Root exudates released into soil have important functions in mobilizing metal micronutrients and for causing selective enrichment of plant beneficial soil micro-organisms that colonize the rhizosphere. Analysis of plant root exudates typically has involved chromatographic methods that rely on a priori knowledge of which compounds might be present. In the research reported here, the combination ...

Asymbiotic nitrogen-fixing (ANF) bacteria contribute a substantial amount of nitrogen in ecosystems, especially those with low symbiotic fixation (SNF) capability. Degradation alpine grassland is widespread on the Tibetan Plateau and sown has become one main strategies for restoration. However, diversity community structure ANF different types remain unknown. The aim this study was to fill gap....

Sap sucking heteropteran cereal bugs—members of the Eurygaster and Aelia genus—are serious pests wheat. Moreover, they feed on a variety gramineous plant species, including rye, barley, oat, maize, millet. They are widely distributed in European continent. The purpose this review paper is two-fold; it summarizes currently available data biological characteristics, inflicted damage, their distri...

Outbreaks of rice blast have been a threat to the global production of rice. Members of the Magnaporthe grisea species complex cause blast disease on a wide range of gramineous hosts, including cultivated rice and other grass species. Recently, based on phylogenetic analyses and mating tests, isolates from crabgrass were separated from the species complex and named M. grisea. Then other isolate...
