Self-sterility in the hexaploid Handroanthus serratifolius (Bignoniaceae), the national flower of Brazil [PDF]

Acta Botânica Brasílica, 2013
Polyploidization is common among angiosperms and might induce typically allogamous plants to become autogamous (self-compatible, relying on sexual self-fertilization) or apomictic (achieving asexual reproduction through seeds).

Veratric Acid and the Cytotoxic Activity of Handroanthus impetiginosus Inner Bark Extract: No Association. [PDF]

Chem Biodivers
Physicochemical characterization, phytochemical profiling, and in vitro cytotoxicity assessment of Handroanthus impetiginosus inner bark extract show that veratric acid, despite being readily identified by HPLC‐DAD, does not account for the observed cytotoxicity.

From fertilizer to insecticide: urban leaf litter chemistry alters the survival landscape of Aedes aegypti. [PDF]

Pest Manag Sci
Chemical profiling and bioassays reveal that leaf‐litter leachates from urban trees flip between nourishing and killing Aedes aegypti larvae: dilute Tipuana tipu boosts growth, whereas concentrated, aged extracts are >90% lethal. Species‐specific chemistry thus turns street trees into potential self‐renewing tools for integrated vector control ...
