Regulatory motifs found in tomato (S. lycopersicum cv Heinz 1706) corresponding to HSFA1E and HSF21 TFBS associated to heat stress and ripening. (a) Logo of the position weight matrix (PWM) of the found TFBS in tomato and the corresponding known in Arabidopsis for heat stress (upper panels) and for ripening (lower panels). (b) Theoretical distribution of weight scores obtained during the construction of the PWMs of tomato and (c) corresponding decreasing cumulative distribution functions (dCDF) for the found TFBS in tomato: HSFA1E (upper panels) and HSF21 (lower panels), respectively. (d) Location of the HSFA1E (blue-squares) and HSF21 (red-squares) motifs found in the promoter regions (i.e. upstream) of 9 sHSPs of tomato. These genes are also up-regutaled (UP, red triangles) during ripening [14] and are arranged in tandem in chromosomes 06, 08 and 09
