Illustration of the elements of the structural models of the Gm Hsp 20 gene promoter region. The Cold Stress and Nematode Stress Models were identified using Frameworker/Genomatix. This program was employed to search for the main common elements between genes and the highest frequencies of their positions. In the Cold Stress Model (A), the identified HSEs positioned with a negative orientation have p-values of 0.0381311. The model for the AHBP, GTBX, VTBP (TATAbox vertebrate) and PTBT (TATAbox plant) elements has a p-value 1.67 e-04. The model with a W-box shows a p-value of 5.02 e-01. Another model identified a CAAT box with a p-value of 0.167564. In the Nematode Stress Model (B), the identified HSE position has a p-value of 9.37 e-01. The model with the ABRE, MYBS, MYCL and HEAT cis-elements presented a p-value of 9.57 e-04. Another model, without stabilization of the mandatory elements, included the L1BX, AHBP, GTBX, VTBP and HEAT elements with a p-value of 4.789 e-06. All of the models found for each specific stress were concatenated to form a single representative model.
