Rice is the staple food for more than half of the world population. The utilization of the wild abortive cytoplasmic male sterility (CMS) in 1970s has significantly raised rice yield potential. But the world's annual rice production will have to increase 70 percent over the next 30 years, to keep up with the demends of the growing population.

Objective: To study the function of augmenter of liverregeneration (ALR) as a regulatory factor that specif-ically stimulates hepatic cell regeneration, we con-structed yeast expressive vector of ALR and expressedit in yeast ***: Total RNA was extracted from HepG2 cells,and reverse transcription polymerase chain reaction(RT-PCR) was performed to amplify the coding re-gion of ALR. The products were cloned into pGEM-Tvector and sequenced, then cloned into pGBKT7 vec-tor. The recombinant plasmid pGBKT7-ALR wastransformed into yeast AH109. The yeast protein wasextracted and analyzed by SDS-polyacrylamide gelelectrophoresis (SDS-PAGE) and Western blottinghybridization ***: DNA sequencing results confirmed that thecoding region of ALR was correctly inserted into theyeast expression vector, and Western blotting assayshowed that recombinant ALR was successfully ex-pressed in yeast. Its molecular weight was identical tothe theoretical value of 15,000 Da; the protein wasfound inside the yeast ***: The successful expression of ALR in yeastcells makes it possible to study further on its biologicalfunction.

通达性是度量交通网络结构的有效指标，但较少被用于民国时期铁路交通的研究。通过将民国时期铁路线路图数字化，结合铁路旅行时间、客货运输量等数据，分析民国时期中国铁路交通网络通达性变迁。结果表明：铁路建设以北京为中心，华北地区成为全国的通达性中心区；东北和华北地区的铁路客运、货运量大于其他地区，随着国民政府迁都南京和长三角地区的经济发展，华东和华南地区铁路客运、货运量明显增大，东西之间的联系也逐渐增强；铁路客货运量与铁路沿线城市人口数量具有较强的相关性，铁路运输促进城市规模的增长。民国时期中国铁路在路权、路政和技术等方面都存在复杂性问题，铁路交通呈现出区域通达性较好，全国通达性差的特征。

The authors processed the seismic refraction Pg-wave travel time data with finite difference tomography method and revealed velocity structure of the upper crust on active block boundaries and deep features of the active faults in western Sichuan Province. The following are the results of our investigation. The upper crust of Yanyuan basin and the Houlong Mountains consists of the superficial low-velocity layer and the deep uniform high-velocity layer, and between the two layers, there is a distinct, and gently west-dipping structural plane. Between model coordinates 180-240 km, P-wave velocity distribution features steeply inclined strip-like structure with strongly non-uniform high and low velocities alternately. Xichang Mesozoic basin between 240 and 300 km consists of a thick low-velocity upper layer and a high-velocity lower layer, where lateral and vertical velocity variations are very strong and the interface between the two layers fluctuates a lot. The Daliang Mountains to the east of the 300 km coordinate is a non-uniform high-velocity zone, with a superficial velocity of approximately 5 km/s. From 130 to 150 km and from 280 to 310 km, there are extremely distinct deep anomalous high-velocity bodies, which are supposed to be related with Permian magmatic activity. The Yanyuan nappe structure is composed of the superficial low-velocity nappe, the gently west-dipping detachment surface and the deep high-velocity basement, with Jinhe-Qinghe fault zone as the nappe front. Mopanshan fault is a west-dipping low-velocity zone, which extends to the top surface of the basement. Anninghe fault and Zemuhe fault are east-dipping, tabular-like, and low-velocity zones, which extend deep into the base-ment. At a great depth, Daliangshan fault separates into two segments, which are represented by drastic variation of velocity structures in a narrow strip: the west segment dips westward and the east segment dips eastward, both stretching into the basement.
