The paper analyzed the seasonal variation of the concentrations of Cr, Mn, Al, N, P, As, Ba, Ca, Cu, Fe, Mg, and K in South Lake Cyohoha water using spectroscopic technique. Water samples were taken monthly at Ngenda, Karehe and Nyamabuye stations from January 2009 to December 2010. The results showed that the concentrations of aluminum, nitrogen, potassium, arsenic, phosphorous, manganese, chromium,...
Myostatin (MSTN) is a negative regulator of skeletal muscle growth, in order to study the effect of inhibition MSTN expression on the proliferation of bovine skeletal muscle satellite cells, we constructed co-expression vector pcDNA3.1-Pro-MSTNshRNA, transfected it into muscle satellite cells by Liposome 2000, and detected cell proliferation changes by CCK-8 method and flow cytometry after 48 h. The...
There are a total of more than 40 reported maize viral diseases worldwide. Five of them have reportedly occurred in China. They are maize rough dwarf disease, maize dwarf mosaic disease, maize streak dwarf disease, maize crimson leaf disease, maize wallaby ear disease and corn lethal necrosis disease. This paper reviewed their occurrence and distribution as well as virus identification techniques...
Root C and root-released C are closely related to soil organic matter content and mechanistic simulation modeling has proven to be useful for studying root and soil organic C dynamics in plant-soil ecosystems. A computer model was designed in this study to simulate the dynamics of root C and root released C decomposition in situ and the dynamics of different forms of C in soil under two barley cultivars...
The full-length Mlo gene was obtained by reverse transcription polymerase chain reaction (RT-PCR) and RACE. The result of sequence analysis indicated that Mlo gene from Pericallis hybrida B. Nord. contained about 1 296 bp open reading frame and encoded 431 amino acids. According to the comparison of the exogenous gene sequences by BLAST analysis and phylogenetic analysis, Mlo gene shared over 85%...
In order to study the gene sequence of Min pig Y-box binding protein (YB-1) gene, the complete coding sequence of Min pig YB-1 gene was cloned by RT-PCR, the sequence features were analyzed by some software and online website. The results showed that the complete CDS of Min pig Y-box was found to be 975 bp long, encoding 324 amino acids. It contained a conserved cold shock domain and several phosphorylation...
For the first time, we used Tullgren method made a study on vertical migrating and cluster analysis of the soil mesofauna in Dongying Halophytes Garden in the Yellow River Delta (YRD), Shandong Province. The results showed that the soil mesofauna tended to gather on soil surface in most samples at most times, but the vertical migrating greatly varied in different seasons or environment conditions...
microRNAs (miRNAs) play important regulatory roles in eukaryotic gene expression, predominantly at the posttranscriptional level. Elaborate and diverse biogenesis pathways have evolved to produce miRNAs. miRNA biogenesis is a multistep process including transcription, precursor slicing, methylation, nuclear export, and RNA-induced silencing complex assembly. In the decade, since the first discovery...
Propamocarb (PM) residue in cucumber (Cucumis sativus L.) receives little attention. As is well known to all, high PM residue of cucumber could lead to increase in the violation rates of maximum residue limits and ultimately cause harm to human health. Knowledge of PM residue could help cucumber breeders in developing cultivars with low PM residue and improving cucumber quality. In this study, 32...
Methionine (Met) and lysine (Lys) have been reported as the first two limiting amino acids (AA) for maximum milk yield and milk protein production. Supplying these AA may improve microbial protein synthesis and therefore improve milk production without adding excess N to the environment. This observation utilized fermented soybean meal (SBM), cottonseed meal (CSM), rapeseed meal (RSM) and corn by...
miRNA can regulate development and milk yield of the mammary gland through epigenetic mechanism. miRNA can directly and indirectly modulate the activity of the epigenetic machinery, target genes through post-inhibition of translation initiation, mediate miRNA decay, target genes and inhibit the positive regulation, regulate tone modification, and regulate DNA methylation of target genes. Here we reviewed...
This paper contributed to the pool of studies about agricultural surplus labor in China, also acted as the root to the imminent settlement of the issues concerning agriculture, countryside and farmers. Using data from survey of agricultural surplus labor in 2012, which covered three provinces in northern, midwestern and southern parts of China, this paper analyzed the influential factors on agricultural...
An experiment was carried out to assess the phosphorus status of free grazing goats at Faisalabad, Pakistan. Samples were collected fortnightly during summer and winter seasons of 2010 from soil and plants. The highest (118±0.54 mg • kg −1 ) levels of feces phosphorus were recorded in lactating goats during winter and (9.87±0.99 mg • kg −1 ) in urine of male during winter. Similarly...
Hapten sulfaguanidine (SG) was coupled with carrier protein bovine serum albumin (BSA) to form a full antigen SG-BSA by diazotization and glutaraldehyde methods. Ovalbumin (OVA) was used as protein carrier to couple with Hapten SG by glutaraldehyde method. Then, the immunogen and the coating antigen were purified by dialysis and gel exclusion chromatography. The conjugated ratio of SG to BSA in artificial...
Dwarfism is one of the most important traits in crop breeding. In this study, a dwarf cucumber D0462 and a vine NA129 were taken as experimental materials. The metabolism of hydrogen peroxide (H 2 O 2 ) and superoxide anion radical (O 2− •), activities of antioxidant enzymes, and the levels of endogenous hormones of the two cultivars were compared. In the whole growth...
Solving the financing problem in rural areas and improving the level of economic development in rural areas become important guarantees for the expansion of domestic demand. This research, through studying the current situation of rural financing, pointed out the main factors restricting the financing in rural areas, such as high risk credit, slow income growth, high financing cost and difficult mortgage...
In order to establish the system of high frequency plant regeneration for japonica rice mature embryos, the effects of different concentrations of CuSO 4 and uniconazole on in vitro culture of mature embryos were studied using three rice cultivars of Kongyu 131, Longjing 24, and Dongnong 425 as test materials. The results showed that callus induction and differentiation of japonica rice mature...
The objective of the paper was to detect HSP72 expression and HSP72 gene sequence in heat shocked mouse preimplantation embryos and the effects of different thermo conditions on hatching rates of embryos. The mouse blastocysts cultured in vitro were heat treated at 40°C and 38°C for 1 h, 2 h and 3 h and then recovered at 37°C for 3 h, 2 h and 1 h, respectively, to detect their HSP72 gene expression...
Farmers as the largest population group in China, their integrity levels impact the process of socialist modernization and construction of socialist harmonious society directly. Farmers’ credit construction is an important part of the construction of new socialist countryside. As the subject of construction of new socialist countryside, some farmers are weak in credit awareness. Low credibility of...
The study was conducted to demonstrate the effects of dietary protein and water temperature on growth and flesh quality of Songpu mirror carp (Cyprinus carpio) at an initial weight (165.24±5.08) g. Practical diets were formulated to contain five protein levels (29.12%, 31.46%, 34.49%, 38.17%, and 40.13%), and each diet was randomly assigned triplicate groups of 15 fishes at three temperatures (18°C,...
