Tissue specific control of the maize (Zea mays L.) embryo, cortical parenchyma, and stele proteomes by RUM1 which regulates seminal and lateral root initiation.

Abstract excerpt

The different root types of maize (Zea mays L.) originate from distinct tissues during development. The maize mutant rum1 (rootless with undetectable meristems 1) does not initiate seminal roots and lateral roots in the primary root. While seminal roots are laid down during embryogenesis, endodermis cells of the parenchyma, and pericycle cells of the stele contribute to the postembryonic initiation of lateral...
