“…AtSRO1 and AtRCD1, two homologous genes, have functional redundancy under different stress conditions [9]. AtSRO1 is involved in abiotic stress response, and its mutant SRO1-1 has strong resistance to osmotic and oxidative stress [3,10]. AtSRO5 interacts with transcription factors to regulate gene expression, and overexpression of AtSRO5 can increase the salt tolerance of transgenic plants by lowering the level of H 2 O 2 in the roots [11].…”

Similar to radical-induced cell death 1 (SROs) is a family of small proteins unique to plants. SRO transcription factors play an important role in plants’ response to biotic and abiotic stresses. In this study, we identified 12 BrSRO genes in Chinese cabbage (Brassica rapa L.). Among them, a comprehensive overview of the SRO gene family is presented, including physical and chemical characteristics, chromosome locations, phylogenetic analysis, gene structures, motif analysis, and cis-element analyses. The number of amino acids of BrSRO genes is between 77–779 aa, isoelectric point changed from 6.02 to 9.6. Of the 12 BrSRO genes, 11 were randomly distributed along the 7 chromosomes, while BrSRO12 was located along unassigned scaffolds. Phylogenetic analysis indicated that the SRO proteins from six species, including Arabidopsis, banana, rice, Solanum lycopersicum, Zea mays, and Chinese cabbage were divided into eleven groups. The exon-rich BrSRO6 and BrSRO12 containing 15 exons were clustered to group K. All 12 genes have motif 2, which indicate that motif 2 is a relatively conservative motif. There are many hormone and stress response elements in BrSRO genes. The relative expression levels of 12 BrSRO genes under high temperature, drought, salt, and low temperature conditions were analyzed by real-time fluorescence quantitative PCR. The results indicated the relative expression level of BrSRO8 was significantly up-regulated when plants were exposed to high temperature. The relative expression levels of BrSRO1, 3, 7, 8, and 9 were higher under low temperature treatment. The up-regulated genes response to drought and salt stresses were BrSRO1, 5, 9 and BrSRO1, 8, respectively. These results indicated that these genes have certain responses to different abiotic stresses. This work has provided a foundation for further functional analyses of SRO genes in Chinese cabbage.

“…Arabidopsis genes with collinearity with StGPXL have been reported many times; for example, AtGPXL controls the root structure by mediating redox regulation [ 32 ]; the expression levels of AtGPXL2 and AtGPXL7 increase under ultraviolet (UV-B) stress to eliminate the lethal damage of ultraviolet radiation to plants [ 33 ]; AtGPXL3 not only acts as a scavenger under ABA and drought stress but also as a signaling molecule to specifically transmit H 2 O 2 signals [ 15 ]. At the same time, it can physically interact with SRO1 to regulate the oxidative homeostasis in ROS cells under heavy metal mercury stress to avoid plant damage [ 34 ]; AtGPXL1 and AtGPXL7 affect leaf development and tolerance to photooxidative stress in Arabidopsis [ 16 ]. Therefore, it can be inferred that the StGPXL gene will have similar biological functions.…”

Glutathione peroxidase-like enzyme is an important enzymatic antioxidant in plants. It is involved in scavenging reactive oxygen species, which can effectively prevent oxidative damage and improve resistance. GPXL has been studied in many plants but has not been reported in potatoes, the world’s fourth-largest food crop. This study identified eight StGPXL genes in potatoes for the first time through genome-wide bioinformatics analysis and further studied the expression patterns of these genes using qRT-PCR. The results showed that the expression of StGPXL1 was significantly upregulated under high-temperature stress, indicating its involvement in potato defense against high-temperature stress, while the expression levels of StGPXL4 and StGPXL5 were significantly downregulated. The expression of StGPXL1, StGPXL2, StGPXL3, and StGPXL6 was significantly upregulated under drought stress, indicating their involvement in potato defense against drought stress. After MeJA hormone treatment, the expression level of StGPXL6 was significantly upregulated, indicating its involvement in the chemical defense mechanism of potatoes. The expression of all StGPXL genes is inhibited under biotic stress, which indicates that GPXL is a multifunctional gene family, which may endow plants with resistance to various stresses. This study will help deepen the understanding of the function of the potato GPXL gene family, provide comprehensive information for the further analysis of the molecular function of the potato GPXL gene family as well as a theoretical basis for potato molecular breeding.

“…Although, AtSRO1 and AtRCD1 have functional redundancy related to plant development but functional variations exist in response to abiotic stresses (18). For example, mutations of AtSRO1 could improve plant tolerance under osmotic and oxidative stresses (10) but mutations of AtRCD1 compromised plant tolerance to salt stress (23).…”

Background SRO (Similar to RCD1) genes family is largely recognized for their importance in growth, development and in responding to environmental stresses. However, genome-wide identification and functional characterization of SRO genes from cotton species have not reported so far. Results A total of 36 SRO genes were identified from four cotton species. Phylogenetic analysis divided these genes into three groups with distinct structure. Syntenic and chromosomal distribution analysis indicated uneven distribution of GaSRO, GrSRO, GhSRO and GbSRO genes on A2, D5 genomes, Gh-At, Gh-Dt and Gb-At, Gb-Dt subgenomes, respectively. Gene duplication analysis revealed the presence of six duplicated gene pairs among GhSRO genes. In promoter analysis, several elements responsive to growth, development and hormones were interpreted in GhSRO genes, implying the reason for their induction during growth and developmental stages. Several miRNAs responsive to plant growth and abiotic stress responses were predicted that target 12 GhSRO genes. Organ-specific expression profiling explored the roles of GhSRO genes in one or more tissues. In addition, specific expression pattern of some GhSRO genes during ovule developmental stages depicted their involvement in these developmental processes. Conclusion The data presented in this report laid a foundation for understanding the classification and functions of SRO genes in cotton.
