Gene Details:

• Gene ID: Glyma.03G251400
• Gene Symbol: GmPpcK1
• Gene Name: phosphoenolpyruvate-carboxylase kinase1
• Genome: Wm82.a4.v1
• Species: Glycine max

Functional Descriptions:

• Although the GmPpcK1–4 transcripts are all expressed throughout nodule development, only the nearly identical GmPpcK2/3 homologs are nodule-enhanced and up-/down-regulated in vivo by photosynthate supply from the shoots.
• In situ RT–PCR investigation of the spatial localization of the GmPpcK1–4 and GmPpc7 transcripts in mature nodules is entirely consistent with this view.
• Complementary histochemical and related RNA gel-blot findings with nodulated, GmPpcK1/3 promoter::GUS-expressing T2 plants provide direct experimental evidence that (i) PpcK gene expression is controlled primarily at the transcriptional level| and (ii) the contrasting expression properties of GmPpcK1/3 are conferred largely by regulatory element(s) within the approximately 1.4-kb 5′-upstream region.
• As a result of our multifaceted analyses of GmPpcK1–4, GmPpc7 and PEPC-phosphorylation in the soybean nodule, it is proposed that the GmPpcK2/3 homologs and GmPpc7 together comprise the key molecular ‘downstream players’ in this regulatory phosphorylation system within the mature nodule’s central zone.
