Overview of subcellular localization of soybean salt tolerance genes at cellular level. Light and dark green boxes indicate cation and anion transporters. respectively. CLC, chloride/proton exchanger or chloride channel; CHX, cation/H⁺ exchanger; NDH, subunit of NAD(P)H dehydrogenase complex; NHX, SOS (Salt Overly Sensitive), Na⁺/H⁺ exchanger. Genes involve in regulation of oxidative balance are colored in red. GmCOL1a, CONSTANS-LIKE 1a protein; GmLEA and GmP5CS are downstream target genes of GmCOL1a. GmPAP3, purple acid phosphatase 3; GmPP2A-B’71, B” subunit of phosphatase 2A; GmUCB2, ubiquitin-conjugating enzyme. Genes involve in cell wall remodeling are shown in brown. GmCrRLK1L20, Catharanthus roseus RLK1-like protein; GmDNAJC7, co-chaperone DNAJ protein; GmRD22, BURP-domain protein. Transcription factors are indicated in purple. bHLH, basic/helix-loop-helix protein; bZIP, basic leucine-zipper; DREB, dehydration responsive element-binding proteins; ERF, ethylene-responsive factors; MYB, MYB transcription factors; NAC, NAC (NAM, ATAF, CUC) transcription factors; WRKY, WRKY transcription factors; TFs, other transcription factors. Blue boxes indicate genes involve in signal transduction. GmCam4, calmodulin; GmCBL1, GmCBL4, calcineurin B-like protein; GmCBP60A-1, calmodulin-binding protein; GsCBRLK, calcium-dependent calmodulin-binding receptor-like kinase; GmCDPK3, calcium-dependent protein kinase; GmCIPK2, GmCIPK21, GmPKS4, calcineurin B-like protein interacting kinase; GmCML27, calmodulin-like protein. GmDi19-5, drought-induced protein; GmFBX176, F-box protein; GmMMK1, mitogen-activated kinase; GmNARK, nodule autoregulation receptor kinase; GmPUB21, U-box E3-ubiquitin ligase; GsRLCK, receptor-like cytoplasmic serine/threonine protein kinase; GmSAP16, stress associated protein; GmSK1, S-phase kinase-associated protein 1; Gs5PTase8, inositol polyphosphate 5-phosphatase
