Angiosperms and their flowers have greatly diversified into an overwhelming array of forms in the past 135 million years. Diversification was shaped by changes in climate and the biological environment (vegetation, interaction with other organisms) and by internal structural constraints and potentials. This review focuses on the development and structural diversity of flowers and structural con...
Herein, we describe 34 microsatellite loci developed using an enrichment genomic library for the tree species Hancornia speciosa Gomes (Apocynaceae). Thirty-five individuals were genotyped using 34 primers to analyze the polymorphisms at each locus. The number of alleles per locus ranged from 4 to 20. The average number of alleles was 8.11, and the expected heterozygosity ranged from 0.62 to 0....
The bushhopper Phymateus leprosus (Fabricius) in the field shows a special appetite for the milkweed Asclepias fruticosa. Asclepiadaceae, like Apocynaceae and Scrophulariaceae, contain cardiac glycosides. Raw and purified extracts of these plants phagostimulate larval and adult P. leprosus. We also screened natural and half-synthetic compounds found in those plant extracts. While saponins and s...
