Microsatellite primers were developed and optimized for Lippia alba to characterize the L. alba germplasm bank of Universidade de São Paulo. A genomic library enabled the design of 9 microsatellite primers. Six of the 9 primers yielded polymorphic products, which defined 2 groups in the bank. The data provide support to characterize germplasm banks, genetic breeding programs for L. alba, and ot...

Alba-domain proteins are RNA-binding proteins found in archaea and eukaryotes and recently studied in protozoan parasites where they play a role in the regulation of virulence factors and stage-specific proteins. This work describes in silico structural characterization, cellular localization and biochemical analyses of Alba-domain proteins in Leishmania infantum. We show that in contrast to ot...

in order to study the qualitative, quantitative characteristics of a pure common populus alba stand in polkalleh & a mixed stand of populus alba & populus nigra in karchegan, two 30-year-old stands were selected with a plantation interval ( spacing) of 2.5 × 1.5 m in each of which 30 pcs of 2 are samples were randomly selected. in each sample pc all the trees diameters were measured using a dia...

With the aim of increasing the knowledge about endophytic fungi, a group of microorganisms with high biotechnological potential and a valuable source of useful metabolites, a survey in leaves of mangrove plants (Avicennia schaueriana, Laguncularia racemosa, and Rhizophora mangle) was performed at the Itamaracá Island, PE, Brazil. Leaves were collected, during two seasons, dry and rainy, superfi...

BACKGROUND Deforestation is one of the most ubiquitous forms of land degradation worldwide. Although remote sensing and aerial photographs can supply valuable information on land/use cover changes, they may not regularly be available for some tropical coasts (e.g., Cameroon estuary) where cloud cover is frequent. With respect to mangroves, researchers are now employing local knowledge as an alt...

The exotic shrub Lonicera tatarica (Tartarian honeysuckle) has aggressively invaded woodlands and forests in central and eastern North America; however, its impacts on native plant species are not well understood. We used a greenhouse seedling experiment to examine the effects of L. tatarica on Quercus alba (white oak), the presettlement dominant tree of many of these forests. Growthrelated par...

Defatted meals and protein concentrates from six accessions of Sinapis alba and one accession of Brassica juncea mustard seeds were analysed for their polypeptide profile and functional properties. Two types of protein concentrates were prepared using acid-induced and calcium-induced protein precipitations. Meals from the S alba seeds had similar polypeptide composition, which was different fro...

The albA gene of Klebsiella oxytoca encodes a protein of 221 amino acids that binds the albicidin phytotoxin with a high affinity (dissociation constant = 6.4 x 10(-8) M). For this study, circular dichroism (CD) spectrometry and an alanine scanning mutagenesis approach were used in combination to investigate the molecular and conformational mechanisms of this high-affinity protein-ligand intera...

Plant community composition can impact ecosystem processes via litter feedbacks. Species variation in litter quality may generate diff erent patterns of nutrient supply for plants that are dependent on litter inputs. However, it is not known whether plants grow faster in their own litter, litter from other species, or in litter mixtures from multiple species. To test whether litter identity and...
