Auxin binding proteins ABP1 and ABP4 are involved in the light- and auxin-induced down-regulation of phytochrome gene PHYB in maize (Zea mays L.) mesocotyl
Original language description
Previous research in maize suggested a possible involvement of auxin-binding proteins (ABPs) in light signaling during maize seedling development. To obtain more information about the interaction of auxin and light signaling, we investigated the gene expression of phytochrome B (PHYB) and phytochrome A (PHYA) in loss-of-function mutants in ABP1 and ABP4 genes in maize (Zea mays L.). We studied how expression of the PHYB and PHYA genes in mesocotyl is regulated by white light (WL), and whether exogenousauxin NAA influences the expression of the phytochrome genes. We found that knockout of ABP1 or ABP4 results in essentially reduced expression of PHYB gene in dark-grown mesocotyl. WL reduced PHYB expression in WT but not in the ABPs knockout seedlings.The data indicate that ABP1 and ABP4 are positively involved in PHYB expression in etiolated mesocotyl. Our results also indicate that in etiolated mesocotyl, ABP1 and ABP4 mediate the inhibitory effect of exogenous auxin on level of PHYB
