Puccinellia tenuiflora is an alkaline salt-tolerant monocot found in saline-alkali soil in China. To identify the genes which are determining the higher tolerance of P. tenuiflora compared to bicarbonate sensitive species, we examined the responses of P. tenuiflora and a related bicarbonate-sensitive Poeae plant, Poa annua, to two days of 20 mM NaHCO3 stress by RNA-seq analysis. We obtained 28 ...
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...
Nitrogen is one of the most important limiting factors for plant growth. However, as ammonium is readily converted into ammonia (NH3) when soil pH rises above 8.0, this activity depletes the availability of ammonium (NH4(+)) in alkaline soils, consequently preventing the growth of most plant species. The perennial wild grass Puccinellia tenuiflora is one of a few plants able to grow in soils wi...
Soil salt-alkalinization is a widespread environmental stress that limits crop growth and agricultural productivity. The influence of soil alkalization caused by Na(2)CO(3) on plants is more severe than that of soil salinization. Plants have evolved some unique mechanisms to cope with alkali stress; however, the plant alkaline-responsive signaling and molecular pathways are still unknown. In th...
Salinization has led to the deterioration of ecological environment, affected growth plants, and hindered development agriculture forestry. Arbuscular mycorrhizal (AM) fungi, as important soil microorganisms, play significant physiological roles in promoting plant nutrient absorption improving structure. Puccinellia tenuiflora (Turcz.) Scribn. et Merr. Songnen saline-alkaline grassland was sele...
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...
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...
