Auxin-binding Sites of Maize Coleoptiles Are Localized on Membranes of the Endoplasmic Reticulum.

abstract：:The effect of seed coat removal on the synthesis of alpha-amylase isoenzymes in wheat was investigated. The immature wheat endosperm-aleurone (seed coat and embryo detached) produced considerably less alpha-amylase activity than immature whole or de-embryonated wheat kernels, when incubated under identical conditions ...

abstract：:Apical dominance is the process whereby the shoot tip inhibits the growth of axillary buds along the stem. It has been proposed that the shoot tip, which is the predominant source of the plant hormone auxin, prevents bud outgrowth by suppressing auxin canalization and export from axillary buds into the main stem. In t...
