Coffee is highly sensitive to temperature and rainfall, making its cultivation vulnerable to geographic shifts in response to a changing climate. This could lead to the establishment of coffee plantations in new areas and potential conflicts with other land covers including natural forest, with consequent implications for biodiversity and ecosystem services. We project areas suitable for future...

The Achillea L. genus has a wide distributional range, and the differences in oil composition may be affected by different environmental factors such as soil mineral fertilization, the climate conditions and the culture site. To evaluate the effect of temperate climate on content and chemical combination of essential oil of Achillea filipendulina Lam,  A. arabica Kotschy and A. eriophora DC., t...

PREMISE OF THE STUDY Expressed sequence tag-simple sequence repeat (EST-SSR) markers were developed using Illumina sequencing for further genetic diversity studies of Stipa purpurea (Poaceae). METHODS AND RESULTS Twenty-nine polymorphic and eight monomorphic EST-SSR loci were developed and characterized in 90 individuals from nine S. purpurea populations. The number of alleles per locus range...

Loss of plant diversity with increased anthropogenic nitrogen (N) deposition in 40 grasslands has occurred globally. In most cases, competitive exclusion driven by preemption of 41 light or space is invoked as a key mechanism. Here, we provide evidence from a 9-year N 42 addition experiment for an alternative mechanism: differential sensitivity of forbs and grasses to 43 increased soil manganes...

Flora and vegetation data of the nature monument regional importance “Elandinsky stones” (Tselinnyy district, Altai Krai) are given. comprises 283 species higher vascular plants, including 2 rare species: Paeonia hybrida, Stipa pennata. Vegetation is represented by petrophyte forb-feathergrass steppe, for Bijsk-Chumysh upland, forb-grasses meadow, birch forests bushes.

β-D-Galactosidase (EC 3.2.1.23) has been detected in several plant species, and is characterized in different organs and tissues by its ability to hydrolyse terminal non-reducing β-D-galactosyl residues from β-D-galactoside polymers. In the present paper the cloning and the biochemical and molecular characterization of Coffea arabica β-galactosidase expressed in the pericarp and the endosperm o...

A new collection of several Red Sea sponges was investigated for the discovery of potential breast cancer migration inhibitors. Extracts of the Verongid sponges Pseudoceratina arabica and Suberea mollis were selected. Bioassay-directed fractionation of both sponges, using the wound-healing assay, resulted into the isolation of several new and known brominated alkaloids. Active fractions of the ...

Of all plant constituents, coffee has one of the highest concentrations of chlorogenic acids. When roasting coffee, some of these are transformed into chlorogenic acid lactones (CGL). We have studied the formation of CGL during the roasting of coffee beans in Coffea arabica cv. Bourbon; C. arabicacv. Longberry; and C. canephora cv. Robusta. Individual CGL levels were determined by comparison of...

Espresso Coffee is a poliphasic beverage which physicochemical and sensory characteristics obviously depend on both the selection of ground roasted coffee and the percolation process technical conditions. The aim of this work was to evaluate the influence of coffee/water ratio on the physicochemical and sensory quality of espresso coffee. Furthermore, the influence of botanical varieties (Arabi...
