The development of the Internet brought us into an era of big data information, give people bring convenient while and also make people ragged when choosing the required information and recommendation system arises at the historic moment, and get the wide attention and applications. Therefore, to enhance the traditional method, we propose a novel intelligent recommendation algorithm based on Web data mining technique under the background of the deep neural network. Firstly, we review the state-of-the-art web data mining algorithms and revise the traditional ones with the parallel data mining algorithm on the multiple processors to perform tasks that will enhance the accuracy and efficiency. Then, we analyze basic neural network model through the inner connection and weight transfer. Later, we introduce the deep network structure to enhance the traditional network. Finally, we combine the revised prior theories into the recommending tasks for enhancement. The experimental analysis show that our algorithm accuracy is enhanced by the extent of 56% and overall time is reduced to the 87% of traditional ones which proves the feasibility. Later, more optimization work will be introduced to modify the current methodology.

The genetic diversities and relationships of 10 Chinese indigenous pig breeds and three exotic pig breeds have been evaluated using 26 microsatellites recommended by the Food and Agriculture Organization & the International Society of Animal Genetics (FAO-ISAG). The allele frequencies, genetic heterozygosity (H) and polymorphism information content (PIC) have been calculated. The results showed that genetic diversity of Chinese indigenous pig breeds is higher than that of the introduced pig breeds. The clustering of 10 breeds is generally consistent with their geographical distribution.

Iron deficiency is one of the most serious nutrient limiting factors that affect rice plant growth and photosynthesis. Several phytohormones, including auxin, participate in iron uptake and homeostasis. However, how auxin signaling is involved in iron deficiency-induced inhibition of shoot growth and photosynthetic efficiency is largely unknown. The Nipponbare (NIP) seedlings displayed typical chlorotic symptoms, biomass reduction and photosynthesis depression when subjected to iron deficiency. We measured the soluble Fe content in the shoots under different conditions. The soluble Fe content in the shoots under Fe deficiency was increased by 1-naphthoxyaceticacids (1-NOA) treatment and was decreased by 1-naphthaleneacetic acid (NAA) treatment. Blocking (1-NOA treatment) or enhancement (NAA treatment) of auxin signaling also affects photosynthetic parameters under Fe deficiency conditions. Furthermore, rice microarray data (GSE17245 and GSE39429) were used to analyze the relationship between iron deficiency responses and auxin signaling in shoots. Most iron deficiency response gene expression levels in the shoots increased under exogenous auxin treatment, and most auxin early response gene expression levels responded to iron deficiency. It suggested that there is a crosstalk between iron deficiency signaling and auxin signaling. Our results indicated that iron deciencyinduced growth inhibition and photosynthesis depression were mediated by systemic auxin signaling.

Senescence of Hosta ventricosa flowers was firstly characterized as ethylene-sensitive since the deterioration of the tepal was accompanied by increased endogenous ethylene biosynthesis. The full-length cDNAs and DNAs of 1-aminocyclopropane-1-carboxylic acid (ACC) synthase (ACS) and ACC oxidase (ACO) involved in ethylene biosynthesis were cloned from H. ventricosa flowers. The HvACS ORF with 1347 bp and two introns, encoded a polypeptide of 448 amino acids showing 79% homology with that in Musa acuminata. The HvACO ORF contained 957 bp and three introns, encoding a 318-residue polypeptide showing 83% homology with that in Narcissus tazetta. The timing of the induction of HvACS expression was in correspond to the timing of the increase in ethylene production, and that the up-regulation of HvACO transcript was closely correlated with an elevated ethylene production, but underwent a down-regulation in wounded leaves with elevated ethylene emission. The results, together with expression analysis in vegetative tissues, suggested that both HvACS and HvACO were specifically regulated by flower senescence.
