1.A.10.1.10
The homo- and heteromeric glutamate receptor, GLR3.3/3.4 (Desensitized in 3 patterns: (1) by Glu alone; (2) by Ala, Cys, Glu or Gly; (3) by Ala, Cys, Glu, Gly, Ser or Asn (Stephens et al., 2008). A regulatory mechanism underlies Ca2+ homeostasis by sorting and activation of AtGLRs by AtCNIHs (see for example, 8.A.61.1.9) (Wudick et al. 2018).  May be responsible in part for Cd2+ uptake (Chen et al. 2018). GLR3.3 and GLC3.6 (TC# 1.A.10.1.24) (but not GLR3.4) play different roles in nervous system-like signaling in plant defense by a mechanism that differs substantially from that in animals (Toyota et al. 2018). Members of the banana GLR gene family have been identified, and expression analyses in response to low temperature and abscisic acid/methyl jasmonate concentrations have been reported (Luo et al. 2023).
