This study shows that minor amount of water plays a very important role in solvent-free hydrogenation of halogenated nitrobenzenes. For dried sponge Pd, the reaction cannot occur in the absence of water. For Pd/C catalyst, minor amount of water reduces the induction time, increases the reaction rate and reaction TOFs. Water might enhance the diffusion, adsorption and dissociation of H2 on Pd catalysts.

WRKY transcription factors are involved in the regulation of response to biotic and abiotic stresses in plants. A full-length cDNA clone of rice WRKY82 gene （OsWRKY82） was isolated from a cDNA library generated from leaves infected by Magnaporthe grisea. OsWRKY82 contained an entire open reading frame in length of 1 701 bp, and was predicted to encode a polypeptide of 566 amino acid residues consisting of two WRKY domains, each with a zinc finger motif of C2H2, belonging to the WRKY subgroup I. OsWRKY82 shared high identity at the amino acid level with those from Sorghum bicolor, Hordeum vulgare, and Zea mays. The transcript level of OsWRKY82 was relatively higher in stems, leaves, and flowers, and less abundant in grains. It was induced by inoculation with M. grisea and Rhizoctonia solani. However, the inducible expression in incompatible rice-M. grisea interactions was earlier and greater than that in compatible interactions. The expression of OsWRKY82 was up-regulated by methyl jasmonate and ethephon, whereas salicylic acid exerted no effects on its expression. Moreover, OsWRKY82 exhibited transcriptional activation ability in yeast. Additionally, OsWRKY82 transcripts could be induced by wounding and heat shocking, but not by abscisic acid, cold, high salinity and dehydration. By contrast, gibberellin suppressed the expression of OsWRKY82. These indicate that OsWRKY82 is a multiply stress-inducible gene responding to both biotic and abiotic stresses, and may be involved in the regulation of defense response to pathogens and tolerance against abiotic stresses by jasmonic acid/ethylene-dependent signaling pathway.

根据2010年8月至2014年8月对浙江渔山列岛附近海域6个站位的大型底栖动物调查,分析了渔山列岛附近海域大型底栖动物的群落结构特征,包括群落物种组成、优势种、丰度、生物量、群落的时空变化等,分析了大型底栖动物的群落结构,并使用AMBI和M-AMBI对大型底栖动物群落和环境质量进行了评估。结果表明:本次调查共鉴定出大型底栖动物60种,其中多毛类动物25种,软体动物13种,甲壳动物9种,棘皮动物4种,鱼类6种,其它动物3种(包括纽虫2种和扁形动物1种)。多毛类动物是该研究海域大型底栖动物群落的主要成分,占据了群落总种数的41.67%。在5个调查年份中,共出现了17种优势种,优势种年际变化很大,在5年内多次出现的优势种只有5种。在物种丰度方面,多毛类仍然是群落丰度的主要贡献者,但丰度的年际变化明显,从7.07%到40.89%不等。鱼类在生物量方面的重要性最高,主要是红狼牙鰕虎鱼Odontamblyopus rubicundus的多次出现所致。在环境因子中,悬浮物和盐度被证明是该海域对大型底栖动物群落影响最大的环境因子,这与该海域较高的悬浮物含量以及多变的盐度密切相关;在AMBI和M-AMBI进行的生态质量评价显示,该海域多数站位的生态质量状况较好,处于轻度扰动的影响之下,这些扰动来源于环境和底质状况不稳定引发的自然扰动而非人为污染。
