Ascorbate Peroxidase 1 Plays a Key Role in the Response of Arabidopsis thaliana to Stress Combination

Article conducting proteomic and metabolic analysis of Arabidopsis thaliana plants subjected to a combination of drought and heat stress. The authors identify 45 different proteins that specifically accumulated in Arabidopsis in response to the stress combination. The findings suggest that cytosolic APX1 plays a key role in the acclimation of plants to a combination of drought and heat stress.

Mutations in Arabidopsis Fatty Acid Amide Hydrolase Reveal That Catalytic Activity Influences Growth but Not Sensitivity to Abscisic Acid or Pathogens

Article showing that the enhanced growth and NAE tolerance of the AtFAAH overexpressing seedlings depends on the catalytic activity of AtFAAH, hypersensitivity to ABA and hypersusceptibility to nonhost pathogens are independent of its enzymatic activity. Findings suggest that the AtFAAH influences plant growth and interacts with ABA signaling and plant defense through distinctly different mechanisms.
