Gene Details:

• Gene ID: Zm00001eb253580
• Gene Symbol: ZmTMM1 mads26
• Gene Name: MADS-transcription factor 26
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• A maize truncated MIKC-type MADS-box transcription factor (ZmTMM1) lacking K- and C-domains, expressed preferentially in the lateral root branching zone and induced by the localized supply of nitrate.
• The local activation of glucocorticoid receptor fusion proteins for ZmTMM1 and an artificially truncated form of AtANR1 without the K- and C-domains stimulates the lateral root growth of the Arabidopsis anr1 agl21 mutant, providing evidence that ZmTMM1 encodes a functional MADS-box that modulates lateral root development.
• Involvement of a truncated MADS-box transcription factor ZmTMM1 in root nitrate foraging.
• ZmTMM1 reveals its involvement in root nitrate-foraging responses, complementing the function of Arabidopsis ANR1 and AGL21.
• ZmTMM1 is expressed in root xylem parenchyma cells and outer layer cortical cells.
• Ectopic overexpression of ZmTMM1 recovers the defective growth of lateral roots in the Arabidopsis anr1 agl21 double mutant.
