“…On the contrary, the decreasing trend of Cd accumulation with significantly decreased BCF and TF values was observed in chickpea ( Cicer arietinum ) plants treated with JA and gibberellic acid (GA3) alone and/or in combination 70 . It has also been proven that exogenously JA treatment can disrupt the absorption, transport (root-to-shoot), and accumulation of HMs by suppressing the transporter genes involved in the absorption of HMs by root from soil such as As ( Lsi1 , Lsi2, and Lsi6 genes) and Cd ( AtHMA4 and AtHMA2 genes), as well as transporter genes related to HMs xylem loading such as Cd ( AtIRT1 gene), in plants 71 . As indicated by our results, in the existence of SA and JA, the BCF value had an increasing trend compared to the BCF of plants exposed to 400 µM Ni alone in plants under high Ni concentration.…”

This study investigates Ni phytoremediation and accumulation potential in the presence of salicylic acid (SA) (0, 50 and 200 μM) and jasmonic acid (JA) (0, 5 and 10 μM) in two populations of Alyssum inflatum under various nickel (Ni) doses (0, 100 and 400 μM). By measuring Ni levels in the shoots and roots, values of bioaccumulation coefficient (BAC), biological concentration factor (BCF) and translocation factor (TF) were calculated to quantify Ni accumulation and translocation between plant organs. Additionally, the amounts of histidine (His), citric acid (CA) and malic acid (MA) were explored. The results showed that plant dry weight (DW) [in shoot (29.8%, 8.74%) and in root (21.6%, 24.4%)] and chlorophyll [a (17.1%, 32.5%), b (10.1%, 30.9%)] declined in M and NM populations respectively, when exposed to Ni (400 μM). Conversely, the levels of MA [in shoot (37.0%, 32.0%) and in root (25.5%, 21.2%)], CA [in shoot (17.0%, 10.0%) and in root (47.9%, 37.2%)] and His [in shoot (by 1.59- and 1.34-fold) and in root (by 1.24- and 1.18-fold)] increased. Also, in the presence 400 μM Ni, the highest accumulation of Ni was observed in shoots of M (1392 μg/g DW) and NM (1382 μg/g DW). However, the application of SA and JA (especially in Ni 400 μM + SA 200 μM + JA 5 and 10 μM treatments) mitigated the harmful impact of Ni on physiological parameters. Also, a decreasing trend was observed in the contents of MA, CA, and His. The reduction of these compounds as important chelators of Ni caused a decrease in root-to-shoot Ni transfer and reducing accumulation in the shoots of both populations. The values of phytoremediation indices in both populations exposed to Ni (400 μM) were above one. In presence of the SA and JA, these indices showed a decreasing trend, although the values remained above one (BAC, BCF and TF > 1). Overall, the results indicated that SA and JA can reduce phytoremediation potential of the two populations through different mechanisms.

The availability of nickel (Ni) in root environment and its absorption by plants is a serious concern for plant products and human health. In stressful conditions, phytohormones such as salicylic acid (SA) and jasmonic acid (JA) play an essential role in modulating the physio-biochemical processes of plants. The current study was conducted to investigate Ni phytoremediation and accumulation potential in the presence of SA (0, 50 and 200 µM) and JA (0, 5 and 10 µM) in two populations of Alyssum inflatum, as a Ni-hyperaccumulator plant, under various Ni doses (0, 100 and 400 µM). Accordingly, by measuring Ni levels in shoot and root, values of bioaccumulation coefficient (BAC), biological concentration factor (BCF) and translocation factor (TF) were calculated to quantify Ni accumulation and translocation between plant organs. Furthermore, the amount of histidine (His), citric acid (CA) and malic acid (MA) as important chelators of Ni in shoots and roots were explored. The results displayed that plant mass and chlorophyll content declined in plants under high Ni concentration, while the amount of MA, CA and His increased. However, SA and JA moderated the harmful impact of Ni on physiological parameters and reduced organic acids and His contents in both populations. The values of phytoremediation indexes in both populations exposed to Ni (400 µM) were above one. In presence of the SA and JA, a decreasing trend was observed in these indexes. Overall, the results indicated that SA and JA could reduce phytoremediation potential in the two populations through different mechanisms.

“…The high stomatal density of JA-deficient mutants could be rescued by exogenous NaHS treatment. Apart from that, JA stimulates H 2 S generation to improve physiological adaptation to heavy-metal exposure, probably by initiating CDPK signaling [113]. The interaction between H 2 S and JA under various stress conditions has been extensively reviewed by Li et al [114].…”

Sulfur (S), one of the crucial macronutrients, plays a pivotal role in fundamental plant processes and the regulation of diverse metabolic pathways. Additionally, it has a major function in plant protection against adverse conditions by enhancing tolerance, often interacting with other molecules to counteract stresses. Despite its significance, a thorough comprehension of how plants regulate S nutrition and particularly the involvement of phytohormones in this process remains elusive. Phytohormone signaling pathways crosstalk to modulate growth and developmental programs in a multifactorial manner. Additionally, S availability regulates the growth and development of plants through molecular mechanisms intertwined with phytohormone signaling pathways. Conversely, many phytohormones influence or alter S metabolism within interconnected pathways. S metabolism is closely associated with phytohormones such as abscisic acid (ABA), auxin (AUX), brassinosteroids (BR), cytokinins (CK), ethylene (ET), gibberellic acid (GA), jasmonic acid (JA), salicylic acid (SA), and strigolactones (SL). This review provides a summary of the research concerning the impact of phytohormones on S metabolism and, conversely, how S availability affects hormonal signaling. Although numerous molecular details are yet to be fully understood, several core signaling components have been identified at the crossroads of S and major phytohormonal pathways.
