Abstract

SAP and MIZ (SIZ) is a small ubiquitin-related modifier (SUMO) E3 ligase that facilitates conjugation of SUMO to protein substrates. Although there have been a number of reports about the functions of SIZ1 in Arabidopsis in the regulation of diverse life processes, no information regarding the role of SIZ in other plants is available yet. In this work, two homologous genes from rice (Oryza sativa) were isolated and designated as OsSIZ1 and OsSIZ2 based on amino acid sequence homology to AtSIZ1 and their phylogenetic relationship. The function in the vegetative growth and reproductive development in rice was investigated using OsSIZ1 mutants containing a T-DNA insertion. The results showed that the mutant Ossiz1 exhibited the significant changes in several growth and developmental parameters, including primary root length, adventitious root number, plant height, leaf and panicle length, flower formation, and seed-setting rate compared with wild type. Taking together these results indicate that OsSIZ1 plays an important role in regulating growth and development in rice.
