...ferent abiotic stresses, heat stress has the most devastating impact on plant growth. Heat shock transcription factors are known to play an important role in regulating heat stress in plants. Tobacco (Nicotiana benthamiana) was transformed with heat shock transcription factor HsfA1d by transfecting leaf discs with Agrobacterium strain GV3101 carrying CaMV35S-YFP::HsfA1d construct. After PCR and confocal-based confirmation, ...

Two hundred and seventy broiler chicks were randomly assigned to 6 dietary groups: three dietary groups in thermoneutral temperature (TN) and three dietary groups under high temperature. One group of birds received a basal diet only (control group), second group of birds received a diet supplemented with silymarin at the level of 10g/kg and third group of birds received a diet supplemented with ZnO at the level of 60 ...
