    Based on the observation of the apricot tree phenology and the daily average temperature, minimum temperature, precipitation, and sunshine hours of the corresponding period in Kashi City, and Yecheng, Shache, Bachu and Maigaiti County of Kashi Prefecture of Xinjiang, the relationship between the beginning of apricot flowering and meteorological factors was analyzed using correlation analysis and regression analysis. The results show that among the various meteorological factors, the lowest temperature has the greatest impact on flowering, followed by the average temperature and sunlight, and the precipitation and other meteorological factors have less influence. The temperature in the study area is positively correlated to the flowering period of the apricot tree. From 1984 to 2019, the minimum temperature and average temperature increase in Kashi from late February to late March was 0.2-1.7℃/10 years. The apricot flower bud expansion period, flower bud opening period, the beginning of flowering was ahead of time by 5.3 to 8.7, 3.1 to 5.6, and 2.2 to 3.6 d/10 a, respectively. In apricot flowering period forecasting service, the daily average temperature of north, south and east of Kashi passed through ≥0℃ from day 1 to 34, day 39 to 41, day 37 to 39, or the accumulated temperature passed ≥0℃ before flowering reaching 250, 270-280, and 250-270℃, respectively, or the sliding average temperature of 5 days before the beginning of flowering passed≥12℃ could be used as the basis for predicting the beginning of apricot tree flowering.

    The study aims to provide references for crop production in winter wheat area of Kashgar. The data of temperature, precipitation, sunshine duration from 1981 to 2014 during the growth period of winter wheat in Kashgar was used to study the variation characteristics of climate factors and their effects on winter wheat growth and development by the climate statistical method. The results indicated that the annual average temperature change during winter wheat growth in Kashgar showed an increasing trend. The precipitation showed a decreasing trend in the first two months after winter (March and April), and an obviously increasing trend in the rest time. Meanwhile, the effective accumulative temperature and the sunshine duration showed an increasing trend. Each development stage of winter wheat was ahead of schedule in different degrees during recent 34 years, especially the early stage and the jointing stage, but the overwintering stage showed a trend of delay. The temperature, effective accumulative temperature and the sunshine duration were negatively correlated with each development stage of the winter wheat. In short, the main reason for the advance of winter wheat growth period was the increase of temperature, effective accumulative temperature and sunshine duration. The impact of climate warming on winter wheat growth was significant in Kashgar.

    To improve soil nutrient utilization efficiency and deal with single manure application problems such as dosage, fertilizer efficiency, and nutrient leaching, “biochar”, “compost”, “biochar manure application”, “soil properties” and “crop nutrients” were used as keywords to search and summarize relevant literatures on sources of Web of Science, Google Scholar, China National Knowledge Internet and others. The results showed that: (1) biochar improved the maturity of composting, increased the abundance of microbial communities, and reduced the risk of nutrient leaching in organic fertilizers, thus effectively reducing the environmental impact of traditional composting; (2) manure combined with biochar could improve soil moisture condition, and increase the contents of the available phosphorus and available potassium of different types of soils. Meanwhile, it could also provide better living materials and an environment for soil organisms and microorganisms; (3) the combination of biochar and organic fertilizer could increase the yield of crops and improve the contents of nitrogen, phosphorus and potassium, while different types of crops responded to them differently. The combined application of biochar and organic fertilizer enhanced soil fertility and plant nutrition, and its effect varied with the application rate, type of soil and crop and other factors. Our studies could provide a reference for efficient utilization of livestock and poultry manure resources in agricultural production.

    Microbial exopolysaccharides have important characteristics such as renewability, biodegradability, strong adsorption, anti-inflammatory, antioxidant, and antiviral properties. They have multiple applications in fields of food, pharmaceuticals, cosmetics, and environmental protection. Previous studies mainly focused on the isolation, purification and structure of microbial exopolysaccharides, but there were few reports on the relationship between the structure and function of microbial exopolysaccharides and the role of exopolysaccharides in environmental protection. In order to elucidate the structure-function relationship of microbial exopolysaccharides and expand their applications, this article reviews the impacts of monosaccharide composition, molecular mass, functional groups, glycosidic linkages, and surface morphology on their functions. Furthermore, potential applications of microbial exopolysaccharides in wastewater treatment, soil remediation, and antibiotic elimination for environmental protection are summarized. Due to the low yield and biological activity of microbial exopolysaccharides, their extensive industrial application is limited. It is expected that the yield of microbial exopolysaccharides can be enhanced through genetic engineering techniques, structural modification, and optimization of fermentation conditions and promote their development and application in environmental protection.

    Pesticide is an important input in agricultural production. Due to the restricting elements such as pesticide improper use, pesticide resistance and environmental factors, the effective utilization rate of pesticide is low. Pesticide pollution of soil can lead to soil dysfunction, and the exposure of pesticide may cause acute, chronic and long-term harm to human health. As a new material, biochar can be used to fix/degrade pollutants and minimize the risk of soil pollution with its high aromatic character, excellent absorbability and environmental friendliness. In this paper, the characteristics and formation mechanism of biochar, its adsorption mechanism of pesticides and the pathway of functionalization are briefly discussed by summarizing the research results at home and abroad.

    In order to remove the inherent complex resistance structure of lignocellulose and achieve efficient utilization of lignocellulose, new lignocellulosic pretreatment technologies have been improved continuously. As green solvents, Deep Eutectic Solvents (DESs) have the advantages of low cost, simple preparation, thermal stability, and designability. They have great application potential in promoting the pretreatment of lignocellulose and enzymatic hydrolysis, and have received widespread attention. Based on the analysis and summary of the research status and achievements at home and abroad, the research progress of synthesis and properties of DESs, pretreatment mechanism, enzymatic hydrolysis, and bioethanol conversion were discussed. It was pointed out that different hydrogen bond donors and different pre-treatment conditions had a significant impact on the lignin removal rate and glucose yield. It was believed that pretreatment of lignocellulose with DESs could greatly improve the saccharification rate. Prospects for DESs pretreatment mechanism, recycling, and process parameter optimization were proposed.

    With the increase of global temperature, heat stress has emerged as one of the major factors affecting plant growth and development. The substantial losses caused by heat, particularly for staple crops like rice, pose a significant impact on economic benefits. In order to unravel the molecular mechanisms underlying plant response to heat stress, the adverse effects of heat stress on the morphology, physiology, biochemistry and photosynthesis have been presented. Furthermore, the three molecular mechanisms employed by plants to cope with heat stress, including signal transduction pathways, transcriptional factor regulatory networks and the expression of heat-resistance related genes have been introduced as well. Based on these insights, this review suggests that bioinformatics, genetic engineering, cell biology and molecular biology may be further employed as tools for understanding the molecular mechanisms of heat stress in plants. At last, this review offers a prospective outlook on future research directions in this field.

    The increasing deterioration of the environment has forced people to abandon the concept of high-fertilizer production and shift to the concept of low-fertilizer green production. This study reviewed different metabolic levels, and morphological, physiological and molecular responses of plants from five aspects: enzymes involved in nitrogen metabolism, nitrogen assimilation pathways, primary metabolism, secondary metabolism and nitrogen metabolism-related genes under low nitrogen stress, discussed the low nitrogen tolerance strategies of plants at different growth stages, and expounded the enzymes related to nitrogen use efficiency (NUE) and their regulatory mechanism in the process of resisting nitrogen stress. It is proposed that in the future, according to the differences of low nitrogen tolerance of different plants or different growth periods of the same plant, and the relationship of key gene expression products, the molecular response mechanisms of plants under low nitrogen stress could be systematically and comprehensively studied from multiple disciplines and perspectives, so as to provide theoretical reference for the research on plant nitrogen metabolism involved in low nitrogen stress.

    Soil salinization is the main reason of economic crop failure and severely limits agricultural production. As a primary abiotic stress factor, high salinity results in the disorder of ionic equilibrium, eventually leads to the reduction of crop yield and the increase of mortality rate. Abscisic acid (ABA), which is one of the five phytohormone groups, is generally acknowledged as a resistant hormone and plays a positive role in plant salt stress response. The author reviewed the correlation, mechanism and signal transduction pathway of ABA in plant salt stress response during recent years, and forecasted researches in the future. The analysis indicated that ABA could response to plant salt stress and also played an important role in plant salt tolerance signal transduction pathway. With the formation of a series of molecular adaptability mechanisms, plant could resist high salinity stress via self-response.

    Transcription factors are a kind of proteins that play an important role in the regulation of plant growth and development, as well as in plant response to environmental variation. They usually contain a DNA-binding domain, a transcription regulation domain, an oligomerization site and a nuclear localization signal inside their DNA sequence. WRKY proteins had been identified as one of the important transcription factors in plants. There have been 103 WRKY genes which were predicted in rice genome by data mining and the annotation of the biological function of these genes had the important value for the functional genomics of rice. SUSIRI gene was one of the WRKY transcription factor genes cloned from the Oryza sativa sub. Japonica var. Nipponbare and its ORF was 1755 bp long, encoding a polypeptide of 584 amino acids with two typical WRKY domains. In this study, based on nucleotide sequence of the SUSIRI gene, its biological function in gene regulation in rice had been further elucidated. Firstly, the structure and functions of the predicted protein were analyzed by bioinformatics tools while the Motif sequence of SUSIRI gene was analyzed by using EBI interpro database, the conserved domains of the protein was analyzed by NCBI CDD database; the hydrophilicity (hydrophobicity) of amino acid residues and the transmembrane domains of SUSIRI protein were analyzed by DNAMAN and CBS TMHMM. By using CBS Protcomp version 9.0 and Protfun software, the subcellular localization and function of protein were predicted. Secondly, the fluorescence expression vector of pNSUGFP driven by actin promoter was constructed by fusing the SUSIRI gene and GFP gene and was used to transform into epidermis cell of onion by Gene gun for detecting gene subcellular location. The prediction from bioinformatics showed that the SUSIRI gene had the greatest probability in function of transcription, transcription regulation or signal transduction in the rice cell with the value in prediction of 0.973, 1.598 and 0.602. Similarly, it had the greatest probability in participation of translation, central intermediary metabolism, fatty acid metabolism with the predicted value of 4.800, 1.490 and 1.265. Because of high content of hydrophilic amino acid residues among peptide sequences, the SUSIRI protein had hardly inserted into the membrane in the cell when it was likely to be localized within the cell nucleus since the strong nucleus location signal was detected from the sequence of amino acids. By using the fluorescence microscopy to observe the onion epidermic cells, the GFP protein was shown to express along the cell wall in the control, but the fused protein of SUSIRI-GFP expressed strongly in the cell nucleus. The result indicated that the SUSIRI gene was likely to be the transcription factor regulating the intermediary metabolism in rice and playing the role during the gene transcription. SUSIRI protein could be localized in nucleolus which is an obvious feature of transcription factor of SUSIRI gene determined by the experiment.

    Transcription factors are important regulatory proteins that regulate gene expression. Transcription factors and the related cis-acting elements of promoters which bind to them both play the role of molecular switches in gene expression, therefore it is particularly important to explore the interaction of transcription factors with promoters. In order to study the regulation mechanism of transcription factors on downstream target genes when plants are subjected to stress, this paper summarized the main transcription factor families involved in stress, the identification of transcriptional activation activity of transcription factors, the interaction analysis technologies between transcription factors and promoters and their applications in plants’ response to stress, which could provide references for the comprehensive and in-depth study of the gene expression regulation mechanism of plants in response to stress.

    The paper aims to illustrate the key growth stages of olive and the relationship between botanical characteristics and meteorological variables. In Wudu mountain, the botanical characteristics of olive and the meteorological observation data from 2012 to 2015 were collected. Based on the leading indicator of average temperature in January and several other factors such as annual average temperature, annual average relative humidity, and annual sunshine hours, an olive suitable climate division index system was built for Wudu mountain. The fine climate division map for olive cultivation suitability was made by applying GIS technology. The results indicated that: the most suitable olive planting areas were located in the valley plains, basins, and shallow mountainous areas below the elevation of 1300 m in the southern Wudu and Bailong river basin; suitable olive planting areas were located in the valley plains, basins, and shallow mountainous areas in the elevation of 1400- 1500 m; the other areas were unsuitable for olive growing which were mainly in the northwest Wudu and other places above the elevation of 1500 m. The results can guide scientific planning and rational arrangement for Wudu mountain and make the best of climate resources to develop olive industry, and also provide a scientific basis for prevention and mitigation of meteorological disasters.
