“…Many studies have reported that Cd has a negative effect on the leaf area, chlorophyll content [30] [44], lamina and mesophyll thickness, and epidermal cell size [45]. Transpiration plays an important role in the mass flow, and thus Cd translocation to the shoots of Brassica juncea [9] and Impatiens walleriana [46].…”

Cadmium (Cd) is a non-essential element that is highly mobile within organisms where, following plant uptake, subcellular distribution plays an important role in plant tolerance and detoxification. Cd uptake and subcellular distribution were studied in two paddy rice varieties (Japonica and Indica) hydroponically cultivated in Cd-containing solutions. Japonica rice grains containing Cd were also collected from a Cd-contaminated site and subjected to various cooking treatments (boiled, stir-fried, steamed, and control) to determine the influence of cooking method on the subcellular distribution of Cd. Cd treatment inhibited both shoot height and root length, especially in Japonica, where for the same Cd treatment, Japonica accumulated more Cd in roots and shoots than Indica. Most of the accumulated Cd (92% -99%) was bound to the cell wall and vacuoles, and decreased in the order: soluble fraction (Fs) > cell wall fraction (Fcw) > organelle fraction (Fco). Subcellular Cd concentrations in rice grains were significantly affected by cooking treatment. The proportion of trophically available Cd decreased with increase in cooking duration and temperature, indicating that consuming steamed and stir-fried rice had a lower Cd exposure risk than consuming boiled rice.

“…Ni toxicity created disorders in metabolic system of plants and quickly inhibited the cell division (Yusuf et al, 2011). It was reported that excess amount of Ni caused chlorosis of plants and leaf necrosis (Assche and Clijsters, 1990; Mcllveen and Negusanti, 1994;Marschner, 1995;Seregin and Kozhevnikova, 2006;Kovacevic et al, 1999). Kovacevic et al (1999) reported that the Ni stress (100 µM NiSO 4 ) reduced the size of vascular bundle, width of epidermal cells and mesophyll thickness in T. aestivum.…”

The shoot length of wheat seedling decreased by 44% under the Ni stress (Gajewska et al, 2006).…”

The ability of plants to tolerate salts is determined by multiple biochemical pathways that facilitate retention and/or acquisition of water, protect chloroplast functions and maintain ion homeostasis. Essential pathways include those that lead to synthesis of osmotically active metabolites, specific proteins and certain free radical enzymes to control ion and water flux and support scavenging of oxygen radicals. No well-defined indicators are available to facilitate the improvement in salinity tolerance of agricultural crops through breeding. If the crop shows distinctive indicators of salt tolerance at the whole plant, tissue or cellular level, selection is the most convenient and practical method. There is therefore a need to determine the underlying biochemical mechanisms of salinity tolerance so as to provide plant breeders with appropriate indicators. In this review, the possibility of using these biochemical characteristics as selection criteria for salt tolerance is discussed.
