“…ROS and NO could exert multiple effects on photosynthetic and mitochondrial metabolisms (5,6). The impact of ROS on photosynthesis was studied by several groups (7,8), while the studies with NO are just catching up (9). Nitric oxide (NO), can modulate various physiological processes in plants (9,10).…”

The reported effects of nitric oxide (NO), a signaling molecule, on the photochemical components of leaves are ambiguous. We examined the changes by a natural NO donor, S-nitrosoglutathione (GSNO). The effect of GSNO on Pisum sativum leaves was studied after a 3-hour exposure in dark, moderate (ML), or high light (HL). The NO levels in GSNO-treated samples were at their maximum under HL, compared to those under ML or dark. Most of the elevated NO was decreased by 2-4-carboxyphenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO), a NO scavenger, confirming the NO increase. Treatment with GSNO caused inhibition of photosynthesis/respiration and restricted electron transport mediated by both photosystem (PS)II and PSI. However, the inhibition by NO-donor of PSII components was stronger than those of PSI. A marked increase in the PSI acceptor side limitation [Y(NA)] and a decrease in PSI donor side limitation [Y(ND)] indicated an upregulation of cyclic electron transport, possibly to balance the damage to PSII by GSNO. We suggest that NO aggravated the HL-induced inhibition of photosynthesis and dark respiration.

“…The NT plants grew well at treatment with 80 mg kg -1 of nicosulfuron, and 97.51% of the plants survived. In contrast, the NS plants wilted or completely died, resulting in the total loss of plants as the time of exposure was prolonged [22]. Thus, the concentration of 80 mg kg -1 was chosen for the rest of experiment.…”

“…and induce osmotic stress and ROS [10,37]. The subsequent increase in antioxidative capacity protected the nicosulfuron-resistant maize from the severe damage caused by nicosulfuron stress [22]. Osmotic stress and the accumulation of ROS could also be associated with the accumulation of soluble sugar, which has generally been considered to be an adaptive response to the nicosulfuron stress [38].…”

“…Spraying nicosulfuron affects the photosynthetic mechanism by altering the metabolism of plant cells, which results in the disintegration of chloroplasts and a change in the leaf color of plants. The photosynthetic pigments and photosynthetic-related protein activities of plants are significantly reduced, and nicosulfuron destroys the chloroplast structure [20][21][22]. Thus, the photosynthetic ability to assimilate carbon, absorb light and transmit it, and distribute this energy between photosystem II (PSII) and PSI decrease, which results in the inability to synthesize ATP and NADPH [23].…”

“…The activity of C 4 photosynthetic enzymes and expression of key genes are extremely significant in enabling sweet maize plants to withstand nicosulfuron stress at a photosynthetic physiological level with different degrees of resistance to this herbicide [19]. After treatment with nicosulfuron, the nicosulfuron-tolerant maize had significantly higher net photosynthetic rates, transpiration rates, stomatal conductance, leaf maximum photochemical efficiency of PSII, photochemical quenching of chlorophyll fluorescence, and electron transport rates compared with those for nicosulfuron-sensitive maize [22]. The results from our preliminary studies indicate that plants can improve photosynthesis to alleviate the phytotoxic effects of nicosulfuron.…”

The sulfonylurea herbicide nicosulfuron is efficient, harmless and selective at low doses and has been widely used in maize cultivation. In this study, a pair of corn sister lines, HK301 (nicosulfuron-tolerence, NT) and HK320 (nicosulfuron-sensitive, NS), was chosen to study the effect of nicosulfuron on plant growth and sugar metabolism in sweet maize (Zea mays L.) seedlings. All the experimental samples were subjected to treatment with water or 80 mg kg–1 of nicosulfuron when the sweet maize seedlings grew to the four-leaf stage. Nicosulfuron significantly inhibited the growth of NS line. The content of sucrose and the activities of sucrose phosphate synthase and sucrose synthase in the two inbred lines increased differentially under nicosulfuron stress compared with the respective control treatment. After nicosulfuron treatment, the activities of hexokinase and 6-phosphofructokinase and the contents of pyruvic acid and citric acid in NS line decreased significantly compared with those of NT line, while the content of sucrose and activities of sucrose phosphate synthase and sucrose synthase increased significantly. The disruption of sugar metabolism in NS line led to a lower supply of energy for growth. This study showed that the glycolysis pathway and the tricarboxylic acid cycle were enhanced in nicosulfuron-tolerant line under nicosulfuron stress in enhancing the adaptability of sweet maize.

In order to reduce the harmful effects of nisulfuron on sweet corn, the physiological regulation mechanism of sweet corn detoxi cation was studied. In this study, a pair of sister lines of sweet corn(nicosulfurontolerant"HK310" and nicosulfuron-sensitive "HK320")were used to analyze the effects of nicosulfuron stress on glyoxalase system, hormone content and key gene expression on sweet corn seedlings. The results showed that after spraying nicosulfuron, methyl glyoxal (MG) content in HK301 increased rst and then decreased. As well as, the activities of glyoxalaseI (GlyI) and glyoxalaseII (GlyII), the content of non-enzymatic glutathione (GSH) and the glutathione redox state glutathione/ (glutathione + glutathione disul de) (GSH/ (GSH + GSSG)) showed the same trend as the MG content. Besides, the contents of ababic acid (ABA), gibberelin (GA) and zeatin nucleoside (ZR) also increased rst and then decreased, and auxin (IAA) content increased continuously. In HK301, all indexes after spraying nicosulfuron were signi cantly greater than those of control. In HK320, MG accumulation continued to increase after nicosulfuron spraying, and the activities of GlyI and GlyII and GSH content rst increased and then decreased after 1d stress. The indicators above are signi cantly greater than the control. While the ratio of GSH/ (GSH + GSSG) showed a decreasing trend and signi cantly smaller than the control. Furthermore, the contents of ABA and IAA continued to increase, and the contents of GA and ZR rst increased and then decreased. Compared with HK320, HK301 signi cantly upregulated the transcription levels of GlyI and GlyII genes in roots, stems and leaves. Comprehensive analysis showed that sweet maize seedlings with different drug resistance improved their herbicide resistance by changing glyoxalase system and regulating endogenous hormones. The results provided a theoretical basis for further understanding the response mechanism of glyoxalase system and the regulation characteristics of endogenous hormones in maize under the stress of nianysulfuron.
