Quantitative proteomics Reveals Targets of Protein Kinase SnRK1 in Arabidopsis under Submergence

Project description:SNF1 RELATED PROTEIN KINASE 1 (SnRK1) is proposed as a central integrator of regulatory pathways in plant stress and energy starvation signaling. We observed in this study that the Arabidopsis SnRK1.1 dominant negative mutant (SnRK1.1K48M) had lower tolerance to submergence than the wild-type, suggesting that SnRK1.1-dependent phosphorylation of target proteins is important in energy starvation signaling triggered by submergence. To gain further insight into submergence signaling mechanisms, we determined the temporal response to energy starvation through AMP/ATP quantification and used quantitative phosphoproteomics to compare the global changes in phosphopeptides in Col-0 and SnRK1.1K48M. We found that the phosphorylation levels of 59 peptides increased and the levels of 96 peptides decreased in Col-0 within 0.5�� h of submergence. Among the 59 peptides with increased phosphorylation in Col-0, 49 did not show increased phosphorylation levels in SnRK1.1K48M under submergence. These proteins are involved in sugar synthesis, glycolysis, osmotic regulation, ABA signaling, protein synthesis and ROS signaling. In particular, the phosphorylation of MAPK6, which is involved in regulating ROS responses under different abiotic stresses, was disrupted in the SnRK1.1K48M mutant. In addition, PTP1, a negative regulator of MAPK6 activity that directly dephosphorylates MAPK6, was also regulated by SnRK1.1. These results reveal insights into the function of SnRK1 and the downstream signaling factors of submergence.

Among the 59 peptides with increased phosphorylation in Col-0, 49 did not show increased phosphorylation levels in SnRK1.1K48M under submergence.

Bisulfite (methylome) sequencing of progenies of Col-0 grafted on msh1; Col-0 grafted on dcl2,3,4,msh1; Col-0 grafted on Col-0; msh1 mutant; dcl2,3,4,msh1 quadruple mutant in Arabidopsis [msh1_graft_BS-seq]

Project description:Col-0 floral stem was grafted on the msh1 mutant (Col-0/msh1); on the dcl2,3,4,msh1 quadruple mutant (Col-0/dcl2,3,4,msh1); on Col-0 (Col-0/Col-0). Seeds were collected from the grafted Col-0 scion after grafts were established. Seed coming from the graft then were grown on the peat mix, leaf tissue was collected at the bolting and used for the bisulfite sequencing (methylome). Tissue from the msh1 mutant and dcl2,3,4,msh1 quadruple mutants used as rootstocks was similarly collected at the bolting stage and used for the bisulfite sequencing.

ChIP-seq for HA-HTR5/Col-0 and Col-0 using HA antibody

Project description:To investigate the deposition of HTR5 in Arabidopsis, we analysed genome-wide HTR5 density in the wild-type Col-0 by ChIP-seq. We then performed HTR5 occupancy analysis using data obtained from ChIP-seq of 3 different plants including HA-HTR5/Col-0 and Col-0. Col-0 acted as negative control.
