An international team of researchers published their work on Oryza glaberrima (African rice) genome sequence in the journal Nature Genetics (http://www.nature.com/doifinder/10.1038/ng.3044). The work includes genomics analyses of 20 O. glaberrima and 94 O. barthii accessions, which supported the growing hypothesis that O. glaberrima was domesticated in the Niger river region of Africa. The 33,164 protein coding and 701 tRNA genes were identified in the 314 Mb draft genome of O. glaberrima.

Plant Reactome now provides projections for eighteen plant species (nine monocots and nine dicots).
Using curated rice pathways as a reference, Plant Reactome predicts pathways in other plant species on the basis of Compara orthology projections.

International Rice Research Institute (IRRI), Chinese Agricultural Academy of Sciences (CAAS) and Beijing Genomics Institute (BGI) have come together to sequence the genomes of 3000 rice accessions. A report of this unprecedented sequencing effort and access to the sequence information was recently published in the Journal GigaScience (Jia-Yang Li, Jun Wang, and Robert S Zeigler GigaScience May 2014, 3:8).

Strigolactones are a class of carotenoid derived compounds. As the most recently described class of plant hormones they are reported to play an ever expanding role in plant development. As a plant hormone, they act like signaling molecules which communicate with other plant hormone systems including auxins, cytokininins and ABA. Equally significant is their role in promoting symbiotic relationships between plants and soil microbes, a key aspect of plant’s mineral nutrition. Interestingly, name “Strigolactone” is derived from this latter role.

Please be advised that there will be a network upgrade affecting Gramene servers (internet and FTP) on Sunday, June 8th beginning at 11:00PM EDT and concluding at 1:00AM EDT Monday, June 9th.
Plan accordingly so that your work with the Gramene website and services is not affected by the temporary (~2h) internet outage.

We recently undertook an effort to project our manually curated Plant Reactome Oryza sativa (rice) pathway data onto Zea mays (maize) and Arabidopsis thaliana, and we were curious to compare gene-level projection results derived using both Compara and Inparanoid methodologies.

For the first time in the context of the Maize Genetics Conference (Beijing, China on March 13-16, 2014), Gramene seized the opportunity to present a workshop for the maize community. The meeting brought about 600 maize researchers from around the World. Among those, about 100 meeting participants from Asia, Europe, and North America attended the Gramene workshop. The workshop provided an overview of Gramene’s comparative genomics and variation resources, including the Ensembl genome browser, BLAST and BioMart.
