BETWEEN HONOR AND HUMILIATION: STARTING FROM THE RIGHTS AND WRONGS BY FOREIGN INVESTMENT (Ⅱ)

Money Scatters Everywhere in China It is said that the saving ratio of China is close to 40%.Authoritative persons thus analyze in this way: theoretically, 40% saving ratio of a country is enough tosustain its economic growth at the rate over 10% even at thetime of its economic take-off; practically, "Four Tigers" inAsia achieved high economic growth in 1960s and 1970s withtheir saving ratio only about 30%. Conclusion: with the 40% saving ratio, or domesticfunds, China can fully sustain the growth rate of 8-9 % thisyear. The question remains: why do we want to introduceforeign funds? Why do we allow foreigners to come and maketens percent of profit while we can only get bits of

BETWEEN HONOR AND HUMILIATION:——STARTING FROM THE RIGHTS AND WRONGS BY FOREIGN INVESTMENT(Ⅲ)

The Poor Becomes Even Poorer, And TheRich Becomes Even Richer-The Mat-thew Effect In Foreign Investmenthe nature of the capital is keen on the rich but cold-shoul-der the poor. If you are rich, dollars, pounds or RMBs wouldgreet you with a genial smile. If you are poor, you will beignored. Maybe, you will be provided with some "grants", to showtheir generosity and mercy. Nevertheless, with regard to invest-ment, not a chance.Therefore, foreign investment in China takes the followingshape:by regions, the realized foreign investment in the 18 prov-inces and autonomous regions of the Mid-West accounts for lessthan 10% of the national total even though the area is in greatneed of funds; by industrial sectors, agriculture has only a tinyshare of less than 2% of total foreign investment in China eventhough it cniovs first Prioritv in economic development and de-mands immediate strengthening; likewise, foreign investment

ChMYB1-ChbHLH42-ChTTG1 module regulates abscisic acidinduced anthocyanin biosynthesis in Cerasus humilis

Cerasus humilis is a kind of economic fruit tree peculiar to China,which is widely used in the food,landscape,and pharmaceutical industries.Anthocyanins are a phenolic metabolite that plays an essential role in fruit coloration.However,the regulatory network of C.humilis in anthocyanin biosynthesis is still unclear.In this study,the R2R3-MYB transcription factor ChMYB1 was isolated from the full genome of the species.Yeast one-hybrid,dual-luciferase assays,and GUS staining showed that ChMYB1 significantly increased anthocyanin contents in C.humilis fruit by promoting the expression of ChCHS and ChUFGT by binding MBS(MYB-binding elements).ChMYB1 interacted with ChbHLH42and ChTTG1 to form the MBW complex and further enhanced the expression of ChUFGT.In addition,abscisic acid(ABA)treatment promoted the expression of ChMYB1 and anthocyanin accumulation in C.humilis fruit.Interestingly,ABA treatment enhanced the interaction between ChMYB1 and ChbHLH42.Furthermore,ChABI5 inhibited the interaction between ChMYB1 and ChbHLH42.Our data elucidated the primary molecular mechanism of anthocyanin biosynthesis in C.humilis fruit,deepening the understanding of the regulatory network affecting anthocyanin metabolism in edible fruit crops.

Selection of Suitable Area and Analysis of Adaptability Difference of Prunus humilis

This paper delves into and assesses the differences in biological traits and fruit nutritional composition of 3 varieties of Prunus humilis introduced from 2 different regions.Results showed that(i)the contents of protein,total sugar,and calcium of No.5 variety were higher those of the other 2 varieties,which was recognized as the most suitable variety for fresh fruit;(ii)the comparison of leaf areas index and fruit shape index of 3 varieties shows that the fruit shape index and individual fruit weight of the introduced varieties were higher than those of the control,the diameter of individual fruit of the introduced varieties higher than that of the control indicated that they had a higher fruit hardness,more dry matter accumulation and better fruit quality,and that the introduction region was more suitable for scale-up of P.humilis;(iii)there was a positive correlation with the number of fruiting branches and there was a significant negative correlation with individual fruit weight,while the leaf area had a significant negative correlation with the number of fruiting branches.The introduced varieties can develop normally in the 2 testing areas,notably,No.5 variety performed better than No.4 and No.6.Improving management is the prerequisite for maintaining proper number of fruiting branches and high yield.

Pectin fractions extracted sequentially from Cerasus humilis:Their compositions,structures,functional properties and antioxidant activities

Three pectin fractions(water-soluble fraction(WSF),chelator-soluble fraction(CSF),and sodium carbonatesoluble fraction(NSF))were obtained from Chinese dwarf cherry(Cerasus humilis)fruits.All of them were branched low methoxylated pectins with an amorphous or partially nanocrystalline nature and eight neutral monosaccharides(arabinose and galactose were most abundant).WSF,CSF and NSF had a degree of methylation(DM)of 35.82%,14.85%and 7.13%,uronic acid(UA)content of 76.02%,83.71%and 69.01%,and total protein content of 2.4%,2.1%and 8.8%,respectively.Their molecular weights were 340.31,330.16 and 141.31 kg/mol,respectively(analyzed by gel permeation chromatography(GPC)).WSF,CSF and NSF exhibited good rheological,thermal,emulsifying,emulsion-stabilizing,water-adsorbing,oil-binding,cholesterol-binding and antioxidant properties.NSF had the highest emulsifying,emulsion stabilizing,water-/oil-/cholesterol-binding and antioxidant capacities,followed by CSF.NSF had the highest viscosity(406.77 m Pa·s),flowability,and resistance to heat-induced changes/damage,which may be related to its lowest polydispersity index,DM and UA content and highest protein content.The three pectin fractions with desirable characteristics can be used as food additives/ingredients and dietary supplements.

Transcriptomic comparison to identify rapidly evolving genes in Braya humilis

The Brassicaceae species Braya humilis shows broad adaptation to different climatic zones and latitudes. However, the molecular adaptation mechanism of B. humilis is poorly understood. In China, B. humilis is mainly distributed on the QinghaiTibetan Plateau(QTP) and in the adjacent arid region. Previous transcriptome analysis of B. humilis has revealed that 39 salt and osmotic stress response genes are subjected to purifying selection during its speciation. To further explore the adaptation mechanism of B. humilis to an arid environment, OrthoMCL program was employed in this study and 6,268 pairs of orthologous gene pairs with high confidence were obtained between B. humilis and Arabidopsis thaliana. A comparative evolutionary analysis based on nonsynonymous to synonymous substitution ratio(Ka/Ks) was then conducted. There were 64 pairs exhibiting a Ka/Ks ratio more than 0.5 and among which, three instrumental candidate genes, T20487,T22576, and T23757, were identified with strong selection signatures(Ka/Ks >1). The corresponding A. thaliana orthologs are double-stranded RNA-binding domain protein, MADS-box family protein, and NADH-dehydrogenase subunit6, which is encoded by mitochondria genome. This report not only demonstrates the adaptation contribution of fast evolving nuclear genes, but also highlights the potential adaptive value of mitochondria gene to the speciation and adaptation of B. humilis toward the extreme environment in an arid region.

Correlation analysis shows that community biomass was correlated positively with the dchness index （ P 〈 0.01 ）, and biodiversity index was correlated positively with the aboveground biomass and dchness index （ P 〈 0.01 ）. [ Conclusion] The Kobresia humilis community I has reasonable structure and large coverage of ground vegetation, which play an important role in maintenance of biodiversity and ecosystem function.

Contribution of Chamaerops humilis L. (Arecaceae) in Conservation in Situ of Soil Resources in the Tlemcen Region (Western Algeria)

In recent years, the anthropic action on scrubs in the region of Tlemcen (a province in western Algeria) has represented a threat to the groups of Chamaerops humilis L. (Arecaceae). The main purpose of the present investigation is to highlight the relationship between Chamaerops humilis and its biotope. Taking advantage of the refurbishment works in the study area, clumps of Chamaerops humilis, freshly dug by machinery, were collected and used to conduct some measurements. A total of 34 clusters were considered. The main parameters to be studied are: 1. The height of the tangle of roots and the number of roots in each cluster;2. The weight of soil trapped between roots;3. Physico-chemical properties of soil in which taxa grow. The results obtained showed that the average weight of soil retained by the clumps was important (70.3 kg);the average height of the tangle was 68.4 cm and the average number of roots was 382. The tangle of roots, of various stocks of Chamaerops humilis, creates a root network, very tangled in its upper part, thereby trapping a significant amount of soil. The statistical analyses of pairs of parameters, considered in the present work (height of the tangle, mass of soil trapped by roots and number of roots), were found to be highly correlated. These analyses allowed identifying the relationships existing between the studied parameters. They also helped to deduce the role of the taxon in the in situ conservation of edaphic potential.

Comprehensive transcriptomic analysis of developing seed in Cerasus humilis for lipid related gene discovery

Cerasus humilis is a woody shrub with increasing economic importance. Due to its high oil content in seed with desired fatty acid(FA) composition, C. humilis has been considered as a potential woody oilseed crop in China. However, FAs accumulation and related molecular mechanisms of FA biosynthesis in C. humilis seed have not been elucidated well. In this study, oil contents and FA compositions of developing C. humilis seed were analyzed. The total oil content in mature seed reached 48.7% while unsaturated FA concentration reached a high level of 96.2%. Three c DNA libraries of C. humilis developing seed were constructed at the beginning and 2 fast oil-accumulation stages, followed by Illumina sequencing with the platform of HiSeq^TM 2000. Differentially expressed unigenes(DEGs) were identified during the respective seed development stages to investigate transcription dynamics. Among DEGs, 82 unigenes were identified as being closely involved in de novo FA and triacylglycerol(TAG) biosynthesis. Surprisingly, among DEGs involved in TAG biosynthesis, expression of unigenes encoding GPATs(glycerol-3-phosphate acyltransferase) were relatively low and unigenes encoding LPAATs(lysophosphatidic acid acyltransferase) were highly expressed, suggesting that LPAAT contributed more in storage lipids metabolism in C. humilis seed. Genes encoding DGAT2(diacylgycerol acyltransferase2) were the most highly expressed while expression of DGAT1 was very low, suggesting DGAT2 was the dominant DGAT which catalyzed TAG biosynthesis. To verify these results,10 unigenes were selected and their expression patterns were analyzed by quantitative RTPCR. These data provided comprehensive information for understanding the molecular mechanism of FA and TAG biosynthesis in C. humilis seed.
