PREMISE OF THE STUDY Simple sequence repeat (SSR) markers were developed for Aster savatieri (Asteraceae) and the serpentine variety A. savatieri var. pygmaeus to re-evaluate their taxonomic status. METHODS AND RESULTS Using RNA-Seq data, 22 expressed sequence tag (EST)-SSR markers were developed. Polymorphisms were assessed in A. savatieri and in A. savatieri var. pygmaeus. The average numbe...

Ethanol extracts of 83 plants species belonging to the Asteraceae (Compositae) family, collected in the State of Minas Gerais, Brazil, were tested for larvicidal activity against the mosquito Aedes fluviatilis--Diptera: Culicidae). The extract from Tagetes minuta was the most active with a LC90 of 1.5 mg/l and LC50 of 1.0 mg/l. This plant has been the object of several studies by other groups a...
