Abstract

Eu3+/Tb3+-co-doped CaWO4 phosphors were synthesized by a simple green co-precipitation process. The structure of the samples was investigated by X-ray diffraction. The photoluminescence spectra and fluorescence decay lifetimes of the samples were measured to investigate the luminescence properties. We analyzed the energy transfer process between Eu3+- and Tb3+-doped CaWO4. As the Tb3+ to Eu3+ energy transfer process was confirmed, Eu3+- and Tb3+-co-doped CaWO4 phosphors showed a color-tunable emission from green to red under a 365-nm UV lamp. [ABSTRACT FROM AUTHOR]

Abstract

Precipitation alteration could profoundly affect the plant community structure and ecosystem function in desert grassland. However, the mechanism of ecological response driven by plant community during extreme changes in precipitation remains unclear. To address this uncertainty, we examined the responses of community composition, diversity and production in slope desert grassland of China to precipitation gradient experiment, which included five precipitation treatment levels (i.e., ambient precipitation as a control [0], ±20% and ±40% of ambient precipitation [-40%, -20%, +20% and +40%]). The extreme drought treatment (-40%) significantly reduced aboveground biomass (AGB) and plant growth (e.g. height, coverage and density) across three years, with no significant effect of increased precipitation treatments. This reduction in ecosystem function coincided with the reducing trend in productivity of forbs and grasses. The relative abundance of certain dominant species (Ajania fruticulosa) decreased, whereas the relative abundance of other dominant species (Stipa breviflora) increased; however, the reordering of species abundances under the extreme drought treatment was not confirmed. Meanwhile, species diversity did not change with precipitation treatments. Furthermore, species asynchrony was reduced by the extreme drought. Our results suggested that the decrease of ecosystem function indicated by AGB is mainly governed by plant growth and biomass of functional groups rather than community composition and diversity under precipitation alteration in the desert grassland.

Abstract

The Columbia root-knot nematode (Meloidogyne chitwoodi Golden et al.) is a serious pest that reduces tuber quality of potato (Solanum tuberosum L.) in the U.S. Northwest and other parts of the world. A gene, [R.sub.Mc1(blb), derived from the Mexican wild species Solarium bulbocastanum Dunal, encodes resistance to this pest. An F1 mapping population with >250 individuals generated from an intraspecific cross between resistant and susceptible clones of S. bulbocastanum, SB22 and PT29, respectively, was used for marker screening and genetic linkage analysis. One amplified fragment length polymorphism marker and five sequence tagged site (STS) markers cosegregated with [R.sub.Mc1(blb). The five STS markers were developed from bacterial artificial chromosome (BAC) end sequences of BAC clones that were derived from another wild species, S. demissum Lindl, and contained homologs of resistance gene N against tobacco mosaic virus. These markers were tested on families that were part of the introgression of [R.sub.mc1(blb)] into advanced breeding lines in [BC.sub.5]. The utility of an efficient alternative to greenhouse and field phenotypic screening was demonstrated, The results of this study confirm that molecular markers closely linked to [RM.sub.Mc1(blb)] will assist in a selection program, reducing expense and time involved in root-knot nematode screening.
