Conclusions, Annotation
Annotation is good enough for gene family/pathway captains to start manual
annotation now.
All data will revolve around iTAG annotation-Suynchronization of SGN, MIPS
and CAB essential
Only tweaking will be needed to adapt main conclusions to final annotation
Manual annotation will be both hypothesis-driven and data-driven.
Hypothesis-driven: Gene families/pathways important for tomato biology
(carotenoid genes, ethylene receptors, etc)
Data-driven: Focus will be on genes-gene families showing:
Unexpected expansion/reduction
Fruit-specific expression
Specific to tomato (by OrthoMCL)
Annotation jamboree will be organized on an island after paper submission
Conclusions, Transcriptomics
Illumina and 454 RNAseq data are being aligned on genome.
Gene models supported by Illumina data have been provided to Affy for chip
design
Protocol has been worked out for polishing 454 data before submission
Evidence for alternative splicing
Inclusion of tissue-specific RNAseq data is important for biological
conclusions on the paper
Cluster of companion papers under production
Inclusion of peptide data on Gbrowse is important and innovative
Task division
Blast Arabidopsis proteins significantly longer from tomato ones to
scaffolds: Rombauts
Study genome duplication: Rombauts (Paterson)
Building pseudomolecules, physical mapping: Sato, Arizona, Keygene
Feed peudomolecules to assembly, assembly correction: van Ham
Chromosome heatmaps/Repetitive element annotation/ FISH pictures:
Chiusano, Gundlachs, De Jong
OrthoMCL clusters: Spannagl
Human Readable Descriptions, Dendrograms: Allab
Enrichment analysis: Not assigned
Collection of RNAseq data: Giuliano
Alignment of 454, Illumina and SOLID data: Filippis, Rombauts, Alioto
Generation of alternative splicing annotation: Rombauts, Fei
Inclusion of peptide data on genome browser: Zouine, SGN, MIPS
Inclusion of BAC ends on genome browser: Datema
Align old array probes on genome annotation: Fei
Data-driven manual annotation
Look for expanded-contracted orthoMCL groups.
Look for tomato-specific orthoMCL groups.
Verify if they are supported by expression data
Look for fruit-expressed genes
Identify appropriate gene family/pathway captains
Hypothesis-driven manual annotation

ARFs: Bouzayen
Carotenoid biosynthesis, photomorphogenesis: Giuliano
Ascorbate: Botella
Transcription factors: Chiusano, Fei,Khurana
R genes: Ercolano, others?
Cyt p450s: Bishop
Repeats: Gundlach
miRNA prediction: Rombauts
