Tolerance to drought and salt stress in plants: Unraveling the signaling networks (2014, background): “According to accepted concepts, in Arabidopsis GA signaling is mediated by binding of GA to GID1a/b/c that are GA receptor orthologs of the rice GA receptor gene OsGID1 (GA INSENSITIVE DWARF 1; Ueguchi-Tanaka et al., 2005; Griffiths et al., 2006; Feng et al., 2008).”
Abscisic acid and the control of seed dormancy and germination (2010, background): “The SnRK2s become active when they are de-repressed from their inhibition by PP2Cs (Fujii et al., 2009; Umezawa et al., 2009).”
Comprehending crystalline β-carotene accumulation by comparing engineered cell models and the natural carotenoid-rich system of citrus (2011, neutral): “…respiration, and nitrogen metabolism, as well as a reduction in water and mineral uptake (Ouzonidou et al. , 1997; Perfus-Barbeoch et al. , 2000; Shukla et al. , 2003; Sobkowiak and Deckert, 2003). defect, which is rescued by application of Fe, indicating that IRT1 is the major transporter…”
The role of ABA and MAPK signaling pathways in plant abiotic stress responses. (2014, background): “kinase activities are observed in PP2C loss-of-function or knockout mutants (Umezawa et al., 2009; Vlad et al., 2009).”
Abscisic acid dynamics, signaling and functions in plants. (2019, background): “…CIPK23 in Arabidopsis and MdCIPK22 in apple, affecting phosphorylation changes of multiple downstream regulators (Guo et al. 2001; Boudsocq et al. 2007; Ho et al. 2009; Lin et al. 2009; Mehlmer et al. 2010; Umezawa et al. 2013; Wang et al. 2013; Ding et al. 2015; Ding et al. 2018; Ma et al. 2018).”
Hormone crosstalk in plant disease and defense: more than just jasmonate-salicylate antagonism. (2011, background): “Recent discoveries revealed the role of PYRABACTIN (4-bromo-N-1/2pyridin-2-yl methyl_naphthalene-1-sulfonamide) RESISTANCE (PYR)/REGULATORY COMPONENT OF ABA RECEPTOR (RCAR) proteins, which form a family of cytosolic ABA receptors commonly known as PYLs (PYRABACTIN RESISTANCE LIKE) (41, 78, 115, 142,”
Abscisic acid: emergence of a core signaling network. (2010, background): “Recent work from two groups has taken these observations much further and demonstrated that, in the absence of ABA, PP2Cs directly inactivate SnRK2 kinases by dephosphorylating multiple residues in the kinase activation loop (Umezawa et al 2009; Vlad et al; both in press).”
ABA signal transduction at the crossroad of biotic and abiotic stress responses. (2012, background): “More recent studies have established several SnRK2–PP2C interactions that clearly function in ABA signalling (Yoshida et al. 2006a; Fujii et al. 2009; Lee et al. 2009; Umezawa et al. 2009; Vlad et al. 2009).”
The Role of Stress-Responsive Transcription Factors in Modulating Abiotic Stress Tolerance in Plants (2020, background): “When plants are exposed to abiotic stress, ABA biosynthesis is promoted, resulting in formation of the PYR/PYL–PP2C complex, which inhibits PP2C activity, thus activating SnRK2s to phosphorylate and activate ABFs [30] (Figure 1).”
Molecular Basis of the Core Regulatory Network in ABA Responses: Sensing, Signaling and Transport (2010, background): “Fujii and Zhu (2009) and Umezawa et al. (2009) also reported that a large part of the ABA-activated protein kinase activities are eliminated in the srk2dei mutant, and the expression of the examined ABAinduced genes is completely blocked in the triple mutant.”
