Prescribed burning is a commonly advocated and historical practice for control of woody species encroachment into grasslands on all continents. However, desert grasslands of the southwestern United States often lack needed herbaceous fuel loads for effective prescriptions, dominant perennial graminoids may have poor fire tolerance, and some systems contain fire-tolerant invasive species. We exa...

allergy to prosopis juliflora (mesquite) pollen is one of the common causes of respiratory allergy in tropical countries. mesquite is widely used as street trees in towns and ornamental shade trees in parks and gardens throughout arid and semiarid regions of iran. the inhalation of mesquite pollen and several species of amaranthus/chenopodiaceae family is the most important cause of allergic re...

The extraction of high-quality genomic DNA from Prosopis spp for polymerase chain reaction (PCR) amplification is complicated, owing to the presence of a high percentage of secondary metabolites that bind to or co-precipitate with nucleic acids. In the present study, we report a modified sodium dodecyl sulfate/phenol protocol that eliminates the use of liquid nitrogen in the maceration process,...

Browsing is an important mortality factor in seedlings and small plants. However, the induced changes in the architecture of plant survivors may influence subsequent browsing, opening the possibility of compensating for the damage done. How jackrabbit (Lepus californicus) browsing affects the growth and architecture of small individuals of honey mesquite, Prosopis glandulosa var. torreyana, a t...

The present paper aims to identify the distribution of Microsatellite markers (SSRs)/Single Nucleotide Polymor-phism (SNPs) as resource tools for the analysis of interspecies hypervariability in Prosopis spp. Microsatellites are ubiquitously repeated extension of 1-5 bp motif extended throughout the genome. The dbEST division of Genbank contains 1467 ESTs of Prosopis juliflora which have been u...

The present study investigated the in vitro antiprotozoal activity of sixteen selected medicinal plants. Plant materials were extracted with methanol and screened in vitro against erythrocytic schizonts of Plasmodium falciparum, intracellular amastigotes of Leishmania infantum and Trypanosoma cruzi and free trypomastigotes of T. brucei. Cytotoxic activity was determined against MRC-5 cells to a...

The purpose of this study was to assess the in vitro antimicrobial activity of alkaloid-enriched extracts from Prosopis juliflora (Fabaceae) pods in order to evaluate them as feed additives for ruminants. As only the basic chloroformic extract (BCE), whose main constituents were juliprosopine (juliflorine), prosoflorine and juliprosine, showed Gram-positive antibacterial activity against Microc...

Due to land use change mainly for induced agriculture, Tamaulipan thornscrubin northeast Mexico has been cleared and transformed into small patches of vegetation as small as isolated trees surrounded by agricultural fields. In this study, we explored how tree isolation or growing inside a fragment of remnant vegetation influence diversity of coleopterans in two plant species (Prosopis laevigata...

A list of advantages of this apparatus would be headed by the fact that it can be constructed from the simplest of laboratory equipment. Also, in contrast to the original design, no special tooling is required and no dimensions can be termed critical. The use of all flexible joints eliminates breakage, and the short overall length of the delivery tube makes delivery volumes more accurate and le...

UNLABELLED PREMISE OF THE STUDY As only six useful microsatellite loci that exhibit broad cross-amplification are so far available for Prosopis species, it is necessary to develop a larger number of codominant markers for population genetic studies. Simple sequence repeat (SSR) markers obtained for Prosopis species from a 454 pyrosequencing run were optimized and characterized for studies in...
