In subtropical southern Brazil, the leaf spot complex, primarily consisting of brown and net-type net blotch, caused by Bipolaris sorokiniana Pyrenophora teres f. teres, respectively, significantly affects barley production. A survey aimed at enhancing our understanding aetiology complex using DNA barcoding techniques for pathogen identification was conducted in state Paraná, Brazil 2021 2022. ...

Abstract Pyrenophora tritici-repentis ( Ptr ), family Pleosporaceae, is a common wheat pathogen in all wheat-growing regions around the globe. It widely studied North America, South and Africa, while data about fungus genetic diversity Europe still insufficient. This study aimed to describe variation of morphological traits toxin production strains collected Latvia Belarus. Twenty-one isolates ...

In estuarine wetlands, the daily periodic tidal activity has a profound effect on plant growth and reproduction. We studied the effects of tidal action on pollination and reproductive allocation of Sagittaria graminea. Results showed that the species had very different reproductive allocation in tidal and non-tidal habitats. In the tidal area, seed production was only 9.7% of that in non-tidal ...
