5' untranslated region of α-globulin BEN
The 5' untranslated region of the Gossypium hirsutum α-globulin B gene consists of the promotoer (1108 basepairs) and a 5' transcribed, untranslated sequence (36 basepairs) of the gene. The promoter is seed-specific and confined to middle to late stages of embryo development; only active at 15 days post-anthesis, during the cotyledon expansion stage in the developing embryo and increasing thereafter until embryo maturation.Transcripts under transcriptional control of this promoter are found at high levels in the dry seed. In contrast, the promoter is inactive in the stem, leaf, root, pollen, and floral bud tissues. Additionally, water stress does not induce transcriptional activity.
