A chromosome-level annotated draft genome of Sophora japonica is presented. Lei 2022

Three plastid regions were used to reconstruct the phylogenetic relationships and divergence times in the Cladrastis clade, which includes the Styphnolobium genus, of the Fabaceae. Discussed the evolution of morphological characters and biogeographic history. Duan 2020

Presented the complete Sophora japonica chloroplast genome. Shi 2019

Determined the complete nucleotide sequence of the mitochondrial genome of S. japonica 'JinhuaiJ2', the most widely planted variety in Guangxi region of China. Shi 2018

Transcriptomics of Sophora japonica revealed 135 unigenes involved in the biosynthesis of isoflavones. [Article in Chinese] Pan 2018

Differential expression analysis and NR function prediction of the Sophora japonica transcriptome revealed 18 differentially expressed unigenes associated with 13 enzymes in flavonoid biosynthetic pathways. Zhang 2017

Quantified the genetic variation of thirty-four Styphnolobium japonicum varieties using sequence-related amplified polymorphism markers. The genetic variation was relatively narrow. Sun 2016

Developed a rapid method to extract DNA, using an alkaline lysis buffer, and applied to extract DNA from Sophora japonica. [Article in Chinese] Zheng 2014

Perdformed RNA sequencing of S. japonica transcriptome to produce large expression datasets for functional genomic analysis. Annotate unigenes through NCBI BLAST procedure. Predicted an interaction network of unigenes in S. japonica. Zhu 2014

The A1b defense peptide family isolated from members of the Papilionoideae, may have evolved late in the legume lineage from Styphnolobium japonicum or another member of the sophoroid group. Louis 2007

Styphnolobium japonicum, a woody, non-nodulating papilionoid legume, exhibits putative early nodulin 2 genes. Evaluated gene expression dynamics with and without elicitors, as well as the relationship to other basal non-nodulating woody legumes. Foster 2000

Isolated the cDNA clones of the genes encoding bark and seed lectins from Sophora japonica and analyzed and annotated their sequences. Damme 1997
