Source Description
UniprotDEVELOPMENTAL STAGE: Expression levels gradually decrease with aging in both the shoot and root vasculature. {ECO:0000269|PubMed:16813575}.
UniprotTISSUE SPECIFICITY: Mainly expressed in the endodermis, the gravity-sensing tissue in inflorescence stems. Mostly present in stems and flowers, and, to a lower extent, in seedlings, hypocotyls, roots and the shoot apical meristem (SAM). {ECO:0000269|PubMed:16813575}.

Source Description
TAIRMay be involved in an early event in shoot gravitropism such as gravity perception and/or a signaling process subsequent to amyloplast sedimentation as a putative transcription factor in gravity-perceptive cells.
UniProtTranscription factor involved in inflorescence stems gravitropism, probably by regulating starch accumulation in amyloplasts of graviperceptive cells. Required for stem circumnutation movements. Regulates lateral organ morphogenesis and gravitropic responses (PubMed:24039602). Acts cooperatively with IDD16 to control silique and branche orientation (PubMed:24039602). Involved in the establishment of auxin gradients through the regulation of auxin biosynthesis and transport (PubMed:24039602). {ECO:0000269|PubMed:16813575, ECO:0000269|PubMed:18259878, ECO:0000269|PubMed:24039602, ECO:0000269|PubMed:9210330}.

  1. SGR5 may be involved in an early event in shoot gravitropism such as gravity perception and/or a signaling process subsequent to amyloplast sedimentation as a putative transcription factor in gravity-perceptive cells. [SGR5]
    [PMID: 16813575]
  2. Loss of SGR5 regulatory activity affects starch accumulation in Arabidopsis shoot tissues and causes decreased sensitivity to gravity and diminished circumnutational movements.
    [PMID: 18259878]
  3. The thermoresponsive alternative splicing of SGR5 is proposed to provide an adaptation strategy by which plants protect the shoots from hot air under high temperature stress in natural habitats.
    [PMID: 26256266]
  4. the identification of INDETERMINATE DOMAIN15 (IDD15) and INDOLE-3-ACETIC ACID 17 (IAA17) in Arabidopsis that interacted with ZAT6 in vivo provided new insight of ZAT6-mediated auxin signaling. Further investigation showed that ZAT6 repressed the transcription activation of IDD15 on the YUC2 promoter
