Little is known about genetic variation and geographic patterns of diversity of Acacia koa. We analyzed diversity using laboratory studies of enzymes. Wide samples of koa possess significant variation in six enzyme genes; several genes have alleles in intermediate frequencies. The variable genes have average expected heterozygosity of 0.41; this indicates that koa has significant levels of gene...

The geographical distribution, ecological characteristics, flowering and fruiting times, and pollinating agents of Passiflora alata are considered and related to molecular genetic data gathered simultaneously. The first report on this species in Rio Grande do Sul was made in 1934, only in cultivated gardens. Approximately 20 years later, however, the species was already classified as efferata (...

In a randomized, placebo-controlled double-blind study, neurophysiological methods were used to determine the effects of Neurexan on patients’ psychophysiological con dition. The administration of Neurexan was found to help them to cope better with acute stress situations. The homeopathic combination medication Neurexan consists of the components passionflower (Passiflora incarnata), oats (Aven...

Abstract Passion fruit (Passiflora spp.) yield is limited by several factors, including soil pathogens, such as Rotylenchulus reniformis (the reniform nematode) and Meloidogyne incognita Southern root-knot nematode). Understanding the behavior of different cultivars, within species passion could be important asset to search for sources resistance, therefore effective management phytonematodes. ...

In an Editorial accompanying PLOS Medicine's Special Issue on Advances in Prevention, Treatment and Cure of HIV/AIDS, Guest Editors Steven Deeks, Sharon Lewin, and Linda-Gail Bekker discuss priorities in the field and the content of the issue.

A pheromone is implicated in the trail marking behavior of caterpillars of the nymphalid silverspot butterfly, Dione juno huascuma (Reakirt) (Lepidoptera: Heliconiinae) that feed gregariously on Passiflora (Malpighiales: Passifloraceae) vines in Mexico. Although they mark pathways leading from one feeding site to another with silk, this study shows that the silk was neither adequate nor necessa...
