Gene Details:
- Gene ID: Pt3g009520
- Gene Symbol: PtrBAM3
- Gene Name: β-Amylase 3
- Genome: Poncirus trifoliata v1.0
- Species: Poncirus trifoliata
Functional Description:
- Demonstrate that dehydration-induced expression of PtrBAM3 in trifoliate orange (Poncirus trifoliata (L.) Raf.) functions positively in drought tolerance via modulation of starch catabolism.
- Two transcription factors, PtrABF4 (P. trifoliata abscisic acid-responsive element-binding factor 4) and PtrABR1 (P. trifoliata ABA repressor 1), were identified as upstream transcriptional activators of PtrBAM3 through yeast one-hybrid library screening and protein–DNA interaction assays.
- PtrABF4 physically interacted with PtrABR1 to form a protein complex that further promoted the transcriptional regulation of PtrBAM3.
- PtrABF4 and PtrABR1 function positively in drought tolerance by regulating PtrBAM3-mediated starch decomposition.
