SUMOylation of rice DELLA SLR1 modulates transcriptional responses and improves yield under salt stress.

ABSTRACT: This work aimed to characterize the molecular differences of SUMO1-SLR1 and SLR1 in rice (Oryza sativa cv. Nipponbare) shoots subjected to salt stress and to identify novel SLR1 interactors. Because DELLA proteins regulate gene expression, we exposed SLR1-OX, SUMO1SLR1-OX, and Nipponbare genetic background to high salt concentrations (120 mM NaCl) during 8 hours at the seedling stage and collected samples for subsequent RNA-seq analysis. Functional annotation of SLR1-OX DEGs showed enrichment of gene ontology (GO) terms associated with diterpenoid biosynthesis, highlighting the impact of SLR1 on GA metabolism. After functional annotation of DEGs specific to SUMO1SLR1-OX, we found a significant over-representation of GO terms associated with defense response and gibberellin dioxygenase ac
