• The analysis of metal distribution in Imperata cylindrica, a perennial grass isolated from the banks Tinto River (Iberian Pyritic Belt), an extreme acidic environment with high content metals, has shown remarkable accumulation iron. This property been used to study iron speciation and its among different tissues structures plant. Mössbauer (MS) X-ray diffraction (XRD) were determine species, scanning electron microscopy (SEM) locate biominerals plant tissue structures, energy-dispersive...
AbstractThe latest publications on Sarcocornia taxonomy and phylogeny recognize six taxa in this genus the Iberian Peninsula: S. perennis, fruticosa, alpini, alpini subsp. carinata, hispanica, pruinosa. The present study represents a comprehensive revision of different Western Mediterranean Europe by means morphological, micromorphological phylogenetic internal transcribed spacer (ITS) analysis. Morphological data were studied from samples 113 populations coastal salt marshes inland pans...
The Tinto River (Huelva, Spain) constitutes a complex and singular system characterized by extreme acidity high concentrations of iron other metals (Cu, Co, Mn, Zn, Pb, As) its soils waters. Traditional mining activity the resulting intensive deforestation have eliminated natural vegetation. Communities endemic Erica andevalensis colonize fluvial terraces areas River, from drier to more humid soils, reaching optimum in proximity rivers streams. Concentrations 22 (S, K, Ca, Fe, Ni, Cu, As,...
Abstract This study presents a comprehensive revision of the genus Sarcocornia (Chenopodiaceae) on Iberian Peninsula based macromorphological, micromorphological and phylogenetic data, considering caryological, ecological biogeographical information. Three species have been identified Peninsula: perennis (Miller) A.J. Scott, fruticosa (L.) Scott alpini (Lag.) Rivas-Martínez. Several authors proposed that S. is specific subspecific rank perennis. Fuente, Rufo Sánchez-Mata recently described...
Soda lakes are inhabited by important haloalkaliphilic microbial communities that well adapted to these extreme characteristics. The surface waters of the haloalkaline Mono Lake (California, USA) alkaline but, in contrast its bottom waters, do not present high salinity. We have studied microbiota shoreline sediments using next-generation sequencing techniques. statistical indexes showed Bacteria had a higher richness, diversity, and evenness than Archaea. Seventeen phyla 8 “candidate...
The revalorization of natural resources in food production is increasing, and the effect climate change negatively affecting conventional crops. In recent years, edible halophytes have received more attention due to their ability tolerate a wide range salinities. Thus, use that require less water are strongly adapted high-salinity soil coastal areas can provide sustainable agriculture certain areas. addition, there growing interest study possibilities these species offer as foods excellent...
Many halophytes have great nutritional and functional potential, providing chemical compounds with biological properties. Salicornia patula Duval-Jouve is a common euhalophyte from saline Mediterranean territories (Spain, Portugal, France, Italy). In the present work we quantified for first time bioactive in S. (total phenolic fatty acids), Iberian Peninsula localities: littoral-coastal Tinto River basin areas (southwest Spain, Huelva province), mainland continental (northwest central...
Abstract The relative concentration and distribution of nickel (Ni) in vegetative tissues (leaves, stems trichomes) reproductive organs (seeds) was studied using energy-dispersive X-ray microanalysis (EDXS) scanning electron microscopy (SEM) two previously Ni-hyperaccumulator subspecies Alyssum serpyllifolium Desf. growing naturally ultramafic soils the Iberian Peninsula: A. ssp. lusitanicum Dudley & P. Silva malacitanum Rivas Goday ex G. López. Both taxa showed that Ni accumulates...
Although biomineralization in plants is an important area of research, there very limited information. In this work, we report the location Na, K, Ca, Mg and Fe biominerals Sarcocornia pruinosa (Chenopodiacaeae), a halophyte species growing estuarine Río Tinto, extreme acidic environment. The soils Tinto basin are characterized by slightly pH high concentrations ions. They exposed to Atlantic Ocean tides that contribute increase pH, Na concentrations. aim work was characterize elemental...
A new hexaploid species of Sarcocornia A.J. Scott, S. hispanica, is described from south east territories the Iberian Peninsula as a species. The micro-, macromorphological and cytological features this taxon are given.
