Expression and Functional Analysis of a Novel Group of Legume-specific WRKY and Exo70 Protein Variants from Soybean.

ABSTRACT: Legumes fix atmospheric nitrogen through symbiosis with microorganisms and contain special traits in nitrogen assimilation and associated processes. Recently, we have reported a novel WRKY-related protein (GmWRP1) and a new clade of Exo70 proteins (GmExo70J) from soybean with homologs found only in legumes. GmWRP1 and some of the GmExo70J proteins are localized to Golgi apparatus through a novel N-terminal transmembrane domain. Here, we report further analysis of expression and functions of the novel GmWRP1 and GmExo70J genes. Promoter-GUS analysis in Arabidopsis revealed distinct tissue-specific expression patterns of the GmExo70J genes not only in vegetative but also in reproductive organs including mature tissues, where expression of previously characterized Exo70 genes is usually absen
