To dissect the genetic control of the sensory and textural quality traits of Chinese white noodles, a population of recom- binant inbred lines （RILs）, derived from the cross of waxy wheat Nuomai 1 （NM1） and Gaocheng 8901 （Gc8901）, was used. The RILs were tested in three different environments to determine the role of environmental effects on quantitative trait loci （QTL） analysis. A total of 45 QTLs with additive effects for 17 noodle sensory and textural properties under three environments were mapped on 15 chromosomes. These QTLs showed 4.23-42.68% of the phenotypic variance explained （PVE）. Nineteen major QTLs were distributed on chromosomes 1 B, 1 D, 2A, 3B, 3D, 4A, and 6A, explaining more than 10% of the phenotypic variance （PV）. Clusters were detected on chromosomes 2B （3 QTLs）, 3B （11 QTLs） and 4A （5 QTLs）. The cluster detected on chromosome 4A was close to the Wx-B1 marker. Five co-located QTLs with additive effects were identified on chromosomes 2B, 3D, 4A, 6A, and 7B. The two major QTLs, ***-3B. 1 and ***-3B. 1, in cluster wPt666008-wPt5870 on chromosome 3B were detected in three different environments, which perhaps can be directly applied to improve the textural properties of noodles. These findings could offer evidence for the selection or development of new wheat varieties with noodle quality using molecular marker-assisted selection （MAS）.

We monitored 16 X-ray selected young solar-type stars for light variation and found appreciable periodic light variability with amplitudes of a few hundredths of a magni- tude in nine of the objects. Using the method of Phase Dispersion Minimization （PDM） and Fourier analysis （software PERIOD04）, the rotation periods of these stars were determined from the photometric data. The rotation periods of all nine stars are shorter than about 3 days. It is suggested that, as with the Pleiades cluster, small amplitude light variations are quite common among young solar-type stars with rotation periods around 3 days or less. This gives further evidence for the spin up of solar-type stars predicted by models of angular momentum evolution of pre-main sequence stars.

Toad venom, called as Chan Su in China, is a widely used traditional Chinese medicine(TCM) whose active components are mainly bufadienolides. Chan Su could exhibit cardiotonic, anti-microbial, anti-inflammatory and, most importantly, anti-cancer effects. In the present review, reports about the in vitro, in vivo and clinical anti-cancer effects of Chan Su or its representative component, bufalin, were ***, reported anti-cancer mechanisms of cardenolides, structure analogues of bufadienolides, were also introduced. Based on the results got from research of Chan Su/bufalin and the results from cardenolides, possible signal network related to the anti-cancer effects of Chan Su/bufalin was predicted. Furthermore, future potential use of Chan Su in anti-cancer therapy was discussed.

The wheatgrass, Thinopyrum intermedium （Host） Barkworth ＆ DR Dewey, shows many beneficial characteristics, such as big spikes and high resistance to many diseases. To transfer the beneficial genes of this species, many wheat- Thinopyrum intermedium alien chromosome lines were developed. Of them, Shannong 0095 （SN0095）, a disomic substitution, has long spikes and flag-leaves, and thus may be an important genetic resource for wheat yield improvement. In order to realize its heterosis and combining ability on major yield traits, a 7 ×7 complete diallel design was made according to Griffing＇s Method-1. The results showed that heterosis for spike length （SPL）, flag-leaf area （FLA）, number of spikes per plant （NSP）, number of spikelets per spike （NSL）, kernels per spike （KPS）, 1 000-kernel weight （TKW） and grain yield per plant （GYP） existed in all the crosses by SN0095, but heterobeltiosis occurred only for KPS, TKW, and GYP. The relative mid-parent heterosis （RMH） and relative high-parent heterosis （RHH） for GYP, which valued as high as 35.32 and 29.92% respectively, were the highest among all the traits mearsured. Though additive and non-additive gene effects and cytoplasmic effects （or cytoplasmic-nuclear interaction effects） were found in governing all the traits measured above, additive gene action played a predominant role. The results also showed that SN0095 was the best-general combiner for SPL and FLA, and high-general combiner for NSP amongst all the parents. Estimates of specific combining ability （SCA） showed that SN0095 could also make high-SCA combinations for GYP, such as SN0095 × Jimai 19 （JMI9）. SN0095 could be a unique and important parent in hybrid wheat breeding programs.

The lijiang 2.4-meter Telescope(LJT), the largest common-purpose optical telescope in China,has been available to the worldwide astronomical community since 2008. It is located at the Gaomeigu site,lijiang Observatory(LJO), in the southwest of China. The site has very good observational *** its 10-year operation, several instruments have been equipped on the LJT. Astronomers can perform both photometric and spectral observations. The main scientific goals of LJT include recording photometric and spectral evolution of supernovae, reverberation mapping of active galactic nuclei, investigating the physical properties of binary stars and near-earth objects(comets and asteroids), and identification of exoplanets and all kinds of transients. Until now, the masses of 41 high accretion rate black holes have been measured, and more than 168 supernovae have been identified by the LJT. More than 190 papers related to the LJT have been published. In this paper, the general observation conditions of the Gaomeigu site is introduced at first. Then, the structure of the LJT is described in detail, including the optical, mechanical, motion and control system. The specification of all the instruments and some detailed parameters of the YFOSC is also presented. Finally, some important scientific results and future expectations are summarized.

农业面源污染治理是推动我国农业低碳转型与绿色发展的关键环节。为深入分析高标准基本农田建设政策在农业面源污染减量中发挥的重要作用,该文尝试构建高标准基本农田建设政策影响农业面源污染的理论分析框架,并利用连续DID模型、中介效应模型予以实证检验。研究结果表明,高标准基本农田建设政策对农业面源污染具有持续的抑制效应,该结论在替换核心解释变量、安慰剂检验、排除其他政策干扰等稳健性检验后依然成立;异质性分析发现,在农业功能区维度,高标准基本农田建设政策的“减污”效应主要作用于粮食主产区,而在非粮食主产区不显著;在自然地理维度,政策实施的“减污”效果在东部和中部地区均显著,而在西部不明显;影响机制分析表明,高标准基本农田建设政策可以通过改善土地质量、提高农业经营规模效率的双重渠道来抑制农业面源污染。据此,通过持续释放高标准基本农田建设的政策红利、引导土地规模化经营、加快农业绿色技术推广等举措,统筹推进“减污”与“增产”两大战略目标,进而实现我国农业的可持续发展。

生态文明建设是国家治理体系的重要内容,是国家治理能力现代化的重要体现。生态文明建设从社会建设中的“嵌入式”表达到融入宪法后成为一个独立建设的领域,有着划时代的历史意义。然而实践中,生态文明建设依然面临着区域发展、资源配置和公众参与三方面均不协调的现实挑战,这严重制约着生态文明建设的法治化进程。生态文明建设目标确立之后,我国尚需制定专门的《生态文明建设促进法》,亟需对经济社会发展中的资源消耗同步构建完善的补偿制度。基于生态文明建设的现状,必须树立生态法治的思维观念,构建完整的生态补偿法律体系,将生态文明建设纳入法治化轨道,充分将政府、市场、公众三者在生态文明建设中的权利义务相融合,才能够真正实现生态文明建设的法治化。
