WebAs evidenced by the loss- and gain-of-function analysis, the complex function of PIN6 in auxin transport and homeostasis is required for auxin distribution during lateral and adventitious root organogenesis and for progression of these developmental processes. These results illustrate a unique position of PIN6 within the family of PIN auxin ... WebAuxin Homeostasis. Much of the auxin found in the plant is stored as conjugates to amino acids or sugars (Woodward and Bartel 2005). Auxin can also be produced by β oxidation of indole-3-butyric acid (IBA). These processes are thought to occur in monocots and some genes controlling the process have been identified.
WebMar 17, 2024 · Therefore, auxin homeostasis (biosynthesis and conjugation) and AG level might form a regulatory loop to precisely govern floral organ development. Conclusions. In this study, we have demonstrated that the auxin-responsive gene RhARF18 controls petal–stamen specification by directly suppressing expression of the C-class gene RhAG. WebJan 27, 2024 · Thus, soil nitrogen deficiency also affects plants' endogenous auxin homeostasis . Tian et al. evaluated the effect of fertilization with increasing nitrate concentrations on root architecture, endogenous nitrogen content, and endogenous auxin content in maize plants. Nitrates inhibited root growth, and this was due to a decrease in …
