Oxygen supply is a prerequisite for response to aluminum in cultured cells of tobacco (Nicotiana tabacum).

ABSTRACT: Responses to aluminum (Al) were investigated in tobacco cells (cell line SL) in a calcium-sucrose solution for up to 24 h under shaking (aerobic) condition. Microarray analysis of upregulated and downregulated genes under Al exposure and following Gene Ontology (GO) enrichment analysis of biological process category revealed only one GO term to be enriched for the upregulated genes, "response to chitin," annotated with genes encoding transcription factors (NtERF1 and NtMYB3) and MAP kinase (WIPK), and nine GO terms for the downregulated genes, including "cell wall loosening" and "lipid transport," annotated with genes encoding expansin (NtEXPA4) and lipid transfer protein (LTP)/LTP-like (NtLTP3 and NtEIG-C29), respectively. Al triggered the production of nitric oxide (NO) then reactive oxy
