Niche-mediated bacterial community composition in continental glacier alluvial valleys under cold and arid environments.

Introduction: Bacteria are an essential component of glacier-fed ecosystems and play a dominant role in driving elemental cycling in the hydrosphere and pedosphere. However, studies of bacterial community composition mechanisms and their potential ecological functions from the alluvial valley of mountain glaciers are extremely scarce under cold and arid environments.

Methods: Here, we analyzed the effects of major physicochemical parameters related to soil on the bacterial community compositions in an alluvial valley of the Laohugou Glacier No.

Soil bacterial communities associated with multi-nutrient cycling under long-term warming in the alpine meadow.

Introduction: The functions of terrestrial ecosystems are mainly maintained by bacteria, as a key component of microorganisms, which actively participate in the nutrient cycling of ecosystems. Currently, there are few studies have been carried out on the bacteria contributing to the soil multi-nutrient cycling in responding to climate warming, which hampers our obtainment of a comprehensive understanding of the ecological function of ecosystems as a whole.

Methods: In this study, the main bacteria taxa contributing to the soil multi-nutrient cycling under the long-term warming in an alpine meadow was determined based onphysichemical properties measurement and high-throughput sequencing, and the potential reasons that warming altered the main bacteria contributing to the soil multi-nutrient cycling were further analyzed.

Phosphorus Shapes Soil Microbial Community Composition and Network Properties During Grassland Expansion Into Shrubs in Tibetan Dry Valleys.

Alpine ecosystem stability and biodiversity of the Tibetan plateau are facing threat from dry valley vegetation uplift expansion, a process which is highly connected to variations in the soil microbial community and soil nutrients. However, the variation of microbial community properties and their relationship to soil nutrients have scarcely been explored in Tibetan dry valleys, which is a gap that hampers understanding the dry valley ecosystem's response to vegetation change. In this study, we sampled grasslands (G), a grass-shrub transition area (T), and shrublands (S) along an uplift expansion gradient and investigated the link between microbial community properties and soil nutrients.

The Photoperiod-Insensitive Allele Promotes Earlier Flowering in Dwarf Plants of Bread Wheat.

The gibberellin-responsive dwarfing gene can significantly reduce plant height without changing seedling vigor and substantially increase ear fertility in bread wheat ( L). However, delays heading date and anthesis date, hindering the use of in wheat improvement. To promote early flowering of the dwarf plants, the photoperiod-insensitive allele was introduced through a cross between Jinmai47 () and Karcagi ().

[Characteristics of CO Flux in a Mature Apple () Orchard Ecosystem on the Loess Plateau].

Apples () in the Loess Plateau region are grown in the largest apple orchards in the world and China, playing an important role in the improvement of the ecological environment. However, there is little research on the scale of the ecological system of the apple orchard in the Loess Plateau region. In this study, the CO flux of a mature apple orchard in the Loess Plateau region was observed using an eddy covariance technique in the Shannxi Province.

Characterizing the transcriptome and microsatellite markers for almond ( L.) using the Illumina sequencing platform.

Background: The almond tree ( Batsch) is an important nut tree grown in subtropical regions that produces nutrient-rich nuts. However, a paucity of genomic information and DNA markers has restricted the development of modern breeding technologies for almond trees.

Results: In this study, almonds were sequenced with Illumina paired-end sequencing technology to obtain transcriptome data and develop simple sequence repeats (SSR) markers.
