PAG 2015 Plant Reactome Overview Pathway Curation Orthology Projections New software platform
PAG 2015 Plant Reactome: Overview What is Plant Reactome? Curated metabolic & regulatory pathways in rice and Arabidopsis Orthology projections to 33 other plant species, including maize and several other Oryza species Gene expression overlays, visual species comparisons, other analysis tools (ongoing development)
PAG 2015 Reactome data model Depicts biological processes as a set of connected reactions and events It can represent many events and states in biological processes In addition to classical biochemical reactions, changes in state, such as binding, activation, translocation and degradation can be represented Reactions are connected to form pathways Plant Reactome: Overview

PAG 2015 Orthology Projections
PAG 2015 Orthology Projections Projections from O.sativa to 33 species using Reactome “orthology inference” software Data sources :: Methods Ensembl Gramene – 27 species (monocots and dicots) :: Compara Published leaf tissue transcriptomes – 6 add’l Oryza taxa :: InParanoid clustering Prepared orthology mapping files using custom Python script “Incomparanoid”
PAG 2015 Orthology projections Homologs of taxa listed in green are generated via Inparanoid clustering. * Data from sequenced transcriptome Relative projection “saturation”: Blue is highest, red lowest, with yellow marking the intermediate. ^Projections currently exclude cell-cycle pathways SpeciesPathwaysReactionsGene Products Oryza sativa japonica Nipponbare (curated reference) 238^ Arabidopsis thaliana Brassica rapa Glycine max (soybean) Medicago truncatula Populus trichocarpa Prunus persica (peach) Solanum lycopersicum (tomato) Solanum tuberosum (potato) Triticum aestivum (wheat ABD-genome hexaploid) Triticum urartu (wheat A-genome) Aegilops tauschii (wheat D-genome) Hordeum vulgare (barley) Setaria italica (foxtail millet) Brachypodium distachyon Oryza rufipogon Oryza nivara Oryza sativa Indica (93-11) Oryza sativa aus Kasalath Oryza glumaepatula Oryza barthii Oryza glaberrima Oryza longistaminata * Oryza meridionalis Oryza punctata Oryza minuta * Oryza officinalis * Oryza australiensis * Oryza granulata * Oryza brachyantha Leersia perrieri Sorghum bicolor Zea mays Musa acuminata (banana)

PAG 2015 Pathway Curation
PAG 2015 Ongoing rice curation Currently >200 curated rice pathways Notable signaling pathways in recent releases: Auxin signaling Brassinosteroid signaling
PAG 2015 Arabidopsis curation Converted AraCyc 11 data was merged into Reactome’s main curation database Arabidopsis curation began in March 2014 Curation, beyond describing pathways not found in other databases, focuses on updating pathway data to reflect most recent literature To date, ~70 curated A.th. pathways in the central database (…and counting)
