Societal Impact Statement Society anticipates a world in which more food and fiber must be produced at warmer temperatures, which, on the contrary, have greater constraints use of water fertilizers. Tree legumes are often climax vegetation semi‐arid arid lands, covering ~25% planet, but knowledge their genomes is limited. A draft genome sequence for Prosopis alba , salt heat tolerant tree that able to fix nitrogen under harsh conditions, yields new clues about its adaptations. Its rich...
Prosopis represents a valuable forest resource in arid and semiarid regions. Management of promising species requires information about genetic parameters, mainly the heritability (h(2)) quantitative profitable traits. This parameter is traditionally estimated from progeny tests or half-sib analysis conducted experimental stands. Such an approach estimates h(2) ratio between-family/total phenotypic variance. These analyses are difficult to apply natural populations with long life cycle,...
There is limited information about seedlings technology production of Prosopis alba ("algarrobo blanco" tree), a native species commercial importance in Argentina.Therefore, the objective this present work was to evaluate effect different substrates and containers on P. growth two nurseries with contrasting environmental conditions.Composted pine bark soil (CPT) composted bark, perlite vermiculite (CPV) mixtures were tested 10 types heights volumes.For each combination substrate container,...
Prosopis alba seedlings, that grew at the 45 dS m−1 salinity level in a previous study of growth and survival Argentine Peruvian Prosopis, were propagated by rooting cuttings established seed orchard/long term evaluation trial on soils with low (EC 5.1–7.5 m−1) but high pH (8.9 to 10.2). A gradient occurred field values ranging from 9.4 block 1 10.3 5. After five years growth, almost all clones had mean height greater than 4 m one clone was more 5 m. Ten 21 tested significantly biomass three...
The identification of factors that structure intraspecific diversity is particular interest for biological conservation and restoration ecology. All rangelands in Argentina are currently experiencing some form deterioration or desertification. Acacia aroma a multipurpose species widely distributed throughout this country. In study, we used the AFLP technique to study genetic diversity, population structure, fine-scale spatial 170 individuals belonging 6 natural Argentinean populations. With...
Abstract In a previous article, growth and survival of Argentine Peruvian Prosopis were measured in greenhouse hydroponic system which the salinities increased from 10 to 45 dS m−1. Twenty-one alba seedlings that grew at m−1 salinity propagated by rooting cuttings seed orchard/long-term evaluation trial established. To develop predictors and/or correlations between seedling performance mature field trials, this study characterized for growth, leaf, thorn morphology ease asexual propagation...
PREMISE OF THE STUDY: Gene flow through dispersal of seeds and pollen is a fundamental determinant spatial genetic structure (SGS) in natural populations trees at different scales. Within continuous populations, restrictions to gene should be manifested process local differentiation, known as isolation by distance. The present work examines the SGS Prosopis alba population patchy region where urban, forest, agricultural areas coexist. analysis discussed here expands our knowledge about...
Abstract Economically and ecologically important quantitative traits of Acacia aroma are related to life history the size shape fruits leaves. Substantial variation is observed for these in natural populations, suggesting a possible genetic basis that could be useful selection programmes. Our objective was detect signals on 12 phenotypic 170 individuals belonging seven populations A. Chaco Region Argentina. Phenotypic were compared with molecular markers assessed same populations. Here, we...
Ants have been widely used as bioindicators of natural and disturbed environments. In Argentine Chaco Seco, ants represent an important part the total biodiversity fulfil various functions in forest ecosystems. With aim evaluating β diversity identifying indicator ants, surveys were carried out three types implanted forests: Neltuma alba (mesquite), Eucalyptus tereticornis (eucalyptus) mixed forests without intervention for 50 years, mainly composed Ceiba speciosa Phoenix canariensis,...
Background and aims: There are currently no microsatellite markers available for any American species of Vachellia, particularly, V. aroma. Then the aims this study were to develop SSR specific aroma, first time, test its amplification in a close related species. M&M: For development total genomic DNA was extracted it sequenced one-fourth run on Roche 454 GS FLX+ platform. The area included two Argentinean populations: San José Robles, Santiago del Estero province. Results: We detected...
