Abiotic stress tolerance of transgenic plants overexpressing CBFs
Gene | Transgenic plant | Stress tolerance of transgenic plants | References |
---|---|---|---|
AtCBF1/2/3 | Brassica napus | Constitutive overexpression enhanced both basal and acquired freezing tolerance | (22) |
AtCBF1 | Tomato | Constitutive overexpression enhanced oxidative stress tolerance under chilling stress; enhanced tolerance to water-deficit stress | (23, 24) |
AtDREB1A/CBF3 | Tobacco | Transgenic plants expressing RD29A∷DREB1A exhibited enhanced chilling and drought tolerance | (25) |
AtDREB1A/CBF3 | Wheat | Transgenic plants expressing RD29A promoter∷AtDREB1A gene showed delayed water stress symptoms | (26) |
AtCBF3 | Rice | Constitutive overexpression resulted in enhanced tolerance to drought and high salinity and a marginal increase in chilling tolerance | (27) |
AtDREB1A/CBF3 | Maize | RD29A∷CBF3 transgenic plants are more tolerant to cold, drought, and salinity | (28) |
AtCBF1 | Potato | Constitutive or stress-inducible expression of CBF1 or CBF3 but not CBF2 conferred improved freezing tolerance to frost-sensitive Solanum tuberosum | (29) |
OsDREB1 | Arabidopsis | Overexpression in Arabidopsis induced target COR genes and conferred enhanced tolerance to freezing and drought stresses | (30) |
OsDREB1A/B | Rice | Constitutive expression conferred improved tolerance to cold, drought, and salinity | (31) |
ZmDREB1 | Arabidopsis | Overexpression in Arabidopsis induced COR genes and conferred tolerance to freezing and drought | (32) |
BnCBF5 and BnCBF 17 | B. napus | Overexpression led to increased constitutive freezing tolerance, increased photochemical efficiency and photosynthetic capacity | (33) |
