Plant abiotic stress response and nutrient use efficiency (2020, background): “ROS, such as H2O2, O2 –, and 1O2, are produced in chloroplasts and mitochondria during heat stress.”
A protein kinase-phosphatase pair interacts with an ion channel to regulate ABA signaling in plant guard cells (2009, background): “The finding that SLAC1 channel activity was strongly dependent on OST1 coexpression may explain why earlier studies (25, 26) failed to reveal SLAC1 activity in oocytes.”
Abscisic Acid Synthesis and Response (2013, background): “Activity of the slow anion channel encoded by SLAC1 is critical for stomatal closing in response to multiple signals including ABA, CO2, light/dark transitions, Ca2+ and ozone (Negi et al., 2008; Vahisalu et al., 2008).”
Activity of guard cell anion channel SLAC1 is controlled by drought-stress signaling kinase-phosphatase pair (2009, background): “SLAC1 was annotated as a bacteria-like dicarboxylate carrier because of sequence similarities with the yeast MAE1 transporter (27, 28, 35, 36).”
Comprehending crystalline β-carotene accumulation by comparing engineered cell models and the natural carotenoid-rich system of citrus (2011, neutral): “In Arabidopsis, SLAC1 is essential for stomatal closure in response to CO2, and SLAC1-deficient mutants showed constitutively higher stomatal conductance, directly due to larger stomatal apertures (Negi et al., 2008; Vahisalu et al., 2010).”
Guard Cell Signal Transduction Network: Advances in Understanding Abscisic Acid, CO2, and Ca2+ Signaling (2010, background): “slac1 mutant plants are strongly impaired in the high CO2-induced stomatal closure response, illustrating that the SLAC1 protein is a positive mediator of the CO2-induced stomatal closure signaling pathway (128, 190).”
The role of ABA and MAPK signaling pathways in plant abiotic stress responses. (2014, result): “Two independent studies reported SLOW ANION CHANNEL-ASSOCIATED 1 (SLAC1) as the most likely S-type anion channel that triggers membrane depolarization required for stomatal closure (Negi et al., 2008; Vahisalu et al., 2008).”
Abscisic Acid and Abiotic Stress Tolerance in Crop Plants (2016, background): “Two different groups reported that Slow Anion Channel-Associated 1 (SLAC1), is the S-type channel that triggers membrane depolarization required for stomatal closure (Negi et al., 2008; Vahisalu et al., 2008).”
Early abscisic acid signal transduction mechanisms: newly discovered components and newly emerging questions. (2010, background): “SLAC1, identified recently as the S-type anion channel, is a 10-transmembrane domain protein with an extended cytosolic N-terminal region (Negi et al. 2008; Vahisalu et al. 2008) that includes an OST1 phosphorylation site required for channel activity (Geiger et al. 2009; Lee et al. 2009; Vahisalu…”

Response of plants to water stress (2014, background): “SLAC1 (SLOW ANION CHANNEL-ASSOCIATED 1) functions as a major S-type anion channel in guard cells (Negi et al., 2008; Vahisalu et al., 2008), and is activated directly by a Snf1-related protein kinase 2 (SRK2E/OST1/SnRK2.”
ABA signaling in stress-response and seed development (2013, background): “Several membrane proteins were identified as SnRK2 substrates: SLAC1, a slow anion channel, which has a central role in guard cells (Negi et al. 2008; Vahisalu et al. 2008; Geiger et al. 2009; Lee et al. 2009; Chen et al. 2010); KAT1, an inward-rectifying potassium channel, which is also important f”
