Excess manganese differentially inhibits photosystem I versus II in Arabidopsis thaliana
TLDR
The results demonstrate for the first time that PSI is the major target of Mn toxicity within the photosynthetic apparatus of Arabidopsis plants. Expand
Carbon sink limitation and frost tolerance control performance of the tree Kageneckia angustifolia D. Don (Rosaceae) at the treeline in central Chile
TLDR
A confluence of global (carbon sink limitation) and regional (freezing tolerance) mechanisms explains the treeline formation in the Mediterranean-type climate zone of central Chile. Expand
Ecotypic Differentiation in Morphology and Cold Resistance in Populations of Colobanthus quitensis (Caryophyllaceae) from the Andes of Central Chile and the Maritime Antarctic
TLDR
Both Andean and Antarctic plants increased soluble sugars with increasing acclimation time, but it did not differ between populations, and the mechanistic basis of the higher survival to freezing of Antarctic plants was not elucidated. Expand
The antioxidant properties of calafate (Berberis microphylla) fruits from four different locations in southern Chile
Se determino la capacidad antioxidante (CA), antocianinas totales (AT) y fenoles totales (FT) de frutos de calafate de cuatro localidades del sur de Chile (El Blanco, Lonquimay, Manihuales y Temuco)Expand
ANTIOXIDANT COMPOUNDS IN SKIN AND PULP OF FRUITS CHANGE AMONG GENOTYPES AND MATURITY STAGES IN HIGHBUSH BLUEBERRY (Vaccinium corymbosum L.) GROWN IN SOUTHERN CHILE
We evaluated the genotype and maturity effects on antioxidant activity and phenolic compounds of whole, skin and pulp fruits from three highbush blueberry cultivare (cv. Brigitta, cv. Bluegold andExpand
Al 3+ - Ca2+ INTERACTION IN PLANTS GROWING IN ACID SOILS: AL-PHYTOTOXICITY RESPONSE TO CALCAREOUS AMENDMENTS
High aluminum (Al) concentrations as Al3+ represent an important growth and yield limiting factor for crops in acid soils (pH ≤5.5). The most recognized effect of Al-toxicity in plants is observed inExpand
Long-term Aluminum Exposure Effects on Physiological and Biochemical Features of Highbush Blueberry Cultivars
We compared the aluminum tolerance of two highbush blueberry (Vaccinium corymbosum) cultivars, Legacy and Bluegold, grown in a greenhouse in Hoagland's solution with increasing concentrations of AlExpand
Changes during early development in photosynthetic light acclimation capacity explain the shade to sun transition in Nothofagus nitida.
TLDR
During development, N. nitida changes the balance of light energy utilization and photoprotective mechanisms, supporting a phenotypic transition from shade to sun during its early ontogeny. Expand
Seasonal changes in the photosynthetic performance of two evergreen Nothofagus species in south central Chile
TLDR
Los resultados sugieren that bajo condiciones de mayor intensidad luminica, mayor temperatura y sequia, N. dombeyi mostro un mejor desempeno fotosintetico que N. nitida. Expand
Molecular and physiological strategies to increase aluminum resistance in plants
TLDR
Recent findings regarding molecular and physiological mechanisms of Al toxicity and resistance in higher plants are summarized, including genes involved in Al resistance that have been identified and characterized in several plant species. Expand
