“…Common plant seedlings, such as rice, Arabidopsis, and maize, experienced mortality under 0.5 mM Zn stress (Song ZZ, Guo SL, Ma RJ and Yu ML, unpublished results). Despite this, certain plant species, such as Silene vulgaris and Halimione portulacoides, have evolved a tolerance to Zn that enables them to grow in Zn-contaminated soils, remaining unaffected by the elevated Zn levels (Ernst et al, 2000;Cambrollé et al, 2012).…”

“…High doses of Zn in the soil and, consequently, in the tissues, can interfere with the integrity and metabolism of chloroplasts (Cherif et al, 2010;Todeschini et al, 2011). The excess of Zn in the leaves acts mainly on the transport of electrons between photosystems and increases the oxidative stress in chloroplasts, resulting in the degradation of chlorophylls and in the reduction of photosynthesis (Reichman, 2002;Cherif et al, 2010;Cambrollé et al, 2012).…”

“…These alterations result from damages in electron transport efficiency and carbon assimilation, compromising the photosynthetic performance of leaves (Dhir et al, 2008;Cambrollé et al, 2012). In general, Zn excess mainly affects the reaction center of photosystem II (PSII), restricting the expression of the proteins D1 and D2 (Todeschini et al, 2011).…”

“…Moreno et al, 2013;Cambrollé et al, 2012a;Cambrollé et al, 2012b;Sousa et al, 2008). Esta gran tolerancia se debe a los eficientes mecanismos de detoxificación y compartimentalización que presenta esta especie; los metales están principalmente asociados a la pared celular de las células vegetales, lo que actúa de barrera contra los efectos nocivos de los metales al mantenerlos alejados del citoplasma y otros orgánulos intracelulares con actividad metabólica (Sousa et al, 2008).…”

“…Los resultados de este trabajo concuerdan con los de otros estudios previos en los que también se observaron valores de FT de Cu y Zn < 1, con una mayor concentración de metales en las raíces que en la parte aérea de verdolaga, al restringirse la capacidad de translocación siempre que no se supere cierto umbral en el suelo (Andrades- Moreno et al, 2013;Cambrollé et al, 2012a;Cambrollé et al, 2012b;Sousa et al, 2008). Estos autores sugieren que esto se debe a que estas plantas llevan a cabo una estrategia de exclusión de los metales, inmovilizándolos en la pared celular de las células de las raíces.…”
