| 1 | Glutamine analogs promote cytoophidium assembly in human and Drosophila cells显示文摘CTP synthase is compartmentalized within a subcellular structure,termed the cytoophidium,in a range of organisms including bacteria, yeast,fruit fly and rat.Here we show that CTP synthase is also compartmentalized into cytoophidia in human cells.Surprisingly,the occurrence of cytoophidia in human cells increases upon treatment with a glutamine analog 6-diazo-5-oxo-L-norleucine(DON),an inhibitor of glutamine-dependent enzymes including CTP synthase.Experiments in flies confirmed that DON globally promotes cytoophidium assembly.Clonal analysis via CTP synthase RNA interference in somatic cells indicates that CTP synthase expression level is critical for the formation of cytoophidia.Moreover,DON facilitates cytoophidium assembly even when CTP synthase level is low.A second glutamine analog azaserine also promotes cytoophidum formation.Our data demonstrate that glutamine analogs serve as useful tools in the study of cytoophidia. | mr Yilmaz Tastan Zillah Anne Deussen Mayte Yu-Yin Siswick | 2011 | Journal of Genetics and Genomics2011，38，9： | 10 |
| 2 | Nanovesicles Are Secreted during Pollen Germination and Pollen Tube Growth: A Possible Role in Fertilization显示文摘Dear Editor, During recent decades,a novel mechanism of secretion has been identified in a wide range of mammalian cells.It involves the release of bioactive membrane nanovesicles (30-100 nm),termed exosomes,upon the fusion of multivesicular bodies with the plasma membrane (Théry et al.,2009).Exosomes are implicated in diverse functions,such as scavenging of archaic proteins,intercellular messengers delivering cell-specific signals,and vehicles for transmissible pathogens.Exosomes have also been described in other organisms such as bacteria,Drosophila,and fungi. | Noela Prado Juan de Dios Alche Juan Casado-Vela Salvador Mas Mayte Villalba Rosalia Rodriguez Eva Batanero | 2014 | Molecular Plant2014，7，3： | 3 |

| 9 | Anatomical variation of five plant species along an elevation gradient in Mexico City basin within the Trans-Mexican Volcanic Belt, Mexico显示文摘Change in environmental conditions with altitudinal gradients induces morpho-anatomical variations in plants that have been poorly documented in intertropical regions. Five species with three life forms, cryptophyte(Alchemilla procumbens, Geranium seemannii), hemicryptophyte(Acaena elongata, Lupinus montanus), and phanerophyte(Symphoricarpos microphyllus), distributed along an altitudinal gradient in the Sierra Nevada of central Mexico, were studied. The aims were to identify and evaluate their morpho-anatomical modifications under the hypothesis that the sizes of individuals and of their wood and leaf cell types decrease as elevation increases. Three individuals per species per site were collected at seven locations along the altitudinal gradient(2949-3952 m). Their morpho-anatomical characters were analyzed through multiple regression analyses. Elevation was the variable that best explained anatomical changes in the leaf and wood ofthe five species. Canopy density and potassium content in the soil also contributed to explain the variation in anatomical variables along the gradient. As elevation increased a bimodal pattern was observed in various anatomical characters as in the leaf width of A. elongata, A. procumbens and G. seemannii and in the vessel diameter of A. procumbens, G. seemannii, and L. montanus. Other features as the vessel diameter of A. elongata, the fiber length of S. microphyllus, and the ray width of A. elongata increased as the elevation increased. Anatomical traits have a tendency to decrease in size but just toward the end of the gradient, which is probably related to changes in canopy density. The plant response to the altitudinal gradient is more focused on anatomical adaptations than morphological variation; it is also species dependent. | P Mayte S.JIMéNEZ-NORIEGA Teresa TERRAZAS Lauro LóPEZ-MATA Arturo SáNCHEZ-GONZáLEZ Heike VIBRANS | 2017 | Journal of Mountain Science2017，14，11： | 1 |

| 20 | Oxidative Degradation of Thermoplastic Starch Induced by UV Radiation显示文摘Among biopolymers,thermoplastic starch(TPS)is a good candidate to obtain biomaterials because of its natural origin,biodegradable character,and processability.Exposure to ultraviolet(UV)radiation causes significant degradation of starch-based materials,inducing photooxidative reactions which result in breaking of polymer chains,production of free radical,and reduction of molar mass.These changes produce a deterioration of TPS mechanical properties,leading to useless materials after an unpredictable time.In this work,changes induced on TPS by UV radiation,analyzing structural properties and mechanical behavior,are studied.TPS was obtained through thermo-mechanical processing of native corn starch in the presence of water(45%w/w)and glycerol(30%w/w)as plasticizers.Films were obtained by thermocompression and,before testing,specimens were conditioned to reduce material fragility.Photodegradation process was performed by exposing TPS to 264 h UV radiation in a weathering test chamber.Specimen’s weight loss was determined gravimetrically.Chemical changes were studied by Fourier Transform Infrared Spectroscopy(FTIR)and morphological modifications were analyzed by Scanning Electron Microscopy(SEM).Reduction of weight average molar mass was measured by Static Light Scattering(SLS).Changes in mechanical properties were studied from tensile tests.After 96 h exposure,TPS specimens presented a weight reduction of 4-6%,mainly attributed to plasticizers lost by evaporation.SEM observations showed that UV radiation induced morphological changes on TPS,evidenced by an increment of specimens cracking.By FTIR,it was detected the presence of an additional band located at 1726 cm-1 in samples submitted to UV radiation,attributed to the formation of-C=O groups.Weight average molar mass of native starch was in the order of 107 g mol-1.TPS exposure to UV radiation decreased significantly its molar mass,confirming molecular degradation of the biopolymer.When TPS was exposed during 48 h,it was detected a considerable decrease in elongation at break values(~85%),indicating that TPS flexibility was reduced.On the other hand,after 48 h exposure,TPS elastic modulus was 55 times higher than those of the unexposed specimens,evidencing an increase in material rigidity.TPS maximum tensile strength was also increased by UV light,with an increment of^400%after 48 h exposure.Results revealed that starch-based materials can be degraded by exposure to UV radiation,modifying their microstructure and mechanical performance. | Mayte M.Quispe Olivia V.López Marcelo A.Villar | 2019 | Journal of Renewable Materials2019，7，4： | 1 |
