Functional Descriptions:

  • Tissue-specific gene expression analysis revealed that OsPM19L1 was highly expressed in the leaf sheath of rice.
  • Interestingly, expression of OsPM19L1 was high at the early stage of panicle development and decreased thereafter.
  • qRT-PCR analysis indicated that OsPM19L1 was dramatically induced by 20% PEG stress (>600-fold), exogenous abscisic acid (>350-fold), salt and cold stress.
  • Thus, OsPM19L1 appears to be closely associated with stress tolerance through ABA-dependent pathway in rice.
  • Characterization of OsPM19L1 encoding an AWPM-19-like family protein that is dramatically induced by osmotic stress in rice.
  • Moreover, under stress conditions, OsPM19L1 expression was enhanced in an ABI5-Like1 (ABL1) deficiency rice mutant, abl1, suggesting that ABL1 negatively regulates OsPM19L1 gene expression.
  • Further investigation revealed that OsPM1 expression is regulated by the AREB/ABF family transcription factor OsbZIP46.
  • Phenotypic analysis of overexpression, RNA interference (RNAi), and knock out (KO) lines showed that OsPM1 is involved in drought responses and seed germination regulation.
  • The AWPM-19 Family Protein OsPM1 Mediates Abscisic Acid Influx and Drought Response in Rice.
  • Our results thus revealed that OsPM1 is an ABA influx carrier that plays an important role in drought responses.
  • In this study, we found that rice (Oryza sativa) OsPM1 (PLASMA MEMBRANE PROTEIN 1), encoded by a gene of AWPM-19 like family, mediates ABA influx through the plasma membrane.
  • 3H-()ABA transport activity and FRET (Fluorescence Resonance Energy Transfer) assays both demonstrated that OsPM1 facilitates ABA uptake into cells.
  • Previous reports have demonstrated that overexpression of OsNAC45 enhances salt and drought tolerance in rice, and that OsNAC45 may regulate the expression of two specific genes, OsPM1 and OsLEA3-1.
