Prediction of cis-acting elements on the promoters of the precursor sequences of the Vvi-MIR399 family. (a) Chromosomal localization of the Vvi-MIR399 family members. The scale is in megabases (Mb). (b) Prediction of cis-acting elements on the promoters of the Vvi-MIR399 family. The upper image shows a summary of cis-acting elements in the promoter region of Vvi-MIR399 family members. The image in the middle shows the number of elements contained in the promoters of the Vvi-MIR399 family. The image on the left shows the Vvi-MIR399 family containing cis-acting elements related to three classes, including stress response (marked by a blue line), tissue-specific (marked by a green line), and progress-specific (marked by a red line). The gray, yellow, green, blue, orange, and purple squares indicated 0, 1, 2, 3, 4, and more than 4 promoters, respectively.
