Small ubiquitin-like modifier(SUMO)E3 ligases that facilitate the conjugation of SUMO proteins to target substrates contain an SP-RING domain which is like the RING domain found in ubiquitin E3 *** this study,we isolated and characterized the Oryza sativa protein inhibitor of activated STAT like1(OsPIAL1)containing SP-RING domains,as the rice homolog of Arabidopsis ***1 interacts with OsSUMO proteins but does not interact with rice SUMO-conjugating enzymes(OsSCEs).An analysis of transgenic rice plant shows that OsPIAL1 is involved in SUMO conjugation to SCEs but not in SUMO conjugation to *** addition,this OsPIAL1 activity requires drought stress *** profiles show that the OsPIAL1 gene is induced by only drought stress in the leaves,whereas it is repressed by ABA and abiotic stresses in the *** stress leads to the fastest decrease in OsPIAL1 transcripts in the ***,the stress experiments indicate that the transgenic rice plants overexpressing OsPIAL1 exhibit a drought stress-tolerant phenotype but a salt stress hypersensitive *** results and those from Arabidopsis pial mutants suggest that PIALs act as a positive regulator in the drought stress response but as a negative regulator in the salt stress response.

This paper is concerned with a nonlocal hyperbolic system as follows utt = △u ＋（∫Ωvdx ）^p for x∈R^N,t〉0 ,utt = △u ＋（∫Ωvdx ）^q for x∈R^N,t〉0 ,u（x,0）=u0（x）,ut（x,0）=u01（x） for x∈R^N,u（x,0）=u0（x）,ut（x,0）=u01（x） for x∈R^N, where 1≤ N ≤3, p ≥1, q ≥ 1 and pq 〉 1. Here the initial values are compactly supported and Ω belong to R^N is a bounded open region. The blow-up curve, blow-up rate and profile of the solution are discussed.

We study the minimizers of the Ginzburg-Landau model for variable thickness, superconducting, thin films with high k, placed in an applied magnetic field hex, when hex is of the order of the ＂first critical field＂, i.e. of the order of ｜lnε｜. We obtain the asymptotic estimates of minimal energy and describe the possible locations of the vortices.

The feasibility of community-based bioassessment of environmental quality status was studied using microphytobenthos（MPB） in estuarine intertidal *** sediment samples of MPB were collected monthly during a 1-year cycle（September 2006-August 2007） at four sampling stations in the Nakdong River Estuary,*** variables,such as salinity,radiation,grain size of sediment,Si（OH）4（Si）,nitrate（NO3^-）,nitrite（NO2^-）,ammonium（NH4~＋） and phosphates（PO4^（3-））,were measured synchronously for comparison with biotic *** statistical analyses were carried out for assessment the relationship between biotic and environmental *** results showed that：（1） the MPB community structures were significant differences among four sampling stations;（2） spatial variation in the MPB communities were significantly correlated with environmental variables,especially the nutrient NH4＋ in combination with salinity and grain size;（3） three species（Navicula lacustris,Pleurosigma anglulatum and Fragilaria sp.1） were significantly correlated with nutrients and/or Si;and（4） the species richness and diversity were significantly correlated with the grain *** is suggested that MPB communities may be used as a potentially robust bioindicator for assessing environmental quality status in estuarine intertidal ecosystems.

Lattice preferred orientations (LPO) of plagioclase and augite are measured on layered gabbro from the Panxi region, Sichuan Province. The LPO concentration [010] of plagioclase and [100] of augite are perpendicular to the foliation, which indicates a kind of growth fabric associated with crystallizing habits of minerals when the magma is solidifying under the compaction. Calculated seismic velocities based on LPO data of minerals give rise to rather strong anisotropy 5.81% and 5.54% for compressional seismic wave (Vp) and shear seismic wave (Vs), respectively. The experiments at high temperature and high pressure show that the P-wave velocity of layered gabbro is 6.44-6.97 km/s with the maximum Vp anisotropy 5.22% and the Poisson's ratio is between 0.28-0.31. According to the comparison of fabrics with seismic velocities of layered gabbro, it is uggested that the large-scale layered intrusive body or the similar layered geological body may exist in the lower crust of this area. Such a layered intrusive body which has strong seismic anisotropy may be the seismic reflector in the lower crust.

韩国木质文物的系统保护始于1976年新安沉船出土后,新安沉船保护方法的研究促进了饱水木保护技术的发展,是韩国木质文物保护的转折点,为木质文物保护新方法、新技术的研究搭建了一个平台。二十世纪九十年代以后韩国出土了大量木质文物,这些文物的出土提供了很多新信息,是重要的历史资源。这一趋势促使了韩国保护工作人员对木质文物保护新方的研究。韩国的木质文物实际上是埋藏在沼泽、湖底和海底的饱水木,这些环境限制了微生物的生长。遗址中出土的木质器物是糟朽木或是碳化木。因此,韩国木质文物的保护分两类:一类是用传统工艺修复木建筑和漆器,另一类是保护处理饱水木器。文中介绍了韩国文物保护实验室保护修复木质文物的几个实例。
