The Pomacea canaliculata, also known as apple snail, is an invasive species in China, posing a serious threat to agricultural production and public health. To prevent its rampant infestation, we developed a highly efficient snail-killing lead compound, 1-(4-chlorophenyl)-3-(pyridin-3-yl)urea (PBQ). However, the killing mechanism of PBQ remains unclear. To elucidate this, two novel compounds, B-PBQ and J-PBQ, were developed through structural modification of PBQ and were used, through both protein pull-down assay and confocal laser scanning microscopy imaging, to identify and confirm that phosphofructokinase(PFK) in the apple snail is the primary target protein of PBQ. Further studies revealed that PBQ successfully inhibits the activity,content, and expression of PFK in apple snail, disrupting the glycolysis pathway and leading to abnormal energy *** disruptions impair the snail’s tolerance to low oxygen, resulting in its efficient eradication. These findings offer a promising direction for developing next-generation PFK-targeted snail-killing pesticides. Furthermore, the strategy of combining pull-down assays with optical imaging used in this work provides a novel approach for the exploration of mechanisms of other pesticide candidates.

Journal of Integrative Agriculture 2014年第10期13卷 2236-2242页

The biological chemistry would be responsible for the meat quality. This study tried to investigate the transcript expression profile and explain the characteristics of differentially expressed genes between the Wujin and Landrace pigs. The results showed that 526 differentially expressed genes were found by comparing the transcript expression profile of muscle tissue between Wujin and Landrace pigs. Among them, 335 genes showed up-regulations and 191 genes showed down-regulations in Wujin pigs compared with the Landrace pigs. Gene ontology （GO） analysis indicated that the differentially expressed genes were clustered into three groups involving in protein synthesis, energy metabolism and immune response. Kyoto encyclopedia of genes and genomes （KEGG） pathway analysis found that these differentially expressed genes participated in protein synthesis metabolism, energy metabolism and immune response pathway. The Database for Annotation, Visualization and Integrated Discovery （DAVID） analysis of protein function and protein domains function also confirmed that differentially expressed genes belonged to protein synthesis, energy metabolism and immune response. Genes related protein synthesis metabolism pathway in Landrace was higher than in Wujin pigs. However, differentially expressed genes related energy metabolism and immune response was up-regulated in Wujin pigs compared with Landrace pigs. Quantitative real-time RT-PCR on selected genes was used to confirm the results from the microarray. These suggested that the genes related to protein synthesis, energy metabolism and immune response would contribute to the growth performance, meat quality as well as anti-disease capacity.

ETI： an efficient index for set similarity queries

引用

Frontiers of Computer science 2012年第6期6卷 700-712页

作者： Lianyin JIA Jianqing XI Mengjuan LI Yong LIU Decheng MIAO School of Computer science&Engineering South China University of TechnologyGuangzhou 530641China department of Computer science Yunnan Agricultural UniversityKunming 650201China Library Yunnan Normal UniversityKunming 650092China

Set queries are an important topic and have attracted a lot of attention. Earlier research mainly concentrated on set containment queries. In this paper we focus on the T-Overlap query which is the foundation of the set similarity query. To address this issue, unlike traditional algorithms that are based on an inverted index, we design a new paradigm based on the prefix tree （trie） called the expanded trie index （ETI） which expands the trie node structure by adding some new properties. Based on ETI, we convert the T- Overlap problem to finding query nodes with specific query depth equaling to T and propose a new algorithm called T- Similarity to solve T-Overlap efficiently. Then we carry out a three-step framework to extend T-Overlap to other simi- larity predicates. Extensive experiments are carried out to compare T-Similarity with other inverted index based algorithms from cardinality of query, overlap threshold, dataset size, the number of distinct elements and so on. Results show that T-Similarity outperforms the state-of-the-art algorithms in many aspects.

Phenolic compounds constitute one of the major pollutants in the modern world. Although many physical and chemical treatment technologies for their removal exist, most of them are economically not feasible. The present study was aimed at using silk cotton hull, a potent agricultural waste as an adsobent for removal of 2,4-dichlorophenol (2,4-DCP), which was used as a model phenolic compound. The process parameters were investigated and optimized conditions were determined. The equilibrium time was found to ...

Twenty castrated male goats, each of Yun-Ling Black goats （YLB goat）, N × YLB hybrid goats （Nubian ♂ ×Yun-Ling Black goats 9） and B × YLB hybrid goats （Boer ♂× Yun-Ling Black goats ♀）, were used to evaluate the effect of crossbreeding on the meat chemical composition in the YLB goats of China. After weaning of 90 days, all the experimental goats were reared on natural pasture when they were slaughtered at an age of 730 days. The longissimus dorsi （LD） and biceps femoris （BF） muscles were sampled from each carcass to determine chemical compositions. Both hybrid goats had higher protein content （P 〈 0.01） and lower fat content （P 〈 0.05） than the YLB goats in the two types of muscle. The inosinic acid contents of LD muscle for the YLB goats and the B × YLB hybrid goats were significantly higher （P 〈 0.05） than that for the N × YLB hybrid goats. The LD muscle from the YLB goats contained higher essential amino acid （P 〈 0.01）, total amino acid （P 〈 0.01）, and some individual amino acid （P 〈 0.05） than those from the hybrid goats. The concentration of unsaturated fatty acid （USFA） of LD muscle from the N × YLB hybrid goats was significantly higher than the other two goat breeds （P〈0.05） but did not differ between the other two goat breeds （P〉0.05）. The YLB goats had significantly higher （P〈0.05） concentrations of oleic acid （C18：1） and linolenic acid （C18：3） of LD muscle than the hybrid goats, had significantly higher （P 〈 0.05） proportion of mono-unsaturated （Sum for C 16：1 and C 18：1） than the B ×YLB hybrid goats, and tended to be higher than the N × YLB hybrid goats （P 〉 0.05）. In contrast, the proportion of poly-unsaturated in the YLB goats was significantly lower （P 〈 0.05） than that in the hybrid goats.
