense) endemic <strong>to</strong> China F FANG, HY SUN,YK JI, Q ZHAO<strong>and</strong>W GAO freshwater crabs experienced rapid population expansion since 0.1 Ma, corresponding <strong>to</strong> <strong>the</strong> warm <strong>and</strong> humid climate after <strong>the</strong> retreat of <strong>the</strong> last extensive glacial period (0.5‐0.175 Ma). We calculated significant among‐population structure for both species (S. acutum: Φ ST =0.919, P< 0.001; S.shensiense: Φ ST =0.707, P< 0.001). In conclusion, climate fluctuations may have played important roles for genetic diversity <strong>and</strong> population his<strong>to</strong>ry of S. acutum<strong>and</strong>S. shensiense. Additionally, <strong>the</strong> present habitat loss <strong>and</strong> fragmentation in distribution range could make influence on diversity <strong>and</strong> distribution of <strong>the</strong>se 2 freshwater crabs. Special protection measures should be taken because of <strong>the</strong>ir genetic uniqueness <strong>to</strong> preserve <strong>the</strong>ir genetic diversity.

The genetic diversity <strong>and</strong> genetic structure of an endemic Sinopotamonacutum<strong>and</strong>S. shensiense are true freshwater Chinese freshwater crab, Sinopotamonhonanense, were crabs endemic <strong>to</strong> China, both of which have a sympatric investigated by analyzing 9 microsatellite loci for 485 distribution along <strong>the</strong> Qingling–Daba Mountains. We samples collected from 28 localities across current combined maternally inherited mtDNA <strong>and</strong> biparentally distribution range of species. Basic statistics showed that inherited microsatellite DNA <strong>to</strong> explore <strong>the</strong> genetic <strong>the</strong> mean overall values of H O <strong>and</strong> H E were diversity <strong>and</strong> demographic his<strong>to</strong>ry of S. 0.6125±0.2250 <strong>and</strong> 0.6402±0.1538, respectively.

from mutation‐drift equilibrium with heterozygote deficiency under <strong>the</strong> TPM <strong>and</strong> SMM model using <strong>the</strong> program BOTTLENECK. These results suggested that <strong>the</strong> S.honanense population did not experience <strong>the</strong> recent population bottleneck. The estimated gene flow was provided by population graph <strong>and</strong> migrate analysis which showed strong gene flow among populations across <strong>the</strong> S. honanense‘s distribution range in northward direction (t = 4.341, P < 0.001). Fur<strong>the</strong>rmore, significant long‐distance dispersal event occurred from <strong>the</strong> sou<strong>the</strong>rnmost <strong>to</strong> nor<strong>the</strong>rnmost possibly due <strong>to</strong> male‐mediated gene flow (t = 3.051, P< 0.01). The preponderance of <strong>the</strong>se data suggested that <strong>the</strong> recent population continuous expansion was largely due <strong>to</strong> a northward shift in <strong>the</strong> climate transitional zone, in which S. honanensecan maintain positive population growth. And <strong>the</strong> male crabs played major role in <strong>the</strong> long‐distance migrations. Structure changes of initial chi<strong>to</strong>san <strong>and</strong> chi<strong>to</strong>san derivatives were confirmed by FT‐IR spectroscopy. The IR spectra of chi<strong>to</strong>san oligomers showed <strong>the</strong> characteristic absorption peaks of saccharide units while many fine absorption peaks compared with <strong>the</strong> initial chi<strong>to</strong>san. These results revealed that different low molecular weights of chi<strong>to</strong>san oligomers could be prepared by this simple but effective procedure, which may open new perspectives in fields of food, pharmaceutical <strong>and</strong> cosmetic due <strong>to</strong> its excellent special biological functions such as antitumor activity, immune‐enhancing activity <strong>and</strong> antifungal activity.

Email: zhanggr@mail.sysu.edu.cn Chi<strong>to</strong>san oligomers, derivatives of chi<strong>to</strong>san with low molecular weights, are characterized by improved water‐solubility <strong>and</strong> some special biological functions. Chi<strong>to</strong>san is a derivative of deacetylation chitin extracted from <strong>the</strong> larval cuticles of Chrysomyia megacephala, a widespread necrophagous fly, by chemical treatments. In this work, Chi<strong>to</strong>san oligomers with different molecular weights were successfully prepared by chi<strong>to</strong>san oxidative degradation involving hydrogen peroxide (H 2 O 2 ). Effects of concentration of H 2 O 2 , reaction temperature <strong>and</strong> degradation time on <strong>the</strong> molecular weights of chi<strong>to</strong>san oligomers were studied, discovering <strong>the</strong> optimum conditions (5% H 2 O 2 , 70 ℃ <strong>and</strong> 3 h) of procedure determined on <strong>the</strong> basis of orthogonal tests. End group analysis was employed <strong>to</strong> measure <strong>the</strong> number‐average molecular weights of <strong>the</strong> products, which exhibited a broad range (46–0.34kDa) of low molecular weights.

Email: songxy@qau.edu.cn Oil, protein <strong>and</strong> starch content are main agronomic characters in maize. In this paper, 278 of F 2:3 individuals derived from <strong>the</strong> cross between inbreds LX00‐6 <strong>and</strong> E28 were used for developing <strong>the</strong> mapping population. Genetic linkage map with simple sequence repeat markers had been established <strong>to</strong> detect QTLs affecting nutritional quality. The main results were as follows:The correlation analysis of <strong>the</strong> nutritional quality characters indicated that oil content of <strong>the</strong> F 2:3 populations was positively correlated with protein <strong>and</strong> starch content, while starch content was negatively correlated with protein content. In a word, we could not improve <strong>the</strong> oil, protein <strong>and</strong> starch in maize simultaneously. Oil content about 3 <strong>to</strong> 4 percentage, <strong>to</strong>ok up 44.24 percentage in F 2:3 population, oil content about 4 <strong>to</strong> 5 percentage, <strong>to</strong>ok up 55.40 percentage <strong>and</strong> oil content over 5 percentage only <strong>to</strong>ok up 0.36 percentage, oil content usually distributes 3 <strong>to</strong> 5 percentage. Protein content distributing 11 <strong>to</strong> 12 <strong>to</strong>ok up 49.28 percentage, protein content over 14 percentage <strong>to</strong>ok up 0.72 percentage <strong>and</strong> <strong>the</strong> protein content below 9 percentage <strong>to</strong>ok up 0.36 percentage; <strong>the</strong> protein content usually distributes 10 <strong>to</strong> 13 percentage.
