摘要： Background: Posttranslational modification of proteins by small ubiquitin like modifier (SUMO) proteins play an important role during the developmental process and in response to abiotic stresses in plants. However, little is known about SUMOylation in peanut (Arachis hypogaea L.), one of the world's major food legume crops. In this study, we characterized the SUMOylation system from the diploid progenitor genomes of peanut, Arachis duranensis (AA) and Arachis ipaensis (BB). Results: Genome-wide analysis revealed the presence of 40 SUMO system genes in A. duranensis and A. ipaensis. Our results showed that peanut also encodes a novel class II isotype of the SCE1, which was previously reported to be uniquely present in cereals. RNA-seq data showed that the core components of the SUMOylation cascade SUMO1/2 and SCE1 genes exhibited pod-specific expression patterns, implying coordinated regulation during pod development. Furthermore, both transcripts and conjugate profiles revealed that SUMOylation has significant roles during the pod development. Moreover, dynamic changes in the SUMO conjugates were observed in response to abiotic stresses. Conclusions: The identification and organization of peanut SUMO system revealed SUMOylation has important roles during stress defense and pod development. The present study will serve as a resource for providing new strategies to enhance agronomic yield and reveal the mechanism of peanut pod development.
