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.
1 tk, a gene that encodes thymidine kinase, an enzyme that phosphorylates the nucleoside analog ganciclovir. 2  DNA polymerase fails to discriminate against the resulting nucleotide and inserts this nonfunctional nucleotide into freshly-replicating DNA. 3  So ganciclovir kills cells that contain the tk gene.f the replacement gene (A* in the diagram) is nonfunctional (a null allele), mating of the heterozygous transgenic mice will produce a strain of  knockout mice  homozygous for the nonfunctional gene (both copies of the gene at that locus have been knocked out).
