petroleum contamination of soil is a serious problem throughout the oil producer countries. vegetation may play an important role in the biodegradation of toxic organic chemicals in soil. for petroleum compounds, the presence of rhizosphere micro flora may accelerate biodegradation of the contaminants. in a greenhouse study, petroleum contaminated soil were treated using phytoremediation . the ...

Accurate identification of Arctic plant species is critical for understanding potential climate-induced changes in their diversity and distributions. To facilitate rapid identification we generated DNA barcodes for the core plastid barcode loci (rbcL and matK) for 490 vascular plant species, representing nearly half of the Canadian Arctic flora and 93% of the flora of the Canadian Arctic Archip...

A shipment of Fults alkaligrass seed (Puccinellia distans) grown in Washington state containing bunted florets was intercepted by quarantine officials at China's Tianjin Entry-Exit Quarantine and Inspection Bureau. The bunted florets were filled with irregularly shaped, reticulately ornamented teliospores that germinated in a manner characteristic of systemically infecting Tilletia spp. on gras...

The grass Puccinellia maritima is an important saltmarsh ecosystem engineer exhibiting wide morphological variation, which is partially genetically determined. Nevertheless, nothing is known about its population genetics or how neutral genetic variation is distributed throughout its geographical range. Here, we describe 12 polymorphic microsatellites pooled into two multiplexes for this octoplo...

Many halophytes and halophilic microorganisms are capable to adapt to the extremities of saline habitats. This study reveals the taxonomic diversity and ecological tolerance of bacteria isolated from the rhizosphere of three different halophytes (Bolboschoenus maritimus, Puccinellia limosa and Aster tripolium) living in the vicinity of Kiskunság soda ponds. Following a sampling in September 201...
