What is new in PPDB:

2008

• switch the database to Arabidopsis genome annotation v8 - MS/MS data used for the PLOSONE paper are all researched against v8
• incorporation of a large scale chloroplast proteome analysis of Arabidopsis - this includes subcellular location and post-translational modification analysis (published in PLOSONE, Zybailov et al.)
• experimental data on the comparative analysis of maize bundle sheath and mesophyll membrane proteomes available - published in (Majeran et al., 2008).

2007

• The name of PPDB is changed to Plant Proteome Database

2006

• We have captured data from 58 proteomics publications (Arabidopsis and Brassica ). The data set have been deposited into PPDB.
• newly curated location based on experimental evidence for hundreds of plastid proteins, including nucleoids, ribosomes, and plastoglobules.
• new experimental output parameters: experimental sequence coverage from internal MS data, subcellular localization based on GFP/YFP for >1000 proteins - from the SUBA database. 
•  experimental protein sequence coverage display by internally mass spectrometry data (via 'pop-up' windows on each protein page report). - experimental MS/MS data on the peripheral and lumenal proteome of A. thaliana - published in (Giacomelli et al., 2006).
• experimental data on the plastoglobule proteome of A. thaliana available - published in (Ytterberg et al., 2006).
• Arabidopsis gene models are updated to TAIR v6.0. All MS/MS-based proteins identifications published since summer 2004 are reanalyzed against v6.0.

• experimental data on the oligomeric stromal proteome of A. thaliana available- published in (Peltier et al., 2006).
• experimental data on the comparative analysis of maize bundle sheath and mesophyll chloroplast proteome available - with unique display of comparative quantitative information on each protein report page - published in (Majeran et al., 2005).

• Arabidopsis: TAIR v8.0
• Maize: AZM v4.0 & ZmGI v16.0 (from TIGR)
