But their juxtaposition would produce a critical breakthrough for our understanding of life'-namely, the concept of an 'operon,' a cluster of genes whose expression is regulated by an adjacent regulatory gene.
This study was conducted to evaluate the role of GA on the rice performance under saline conditions and to investigate its effects on regulatory gene expression by GA-mediated seed priming.
107-109) Although the ascidian genome lacks an ortholog of Wnt1, the ascidian brain is regionalized by the regulatory gene circuit controlled by Fgf8/ 17/18 expressed at the late gastrula stage, (24) as we described above (Fig.

Agriculture and Agri - Food Canada (Canada) has patented the use of a regulatory gene Lc and encoded protein to alter the biosynthesis and accumulation of flavonoids including anthocyanins and condensed tannins in plants and plant tissues, particularly in alfalfa, white clover, and other forage legumes which are similar in lacking native condensed tannin accumulation in leaves.
FoxA1 therefore should be studied in more detail in experimental systems and animal models as it may be a major growth regulatory gene in luminal type breast cancer.
