Identifying plant diseases is the first step in treating the problem. There are many types of diseases that affect garden plants, leaving many gardeners scratching their heads. By using the following information, you can learn how to go about identifying plant diseases for effective disease control.
ATM, a gene known to be involved in DNA repair and cell cycle control, plays a role in the effect of metformin upstream of AMP-activated protein kinase, and variation in this gene alters glycemic response to metformin.
In the DNA of E. coli, there is a fourth gene, the regulator gene, lacI. The regulator gene is under separate transcriptional control from the other three genes. lacI codes for a protein called a repressor.The repressor binds to a region just before the lacZ gene. mutant regulator gene (lacI -) produces a defective repressor that cannot bind to the operator. A mutant operator region (lacO c) is defective in that the repressor cannot bind and thus transcription cannot be shut off. Both types of mutants have the same constitutive phenotype.
