“…This might be because the plants enhanced their expression levels to defend against ROS formation caused by the heavy metals. This supports the findings of previous studies (Bashri and Prasad, 2015; Singh et al, 2013). However, the greater inhibition of WT plant growth compared to the RsMYB1 overexpressing plants suggests that the antioxidant inducement in WT plants was significantly lower than in RsMYB1 overexpressing plants.…”

0The RsMYB1 transcription factor (TF) controls the regulation of anthocyanin in radish 1 1 (Raphanus sativus), and its overexpression in tobacco and petunia strongly enhances anthocyanin 1 2 production. However, no data exists on whether RsMYB1 is involved in the mechanism that 1 3 leads to abiotic stress tolerance. Under normal conditions, transgenic petunia plants expressing 1 4 RsMYB1 and WT were able to thrive by producing well-developed broad leaves and regular 1 5 roots. In contrast, a reduction in plant growth was observed when they were exposed to heavy 1 6 metals (CuSO 4 , ZnSO 4 , MnSO 4 , and K 2 Cr 2 O 7 ). However, RsMYB1-overexpressing plants were 1 7 found to be more tolerant to the stresses than the WT plants because the expressions of stress tolerant genes (GSH and PCs) and antioxidant genes (SOD, CAT, and POX) were enhanced. In addition, according to the phylogenetic analysis, RsMYB1 has a strong sequence similarity with 2 0 other MYB TFs that confer different abiotic stresses. These results suggest that overexpression 2 1 of RsMYB1 enhances the expression levels of metal-induced stress tolerance genes and 2 2 .

“…The main components of ID are IAA and DA-6, which can promote the growth of J. curcas at low concentrations and inhibit it at high concentrations. Bashri et al (2015) confirmed that Cd alone and together with high concentrations of IAA can induce oxidative stress, while combinations of Cd and low doses of IAA can decrease it and attenuate Cd toxicity [28]. The toxic effects of Pb and Cd on J. curcas can be increased with applications of high-concentration ID.…”

The effects of indole-acyl esters (ID), NH 4 NO 3 (N), and KH 2 PO 4 (P), on the mitigation of the toxic effects of Cd and Pb and their concentration in Jatropha curcas L. from contaminated soils was investigated. The concentrations of ID, N, and P were optimized (0.1 mL·L -1 , 7 mM, and 2.5 mM, respectively) and they were applied in various combinations to the contaminated soils of potted plants of J. curcas. The results showed that ID together with the N and P fertilizers, increased plant biomass and improved the mitigating effects of the N-P treatments on Cd and Pb toxicity. Plants growing under ID-N-IP treatments had high whole plant biomasses, high concentrations of P, N, Pb and Cd in whole plants, as well as enhanced activities of superoxide dismutase (SOD) and peroxidase (POD). These results point to the phytoremediation ability of J. curcas. We propose a new methodology that can be utilized to study the effects and interactions of multiple factors on plant growth.
