B1Raf_Phosphoproteome_Raw_Data

ABSTRACT: (1) Phosphopeptide abundances of group B-Rafs, SnRK2s or SnRK2 substrates in the aerial parts of soil-grown Arabidopsis wild-type (Col-0) seedlings with/without water supply for indicated periods. Data were obtained from three independent biological replicates. (2)Phosphopeptide abundances in 2-week-old Arabidopsis wild-type (Col-0) seedlings treated with/without dehydration on the filter paper for 30 min. Data were obtained from three independent biological replicates. (3) Phosphopeptide abundances in 2-week-old Arabidopsis wild-type (Col-0), raf13-1raf15-1 or ireh1-2 seedlings under optimal growth conditions. Data were obtained from three independent biological replicates.

When plants are exposed to drought stress, there is a trade-off between plant growth and stress responses. Here, we identified a signaling mechanism for the initial steps of the drought-growth trade-off. Phosphoproteomic profiling revealed that Raf13, a B1 subgroup Raf-like kinase, is dephosphorylated under drought conditions. Raf13 and the related B1-Raf Raf15 are required for growth rather than the acquisition of osmotolerance. We also found that Raf13 interacts with B55-family regulatory subu  ...[more]
