The genus Lippia (Verbenaceae) comprise around 160 species spread out mainly in South and Central Americas with few African species, some of them with potential medicinal use. Brazil is one the most important centers of diversity with approximately 75% of the species described so far. Innumerous species are endemic and poorly studied especially at a cytological level. Here, chromosomal length, ...

PREMISE OF THE STUDY Tithonia diversifolia (Asteraceae) is an invasive plant species that can outcompete natives and thus poses a great threat to biodiversity in introduced areas. Here, expressed sequence tag-simple sequence repeat (EST-SSR) markers were developed and characterized. METHODS AND RESULTS Sixteen polymorphic microsatellite loci were isolated from T. diversifolia using transcript...

A study was designed to compare the color components and color stability of red wine from Noble (Vitis rotundifolia) and Cabernet Sauvignon (Vitis vinifera) at four pH levels (2.8, 3.0, 3.3, 3.8). Noble browned to a much greater extent and lost more color after 10 and 16 months than did Cabernet, and Noble did not increase in chemical age (level of polymeric anthocyanin) to nearly the extent th...
