Superoxide dismutase gene family in cassava revealed their involvement in environmental stress via genome-wide analysis
نویسندگان
چکیده
Superoxide dismutase (SOD) is a crucial metal-containing enzyme that plays vital role in catalyzing the dismutation of superoxide anions, converting them into molecular oxygen and hydrogen peroxide, essential for enhancing plant stress tolerance. We identified 8 SOD genes (4 CSODs, 2 FSODs, MSODs) cassava. Bioinformatics analyses provided insights chromosomal location, phylogenetic relationships, gene structure, conserved motifs, ontology annotations. MeSOD were classified two groups through analysis, revealing evolutionary connections. Promoters these harbored stress-related cis-elements. Duplication analysis indicated functional significance MeCSOD2/MeCSOD4 MeMSOD1/MeMSOD2. Through qRT-PCR, MeCSOD2 responded to salt stress, MeMSOD2 drought, cassava bacterial blight. Silencing increased XpmCHN11 virulence, indicating cassava’s defense against infection. These findings enhance our understanding family’s contribute strategies tolerance improvement.

Genome-Wide Analysis of the GRF Family Reveals Their Involvement in Abiotic Stress Response in Cassava
GENERAL REGULATORY FACTOR (GRF) proteins play vital roles in the regulation of plant growth, development, and response to abiotic stress. However, little information is known for this gene family in cassava (Manihot esculenta). In this study, 15 MeGRFs were identified from the cassava genome and were clustered into the ε and the non-ε groups according to phylogenetic, conserved motif, and gene ...

Superoxide dismutase (SOD) as a group of significant and ubiquitous enzymes plays a critical function in plant growth and development. Previously this gene family has been investigated in Arabidopsis and rice; it has not yet been characterized in cotton. In our study, it was the first time for us to perform a genome-wide analysis of SOD gene family in cotton. Our results showed that 10 genes of...
متن کاملBioinformatics Genome-Wide Characterization of the WRKY Gene Family in Sorghum bicolor
The WRKY gene family encodes a large group of transcription factors that regulate genes involved in plant response to biotic and abiotic stresses. Sorghum is a notable grain and forage crop in semi-arid regions because of its unusual tolerance against hot and dry environments. We identified a set of 85 WRKY genes in the S. bicolor genome and classified them into three groups (I–III). Among the ...

Mitogen-activated protein kinases (MAPKs) play central roles in plant developmental processes, hormone signaling transduction, and responses to abiotic stress. However, no data are currently available about the MAPK family in cassava, an important tropical crop. Herein, 21 MeMAPK genes were identified from cassava. Phylogenetic analysis indicated that MeMAPKs could be classified into four subfa...
