In Development, Uwe Ohler and his colleague review recent studies that have uncovered significant regulatory functions in developmental transcription for the TFIID basal transcription factors and for the DNA core promoter elements that are located close to transcription start sites.
In Plant Physiology, Philip Benfey and colleagues describe a nondestructive imaging method and analysis system for automated phenotyping and trait ranking of root system architecture that they say is fundamental to identifying important genes in plants like rice.
Synthetic genome-wide associations are not only possible, but inevitable, and under simple but reasonable genetic models, they are likely to account for or contribute to many of the recently identified signals reported in genome-wide association studies, write David Goldstein and Sam Dickson in PLoS Biology.
