Auxin-induced gene expression in mesocotyl elongation of maize inbred line 3681-4 tolerant to deep-sowing

ABSTRACT: In order to elucidate the molecular mechanism of auxin-induced mesocotyl elongation, gene expression profiling analyses were performed in a deep-sowing tolerant maize inbred line 3681-4. Gene expression studies combing Affymetrix GeneChip analysis and Real-time PCR were employed to determine the molecular mechanism underlying IAA promotion of maize mesocotyl elongation. Under deep-sowing condition, IAA is transported by auxin transporter-like protein 1 and binds to auxin binding protein ABP20, which results in degradation of Aux/IAA and de-repressing of auxin-inducible genes. Then, transcriptional factor such as MYB, kinase such as LRR, fructose and mannose metabolism and so on are activated. Finally, genes involved in cell wall synthesis and modification are expressed so that mesocotyl el
