WebA cis -acting element for the sulfur response is reported for the Arabidopsis SULTR1;1 sulfate transporter gene ( Maruyama-Nakashita et al., 2005 ). The sulfur-responsive region of SULTR1;1 existed in the 5′-upstream region between − 2777 and − 2762 of its coding sequence. This region was named SURE after sulfur-responsive element. WebApr 7, 2024 · To analyze the cis-acting regulatory elements of BvSUTs, the online program PlantCARE was used to determine the structure of the promoter sequence within the SUT genome (assuming a length of approximately 2 kb upstream of the start codon). This analysis included cis-regulatory elements involved in endosperm expression, cis-acting …
