This week’s Research in Focus is reprinted from an In Brief published by Science Editor Nancy Hofmann in The Plant Cell, which summarizes an article newly published by Gerttula et al. This study examines the formation of tension wood, a specialized tissue that forms on the upper side of a fallen woody angiosperm stem that … Read more
This week we feature an article that will be interesting to different people for different reasons. The main thrust is to uncover the genetic basis for the black rice trait, which the authors trace through an elegant and comprehensive analysis and by sidestepping a few red herrings. For those who are engaged by the broader … Read more
Scientists have long dreamed of the ability to make targeted genomic changes: precise and specific alterations in an organism’s DNA to affect its phenotype. Recently, this dream has become a reality through the discovery and engineering of nucleases that can be targeted to precise genomic locations. Double-strand breaks produced by targeted nucleases can induce mutations … Read more
Karrikins are small molecules found in smoke that promote seed germination and have been associated with the activation of seeds following fire (Nelson et al., 2012). Strigolactones are structurally similar small molecules that act as endogenous hormones and as secreted signals that promote the germination of parasitic plants and branching responses in mycrorrhizal fungi (Brewer … Read more
