The Role of Organic Acids in the Domestication of Oxalis tuberosa: A New Model for Studying Domestication Resulting in Opposing Crop Phenotypes1

Abstract: The Role of Organic Acids in the Domestication of Oxalis tuberosa: A New Model for Studying Domestication Resulting in Opposing Crop Phenotypes. Though few crops display directly opposing domesticated phenotypes, these crops may be the key to understanding domestication processes that address conflicting selective pressures in the agricultural ecosystem. Two relatively well-known examples are cassava (Manihot esculenta Crantz), which has high-cyanide and low-cyanide varieties, and potato (Solanum section Petot… Show more

“…However, there are edible plants not yet commercialized (Arrigo et al, 2011;Bradbury and Emshwiller, 2011;Emshwiller et al, 2009;Sampliner and Miller, 2009). These plants are all around in the local landscapes; they need only to be identified and used.…”

“…Por otra parte, los valores de pH también sufrieron cambios significativos en todas las muestras, esto debido a que durante la exposición a la radiación solar, se produjo una disminución en la concentración de los ácidos orgánicos del alimento [9], pero esto no influyó significativamente en la acidez titulable en la mayoría de las muestras.…”

“…Los productores de oca conocen las ventajas y desventajas de las accesiones locales tanto para su producción, alimentación, usos culinarios e incluso propiedades medicinales [7] ya que pueden distinguir entre las variedades dulces, semidulces y amargas (conocidas como luk'i). Esta última parece poseer mayor concentración de ácido oxálico [9] y oxalatos y por ende sus tubérculos pueden contribuir a la formación de cálculos renales e inducir a la descalcificación de material óseo y se recomienda su consumo moderado en personas que sufren de hiperoxaluria entérica o primaria [10,11].…”

“…Additionally, people's management over time has led to genetic changes, altering plant characteristics (morphology, physiology, phenology, life cycles) according to different human requirements [31]. Examples can include the alterations in the amount of certain compounds [32,33], which can, in turn, have an influence on a plant's taste, nutritional/medicinal use, and toxicity.…”
