Xue Zhang and colleagues report mutations in an inhibitory upstream open reading frame flanking the human hairless gene in individuals with Marie Unna hereditary hypotrichosis. These mutations result in increased translation of the main physiological hairless ORF, suggesting that fine-tuning of hairless protein levels is important in the control of hair growth.
Timothy Nelson and colleagues present a transcriptome atlas of 40 key cell types from rice (Oryza sativa). The atlas reveals previously unrecognized cellular properties, and should serve as an essential resource for functional genomic analyses of rice and other plants.
