Inhibition of leaf process by p-fluorophenylalanine during induction of flowering in the cocklebur.

abstract：:Here, we present a genome-wide overview of transcriptional circuits in the agriculturally significant crop species maize (Zea mays). We examined transcript abundance data at 50 developmental stages, from embryogenesis to senescence, for 34,876 gene models and classified genes into 24 robust coexpression modules. Modul...
