According to our previous study, saprophytic fungi Botrytis cinerea contained 579 predicted secretary proteins. Among them, we found that 122 of these proteins contained the highly conserved pathogenic-related host-targeting-motif RxLx within 100 residues adjacent to the signal peptide cleavage site. According to PEDNAT and COG of the GenBank database, the functions of this motif containing proteins...
Traditional studies on potential yield mainly referred to attainable yield: the maximum yield which could be reached by a crop in a given environment. The new concept of crop yield under average climate conditions was defined in this paper, which was affected by advancement of science and technology. Based on the new concept of crop yield, the time series techniques relying on past yield data was...
As a kind of brand-new technology, radio frequency identification (RFID) plays an important role in dairy information management, data control and acquisition. This paper introduced food safety tracing and culture function extension of managing system construction, analyzed the advantages and problems in dairy modern breeding technology, and finally put forward some suggestions for solution according...
The overwintering survival ratio of the cultivar Dongnongdongmai 1 with strong cold-resistance in paramos of Heilongjiang Province in China are over 85%. The tillering nodes are the most important organs for overwintering survival of winter wheat, because there are more substances associated with cold resistance in tillering nodes than those in leaves and roots. Proteins in the tillering nodes of...
Saponaria officinalis L. seeds were treated with different concentrations of chemical mutagen to determine the impact of media with various hormone concentrations on the induction of mutated (Saponaria officinalis L.) seeds' adventitious buds and rooting culture by using tissue culture technology. The results indicated that the optimum concentration of the chemical mutagen-EMS was 0.3%; the optimum...
Feeding rhythm of common carp was investigated from 4°cC to 34°C. The results indicated that there was a diel feeding rhythm for both adult (630–850 g) and youth (61–91 g) at all tested temperatures. There were two main activity peaks at 8:00–11:00 a.m. and 19:00–23:00 p.m., during which feeding quantities were 10.68%–32.53% and 16.25%–33.41% of the daily intake, respectively. When water temperature...
A total of 151 infant formula powder samples were tested for the screening of the Enterobacteriaceae bacteria, and it had been contaminated by the conditioned pathogen like Enterobacter sakazakii, Klebsiella pneumoniae, Klebsiella oxytoca, and Enterobacter cloacae. The results showed that six samples were separated Enterobacter sakazakii, 24 samples were separated Enterobacteriaceae by using the traditional...
Heilongjiang Province is an important marketable grain depot in China. Since the reform and opening up, Heilongjiang Province production capacity of foodstuff is increasingly growing into a new level. This paper started with the actuality of Heilongjiang Province integrated production capacity of foodstuff, and analyzed its major factors empirically through the mathematical model, then proposed some...
Wheat is Canada's the largest crop with most of the production in the western Canadian Prairie Provinces of Manitoba, Saskatchewan and Alberta. There were approximately 10 million (M) hectares (hm 2 ) seeded to wheat in Canada, including 7 M hm 2 of hexaploid spring wheat (Triticum aestivum L.), 2 M hm 2 of durum wheat (T. turgidum L. ssp. durum (Desf.) Husn.), and 1 M hm ...
A totatl of 116 isolates of rice blast fungus, Magnaporthe oryzae, were collected from 45 samples in different counties of Heilongjiang Province, and 20 Chinese physiological races belonging to seven groups were identified by using seven standard Chinese rice blast identifying varieties. Results showed that the dominant groups could be ranked as ZA, ZD, and ZB, with the occurrence frequencies of 47...
Soybean meal (SBM) is commonly used for livestock feeds, but its application in diets for livestock is limited due to some antinutritional factors. The contents of methionine and lysine of soybean meal were promoted by Bacillus natto and Leuconostoc mesenteroides fermentation, benefial for the livestock feeds. It was crude protein (CP) 56.8%, methionine 43.56 mg • g −1 , and lysine 74.87 mg...
The microsporogenesis and male gametophyte development of Euphorbia pulcherrima were studied with paraffin section method. The results showed that the anther of Euphorbia pulcherrima had four chambers. The development of anther wall was dicotyledonous type; its wall consisted of epidermis, endothecium, middle layer and tapetum. The mature male gametophyte development experienced seven major stages...
Tisplatin is one of the valuable icancer agents against several types of neoplasm. However, nephrotoxicity is the major adverse effect representing in cisplatin therapy. In this study, the animal tests detecting protective effects of a natural compound, Decursin, on cisplatin-induced nephrotoxicity were examined by using in vivo model. Pretreatment Decursin 10, 20 and 40 mg · kg −1 at 48,...
Based on the trace of origin and development process of low-carbon economy, the paper defined the concept of low-carbon agriculture. As a case, the development of low-carbon advantage and disadvantage of agriculture in Heilongjiang Province made a systematic analysis of factors; it based on the empirical and comparative analysis of low-carbon development in Heilongjiang Province and put forward countermeasures...
MicroRNAs (miRNAs) are a group of regulatory RNAs that regulate gene expression post-transcriptionally by the degradation or translational inhibition of their target messenger RNAs (mRNAs). Regulation is accomplished when the 22-25 nucleotide miRNAs bind to complementary sequences in the 3'-untranslated regions (UTR). One barrier to miRNA research is to find target genes. Although computational target...
PiggyBac transposon has demonstrated its long-term and stable transposition on genomes of various species but lacking of the evidence on farm animal genomes. In this study, we constructed a piggyBac transposon marked with enhanced green fluorescent protein (eGFP) and showed efficient transposition in porcine somatic cells and cloned embryos. Our results demonstrated that piggyBac transposase could...
This study was to investigate the effects of cold stress on the contents of total antioxidant capacity (T-AOC), malondialdehyde (MDA) and superoxide dismutase (SOD) in duodenum, jejunum and ileum of chickens. A total of 80 15-day-old male chickens were treated by cold stress with the duration of the acute cold stress being 1, 3, 6, 12, and 24 h, and the chronic cold stress was 5, 10, and 20 days,...
The somatic cell nuclear transfer (SCNT) technique has been applied successfully in a range of mammalian species giving rise to offspring, however, the efficiency of development to term has remained low. Oocyte meiotic arrest is an important option to make the SCNT more flexible and increase the number of cloned embryos produced. This paper showed that the use of butyrolactone I to arrest the meiotic...
Five F 2 segregation populations, derived from crosses between the susceptible japonica cultivars (cvs.) Kongyu131 and donor cvs. Aichi Asahi (AA), BL1, Digu, Pai-kan-tao (PKT) and Oryzica Llanos 5 (ORL5), were used to evaluate their natural resistance to blast in cold region. The field test of their blast resistance was conducted in 858 Farm, which showed that Aichi Asahi, BL1and Digu were...
Value analysis of grain production influencing factors is a complex decision problem. This paper introduced a modified Analytic Hierarchy Process (AHP) accumulation factor, namely Solving Weight by AHP's Accumulation Factor Sequence Evaluating Data. We used the arithmetical average to replace the expert marking, so that the possible decision mistakes by the subjective judgments could be avoided. We...
