Gene Details:

• Gene ID: Zm00001eb391450
• Gene Symbol: ZmEXPB4 EXPB4 expb17
• Gene Name: beta expansin17
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The ZmEXPB4 gene was down-regulated after treatment with 200 mM NaCl. Hormone treatment induced expression of Exp1 but repressed that of ExpB2 in maize roots. Therefore the differential expression patterns of expansins suggest that each expansin member may play a specific role in root growth and development, and in response to external stimuli.
• Previous work identified four expansin genes highly expressed in the maize roots, namely the two α-expansins, ExpA1 and ExpA5, and two β-expansins, ExpB2 and EXPB4.
• The down-regulation of cell wall related ZmEXPB4 and ZmMHA genes as the duration of exposure was increased.
