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 grass hosts in subfamily Pooideae. Based on morphological characters and a multigene phylogenetic analysis of the ITS region rDNA, eukaryotic translation elongation factor 1 alpha and a region of the second largest subunit of RNA polymerase II including a putative intein, the Puccinellia bunt is genetically distinct from known species of Tilletia and is proposed as a new species, T. puccinelliae.

There is still a need to investigate the relationships between glycophytes and halophytes and the many biotic and abiotic factors in their natural environments. Therefore, we study the effects of the type of environment on the ecophysiological responses and condition of the glycophyte Elder L., the macrophyte Common Reed (Cav.

Introduction: Despite the wealth of studies dealing with the invasions of alien plants, invasions of alien genotypes of native species (cryptic invasions) have been vastly neglected. The impact of cryptic invasions on the biodiversity of plant communities can, however, be significant. Inland saline habitats and halophytes (i.

Soil salinization and heavy metal (HM) pollution are global environmental problems. Bioorganic fertilizers facilitate phytoremediation, but their roles and microbial mechanisms in natural HM-contaminated saline soils have not been explored. Therefore, greenhouse pot trials were conducted with three treatments: control (CK), manure bioorganic fertilizer (MOF), and lignite bioorganic fertilizer (LOF).

Plants pretreatment with various chemicals has often been used to diminish salinity stress impact on plants. An experiment was carried out to determine the effect of foliar spray of two commercially available biostimulants (Algabon [0.5 g/l] and Bonamid [2 g/l]) on the growth and tolerance of halophytic grass, under non-salinity condition (NSC) and salinity condition (SC).
