Hyperlipidemia is a frequent metabolic disorder that is closely associated with diet. It is believed that brown rice, containing the outer bran layer and germ, is beneficial for the remission of hyperlipidemia. This study established a rat model of hyperlipidemia by feeding a high-fat diet. The hypolipidemic potential of germinated brown rice(gbrown) and germinated black rice(a germinated black-pigmented brown rice, gblack) were explored in the model rats, mainly in the aspects of blood lipids, lipases, apolipoproteins, and inflammation. The gut microbiota in hyperlipidemic rats receiving diverse dietary interventions was determined by 16S rDNA sequencing. The results showed that the intervention of gbrown/gblack alleviated the hyperlipidemia in rats, evidenced by decreased TC, Tg, LDL-C, and apolipoprotein b, and increased HDL-C, HL, LPL, LCAT, and apolipoprotein A1. gbrown/gblack also weakened the inflammation in hyperlipidemia rats, evidenced by decreased TNF-α, IL-6, and ET-1. In addition, 16S rDNA sequencing revealed that the diet of gbrown/gblack elevated the abundance and diversity of gut microbiota in hyperlipidemia rats. At the phylum level, gbrown/gblack decreased Firmicutes, increased bacteroidetes, and decreased the F/b ratio in hyperlipidemia rats. At the genus level, gbrown/gblack decreased Streptococcus and increased Ruminococcus and Allobaculum in hyperlipidemia rats. Some differential microbial genera relating to lipid metabolism were also determined, such as the Lachnospira and Ruminococcus in the gblack group, and the Phascolarctobacterium, Dorea, Turicibacter, and Escherichia-Shigella in the gbrown group. Notably, the beneficial effect of gblack was stronger than gbrown. To sum up, the dietary interventions of gbrown/gblack contributed to the remission of hyperlipidemia by alleviating the dysbiosis of gut microbiota.

Vigorously developing agricultural circular economy is an effective way to achieve sustainable agricultural development,and a strategic measure to ease the pressure on agricultural resources,protect ecological and clean resources,and promote sustainable agricultural and rural economic development. From the theoretical perspective of circular agriculture,this paper builds the evaluation indicator system for circular agriculture,and uses entropy method to carry out the comprehensive evaluation of the development level of agricultural circular economy in guizhou Province from 2003 to 2012. At the same time,this paper analyzes the obstacles to the development of agricultural circular economy in guizhou Province in 2012,and sets forth the relevant recommendations based on these limitations,in order to improve the development level of circular agriculture in guizhou Province.

With rapid economic development,resource and environment problems become more and more prominent. Chongqing Municipality, as a city focusing on industrial development in the past,has serious problem of environmental pollution and scarce agricultural resources. At present,it is urgent to find out how to develop circular agriculture and coordinate economic,social,environmental development. On the basis of understanding the intension of circular agriculture,this paper built evaluation indicator system for development of circular agriculture from social and economic development,resource reduction input,resource recycling use,and resource and environment safety. Then,it made an evaluation of circular agricultural development of Chongqing Municipality by AHP approach combined with gray correlation analysis. Finally,it came up with countermeasures,including reducing input of agricultural production materials,strengthening land management,promoting scientific and technological progress,and improving policy systems.

当前,世界范围内正面临着粮食增产与维护和改善农业生态环境质量的挑战,治理面源污染是其中的重要内容。通过对英国面源污染治理的防治技术、技术推广体系和相关政策措施方面的系统整理和分析,就我国相应工作提出建议和对策。结合我国当前一控两减三基本的农业资源和环境对策,今后应主要通过源头控制和过程拦截两种手段,注重化肥的减量优化以及有机无机配合使用,强调土地利用管理、农业结构调整以及种养结合,开发和实施符合各地实际情况的面源污染防控技术和措施。发挥非政府形式技术服务体系在面源污染防控中的重要作用,利用政府补贴、生态补偿等经济手段鼓励农户和农业企业主动防控氮磷物质的损失和对水土系统的污染。相关技术文件和规定应更加具体、明确、具有更好的操作性,依托现代信息手段等进行面源污染数据的收集、传输和分析,并在政策制定过程中统筹考虑。将面源污染纳入国家经济和社会发展的总体规划,与产业优化、经济发展指标完善等宏观政策统一,逐步提升生态文明的建设质量,促进我国社会和经济的可持续发展。

Drought stress impairs plant growth and other physiological functions. MeHDZ14, a homeodomainleucine zipper I transcription factor, is strongly induced by drought stress in various cassava ***, the role of MeHDZ14 in cassava growth regulation has remained unclear. Here we report that MeHDZ14 affected plant height, such that a dwarf phenotype and altered internode elongation were observed in transgenic cassava lines. MeHDZ14 was found to negatively regulate the biosynthesis of lignin. Its overexpression resulted in abaxially rolled leaves. The morphogenesis of leaf epidermal cells was inhibited by overexpression of MeHDZ14, with decreased auxin and gibberellin and increased cytokinin contents. MeHDZ14 was found to regulate many drought-responsive genes, including genes involved in cell wall synthesis and expansion. MeHDZ14 bound to the promoter of caffeic acid 3-Omethyltransferase 1(MeCOMT1), acting as a transcriptional repressor of genes involved in cell wall development. MeHDZ14 appears to act as a negative regulator of internode elongation and epidermal cell morphogenesis during cassava leaf development.
