WebApr 12, 2024 · All miRNAs were shown to regulate the gene expression in signal transduction; however, the circadian rhythm was controlled by miR-1-3p, miR-206 and miR-494 through their respective target genes. It is inferred that all prominent MFs and important BPs imperative in CKD were organized by no less than three miRNAs ( Figure 5 B). WebProtein phosphatases (PPs) control a large number of signaling processes in plants, and their inhibition disrupts many cellular processes, leading to death. Endothall (Fig. 5) inhibits one family of PPs, the serine/threonine PPs and it is the only PP inhibitor herbicide.
