Analysis of LCYb1 promoters from various citrus species. (A) Schematic representation of promoter structure of LCYb1 from four citrus species. Green lines represent the coding sequences of LCYb1 genes. Red lines represent the promoter sequences of LCYb1. Gray lines represent the inserted large fragment. The inserted position and fragment size are indicated. Yellow rhombuses represent the 20 bp enhancer elements. (B) SSR screening of different LCYb1 promoters from various citrus varieties. Numbers on the left denote the three electrophoretic bands. Four citrus species including pummelo, grapefruit, sweet orange and mandarin were detected. W, White-flesh Guanxi pummelo; R, Red-flesh Guanxi pummelo; Ht, Huanong red pummelo; H, HB pummelo; S, Star Ruby grapefruit; M, Marsh grapefruit; F, Flame grapefruit; Hq, Washington navel orange; Ca, Cara Cara navel orange; AL, Anliu sweet orange; HAL, HongAnliu sweet orange; B, Bendizao mandarin; I, Qingjiang ponkan; MJ, Mangshan wild tangerine.
