“…To date, the effects of enhancing its synthesis in plants have been described under the action of stressors of various natures [1012]. Also, the effects of increasing plant resistan ce to various adverse influences are shown when treated with gaseous CO or its donors -hematin and hemin [13][14][15]. The action of exogenous CO on plant salt tolerance has been studied only on cultivated grains and some legumes [16][17][18].…”

The role of the gasotransmitter carbon monoxide (Co) in signaling and adaptive processes in plants has been studied insufficiently. There are indirect data indicating jasmonate signaling participation in realization of CO effects, but the possible connection between carbon monoxide and jasmonate signaling during plant adaptation to salt stress remains unclear. We studied the carbon monoxide donor hemin effect on the Arabidopsis of a wild-type (Col-0) and defective in jasmonate signaling coi1 and jin1 mutants response to the salt stress. Arabidopsis thaliana 4-week-old plants were grown on a modified Hoagland's medium. plants were incubated for 24 h in usual or 2 µM hemin containing culture medium, then transferred to 150 mM NaCl containing media and incubated for 24 h before the medium was replaced with the usual one. It was shown that salt stress caused water deficiency and superoxide dismutase and catalase activity decrease in the plants of all three genotypes. Treatment with 2 μM hemin stabilized the levels of catalase activity and photosynthetic pigments and increased guaiacol peroxidase activity in a wild-type, but not in coi1 and jin1 mutant plants after stress induction. Treated with hemin wild-type Arabidopsis plants accumulated more proline and sugars in response to stress than treated coi1 and jin1 mutants. It was concluded that jasmonate signaling can be involved in adaptive processes induced by exogenous carbon monoxide. K e y w o r d s: carbon monoxide, jasmonate signaling, salt resistance, wild type Arabidopsis thaliana, coi1 and jin1 mutants, antioxidant enzymes, pigments, proline.

“…46 On the contrary, hemin was used to induce HO-1 activity, which caused more heme decomposition and more catalytic product production to strengthen the zinc tolerance of rice seedlings. 47 To explore the role of Fe and the relative enzyme HO-1 in the regulatory mechanism of IM enantiomers, ZnPPIX and hemin were used to modulate HO-1 activity. The growth status of wheat seedlings after 3 weeks of culture is shown in Figure 1A.…”

The responses of trace elements and secondary metabolites to stress can reflect plant adaptation to the environment. If and how the imperative trace element Fe and the defensive secondary metabolite 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazine-3(4H)-one (DIMBOA) mediate the toxicity of chiral herbicides to nontarget plants remains inconclusive. We found that the herbicidal-active imazethapyr enantiomer [(R)-IM] stimulated heme oxygenase-1 activity, triggered the release of the catalytic product Fe2+, increased reactive oxygen species production, decreased the DIMBOA content, and increased the DIMBOA–Fe content. XAFS analyses and in vitro Fenton assays demonstrated that DIMBOA could relieve phytotoxicity by chelating excessive Fe3+ to restore Fe homeostasis. The free radical scavenging ability of the chelate of DIMBOA and Fe was also involved. This work refines the dual role of DIMBOA and Fe in mediating the enantioselective phytotoxicity of chiral herbicides, which provides a new direction for improving the herbicide resistance of crops.

“…When the light energy absorbed by LHCII is higher than the energy consumed by PSII, the over-excited energy will damage the photosynthetic organs of the plant, resulting in photoinhibition and photo injury, with PSII being most affected by photoinhibition ( Li et al, 2018 ). Chlorophyll fluorescence can reflect the absorption, transmission, and conversion of light energy by leaves, which plays an essential role in the study of photosynthesis and stress physiology ( Chen et al, 2018 ). Plants absorb light energy for photosynthesis, heat dissipation and fluorescence emission.…”

Cadmium (Cd) stress is one of the principal abiotic stresses that inhibit maize growth. The research was to explore (hemin chloride) Hemin (100 μmol L−1) on photosynthesis, ascorbic acid (AsA)-glutathione (GSH) cycle system, and polyamine metabolism of maize under Cd stress (85 mg L−1) using nutrient solution hydroponics, with Tiannong 9 (Cd tolerant) and Fenghe 6 (Cd sensitive) as experimental materials. The results showed that Hemin can increase leaf photosynthetic pigment content and ameliorate the ratio of Chlorophyll a/chlorophyll b (Chla/Chlb) under Cd stress. The values of ribose 1, 5-diphosphate carboxylase/oxygenase (RuBPcase) and phosphoenolpyruvate carboxylase (PEPCase), and total xanthophyll cycle pool [(violoxanthin (V), antiflavin (A) and zeaxanthin (Z)] increased, which enhancing xanthophyll cycle (DEPS) de-epoxidation, and alleviating stomatal and non-stomatal limitation of leaf photosynthesis. Hemin significantly increased net photosynthetic rate (Pn), stomatal conductance (gs), transpiration rate (Tr), photochemical quenching coefficient (qP), PSII maximum photochemical efficiency (Fv/Fm), and electron transfer rate (ETR), which contributed to the improvement of the PSII photosynthetic system. Compared with Cd stress, Hemin can reduce thiobartolic acid reactant (TBARS) content, superoxide anion radical (O2−) production rate, hydrogen peroxide (H2O2) accumulation, and the extent of electrolyte leakage (EL); decreased the level of malondialdehyde (MDA) content and increased the activities of superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT); slowed the decrease in dehydroascorbic acid reductase (DHAR) and monodehydroascorbate reductase (MDHAR) activity and the increase in glutathione reductase (GR) and ascorbate peroxidase (APX) activity in leaves; promoted the increase in AsA and GSH content, decreased dehydroascorbic acid (DHA) and oxidized glutathione (GSSG), and increased AsA/DHA and GSH/GSSG ratios under Cd stress. Hemin promoted the increase of conjugated and bound polyamine content, and the conversion process speed of free putrescine (Put) to free spermine (Spm) and spermidine (Spd) in maize; decreased polyamine oxidase (PAO) activity and increased diamine oxidase (DAO), arginine decarboxylase (ADC), ornithine decarboxylase (ODC) and S-adenosylmethionine decarboxylase (SAMDC) enzyme activities in leaves under Cd stress.
