AUXIN BINDING PROTEIN 4 is involved in the Ca2 /auxin-regulated expression of ZCAX3 gene in maize (Zea mays)
Original language description
As a second messenger, calcium is involved in auxin signaling, and previous studies demonstrated that Arabidopsis CAX1 (Ca2+/H+ exchanger) is involved in the auxin transduction pathway. This study was performed to investigate the possible role of auxin-binding proteins ABP1 and ABP4 in Ca2+/auxin-regulated growth in maize (Zea mays L.). We identified and cloned two AtCAX1 homologs in maize, ZCAX2 and ZCAX3. Using maize loss-of-function abp1 and abp4 mutants, the role of ABPs in Ca2+-dependent growth andin the Ca2+/auxin-regulated expression of the CAX genes was investigated in etiolated maize seedlings. Exogenous Ca2+ enhanced mesocotyl but not coleoptile growth in WT, abp1, abp4, and abp1/abp4 mutants, but the maximum stimulation was in abp4. As well, in the abp4 mutant, maximum accumulation of Ca2+ was observed when seedlings were exposed to exogenous Ca2+. In the mesocotyl of abp4 and double mutants, the expression of ZCAX3 was significantly reduced in the absence of exogenous Ca2+
