Introduction In this study, we evaluated the antimicrobial potential of cultivable endophytic fungi associated with Hancornia speciosa Gomes stem bark. Methods and Materials Plant samples were collected in rainy (July 2010) and dry (January 2011) seasons. In total, 116 endophytic fungi strains were isolated from 90 fragments (64.4% frequency of colonization). Higher fungi frequency was observ...

817 configuration.A similar meiotic structure occurs in a few disparate organisms, such as evening primrose and termite, but it has not been seen before in vertebrates. Grützner and colleagues have created fluorescent ‘paints’ for individual platypus chromosomes. By tagging the chromosomes in this manner, they could determine the number of copies of each chromosome in males and females,and thei...

Methods for the effective production of plant secondary metabolites with antitumor activity using plant cell and tissue cultures were developed. The factors in tannin productivity were investigated using culture strains producing different types of hydrolyzable tannins, i.e., gallotannins (mixture of galloylglucoses), ellagi-, and dehydroellagitannins. Production of ellagi- and dehydroellagitan...

Oenothera speciosa Nutt. is a non-indigenous plant that widespread in Europe, South America, Asia, and Oceania. Although its native range it rarely pollinated by sphingid moths, Europe was found to be associated with the hummingbird hawkmoth Macroglossum stellatarum (Linnaeus, 1758). However, plant–insect interaction negative, moths were proboscides stuck flowers of this plant. This relevant co...

Genic allozyme polymorphism and heterozygosity was studied in a large population of the evening primrose, Oenothera biennis, growing in North Haven, Connecticut. This species is a permanent structural heterozygote for the entire complement of 14 chromosomes, and is thus capable of accumulating and maintaining genic heterozygosity. A total of 11 protein species were examined, and these were judg...
