Gibberella zeae is one of the most devastating pathogens of barley and wheat in the United States. The fungus also infects noncereal crops, such as potatoes and sugar beets, and the genetic relationships among barley, wheat, potato, and sugar beet isolates indicate high levels of similarity. However, little is known about the toxigenic potential of G. zeae isolates from potatoes and sugar beets...

It is widely accepted that semantic theories should, as far as possible, be compositional. The claim that a theory is compositional, however, lacks bite if lexical and pre-lexical items are allowed to mean diierent things in diierent contexts. The aim of the current paper is to show how two speciic phenomena can be dealt with by relying on combinatorial eeects to infer diierent consequences fro...

The present study was designed to systematically investigate the chemical profile differences between crude Anemarrhenae rhizoma (CAR) and salt-processed Anemarrhenae rhizoma (SAR). Ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS), coupled with multivariate statistical analysis was used for the discrimination of chemical profiles and the i...
