WebSep 9, 2024 · Recently, the Protein Phosphatase 2A (PP2A) complex was found to be one of the mediators involved in the phosphorylation of auxin efflux carrier PIN-FORMED2 (PIN2) that is modulated by SA signalling (Michniewicz et al ., 2007; Tan et al ., 2024 ). WebJan 5, 2024 · PIN2 deployment in the cortex represents a mechanism for fine-tuning the flow of auxin as required for optimal responses within the zone of root elongation. Cold stress inhibits the intracellular trafficking of auxin efflux carrier PIN2. NOV is required for PIN2 polarity in the root cortex.
PIN phosphorylation is sufficient to mediate PIN …
WebJan 20, 2015 · Root gravitropism has been long associated with PAT. The agravitropic pin2 phenotype along with the polarized localization of PIN2 in the root ( Müller at al., 1998) identified PIN2 as the PAT component of root gravitropic response. WebIn Arabidopsis, PIN1, PIN2, PIN3, PIN4, and PIN7 have a longer loop (ranging in size from 298 to 377 amino acid residues), PIN5 and PIN8 have a shorter loop (27–46 residues), and PIN6 contains an intermediate form ( Ganguly et al., 2010; Krecek et … myrtle beach time share presentation
How plants adapt their root growth to changes of nutrients
Webpin2 agravitropic root mutants are conditional and nutrient-sensitive. Nutrients composition modulates auxin response at the root apex. Asymmetry of PIN1 ectopic expression in … WebMar 23, 2024 · The auxin sink in the root cap contributes to the asymmetric auxin distribution in reoriented roots . Polar localization of PIN2 in the plasma membrane of the lateral root cap and epidermal cells directs the auxin flow toward the cortical and epidermal cells [34,35]. Any auxin asymmetry leads to differential growth in the elongation zone . WebMar 25, 2015 · PIN2 is expressed mainly in the epidermis and cortex in the root meristem, with an apical and lateral subcellular localization on the plasma membrane.
