  • Key message
    • The results of northern blot hybridization experiments showed that the transcript of the OsEBP-89 gene accumulates primarily in immature seeds, roots, and leaves (low levels)
    • Expression of OsEBP-89 was induced in roots of rice seedlings by treatment with ACC, NaCl, or 2,4-D
    • Collectively, these results suggest that the OsEBP-89 gene is a new member of the EREBP subfamily and may be involved in ethylene-dependent seed maturation and shoot development of rice
    • In this paper, we describe the cloning and characterization of a rice gene, OsEBP-89, encoding a protein 326 amino acids long with a typical EREBP domain; this is the first report of an EREBP transcription factor in a monocotyledonous plant
    • The OsEBP-89 gene of rice encodes a putative EREBP transcription factor and is temporally expressed in developing endosperm and intercalary meristem
    • OsEBP-89 gene encodes an ethylene responsive element binding protein (EREBP) transcription factor from rice (Oryza sativa)
    • Expressional analysis of an EREBP transcription factor gene OsEBP-89 in rice
    • Northern blot analysis revealed that OsEBP-89 was expressed in root, stem, seeds, flowers and leaves of rice
    • Histochemical assay showed that GUS expressed mainly in phloem of vascular tissues of the root and stem transition region (RST), basal part of sheath roots, stem node and basal part of adventitious roots, also in endosperm of seeds in transgenic rice harboring OsEBP-89/GUS construct (pNSG)
    • Two cis-acting elements, an endosperm motif and a primary PERE, are present upstream of the OsEBP-89 coding region and may be involved in regulating its expression
