Gene Details:

• Gene ID: Glyma.05G121600
• Gene Symbol: GmVTL1a
• Gene Name: vacuolar iron transporter like 1
• Genome: Wm82.a4.v1
• Species: Glycine max

Functional Descriptions:

• GmVTL1a is an iron transporter on the symbiosome membrane of soybean with an important role in nitrogen fixation.
• GmVTL1a and GmVTL1b are members of the vacuolar iron transporter family and homologous to Lotus japonicus SEN1 (LjSEN1), which is essential for nitrogen fixation.
• GmVTL1a transports iron in yeast and restores nitrogen fixation when expressed in the Ljsen1 mutant.
• We conclude GmVTL1a is responsible for transport of iron across the SM to bacteroids and plays a crucial role in the nitrogen-fixing symbiosis.
• GmVTL1a is responsible for transport of iron across the SM to bacteroids and plays a crucial role in the nitrogen-fixing symbiosis.
• GmVTL1 knockout minimally affected soybean growth under nonsymbiotic conditions, but dramatically impaired nodule development and SNF activity under nitrogen-limited and rhizobia-inoculation conditions, which eventually led to growth retardation.
• These results demonstrate that GmVTL1a is indispensable for SNF in nodules as a transporter of ferrous iron from the infected root cell cytosol to the symbiosome.
