Isolation and properties of an extremely thermophilic xylanolytic bacterium
Anming Li,Hai Zhao
Science China Life Sciences , 1998, DOI: 10.1007/BF02882887
Abstract: A strain of extremely thermophilic, anaerobic, xylanolytic bacterium was isolated from the hot spring in Kangding County, Sichuan Province, and it was gram-reaction negative, immobile, non-sporeformative with its cells arranged single or in pairs, 0.7–1.0 μm wide and 2.0–5.0 μm long. After being cultured at 75C for 3 d on xylan agar rolling tube, its colonies were rounded, convex, smooth in margin and transparent, and could not produce pigments, but could produce carbon dioxide, hydrogen, lactic acid, acetic acid and trace ethanol during the fermentation of xylan.

Induction of cranial and posterior trunk neural crest by exogenous retinoic acid in zebrafish
Ming Li,Ying Su,Anming Meng
Chinese Science Bulletin , 2002, DOI: 10.1360/02tb9248
Abstract: Retinoic acid (RA) plays an important role in development of vertebrate embryos. We demonstrate impacts of exogenous RA on the formation of neural crest cells in zebrafish using specific neural crest markers sox9b and crestin. Treatment with all -trans RA at 10 7 mmol/L at 50% epiboly induces sox9b expression in the forebrain and crestin expression in the forebrain and midbrain, resulting in significant increase of pigment cells in the head derived from the cranial neural crest. In addition, RA treatment induces expression of sox9b and crestin in the caudal marginal cells of the neuroectoderm during early segmentation. Earlier commitment of these cells to the neural crest fate in the posterior margins leads to abnormal development of the posterior body, probably by preventing mingling of ventral derived and dorsal-derived cells during the formation of the tailbud.

Science China Life Sciences , 2001, DOI: 10.1007/BF02879320
Abstract: An endogenous filariform fungus has been separated from a tree named Taxus growing in the Aba region, Sichuan, China. The fungus is fermented in fluid medium for 3 weeks at 25°C, then the HPLC and MALDI-TOF analysis of the zymotic fluid show that the zymotic fluid contains taxol. So it is a fungus which can produce taxol. It is namedTaxomyces sp. temporarily.
ABC model and floral evolution
Guisheng Li,Zheng Meng,Hongzhi Kong,Zhiduan Chen,Anming Lu
Chinese Science Bulletin , 2003, DOI: 10.1007/BF02901752
Abstract: The paper introduces the classical ABC model of floral development and thereafter ABCD, ABCDE and quartet models, and presents achievements in the studies on floral evolution such as the improved understanding on the relationship of reproductive organs between gnetophytes and angiosperms, new results in perianth evolution and identified homology of floral organs between dicots and monocots. The evo-devo studies on plant taxa at different evolutionary levels are useful to better understanding the homology of floral organs, and to clarifying the mysteries of the origin and subsequent diversification of flowers.
Characterization and expression pattern ofpouII1, a novel class II POU gene in zebrafish
Ming Li,Ying Cao,Zhixing Zhao,Shuo Lin,Anming Meng
Chinese Science Bulletin , 2001, DOI: 10.1007/BF02900572
Abstract: POU domain transcription factors that share a conserved DNA-binding domain, POU domain, are important regulators for the development of embryos in various animal species. A novel zebrafish POU domain gene,pouII1 has been cloned. ThepouII1 cDNA is 2080 kb in length and encodes a putative polypeptide of 596 amino acids. It is placed into class II POU family since it shares a high degree of homology with the known members of this family. Northern hybridization identifies a major transcript of approximately 2.1 kb that was present in embryos at the single-cell stage throughout 24 h postfertilization. The whole mountin situ hybridization shows thatpouII1 transcripts are present in the single-cell embryos, strongly suggesting that these transcripts are of maternal origin. During early development of the embryos,pouII1 mRNA was ubiquitously distributed in all cells and tissues. The transcripts are gradually limited to brains and become completely undetectable by day 3. To our knowledge,pouII1 is the first class II POU gene identified in zebrafish.

Abstract: Snow plays an important role in balancing Earth’s surface heat and generating streamflow in arid areas.In Xinjiang,the Tianshan Mountain is abundant in seasonal snow.Seasonal snow melt is the primary source of water,especially for river systems over mountainous areas.There is about 9.63×109m3 snow melt and ice melt in the Tianshan Mountain contributed to streamflow every year.The Kaidu River originates from the central part of the Tianshan Mountain,and is primarily supplied by mixed water from snow melt and rain.The temporal and spatial variations of snow cover depend on many factors,such as air temperature,precipitation,local vegetation cover,wind direction,wind speed,and solar radiation.As a result,the snow cover is extremely sensitive to climate change,which could lead to changes in streamflow in spring and summer.The changes in streamflow would subsequently affect the fragile environment in arid areas.Effectively monitoring snow cover is therefore an essential requirement for water resources management over the region.MOD10A2 comprises the 8-day composite snow cover product with spatial resolution of 500 m from the Moderate Resolution Imaging Spectroradiometer(MODIS)/Terra satellite.In this study,MOD10A2 snow products during the period 2000-2010 were employed to detect variation in snow cover,impact of snow cover change on streamflow and baseflow,as well as relationships among meteorological factors,snow cover,and streamflow.Results show that there was a seasonal change in snow cover,and the maximum value occurred in winter and the minimum in summer.The total snow cover showed a slightly decreasing trend from 2000 through 2010.The snow cover decreased in summer and winter,and there was no obvious change in spring and autumn.The correlation between snow cover and meteorological variables suggests that there existed a stronger correlation between snow cover and temperature in spring and winter than in summer.Snow cover had marked correlation with precipitation in winter.In addition,both streamflow and baseflow showed appreciable correlation with snow cover in spring.Temperature had a significant effect on streamflow and baseflow in spring and autumn,but streamflow and baseflow were more sensitive to precipitation in summer than in other seasons.Temperature was the major factor affecting changes in snow cover in the Kaidu River basin.Temperature and snow cover showed the most significant influence on streamflow and baseflow in spring and autumn,whereas precipitation was the primary factor affecting streamflow and baseflow in summer.

Abstract: In this study, an ASD spectrometer made in USA is used to derive the hyperspectral data of cotton leaves in canopy in north Xinjiang. The integral area variables of red edge are used to estimate the total nitrogen (TN) content in cotton leaves in canopy. The first order differential of reflective spectra is carried out. The analysis methods based on the spectral position variables are derived from the first order differential spectral data. The analysis on the correlation between the integral area of red edge (SDr, regarded as the independent variable) and the TN content (regarded as the function) is carried out, and the correlation mathematical model between the integral area of red edge and the TN content in canopy leaves of cotton varieties named as Xinluzao No.6 is developed. The analysis on the correlation between the chlorophyll content and the TN content in single cotton leaves in canopy growing under the irrigation with different water volumes is carried out. The results show that there is a significant positive correlation between the chlorophyll content and the TN content (R = 0.8723, n = 39), and the data of chlorophyll content can be used to estimate the TN content in single cotton leaves; the correlation between the integral area variable of red edge and the TN content in cotton leaves in canopy is significant, their correlation coefficient is 0.7394 (n = 40), the TN contents in canopy leaves of cotton varieties named as Xinluzao No. 6 and No. 8 can be accurately estimated by using the developed model, and their RMSE values are 0.3859 and 0.4272 respectively. After researching, it is considered that there is an applying potential to use the integral area variables of red edge for estimating the TN content in cotton leaves in canopy, and the mathematical model developed with the third-side area variables has a high applying value in deriving the TN content in crop canopy. It is also considered that it is feasible to recognize the moisture stress suffered by cotton plants by researching the shift and change extent of red edge, and the key is to develop the corresponding rational recognition index system.
