“…In this work, we identify a chloroplast localized 2-Cys Prx encoding gene TaBAS1 ( Figure 1 ), and its overexpression obviously enhances salt tolerance in wheat and Arabidopsis ( Figures 3 , S3 ) ( Xu et al., 2016 ). In line with the reports that the enhancement of salt tolerance by 2-Cys Prxs from Suaeda salsa L. and Tamarix hispida ( Jing et al., 2006 ; Wang et al., 2020 ), our data indicate that the role of 2-Cys-Prxs in salt tolerance is conserved in different plants. Moreover, TaBAS1 enhances grain yield of wheat under salt stress, but has no adverse effect on the growth and yield under the control condition ( Figure 7 ), exhibiting its potential in the germplasm improvement of wheat without imposing the trade-offs between yield and tolerance.…”

“…Note that TaBAS1 overexpression enhances the tolerance to H 2 O 2 in wheat but not Arabidopsis ( Figure S4 ), which may owe to the difference in the response threshold to H 2 O 2 treatment that need to be studied in the future. Moreover, TaBAS1 promotes the activities of ROS scavenging enzymes SOD, GPX and CAT ( Figures 5A–C ), consistent with the previous studies that 2-Cys Prxs elevate these ROS scavenging enzymes in other plants ( Pulido et al., 2010 ; Wang et al., 2020 ; Xu et al., 2022 ). This indicates that 2-Cys Prxs can affect the ROS scavenging system to efficiently remove excessive ROS together.…”

Efficient antioxidant enzymatic system contributes to salt tolerance of plants via avoiding ROS over-accumulation. Peroxiredoxins are crucial components of the reactive oxygen species (ROS) scavenging machinery in plant cells, but whether they offer salt tolerance with potential for germplasm improvement has not been well addressed in wheat. In this work, we confirmed the role of a wheat 2-Cys peroxiredoxin gene TaBAS1 that was identified through the proteomic analysis. TaBAS1 overexpression enhanced the salt tolerance of wheat at both germination and seedling stages. TaBAS1 overexpression enhanced the tolerance to oxidative stress, promoted the activities of ROS scavenging enzymes, and reduced ROS accumulation under salt stress. TaBAS1 overexpression promoted the activity of ROS production associated NADPH oxidase, and the inhibition of NADPH oxidase activity abolished the role of TaBAS1 in salt and oxidative tolerance. Moreover, the inhibition of NADPH-thioredoxin reductase C activity erased the performance of TaBAS1 in the tolerance to salt and oxidative stress. The ectopic expression of TaBAS1 in Arabidopsis exhibited the same performance, showing the conserved role of 2-Cys peroxiredoxins in salt tolerance in plants. TaBAS1 overexpression enhanced the grain yield of wheat under salt stress but not the control condition, not imposing the trade-offs between yield and tolerance. Thus, TaBAS1 could be used for molecular breeding of wheat with superior salt tolerance.

“…ThSAP30BP may play an important physiological role in the salt tolerance of T. hispida [ 23 ]. The 2-Cys peroxidase gene of this plant improves its tolerance to salt stress [ 24 ]. ThNAC7 induces the transcriptional levels of genes associated with stress tolerance to enhance salt and osmotic tolerance by increasing osmotic potential and enhanced ROS scavenging capability [ 25 ].…”

Background Seed germination is a series of ordered physiological and morphogenetic processes and a critical stage in plant life cycle. Tamarix hispida is one of the most salt-tolerant plant species; however, its seed germination has not been analysed using combined transcriptomics and metabolomics. Results Transcriptomic sequencing and widely targeted metabolomics were used to detect the transcriptional metabolic profiles of T. hispida at different stages of seed germination and young seedling growth. Transcriptomics showed that 46,538 genes were significantly altered throughout the studied development period. Enrichment study revealed that plant hormones, such as auxin, ABA, JA and SA played differential roles at varying stages of seed germination and post-germination. Metabolomics detected 1022 metabolites, with flavonoids accounting for the highest proportion of differential metabolites. Combined analysis indicated that flavonoid biosynthesis in young seedling growth, such as rhoifolin and quercetin, may improve the plant’s adaptative ability to extreme desert environments. Conclusions The differential regulation of plant hormones and the accumulation of flavonoids may be important for the seed germination survival of T. hispida in response to salt or arid deserts. This study enhanced the understanding of the overall mechanism in seed germination and post-germination. The results provide guidance for the ecological value and young seedling growth of T. hispida.

“…In this study, the proteins whose expression levels were elevated upon exposure to high temperatures, were associated with the process of stress tolerance. Cationic peroxidase 1 (Li et al 2020), phosphoserine phosphatase (Ho and Saito 2001), and peroxiredoxins (Wang et al 2020), were associated with responses to biotic and abiotic stresses that entailed the decomposition of reactive oxygen species and prevention of changes to cell membrane permeability. Expression levels of E3 ligase (Stone 2019), Hul5 HECT ubiquitin ligase (Fang et al 2011), and F-box protein (Li et al 2018) showed an increase in some temperatures, and a decrease in other temperatures.…”

Temperature conditions affect growth and grain development during the grain-filling stage, but a comprehensive analysis of oat subjected to different temperatures during grain development has not been studied. In this study, an integrated physiological and proteomic examination of oat spikelets was performed to analyze the influence of five different day-time temperatures on stress-relative parameters and grain development. Physiological analysis showed decrease of total chlorophyll, shoot dry weight and spikelet shape development and increased activation of MDA, soluble sugar and antioxidant enzymes, with increase of temperatures. However, considering major grain yield components and storage materials, there should be an optimum temperature during ripening period. The result of proteomic analysis showed significantly high expressions of stress-related gene in high temperature treatment and grain storage materials in optimum temperature. Our findings indicate that temperature conditions during the grain-filling period exert a major influence on yield potential.
