Response of the Chloroplast Proteome to 5× Light Stress in the Wild Type and k1 k3.

(A) Changes in protein mass investments (as determined by NadjSPC) in chloroplasts, PGs, and thylakoids in the wild type and k1 k3. Black bars, the wild type; white bars, k1 k3.

(B) The response of specific PG-localized proteins in the wild type (wt) and k1 k3 before and after transition to increased light intensity. CCD4, AT4G19170; aldo/keto reductase, AT1G06690; ABC1K9, AT5G05200. From three biological replicates, significant genotypic effects were identified by GLEE (P < 0.01; marked with two asterisks). Error bars in (A) and (B) indicate sd.

(C) Enrichment of specific plastid functions for significant (P < 0.01; GLEE) genotypic effects in individual proteins in k1 k3 before and after light stress. Only plastid functions with at least 20 proteins were considered.
