A Novel NAC-Type Transcription Factor, NAC87, from Oilseed Rape Modulates Reactive Oxygen Species Accumulation and Cell Death

We describe the characterization of one novel NAC gene, BnaNAC87, which could induce reactive oxygen species overaccumulation and cell death by modulating ROS- and cell deathrelated gene expression

Scholarcy highlights

  • Selective death of cells is essential for plant growth, development and survival
  • Based on expressed sequence tags, BnaNAC87 cDNA was cloned from oilseed rape through reverse transcription–PCR
  • The results demonstrated that transcript levels of NbCAT3, NbGPX2, NbGST1, NbSOD and NbAOX1a were prominently increased, with an average of 1.9- to >100fold higher in leaf tissue expressing BnaNAC87 compared with GUS, at one or more time points
  • We described the functional characterization of a BnaNAC87 Transcription factors gene isolated from oilseed rape, one of the most important oil crops in China and world-wide
  • The role of BnaNAC87 in inducing programmed cell death was confirmed by nuclear DNA fragmentation
  • Our work has clearly demonstrated that BnaNAC87 is a novel member in the family of NACs that modulates reactive oxygen species accumulation and cell death
