Zhang et al. describe conserved and unique features of the homeologous maize Aux/IAA proteins RUM1 and RUL1. Although being structurally almost identical and harboring very similar biochemical properties the two proteins are at least in part interwoven into different molecular networks.

Tai et al. highlight root type-specific functional diversity in maize. Embryonic seminal roots display unique anatomical features and a distinct gene expression profile compared to primary and crown roots.

Opitz et al. provide insight into tissue-specific transcriptomic plasticity in maize primary roots upon water deficit. RNA-seq analyses reveal that most genes regulated by water scarcity are specific for a certain root tissue.
