Distribution of cis-Acting Element Families Important in Ethylene Biosynthesis and Signaling in Putative Soybean Promoters. The diagram corresponds to the number of possible soybean promoters and the number of cis-acting elements present in each group analyzed: ethylene biosynthesis and signal transduction. The line thickness is directly related to the contribution of each family of cis-acting elements in each group: the thinnest lines correspond to the fewest number of elements and putative promoters that have them, and the thickest line corresponds to the highest number of elements and putative promoters that have them. ABRE - ABA response elements; AREF - auxin response elements; BRRE - brassinosteroid response elements; CE1F - coupling elements 1 binding factors; DREB - dehydration responsive element binding factors; EINL - ethylene insensitive 3 like factors; EREF - ethylene response element factors; GCCF - GCC-box family; JARE - jasmonate response elements
