The Gramene project (www.gramene.org) team is pleased to announce its release #48b highlighting the new version of Plant Reactome database (http://plantreactome.gramene.org/).

In this release the Plant Reactome database has expanded gene homology-based pathway projections to 58 plant species.

Notable newly projected species include wild ancestors of peanut, common bean (Phaseolus), chickpea, pigeonpea, cacao, Brassica oleracea, capsicum pepper, sweet orange, coffee, cotton, grape, date palm, Triticum turgidum (wheat BB), basal angiosperm Amborella, the gymnosperms Norway spruce and Loblolly pine, lower plants Physcomitrella and Selaginella, and green algae Chlamydomonas, to name a few.

In addition, we have added two new hormone signaling pathways from rice for salicylic acid and jasmonic acid and revised three previously curated pathways for Salicylic acid biosynthesis, Brassinosteroid signaling and Strigolactone signaling.

The Plant Reactome database continues to provide its users following features:

* Tutorial https://www.youtube.com/watch?v=YUXH9IIpnSU

* Search and browse pathways, reactions, compounds and gene products

* Data analysis tools

   *-Visualization of omics data

   *-Inter-species pathway comparison

*Advanced search features built on the Apache Solr platform

* RESTful API for programmatic access to Plant Reactome data

The Gramene database project is supported by an NSF award (IOS-1127112).

Intellectual and infrastructure support for the Plant Reactome is provided by the Human Reactome award (NIH: P41 HG003751, ENFIN LSHG-CT-2005-518254, Ontario Research Fund, and EBI Industry Programme).

The data is provided by our numerous collaborators from national and international projects and those available from Publicly available resources.
