摘要: Banana ( spp.) is an important staple food, economic crop, and nutritional fruit worldwide. Hybridization is seriously hampered by the long generation time, polyploidy, and sterility of most cultivars. Establishment of an efficient regeneration and transformation system for banana is critical for their genetic improvement. An efficient and reproducible transformation system for banana using direct organogenesis was developed. Media containing benzylaminopurine (BA) combined with one of four other growth regulators was evaluated for the regeneration efficiency of five cultivars and the ability to induce/support development of new banana shoots. The result indicated that the greatest number of shoots per explant for all five cultivars was obtained using MS medium supplemented with 8.9 mmol·L BA and 9.1 mmol·L thidiazuron (TDZ). In 240–270 d, one immature male flower could regenerate between 380 and 456, 310–372, 200–240, 130–156, and 100–130 well-developed shoots for Gongjiao, Red banana, Rose banana, Baxi, and Xinglongnaijiao, respectively. Such a system will facilitate molecular breeding and functional genomics of banana.

摘要:

Cronobacter spp. (formerly Enterobacter sakazakii) are special foodborne pathogens. Cronobacter infection can cause necrotizing enterocolitis, sepsis and meningitis in all age groups, especially neonates and infants, with a high fatality of up to 80%, although the infection is rare. Outbreaks of Cronobacter infection are epidemiologically proven to be associated with contaminated powdered infant formula (PIF). Cronobacter spp. can resist dry environments and survive for a long period in food with low water activity. Therefore, Cronobacter spp. have become serious pathogens of neonates and infants, as well as in the dairy industry. In this review, we present the taxonomy, pathogenesis, resistance, detection and control of Cronobacter spp.

摘要:

Agroecosystems in water-limited contexts— Mediterranean, semi-arid and arid climatic zones—are too frequently degraded systems that will not provide the needed ecosystem services to ensure a future of sustainable agricultural production. The processes that have created this situation continue and are being accelerated by anthropogenic climate change. Increasing arboreal vegetation in these areas through agroforestry is an important strategy to conserve and improve their agroecosystems. Actinorhizal trees and shrubs in the Casurinaceae have a unique set of adaptations for heat and water stress, and/or infertile to hostile soils. Central Anatolia, Turkey is particularly at risk of increasing aridity and further degradation. Therefore, species of Allocasuarina and Casuarina have been evaluated for their potential use in agroecosystem improvement in semi-arid areas with a focus on Central Anatolia. Based on a semiquantitative environmental tolerance index and reported plant stature, eight species were identified as being of high (Averticillata and Cpauper) to moderate (AacutivalvisAdecaisneanaAdielsianaAhuegelianaCcristata and Cobesa) priority for assessment, with none of these species having been adequately evaluated for agroforestry deployment in semi-arid agroecosystems in any context.

摘要: β-amylase (BAM) is an important enzyme involved in conversion of starch to maltose in multiple biological processes in plants. However, there is currently insufficient information on the BAM gene family in the important fruit crop banana. This study identified 16 genes in the banana genome. Phylogenetic analysis showed that MaBAMs were classified into four subfamilies. Most in each subfamily shared similar gene structures. Conserved motif analysis showed that all identified MaBAM proteins had the typical glyco hydro 14 domains. Comprehensive transcriptomic analysis of two banana genotypes revealed the expression patterns of in different tissues, at various stages of fruit development and ripening, and in responses to abiotic stresses. Most s showed strong transcript accumulation changes during fruit development and late-stage ripening. Some showed significant changes under cold, salt, and osmotic stresses. This finding indicated that might be involved in regulating fruit development, ripening, and responses to abiotic stress. Analysis of five hormone-related and seven stress-relevant elements in the promoters of further revealed that BAMs participated in various biological processes. This systemic analysis provides new insights into the transcriptional characteristics of the genes in banana and may serve as a basis for further functional studies of such genes.

摘要:

废物处置和能源危机是大多数国家面临的重要挑战。水果加工业每天产生数吨废物,其中大部分来自香蕉农场。厌氧消化(AD)技术已被应用于废水、污泥、食物垃圾和农业剩余物的处理,其主要目的是生产能源和消除废物。本研究探讨有机负荷(OL)和牛粪(CM)添加对处理香蕉皮废料(BPW)时AD性能的影响。在OL为每升18 g和22 g挥发性固体(gvs)时,CM含量为10%、20%和30%的香蕉皮(BP)每日最大沼气产量分别为50.20 mL·gvs–1、48.66 mL·gvs–1、62.78 mL·gvs–1和40.49 mL·gvs–1、29.57 mL·gvs–1、46.54 mL·gvs–1。然而,每日沼气产量与OL或CM含量没有明显的相关性。此外,动力学分析表明,一阶模型和锥体模型的动力学参数受工艺参数的影响。

摘要:

香蕉假茎粉末等天然吸附剂对于去除废水中的重金属元素具有非常重要的作用。现有的去除重金属元素的常规方法难以满足水资源循环和化学工业的需求。本文论证了利用天然物质处理废水的可能性。利用环境扫描电子显微镜(ESEM) 和傅里叶变换红外(FTIR) 光谱学分析方法,研究了香蕉假茎粉末吸附铅离子前后的变化。实验采用批处理方法研究了水溶液中铅离子去除的效果。通过改变初始pH 值、吸附剂用量、初始铅离子浓度、吸附时间等参数,研究了吸附动力学的影响。结果表明,在水溶液pH 值为5.5 时,香蕉假茎粉末达到零电荷点。采用吸附等温线和动力学模型分析实验数据,采用朗缪尔吸附等温式拟合铅离子在香蕉假茎粉末表面的吸附作用。实验表明,香蕉假茎粉末对铅离子的吸附量为34.21 mg·g−1,与拟二级动力学模型相匹配。此外,采用响应面分析法确定了铅离子吸附的最佳条件,铅离子的去除率高达89%。

摘要: A large number of expressed sequences tags are available for spp., which provides an opportunity to understand genomic organization of the transcribed regions. Here, we report a detailed analysis of repetitive elements including tandem repeats (TRs) and transposable elements (TEs) in the transcribed region of the spp. On average, 22% of the expressed sequence tags (ESTs) contain TRs. The relative density of TR classes is highly taxon-specific. For instance, has a high relative density of mononucleotide repeats, whereas dinucleotide repeats are rare. The proportions of 2–6, 7–30 and 31–50 bp repeats were almost identical in all studied species except for and . We found that<1% of the citrus ESTs have a similarity with transposable elements. Transcriptional activity of transposable element families varied even within the same class of elements. A high proportion of transcriptional activity was observed for -like TEs compare to other TE classes. While TEs are relatively rare, TRs are abundant elements in ESTs of citrus. The high proportion of TRs that have a unit size longer than 6 bp raises the question about a possible functional or evolutionary role of these elements.

Sustainable intensification of agriculture in Africa

摘要: Sustainable intensification is a key component of agricultural development in Africa, urgently needed to wean the continent off foreign food supply and to limit agricultural farmland expansion. It is expected that a relatively small fraction of farmers will adopt fertilizer technology, as profits in current economic settings are relatively small while risks are considerable with varying prices and uncertain yield responses. Many smallholders depend on off-farm income and local markets for food supply. Structural adjustments are therefore needed to allow management of larger units of land by trained farmers willing to take this opportunity, while recognizing land right sensitivities. There are large opportunities for African commodity crops to improve food security, including cassava and East African highland banana that strongly respond to fertilizer with limited environmental risks under good management. This requires investments in better functioning markets, local fertilizer production facilities that can produce regional crop blends and cost-efficient distribution networks, providing balanced fertilizers for African farmers.

摘要: Cold stress is an environmental factor affecting plant development and production. Recently, microRNAs (miRNAs) have been found to be involved in several plant processes such as growth regulation and stress responses. Although miRNAs and their targets have been identified in several banana species, their participation during cold accumulation in banana remains unknown. In this study, two small RNA libraries were generated from micropropagated plantlets of grown at normal and low temperature (5°C). A total of 69 known miRNAs and 32 putative novel miRNAs were detected in the libraries by Solexa sequencing. Sixty-four cold-inducible miRNAs were identified through differentially expressed miRNAs analysis. Among 43 miRNAs belonging to 26 conserved miRNA families with altered expression, 18 were upregulated and 25 downregulated under cold stress. Of 21 putative novel miRNAs with altered expression, four were downregulated and 17 upregulated. Furthermore, eight miRNAs were validated by stem-loop qRT-PCR and their dynamic differential expression was analyzed. In addition, 393 target genes of 58 identified cold-responsive miRNAs were predicted and categorized by function. These results provide important information for further characterization and functional analysis of cold-responsive miRNAs in banana.

摘要:

1963年以来,我国先后从国外引进3种大米草,分布在18000 km海岸带上,经过近40年的引种、驯化和栽培,种植面积已达到36000 hm2。实践证明大米草和互花米草适应于中国海岸带自然环境而正常生长发育,具有明显的促淤造陆、保滩护岸,环境保护等生态功能,并有显著的经济效益,是一种改造滩涂的优良植物,也是一种盐渍土裸地植物群落形成的先锋植物,已作为一个外来种被列入《中国植物志》、《中国高等植物图鉴》和各种地方植物志中。文章认为应客观地评估大米草的功与过。大米草和互花米草繁殖较快的原因是由于富营养化的结果,然而对环境、种群和人并未构成侵害行为,在北方海岸带区域尤未发现任何异常现象,不可认定大米草和互花米草是属于有害的生态入侵种。

摘要: The aim of this study was to identify the intermediates in clofibric acid degradation under various advanced oxidation processes, namely ultraviolet (UV), UV/H O , vacuum ultraviolet (VUV), VUV/H O , and solar/TiO processes, as well as to assess the toxicity of these intermediates. Eleven intermediates have been detected by gas chromatography-mass spectrometer, most of which were reported for the first time to our best knowledge. Combining the evolution of the dissolved organic carbon, Cl and specific ultraviolet absorption at 254 nm, it could be deduced that cleavage of aromatic ring followed by dechlorination was the mechanism in solar/TiO process, while dechlorination happened first and accumulation of aromatic intermediates occurred in the other processes. Different transformation pathways were proposed for UV-, VUV-assisted and solar/TiO processes, respectively. The acute toxicity was evaluated by means of T spp. bioassay. It was believed that aromatic intermediates increased the toxicity and the ring-opening pathway in solar/TiO process could relieve the toxicity.
