However, the mechanisms of Al detoxification by Si needs to be further clarified, especially in soybean. We investigated the roles of citrate secretion and cell wall polysaccharides in Si-triggered soybean resistance to Al stress. Results showed that applying 2 mM Si alleviated elongation inhibition of soybean roots exposed to 100 or 200 µM Al for 24 h. Si application increased citrate exudation from roots under Al exposure, thereby reducing Al accumulation. Furthermore, Si promoted citrate synthesis through activating citrate synthase and inhibiting aconitase under Al stress. Quantitative real-time PCR assay showed that Si enhanced the expression level of citrate transporter genes (<i>GmMATE13</i> and <i>GmMATE47</i>) under Al stress. In addition, Si supply reduced Al content in cell wall and in cell wall polysaccharides (pectin and hemicellulose 1) under Al exposure. Meanwhile, Si addition decreased the contents of pectin and hemicellulose 1, which were the main binding sites for Al in cell wall, under Al exposure. Furthermore, Si increased the degree of pectin methylesterification by inhibiting pectin methylesterase activity under Al stress, thereby reducing the ability of pectin to bind Al. These results suggest that Si can promote citrate efflux by regulating the synthesis and transport of citrate, thus chelating the toxic Al cations and alleviating Al toxicity. Besides, Si can also regulate the cell wall properties to reduce Al deposition in the cell wall of root tip, thereby improving Al tolerance of soybean.</p></div>","PeriodicalId":6973,"journal":{"name":"Acta Physiologiae Plantarum","volume":"47 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142761985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this experiment was to evaluate the impact of arbuscular mycorrhizal fungi on the photosynthetic physiology of strawberries under salinity stress. The greenhouse experiment involved the strawberry cultivar ‘Benihoppe’, which was inoculated with <i>Glomus mosseae</i> under three salt stress levels (0 mM, 30 mM, and 60 mM).

Under salt stress, especially at the concentration of 60 mM. Pn, Gs, Tr, Ci, Fv/Fm, and NPQ showed significant differences. After inoculation of AMF, arbuscular mycorrhiza established a beneficial symbiotic relationship with strawberry roots, which effectively reduced salt damage and promoted the growth of strawberry plants. Leaf area, fresh biomass, and relative chlorophyll content were significantly increased. Pn, Tr, and Gs of mycorrhizal strawberry were significantly higher than those of control group. In addition, the light energy conversion efficiency of strawberry plants inoculated with AMF was improved, thus increasing the potential photosynthetic capacity and photosynthetic rate of strawberry.</p></div>","PeriodicalId":6973,"journal":{"name":"Acta Physiologiae Plantarum","volume":"46 12","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142714409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
