The author investigated the antioxidant effect of irbesartan[2-butyl-3-（{4-[2-（2H-l,2,3,4-tetrazol-5-yl）. phenyl]phenyl}methyl）-1,3-diazaspiro[4.4]non-1-en-4-one], an angiotensin receptor blocker（ARB）, on the oxidation of erythrocytes induced by 2,2-[azobis（2-amidinopropane） hydrochloride]（AAPH） and H2O2 The value of half concentration（IC50） of irbesartan to scavenge radicals was measured by reacting it with 2,2-[azinobis（3-ethylbenzothia- zoline-6-sulfonate） radical eation]（ABTS＋）. Activities of the catalase（CAT）, superoxide dismutase（SOD）, glutathione peroxidase（GSH-Px） and the content of malondialdehyde（MDA） in liver tissue and blood serum of normal-rats were measured by means of speetrophotometry to study the antioxidation function of irbesartan. Results of experiments show that irbesartan can scavenge ABTS＋ and superoxide radicals effectively as well as inhibit AAPH-, H2O2-induced hemolysis of erythrocytes. Irbesartan can also increase the activities of GSH-Px, SOD, CAT and decrease the content of MDA of normal rats. So irbesartan is a good antioxidant.

Sucrose non-fermenting 1-related protein kinase 2(Sn RK2) is a plant-specific serine/threonine kinase involved in response to adverse environmental stimuli. Previous studies showed that Ta Sn RK2.4 was involved in response to abiotic stresses and conferred enhanced tolerance to multiple stresses in Arabidopsis. Further experiments were performed to decipher the underlying mechanisms and discover new functions. The genomic sequences of Ta Sn RK2.4 s locating on chromosome 3 A, 3 B and 3 D were obtained. Sequencing identified one and 13 variations of Ta Sn RK2.4-3 A and Ta Sn RK2.4-3 B, respectively, but no variation was detected in Ta Sn RK2.4-3 D. The markers 2.4 AM1, 2.4 BM1 and 2.4 BM2 were developed based on three variations. Association analysis showed that both Ta Sn RK2.4-3 A and Ta Sn RK2.4-3 B were significantly associated with thousand-kernel weight(TKW), and that SNP3 A-T and SNP3 B-C were favorable alleles for higher TKW. Yeast two-hybrid and split luciferase assays showed that Ta Sn RK2.4 physically interacted with abiotic stress responsive protein Ta LTP3, suggesting that Ta Sn RK2.4 enhanced abiotic stress tolerance by activating Ta LTP3. Our studies suggested that Ta Sn RK2.4 have potential in improving TKW and response to abiotic stress.

A pot experiment was conducted in artificially Cd-contaminated （5 mg Cd kg 1） soils to investigate the feasibility of using lime （3 g kg-1） or phosphate （80 mg P kg-1） to mitigate uptake of Cd by vegetables. Five common vegetables in South China, including lettuce （Lactuca sativa L. var. ramosa Hort.）, Chinese cabbage [Brassica rapa L. subsp. Chinensis （L.） var. parachinensis （L. H. Bailey） Hanect], Chinese broccoli （Brassica oleracea L. vat. albiflora Kuntze）, white amaranth （Amaranthus tricolor L.） and purslane （Amaranthus viridis L.）, were grown in the soils and harvested after 60 d. The results showed that liming significantly reduced Cd uptake by most vegetables by 40%-50% （or a maximum of 70%）, mainly due to immobilization of soil Cd. Increased availability of Ca in the soil might also contribute to the Cd uptake reduction as a result of absorption competition between Ca and Cd. liming caused biomass reduction in white amaranth and purslane, but did not influence growth of the other vegetables. Phosphate decreased Cd uptake by vegetables by 12% 23%. Compared with lime, phosphate decreased, to a smaller extent, the bioavailability of Cd in most cases. Phosphate markedly promoted growth of vegetables. Changes in soil chemistry by adding lime or phosphate did not markedly influence nutrient uptake of vegetables except that lime increased Ca content and phosphate increased P content in shoots of the vegetables. The results suggested that a proper application of lime could be effective in reducing Cd uptake of vegetables, and phosphate could promote growth of the vegetables as well as alleviate the toxicity of Cd.

Developing a low-cost and well-recyclable adsorbent with high adsorption capacity is greatly desirable in dye wastewater treatment. Here, we demonstrate a kind of novel tough and reusable hydrogel beads with quite high capacity of dye adsorption via incorporating mussel-bioinspired poly（L-DOPA）（PDOPA） into alginate/poly（acrylamide） double network （DN） hydrogels. The synthesized PDOPA nanoaggregates were introduced into the DN hydrogels by simple one-pot mixing with the monomers prior to polymerization. The fabricated hydrogel beads exhibited high mechanical strength and good elastic recovery due to the interpenetrating Ca2＋-alginate and poly（acrylamide） networks. It was shown that the beads exhibited relatively high dye adsorption capacity compared to other adsorbents reported in literature, and the introduction of PDOPA with an appropriate amount raised the adsorption capacity. It is believed that the addition of PDOPA and the matrix of double network architecture contributed synergistically to the high adsorption capacity of hydrogel beads. Moreover, the desorption of dyes could be easily realized via rinsing in acidic water and ethanol solution. The hydrogel beads remained the high adsorption capacity even after 5 times of adsorption and desorption cycles. This tough and stable hydrogel with high adsorption capacity may have potential in treatment of dye wastewater released by textile dyeing industry.

Plant peptide hormones play important roles in plant growth and development. Among these hormones, the C-TERMINALLYENCODED PEPTIDE（CEP） belongs to a newly found peptide family that regulates root development in Arabidopsis as well as in other species. However, nothing is known about the CEP genes in apple（Malus×domestica, MdCEP）. In this study, a total of 27 apple CEP genes were identified through a genome-wide analysis and were phylogenetically divided into three classes（Ⅰ, Ⅱ and Ⅲ）. The predicted MdCEP genes were distributed across 10 of 17 chromosomes with different densities. Next, the gene structures and motif compositions of the MdCEP genes were analyzed. Subsequently, the expression analysis suggested that the MdCEP genes were highly activated in roots and that MdCEP23 may play an important role in regulating the growth and development of roots. Moreover, all of the MdCEP genes were responsive to multiple abiotic stresses, indicating that MdCEP genes may be involved with various aspects of physiological processes in apple. Nearly one-third of MdCEP genes had a significant response to low nitrogen treatment. Most of the MdCEP genes were up-regulated under stress, including mannitol, polyethylene glycol（PEG） and abscisic acid（ABA）, suggesting that MdCEP genes may be involved in the drought stress response. This study provides insight into the putative functions of the MdCEP genes using a genome-wide analysis of the CEP gene family.

As one of the key parameters for characterizing crop canopy structure, Leaf Area Index(LAI) has great significance in monitoring the crop growth and estimating the yield. However, due to the nonlinearity and spatial heterogeneity of LAI inversion model, there exists scale error in LAI inversion result, which limits the application of LAI product from different remote sensing data. Therefore, it is necessary to conduct studies on scale effect. This study was based on the Heihe Oasis, Zhangye city, Gansu province, China and the following works were carried out: Airborne hyperspectral CASI(Compact Airborne Spectrographic Imager) image and LAI statistic models were adopted in muti-scale LAI inversion. The overall difference of muti-scale LAI inversion was analyzed in an all-round way. This was based on two aspects, "first inversion and then integration" and "first integration and then inversion", and on scale difference characteristics of three scale transformation methods. The generation mechanism of scale effect was refined, and the optimal LAI inversion model was expanded by Taylor expansion. By doing so, it quantitatively analyzed the contribution of various inversion processes to scale effect. It was found that the cubic polynomial regression model based on NDVI(940.7 nm, 712 nm) was the optimal model, where its coefficient of determination R2 and the correlation coefficient of test samples R reached 0.72 and 0.936, respectively. Combined with Taylor expansion, it analyzed the scale error generated by LAI inversion model. After the scale effect correction of one-dimensional and twodimensional variables, the correlation coefficient of CCD-LAI(China Environment Satellite HJ/CCD images) and CASI-LAI products(Compact Airborne Spectro graphic Imager products) increased from 0.793 to 0.875 and 0.901, respectively. The mean value, standard deviation, and relative true value of the two went consistent. Compared with onedimensional variable correction method, the twodimensi
