The Characeae oospores are frequently found in sediment samples during Quaternary palaecological studies. Counts of oospores of three Estonian Late-glacial (14000 – 11500 calibrated year before present, cal y BP) sediment cores are presented and discussed. The first postglacial findings of Characeae oospores in Estonia date back 13900 cal y BP confirming the early appearance of Characeae in pos...

The phytohormone auxin is one of the main directors of plant growth and development. In higher plants, auxin is generated in apical plant parts and transported from cell-to-cell in a polar fashion. Auxin is present in all plant phyla, and the existence of polar auxin transport (PAT) is well established in land plants. Algae are a group of relatively simple, autotrophic, photosynthetic organisms...

Negative somatic effects such as myocardial infarction and stroke have been reported, though, less frequently.
