“…Chromium (Cr), existing in the form of Cr 3+ and Cr 6+ , is regarded as the second most common HM, both forms have become major environmental pollution sources. In foxtail millet seedlings, Fang H. et al (2014) also reported that the expressions of H 2 S-emission related genes LCD, DCD2, and DES markedly increased during the first 12 h of Cr 6+ exposure following decline at 24 h, while the expression of DCD1 was consistently increased from 0 to 24 h under 10 mM Cr 6+ stress. Additionally, the H 2 S production rate is induced by Cr 6+ stress in dose- and time-dependent manner, and this induction was the most significant with 24 h of 10 mM Cr 6+ treatment (from 0.6 to 1.6 nmol mg -1 protein min -1 ).…”

For a long time, hydrogen sulfide (H2S) has been considered as merely a toxic by product of cell metabolism, but nowadays is emerging as a novel gaseous signal molecule, which participates in seed germination, plant growth and development, as well as the acquisition of stress tolerance including cross-adaptation in plants. Cross-adaptation, widely existing in nature, is the phenomenon in which plants expose to a moderate stress can induce the resistance to other stresses. The mechanism of cross-adaptation is involved in a complex signal network consisting of many second messengers such as Ca2+, abscisic acid, hydrogen peroxide and nitric oxide, as well as their crosstalk. The cross-adaptation signaling is commonly triggered by moderate environmental stress or exogenous application of signal molecules or their donors, which in turn induces cross-adaptation by enhancing antioxidant system activity, accumulating osmolytes, synthesizing heat shock proteins, as well as maintaining ion and nutrient balance. In this review, based on the current knowledge on H2S and cross-adaptation in plant biology, H2S homeostasis in plant cells under normal growth conditions; H2S signaling triggered by abiotic stress; and H2S-induced cross-adaptation to heavy metal, salt, drought, cold, heat, and flooding stress were summarized, and concluded that H2S might be a candidate signal molecule in plant cross-adaptation. In addition, future research direction also has been proposed.

Calcium (Ca 2? )/calmodulin (CaM), a core component of calcium messenger system, is a multiple second messenger that is involved in multiple stress tolerance including heat tolerance in plants, hydrogen sulfide (H 2 S) is fast emerging similar functions, but Ca 2? and H 2 S crosstalk in the acquisition of thermotolerance is not completely understood. In this article, Ca 2? and CaM activated the activity of cysteine desulfhydrase (L-DES), followed by inducing endogenous H 2 S accumulation in tobacco suspension cultured cells, while treatment with Ca 2? chelator ethylene glycol-bis(b-aminoethylether)-N,N,N 0 ,N 0 -tetraacetic acid and CaM antagonists chlorpromazine lowered L-DES activity and H 2 S accumulation. Interestingly, Ca 2? -and CaM-activated L-DES activity and endogenous H 2 S accumulation were eliminated by H 2 S synthesis inhibitors DL-propargylglycine (PAG), aminooxy acetic acid (AOA), potassium pyruvate (PP) and hydroxylamine (HA), and the H 2 S scavenger hypotaurine (HT), indicating that Ca 2? and CaM regulated endogenous H 2 S generation via activating L-DES activity in tobacco cells. Furthermore, H 2 S donor NaHS, Ca 2? and CaM treatment alone significantly improved the thermotolerance of tobacco cells, and heat tolerance induced by Ca 2? and CaM was enhanced by exogenous NaHS, while weakened by PAG, AOA, PP, HA or HT. All above-mentioned results suggest that endogenous H 2 S generated by L-DES was involved, at least partly, in the thermotolerance induced by Ca 2? and CaM in tobacco suspension cell cultures.
