WebAug 24, 2024 · Along with bacterial-induced auxin biosynthesis, the induction of cytokinin biosynthesis by Agrobacterium results in cell proliferation and the formation of galls. Metabolites needed for gall tumor growth are then rerouted from host plant source leaves to the crown gall tumor, which becomes a strong sink (reviewed in Gohlke and Deeken, 2014). WebDec 4, 2024 · For example, upregulation of SHY2 by cytokinin will act to inhibit auxin signaling (links 48, 64, and 65 in Supplemental Table 1) while degradation of SHY2 by auxin increases cytokinin biosynthesis (links 61, 66, and 46 in Supplemental Table 1). SHY2 therefore plays a complex regulatory role in both the cytokinin and auxin signaling …
