 ===Function===
-The Shortened Uppermost Internode 1(SUI1) family of genes are pivotal for development of rice stems. SUI-family genes regulate the development of intercalary meristem(IM) for internode elongation and also the cell expansion of the panicle stem rachis in rice. The SUI-family genes encode base-exchange types of phosphatidylserine synthases (PSSs), which possess enzymatic activity in a yeast complementary assay.

      SUI-family genes encode BE-PSSs, which are crucial for PS maintenance in plants. SUI1 possess the enzymatic activity and can catalyze PC or PE into PS in yeast. Measurement of PS levels revealed that the total PS contents of neither the sui2 mutant nor the SUI1 ectopic expression plant was signiﬁcantly reduced. The VLCFA-PS levels are signiﬁcantly altered in both sui2 mutants and SUI1 over-expressed plants, implying that SUI-family genes might be directly involved in VLCFA-PS biosynthesis. It is possible that the distribution of VLCFA-PS in the membrane provides signal information for downstream function in SUI-family genes. Confocal analysis of SUI1:GFP reveals SUI1 protein localized in the plasma membrane. In Arabidopsis, the AtPSS1 protein was found mainly in nuclei and the ER membrane in pollen cells. Protein puriﬁcation analysis in mammal cells indicates that PSS1 and PSS2 proteins are mainly localized in mitochondria-associated membranes. Taken these data, we speculate that the cellular localization of SUI-family genes is related to its function in diverse biological process, and the localization between SUI-family members could differ.

- The genetic characterization of some revertants identified three unlinked suppressor loci: SUI1, SUI2 and sui3, which when mutated restored the expression of the HIS4 allele despite the absence of the AUG initiator codon. Both sui1 and sui2 are recessive and cause temperature-sensitive growth on enriched medium. The temperature-sensitive phenotype and the ability to restore HIS4 expression associated with either sui1 or sui2 mutations cosegregate in crosses. SUI3 mutations are dominant and do not alter the thermal profile for growth. None of the mutations at the three loci suppresses known frameshift, missense or nonsense mutations. Each is capable of suppressing the nine different point mutations of the initiator codon at HIS4 or HIS4-lacZ as well as a two base change (ACC) and a three base deletion of the AUG codon, suggesting that the site of suppression resides outside the normal initiator region. sui1 and sui2 suppressor mutations were mapped to chromosomes XIV and X, respectively. Suppression by sui1, sui2 and SUI3 mutations results in 14-, 11- and 47-fold increases, respectively, relative to isogenic parent strains, in the expression of a HIS4 allele lacking the initiator AUG codon. Part of this increase in the HIS4 expression by sui2 and SUI3 can be attributed to increases of HIS4 mRNA levels, presumably mediated by perturbation of the general amino acid control system of yeast.
