Differential responses of one hundred tomato genotypes grown under cadmium stress

Abstract: ABSTRACT. Due to increased global concern over the deleterious effects of toxic heavy metals in the environment, it has become necessary to develop plant genotypes that limit the uptake of heavy metals to aerial edible parts. To address this concern, we performed a glasshouse experiment to assess variations within tomato germplasm for cadmium (Cd) tolerance under control conditions and under simulated stress conditions. Significant differences (P < 0.01) were observed among all genotypes at both Cd levels (3 p… Show more

“…Therefore, the data indicated that higher Cd concentrations are not always related to major biomass losses at organ level. This phenomenon can be observed in several tomato accessions under either short-or long-term Cd exposure (Piotto, 2012;Hussain et al, 2015;Alves et al, 2017;Carvalho et al 2018a, b, c). Special cases involve even a better plant performance in the presence of "mild" Cd-induced stress, when compared to the plants cultivated in control conditions (i.e.…”

“…Variations in the Cd toxicity degree were previously observed in different tomato genotypes (Hussain et al, 2015;Carvalho et al, 2018a, b, c;Piotto et al, 2018), but the mechanisms behind the differential tolerance against Cd toxicity are scarcely understood. However, a better understanding about the plant defense mechanisms is crucial for the establishment of strategies to mitigate Cd-induced impacts on crops.…”

“…Different plants have various cadmium accumulation capacities (Yang et al, 1996;Obata and Umebayashi, 1997;Yildiz, 2005). However, variations were also reported among the different cultivars of wheat (Naeem et al, 2016), barley (Tiryakioglu et al, 2006), maize (Ekmekci et al, 2008), soybeans (Shamsi et al, 2008), tomato (Hussain et al, 2015) and chilli peppers (Xin et al, 2013). Kuboi et al (1986) classified Cd accumulation capability of the plants into three groups (high, moderate and low accumulators).…”

“…Tomato (Solanum lycopersicum L.) consumption increases every year due to the fruit attractiveness (many colors, shapes, sizes, and flavors), multiple utilizations (from in natura consumption to processed sauces), and production of therapeutic compounds (Bergougnoux, 2014;FAOSTAT, 2016). However, tomato fruits are a potential pathway for cadmium (Cd) entrance into the food chain (Gratão et al, 2012;Hussain, Saeed, Khan, Javid, & Fatima, 2015;Hussain et al, 2017;Kumar, Edelstein, Cardarelli, Ferri, & Colla, 2015), hence affecting human health by triggering infertility (Alaee, Talaiekhozani, Rezaei, Alaee, & Yousefian, 2014), causing kidney and bone diseases, and increasing cancer risk (Järup & Åkesson, 2009;Nair, Degheselle, Smeets, Van Kerkhove, & Cuypers, 2013). The threshold for Cd concentration in vegetables is set at 0.05 mg/kg (Commission of the European Communities, 2014), but tomato fruits can contain almost twice this limit (Hussain et al, 2015), even when plants are grown in soil with Cd concentrations accepted by the CETESB (i.e., below 3.6 mg/kg, CETESB, 2014).…”

“…Moreover, Cd accumulation in fruits triggers stem‐end yellowing in tomatoes (Kumar et al., ), causing visual damages that may reduce their commercial value. Interestingly, Cd accumulation and its effects on fruit quality, yield, and even progeny fitness depend on tomato cultivars (Carvalho et al., ; Gratão et al., ; Hussain et al., ; Kumar et al., ), indicating a degree of tolerance/sensitivity to this metal. In this context, the use of tomato cultivars with contrasting sensitivity to Cd exposure can be a valuable tool to identify the relation among tolerance mechanisms, Cd accumulation, and fruit quality and yield.…”
