ProteomicsThe thylakoid lumen Deg1 protease affects non-photochemical quenching via the levels of violaxanthin de-epoxidase and PsbS
Non-photochemical quenching (NPQ), the dissipation of excess light energy as heat, has been long recognized as a major protective mechanism that minimizes the potential for oxidative damage to photosystem II (PSII) reaction centers. Two major positive contributors to NPQ are the carotenoid zeaxanthi...

ProteomicsImperfect Redundancy in the Family of Thylakoid Lumen Deg Proteases in Arabidopsis Helps Identifying Their Potential Substrates
Deg proteases are involved in protein quality control and response to stress in prokaryotic organisms. Out of the 16 Deg-encoding genes of Arabidopsis, the products of three, Deg1, Deg5 and Deg8, are located in the thylakoid lumen. Deg1 forms homo-hexamers, degrading photosynthetic proteins, especia...

ProteomicsArabidopsis leaf senescence
Monitor changes in the proteome of senescing leaves, using protein MS data obtained from the same leaf groups used for imaging. Arabidopsis thaliana mature leaves were grouped according to their chlorophyll content: Dark Green (DG), Green (G), Light Green (LG) and Yellow (Y), containing 100, 45, 25 ...
