Phytoextraction of Cu, Cd, Zn and As in four shrubs and trees growing on soil contaminated with mining waste
Heredia, Tatiana Belén; Tapia Balmaceda, Raúl Esteban; Young, Brian Jonathan; Hasuoka, Paul; Pacheco, Pablo; Roqueiro, Gonzalo (Elsevier, 2022-12)Mining activity has degraded large extensions of soil and its waste is composed of metals, anthropogenic chemicals, and sterile rocks. The use of native species in the recovery of polluted soils improves the conditions for ... -
Strategies of physiological, morpho-anatomical and biochemical adaptation in seedlings of native species exposed to mining waste
Heredia, Belén; Diaz Recio, Pablo; Young, Brian Jonathan; Pacheco, Pablo; Barcelo Zungre, Franco; Hruby, Silvina Anabela; Acevedo, Maria Andreína; Mercado, María Inés; Roqueiro, Gonzalo (Elsevier, 2025-01-22)Seeds of four native species of trees and shrubs (Larrea cuneifolia, Bulnesia retama, Plectrocarpa tetracantha and Prosopis flexuosa) were exposed to soil contaminated with As, Cu, Cd, and Zn from an abandoned gold mine ... -
Structure, ultrastructure and cation accumulation in quinoa epidermal bladder cell complex under high saline stress
Palacios, María Belén; Rizzo, Alex Joel; Heredia, Tatiana Belén; Roqueiro, Gonzalo; Maldonado, Sara; Murgida, Daniel Horacio; Burrieza, Hernán Pablo (Springer, 2024-01-13)Quinoa is a facultative halophyte with excellent tolerance to salinity. In this study, the epidermal bladder cell complex (EBCc) of quinoa leaves was studied to determine their cellular characteristics and involvement in ... -
Willow seedlings from photooxidized seeds accelerate cotyledon death and anticipate first leaf emergence: a histological and biochemical study following germination
Roqueiro, Gonzalo; Causin, Humberto Fabio; Ollé Resa, Carolina Patricia; Maroder, Horacio; Maldonado, Sara Beatriz (Wiley, 2013-10)In willow seeds, photooxidative damage is mainly restricted to the outer cotyledonary tissues, significantly reducing normal germination. Here we analyzed the damage generated in cotyledonary tissues and investigated whether ...
