“…The positive role of AMF for improving alkali tolerance in P. tenuiflora was reflected in the increased growth and K + /Na + ratio after AMF inoculation under AS. These results are consistent with previous studies on Leymus chinensis (Lin et al, 2017), Avena sativa (Xun, Xie, Liu, & Guo, 2015), Zea mays (Zhang, Cao, Zhang, & Wang, 2016), and Vicia faba (Abd-Alla, El-Enany, Nafady, Khalaf, & Morsy, 2014). AMF inoculation is known to mediate phosphorus uptake in host plants, which can improve plant growth in a salt-alkali environment (Alkaraki, 2000;Hirrel & Gerdemann, 1980).…”

“…Salt‐alkaline soil is one of the major abiotic constraints that limit plant distribution and yield, and this soil will cover >50% of arable lands throughout the world by 2050 (Yu, Chen, Wang, Sun, & Dai, ; Zhang et al, ). In the northeast of China, alkaline meadows cover >70% of the land, and the area continues to expand (Lin, Wang, Sun, Mu, & Yan, ). Alkaline stress (NaHCO 3 or Na 2 CO 3 ) is more severe than saline stress due to its unique high pH, which can inhibit ion uptake and disrupt the ionic balance of plant cells (Lin et al, ; Yang, Zheng, Tian, Wu, & Zhou, ).…”

Alkali soil is a major abiotic constraint that limits plant distribution and yield in the northeast of China. Puccinellia tenuiflora is considered the most promising grass species for salt‐alkali grassland restoration. However, there is little information on the molecular mechanisms underlying how arbuscular mycorrhizal fungi (AMF) enhances P. tenuiflora stress responses in alkali‐degraded soil. In this study, AMF colonization, growth, photosynthetic pigments, and inorganic ion contents were measured. Isobaric tags for relative and absolute quantification‐based quantitative proteomic technology were employed to identify the differentially abundant proteins in P. tenuiflora seedlings with or without AMF under alkalinity stress. The results showed that AMF colonization increased seedling biomass, photosynthetic pigment contents, and K+/Na+ ratio under alkalinity stress. Moreover, a total of 598 proteins were significantly differentially regulated in P. tenuiflora seedlings after AMF inoculation under alkalinity stress compared with under alkalinity stress alone. The results showed that AMF inoculation significantly improved protein synthesis, reactive oxygen species scavenging, and nitrogen metabolism to promote the biosynthesis of osmotic substances in response to alkalinity stress. In addition, P. tenuiflora seedlings produced more energy to compensate for the energy loss caused by alkalinity stress after AMF inoculation. In conclusion, these findings provide new insights into the physiological mechanisms of the response to alkali‐degraded soil in P. tenuiflora seedlings with AMF and also clarify the role of AMF in the molecular regulation network of P. tenuiflora under alkalinity stress.

“…For short-term mixed alkali stress, the gene expression gradually increased as time increased in the two ecotypes; this result differs from that observed with mixed salt stress. In general, the damage from alkaline salt was severer than neutral salt stress to the plant [28]. Alkali stress could lead to high pH in the plant growth environment and interfere with control of Na þ uptake in roots.…”

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a housekeeping protein which plays various roles in non-metabolic processes in addition to its role in glucose catabolism. There are several GAPDH isoforms in plant cells. In this study, we cloned the full-length cDNA encoding the isoform GAPC in two ecotypes of Leymus chinensis (Trin.) Tzvelev, gray-green type and yellow-green type. The LcGAPC sequence includes an open reading frame (ORF) of 1014 bp encoding 337 amino acids. The predicted molecular weight is 36.5 kDa, and the pI is 6.19. The mRNA expression of LcGAPC decreased at 24 h and then increased significantly after 7 d after 400 mmol/L NaCl stress. At 200 mmol/L mixed alkali stress (NaHCO 3 :Na 2 CO 3 ¼9:1), the LcGAPC expression level gradually increased as time increased in the two ecotypes of L. chinensis. The results suggested that LcGAPC is a stress-inducible gene that might play a role in the salt and alkali stress response. This study provided a basis to further study the mechanism of expression characteristics under salt and alkali stress conditions of L. chinensis. ARTICLE HISTORY

“…It was verified that AMF was able to increase the resistance to salinity by accumulating various osmotic adjustment substances (Lin et al, 2017;Porcel et al, 2012), improving antioxidant enzyme activities (Huang et al, 2010), and facilitating the absorption and transfer of nutrients (Liu et al, 2013). Research of influential mechanism of salinity on photosynthesis was still at its preliminary stage, and the exploration of many key issues need to be urgently deepened.…”

The impact of arbuscular mycorrhizal fungi (AMF) Glomus. tortuosum on morphology, photosynthetic pigments, chlorophyll (Chl) fluorescence, photosynthetic capacity and rubisco activity of maize under saline stress were detected under potted culture experiments. The experimental result indicated the saline stress notably reduced both dry mass and leaf area in contrast with the control treatment. Nevertheless, AMF remarkably ameliorated dry mass and leaf area under saline stress environment. Besides, maize plants appeared to have high dependency on AMF which improved physiological mechanisms by raising chlorophyll content, efficiency of light energy utilization, gas exchange and rubisco activity under salinity stress. In conclusion, AM could mitigate the growth limitations caused by salinity stress, and hence play a very important role in promoting photosynthetic capacity under salt stress in maize.
