“…Genes, such as MaCSD2A , MaMSD1A , MaMSD1B , MaMSD1C and MaFSD1A , transcribe two to four different mRNAs as a result of APA. This is not surprising because APA transcripts have already been detected in Cu/ZnSOD , MnSOD and FeSOD genes from Dimocarpus longan , L. gmelinii , T. aestivum and Z. mays [ 10 , 12 , 43 ] . Like APA, AS is a regulatory mechanism to generate multiple transcripts from one single gene.…”

“…This indicated that the regulation of SOD genes is complicated in response to oxidative stress. Cis -element and transcription factor analyses of SOD promoters from Arabidopsis [ 6 ], wheat [ 12 ] and longan [ 10 ] provided some clues on how the SOD genes are modulated. Additionally, alternative splicing (AS) and miRNAs have also found to be involved in the regulation of SOD expression [ 18 , 19 ].…”

BackgroundSuperoxide dismutase (SOD) is an essential enzyme of the plant antioxidant system that responds to oxidative stresses caused by adverse conditions. Banana is an important staple and economic crop in tropical and subtropical regions. However, its growth and yield are constantly affected by various abiotic stresses. To analyze the roles of distinct SOD genes under various stresses, a detailed characterization and analysis of the SOD gene family in Cavendish banana is indispensable.MethodsThe presence and structure of the SOD family genes were experimentally verified using 5′/3′ RACE-PCR, reverse transcription PCR and PCR. Then, their syntenic relationships, conserved motifs and phylogenetic relationships were analyzed using software. Cis-elements present in the promoters were predicted via PlantCARE. And the expression levels under abiotic and hormonal stresses were determined using real-time quantitative polymerase chain reaction.ResultsIn total, 25 ‘Tianbaojiao’ SOD cDNAs (MaSODs), which encoded six Cu/ZnSODs, four MnSODs and two FeSODs, were cloned. The 12 MaSOD genes were divided into four groups based on their conserved motifs, which corroborated their classifications based on gene-structure patterns and subcellular localizations. Eleven MaSOD promoters were isolated and found to contain many cis-acting elements involved in stress responses. Gene expression analysis showed that 11 out of the 12 MaSODs were expressed in all tested tissues (leaf, pseudostem and root), whereas MaCSD2B was expressed only in leaves and roots. Specific MaSOD members exhibited different expression patterns under abiotic and hormonal treatments. Among the 12 MaSOD genes, MaCSD1D was the only one that responded to all eight treatments, suggesting that this gene plays a predominant role in reactive oxygen species scavenging caused by various stresses in banana.ConclusionsA genome-wide analysis showed that the ‘Tianbaojiao’ banana harbored an expanded SOD gene family. Whole genome duplication, segmental duplication and complex transcriptional regulation contributed to the gene expansion and mRNA diversity of the MaSODs. The expression patterns of distinct MaSOD genes showed that they are important responses to different abiotic and hormonal stresses in banana.Electronic supplementary materialThe online version of this article (doi:10.1186/s12864-015-2046-7) contains supplementary material, which is available to authorized users.

“…SOD plays important roles in multiple processes of plant growth and resistance against environment stresses, and SOD gene family has been reported to be widely distributed in different plant species, such as Arabidopsis [ 40 ], longan [ 41 ], rice [ 34 , 42 ], poplar [ 22 ], banana [ 10 ], sorghum [ 35 ], tomato [ 6 ], and cotton [ 36 , 43 ]. However, no comprehensive analysis of this gene family has been reported in cucumber.…”

Superoxide dismutase (SOD) proteins are widely present in the plant kingdom and play important roles in different biological processes. However, little is known about the SOD genes in cucumber. In this study, night SOD genes were identified from cucumber (Cucumis sativus) using bioinformatics-based methods, including 5 Cu/ZnSODs, 3 FeSODs, and 1 MnSOD. Gene structure and motif analysis indicated that most of the SOD genes have relatively conserved exon/intron arrangement and motif composition. Phylogenetic analyses with SODs from cucumber and several other species revealed that these SOD proteins can be traced back to two ancestral SODs before the divergence of monocot and dicot plants. Many cis-elements related to stress responses and plant hormones were found in the promoter sequence of each CsSOD gene. Gene expression analysis revealed that most of the CsSOD genes are expressed in almost all the tested tissues. qRT-PCR analysis of 8 selected CsSOD genes showed that these genes could respond to heat, cold, osmotic, and salt stresses. Our results provide a basis for further functional research on SOD gene family in cucumber and facilitate their potential applications in the genetic improvement of cucumber.

“…In a very recent study, six Cu/Zn-SODs and two Fe-SODs were identified in grapevine and the expression analysis established a clear correlation of these genes in light stress resistance as well as in different aspects for abiotic stress management [33]. Other recent studies demonstrated a key role of SODs towards different environmental stresses in plants, such as ethylene, salinity, drought and low temperature [34,35] in various monocots and dicots species including Arabidopsis thaliana [36], Dimocarpus longan [34], Sorghum bicolor [37], Populus trichocarpa [38], Musa acuminate [33], Gossypium raimondii and Gossypium arboreum [39].…”

Despite the numerous beneficial properties and uses of chitosan in agriculture, the molecular mechanisms behind its elicitation potential are still unclear. This study aimed at understanding the effect of chitosan application in the levels of phenolic compounds of Vitis vinifera L. red grapes berry skin (cv. Tinto Cão) during veraison. Grapevines were treated with chitosan (0.01% in 0.01% acetic acid) while control grapevines were sprayed with 0.01% acetic acid. Results showed that several monomeric anthocyanins increased significantly in berry skins after treatment with chitosan. Additionally, Catechin, Rutin and Querecetin-3-O-galactoside were also recorded in higher amount upon chitosan treatment. Besides modulating the phenolic content, chitosan treatment also induced modifications in several target genes encoding key enzymes and transporters involved in secondary metabolic pathways. For instance, the genes PAL, CHS, F3H, ANR, UFGT, ABCC1, GST, MATE1 were upregulated in leaves and berry skins at veraison cessation in response to chitosan treatment. Overall, the results demonstrated that chitosan has a stimulatory effect on the accumulation of phenolic compounds, including anthocyanins, mediated by modifications in the transcription of key genes involved in their biosynthesis and transport in grape berries.
