Cadmium ions influence on the content of anthocyanins as non-plastid pigments and the activity of phenylalanine ammonia-lyase (EC 4.3.1.24) T he increasing of anthropo-technological load [1] is accompanied with environmental accumulation of cadmium compounds, one of the most common first class toxicity pollutants [2]. This statement necessitates the research of its toxic effect mechanisms on plant organisms and determination of the physiological and biochemical adaptive changes in plant cell metabolism [3,4].Plants resistance ability to the high environmental concentrations of cadmium depends on: plant genotype, stage of development and metal concentration, and it is achieved by activation of the induced resistance mechanisms [5]. The support of antioxidant status appropriate level and plant cell ability to the cadmium ions chelation are considered as one of the main intracellular mechanisms of plant resistance to toxic cadmium effect [6]. Such properties are inhe rent in endogenous low molecular weight phenolic metabolites -anthocyanins that play a significant role in the formation of plant adaptive mechanisms to adverse environmental conditions [6,7]. Anthocyanins are also important low molecular weight component of the plant antioxidant system. They show both direct and indirect antioxidant action associated with chelation of metal ions with variable valence [8]. Therefore, plant organism is characteri zed by the increase of phenylpropanoid biosynthesis intensity under the influence of stress factors, and their accumulation level serves as a nonspecific indicator of plant stability [9,10]. Phenylalanine ammonia-lyase (PAL, L-Phenylalanine Ammonia-Lyase EC 4.3.1.24) is a regulatory enzyme of the seconda ry metabolism compound biosynthesis that cataly zes the primary reaction of reverse deamination of L-phenylalanine amino acid to the trans-cinnamic acid [11,12]. Therefore the PAL in the plant orga nism can play an extremely important role to run the resistance mechanisms against the toxic effects of stress factors, including cadmium [10,13].It is known that lettuce (Lactuca sativa L.) and other leafy vegetables being dietary multivitamin daily cultures of human nutrition [14] with a rapid biomass growth could be considered as potential heavy-metal accumulators [15,16].

“…Cd tolerance index, as one of the main integral indicators of plant resistance [24,25], was determined by the formula: TI = Dry weight (+ 0.1 mmol Cd 2+ )/Dry weight (control) × 100% [26,27]. Statistical analysis of the results obtained was carried out with three biological and analytical replicates.…”

“…SB7 ( Salix babylonica ), SM29 ( Salix matsudana ), and SM30 ( S. matsudana ) are elite genotypes of willows with high biomass production; J9‐6 ( Salix integra × Salix suchowensis ) is a shrub willow hybrid; J194 ([ S. matsudana × Salix chosenia arbutifolia ] × S. matsudana ), J799 ( S. matsudana × Salix alba ), J842 ( S. babylonica × S. alba ), and J903 ([ S. matsudana × S. chosenia arbutifolia ] × S. matsudana ) are tree willow hybrids. The genotypes were selected for their high biomass, tolerance to Fe and Mn exposure, and resistance to multiple abiotic stresses such as flooding (Yang et al , ).…”

“…Numerous studies have indicated that willows ( Salix spp.) can accumulate heavy metals (e.g., Cd, Cu, Zn, Mn, and Fe) from contaminated soils and water into their shoot tissues (Shanahan et al ; Yang et al ; Yang et al , , ). Willows are suitable for phytofiltration because of their multiple advantages such as rapid plant growth, vigorous root system, high transpiration capacity, fast nutrient uptake, and high flooding tolerance (Kuzovkina and Volk ; Pistocchi et al ).…”

“…These species provide a rich resource to screen suitable Salix genotypes for improving phytoremediation efficiency of contaminated groundwater. Recent studies have shown that the removal efficiency of Fe and Mn by willows is dependent on the selection of suitable genotypes (Yang et al , ). Selecting Salix genotypes with a wide range of tolerance to the target metals is critical to enhance phytoremediation efficiency, as is a high accumulation capacity of metals (Aasamaa et al ).…”

Groundwater contamination with iron (Fe) and manganese (Mn) is directly related to drink water safety. It remains challenging to simultaneously remove Fe and Mn from groundwater by conventional physical and chemical methods. Willows (Salix spp.) show promise for co‐phytofiltration of Mn and Fe from groundwater. Here, a floating culture system was developed using willows for co‐phytofiltration of Mn and Fe from simulated groundwater. Genotypic differences of willows were evaluated in terms of their tolerance to and accumulation of a mixture of Fe and Mn. The results showed that the growth responses of eight genotypes significantly differed to a mixture of Fe and Mn, ranging from growth inhibition to enhancement. Tolerance index analysis further indicated wide variation in the responses of willows. Tissue‐specific analysis also revealed genotypic variation in the capacity of willows for translocation and accumulation of Fe and Mn. Compared with other genotypes, SB7 (Salix babylonica) and J842 (S. babylonica × Salix alba) demonstrated higher co‐phytofiltration potentials for Fe and Mn based on tolerance, tissue metal concentrations, and shoot metal contents. Thus, both SB7 and J842 are candidates for co‐phytofiltration of Fe and Mn from groundwater.
