Phytoremediation is an attractive environmental-friendly technology to remove metal(loid)s from contaminated soils and water. However, tolerance to toxic metals in plants is a critical limiting factor. Transgenic Crambe abyssinica lines were developed that overexpress the bacterial γ-glutamylcysteine synthetase (γ-ECS) gene to increase the levels of non-protein thiol peptides such as γ-glutamylcysteine (γ-EC), glutathione (GSH), and phytochelatins (PCs) that mediate metal(loid)s detoxification. The present study investigated the effect of γ-ECS overexpression on the tolerance to and accumulation of toxic As, Cd, Pb, Hg, and Cr supplied individually or as a mixture of metals. Compared to wild-type plants, γ-ECS transgenics (γ-ECS1-8 and γ-ECS16-5) exhibited a significantly higher capacity to tolerate and accumulate these elements in aboveground tissues, i.e., 76-154% As, 200-254% Cd, 37-48% Hg, 26-69% Pb, and 39-46% Cr, when supplied individually.

The levels of Cys and γ-EC were also increased by 56-67% and 450-794% in the overexpression lines compared to WT plants under non-stress conditions, respectively. This likely enhanced the metabolic pathway associated with GSH biosynthesis, leading to the ultimate synthesis of PCs, which detoxify toxic metal(loid)s through chelation.

Aux/IAA genes are key genes involved in regulating auxin signal transduction in plants. Although IAA genes have been characterized in various plant species, the role of IAA genes in grape cold resistance is unclear. To further explore the members of the Aux/IAA gene family in grape and their functions, in this study, using genomic data for Pinot Noir (Vitis vinifera cv. 'Pinot Noir') and Shanputao (Vitis amurensis), 25 VvIAA genes and 18 VaIAA genes were identified. The VaIAA genes presented different expression patterns at five different temperatures (28 ± 1 °C, 5 ± 1 °C, 0 ± 1 °C, -5 ± 1 °C, and -10 ± 1 °C) according to qRT‑PCR results. VaIAA3 was selected as a candidate gene for further functional analysis because of its high expression level under low-temperature stress. Subcellular localization experiments revealed that VaIAA3 was localized in the nucleus. Additionally, under 4 °C treatment for 24 h, relative expression level of VaIAA3, antioxidant enzyme activity, survival rate, and cold-responsive gene expression in three transgenic lines (OE-1, OE-2, OE-3) were greater, whereas relative electrolytic conductivity (REC), malondialdehyde (MDA) content and hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) content were lower than those of the wild type (WT). Transcriptome sequencing analysis revealed that VaIAA3 regulated cold stress resistance in Arabidopsis thaliana (Arabidopsis) through pathways involving auxin, ABA, JA, or ethylene. Importantly, heterologous overexpression of VaIAA3 increased the resistance of Arabidopsis to cold stress, which provides a theoretical basis for the further use of VaIAA3 to improve cold resistance in grape.</p>","PeriodicalId":20204,"journal":{"name":"Plant Cell Reports","volume":null,"pages":null},"PeriodicalIF":5.3,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142472869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
