Drought is a major threat to plant growth in many parts of the world. During periods drought, multiple aspects physiology are negatively affected. For instance, water shortages induce osmotic imbalance, inhibit photosynthesis, decrease nutrient uptake, and increases production reactive oxygen species (ROS). In this context, it necessary develop sustainable strategies for crops that would help mitigate these conditions. previous studies, endophytic Zopfiella erostrata strains were found...
Marchantia polymorpha L. responds to environmental changes using a myriad set of physiological responses, some unique the lineage related lack vascular- and root-system. This study investigates response M. high doses anthracene analysing antioxidant enzymes their relationship with photosynthetic processes, as well transcriptomic response. We found an dose-dependent reducing plant biomass associated alteration ultrastructure 23.6% chloroplasts. Despite reduction in total thallus-chlorophyll...
Polycyclic aromatic hydrocarbons (PAHs) are widespread globally, primarily due to long-term anthropogenic pollution sources. Since PAHs tend accumulate in soil sediments, liverwort plants, such as
Myrmecochory or seed dispersal by ants is often described as a diffuse mutualism, because many of the ant species that function partners are considered to be similar in terms frequency and consequences their interactions. In this work, we test assumption conducting community surveys removal experiments six study sites located within semi-arid region northwest Argentina. At each site, characterized assemblage interacted with seeds Jatropha excisa Griseb. (Euphorbiaceae), an ant-dispersed...
Abstract The potential explosive seed dispersal under controlled conditions and the by ants in natural populations are compared between two diplochoric species: Jatropha hieronymi Kuntze J. excisa Griseb. seeds of more than eightfold heavier seeds, were explosively dispersed considerably further distances, reaching a maximum almost 18 m. differences distances species seem to depend on both carpel wall thickness fruit aerodynamic shape seed. Seed removal was positively correlated with...
Different fungal isolates closely related to Zopfiella erostrata and Cercophora caudata have been found colonise plant root tissues in an asymptomatic way the Monte Desert biome of La Rioja Province, Argentina. This interaction has newly discovered, role these fungi their desert habitat never studied detail. The objective this study was evaluate eight by means specific physiological traits that could implications for with host plant. selected isolates, four endophytic rhizospheric, were...
Jatropha peiranoi is a plant native to the Monte Desert of Northwest Argentina, where harsh arid conditions prevail. In this work we describe for first time fruit yield and seed oil characteristics wild plants, in order evaluate its potential as biodiesel source. The seeds showed considerable high content, averaging 47% total mass, concentration unsaturated fatty acids, mainly linoleic oleic acids (66% 18%, respectively). Our results show that, though J. has an oilseed crop especially...
La Rioja province annually produces approximately 75,000 tons of agricultural residues and derived materials from agro-industrial activities, which could potentially be incorporated into oyster mushroom cultivation. This study aimed to evaluate the viability this lignocellulosic biomass as a substrate for cultivation edible mushrooms belonging genus Pleurotus. Initially, mycelial growth two species (P. ostreatus P. djamor) was assessed by formulating combinations local substrates....
Large amounts of lignocellulosic residual biomass are generated annually in La Rioja province (Argentina). We have performed a survey to identify crop residues and agro-industrial by-products the province, which could be suitable for oyster mushroom culture. characterized their morphological composition estimated proxy mass that is by each them. also evaluated availability assessing processing, distribution, seasonality, cost other common uses may compete with its application as substrate....
