Soil alkalization severely affects crop growth and agricultural productivity. Alkali salts impose ionic, osmotic, and high pH stresses on plants. The alkali tolerance molecular mechanism in roots from halophyte Puccinellia tenuiflora is still unclear. Here, the changes associated with Na2CO3 tolerance in P. tenuiflora roots were assessed using physiological and iTRAQ-based quantitative proteomi...

Organisms with different life histories are able to act as indicators of characteristics their environment. Here, we compared the precision habitat indication by vegetation and soil microbial communities in four salt-affected pastures: annual open salt sward, Pannonic Puccinellia limosa hollow, Artemisia saline puszta grassy puszta. Dissimilarity habitats was evaluated standardized principal co...

BACKGROUND An efficient transformation method is lacking for most non-model plant species to test gene function. Therefore, subcellular localization of proteins of interest from non-model plants is mainly carried out through transient transformation in homologous cells or in heterologous cells from model species such as Arabidopsis. Although analysis of expression patterns in model organisms li...

Puccinellia tenuiflora is a monocotyledonous halophyte that is able to survive in extreme saline soil environments at an alkaline pH range of 9-10. In this study, we transformed full-length cDNAs of P. tenuiflora into Saccharomyces cerevisiae by using the full-length cDNA over-expressing gene-hunting system to identify novel salt-tolerance genes. In all, 32 yeast clones overexpressing P. tenuif...

The effects of drip irrigation and different cultivation methods on seedgermination and growth of Puccinellia tenuiflora in saline-sodic soils wereinvestigated in field experiments during 2008-2010 in the Songnen Plain, China.Drip irrigation was applied to waste saline-sodic P. tenuiflora grasslands for bothflat and ridge cultivation methods. Drip irrigation affected the distributions ofelectri...

1 Plant and microbial nitrogen (N) dynamics were examined in soils of an Arctic salt marsh beneath goose-grazed swards and in degraded soils. The degraded soils are the outcome of intensive destructive foraging by geese, which results in vegetation loss and near-irreversible changes in soil properties. The objective of the study was to determine whether vegetation loss led to a decline in micro...
