Towards decoding the conifer giga-genome. by Mackay, J, Dean, J, Plomion, C, Peterson, D, Cánovas, F, Pavy, N, Ingvarsson, P, Savolainen, O, Guevara, M, Fluch, S, Vinceti, B, Abarca, D, Díaz-Sala, C, Cervera, M

“…Several new initiatives have been launched recently to sequence conifer genomes including pines, spruces and Douglas-fir. Owing to the very large genome sizes ranging from 18 to 35 gigabases, sequencing even a single conifer genome had been considered unattainable until the recent throughput increases and cost reductions afforded by next generation sequencers. …”

Pseudomonas fluorescens BBc6R8 type III secretion mutants no longer promote ectomycorrhizal symbiosis. by Cusano, A, Burlinson, P, Deveau, A, Vion, P, Uroz, S, Preston, G, Frey-Klett, P

“…The Mycorrhiza Helper Bacterium (MHB) Pseudomonas fluorescens BBc6R8 promotes the ectomycorrhizal symbiosis between Douglas fir roots and Laccaria bicolor. In this study, we identified a non-flagellar type III secretion system (T3SS) in the draft genome of BBc6R8 similar to that described in the biocontrol strain P. fluorescens SBW25. …”
