WebSep 9, 2024 · It is demonstrated that SLAC1 represents the slow, deactivating, weak voltage-dependent anion channel of guard cells controlled by phosphorylation/dephosphorylation. 751 PDF Guard cell anion channel SLAC1 is regulated by CDPK protein kinases with distinct Ca2+ affinities D. Geiger, S. Scherzer, +9 authors … WebSep 1, 2024 · Previous research reported that constitutively active CPK3 could regulate SLAC1 and KAT1, respectively, to control stomatal movement [58,50]. In addition, it could interact with TPK1 and play an essential role in balancing cytosolic K + …

WebSLAC1 encodes a central guard cell S-type anion channel that mediates ABA-induced stomatal closure.Coexpressionof thecalcium-depen- dent protein kinase 21 (CPK21), CPK23, or the Open Stomata 1 kinase (OST1) activates SLAC1 anion currents. However, reconsti- tution of ABA activation of any plant ion channel has not yet been attained. WebOct 25, 2024 · Our results show that GHR1 is a pseudokinase and suggest that CPK3 is an interaction partner of GHR1. We propose that GHR1 acts in stomatal closure via SLAC1 activation mediated by the scaffolding functions of GHR1 involving interacting kinases rather than by direct phosphorylation.

WebCPK3 activated SLAC1 to the same extent as CPK6delEF, while the co-expression of CPK6 wild-type together with SLAC1 revealed anion current with half-maximal amplitude at –100 mV (Figure 1C, left). These results point to the requirement of elevated cytosolic calcium concentrations to activate CPK3 and, in turn, open SLAC1—a feature WebJul 19, 2024 · A similar behaviour is seen with CPK3 and 6, with CPK6 activation of SLAC1 not requiring cytoplasmic calcium elevation, whereas activation by CPK3 does (Scherzer et al., 2012). ... Stomata of the slac1/slah3 double mutant are also insensitive to ABA, which indicates that SLAC1 and SLAH3 mediate the PAMP and ABA-induced guard cell S-type …
WebNov 1, 2012 · To elucidate SLAC1 activation under well-defined Ca 2+ levels, we performed in vitro kinase assays with SLAC1 NT in the presence of CPK3 and 6. A high Ca 2+ affinity was recorded for phosphorylation of the SLAC1 N-terminus by CPK3 (Figure 1E, left), whereas only a weak calcium affinity, on top of a constitutive core activity, was monitored …
