Annotated Information

Function

Please input function information here. Transcription factor IDEF1 early response to iron deficiency in rice necessary to express the late vegetative stage embryos while rich protein gene induction. Higher plants by regulating the expression of genes related to iron to maintain the plants get iron homeostasis of body iron content. IDEF1 to adjust the response of rice to iron deficiency by identifying the response CATGC sequence cis-elements IDE1. Medium to induce the expression of iron-deficiency treatment IDEF and suppress the expression of the two types of transgenic plants was found, and induce the expression of plant IDEF1 compared to suppress the expression of plant IDEF1 early iron deficiency is very sensitive.

Expression

Please input expression information here.IDEF1 cDNA full length 1704bp, contains nine exons and encodes a transcription factor of 362 amino acids, B3 domain-containing products. IDEF1 ABI3/VP1 is a plant-specific transcription factor protein, with the iron deficiency response cis-elements IDE1 the CATGC sequence binding. In the early treatment of iron deficiency, IDEF1 expression of these genes by binding to iron absorption and utilization of the relevant gene promoter elements regulate the CATGC mediated early plant response to iron deficiency (Kobayashi et al., 2007 & 2009).By IDEF1 regulate gene promoter also contains the necessary regulation of gene expression in seed maturation cis-elements CATGCA. Some late embryogenesis abundant protein coding genes such as Osem, their expression in iron plant roots and / or leaves are induced, while expression is dependent on IDEF1, described IDEF1 in the regulation of seed maturation-related genes in vegetative organs of iron deficiency Expression function (Kobayashi et al., 2009).IDEF1 involved in the regulation of gene expression induced by Fe deficiency by, for maintaining the body's balance Fe plays an important role. IDEF1 histidine - arginine and proline-rich region of direct binding of divalent metal, balanced feel of metal ions in the cell (Kobayashi et al 2012.).
