Transgenic plant with tissue-selectively reduced cytokinin receptor activity

摘要

The invention relates to a transgenic plant, wherein the activity of AHK2- and/or AHK3- DNA, RNA and/or protein is selectively suppressed or reduced in a specific target tissue of the plant, and wherein the activity of AHK2- and AHK3-DNA, RNA and protein is essentially unaltered in at least one tissue not being target tissue, to methods of making such plants, to methods of making seeds of enhanced size and/or plants with enhanced root branching, and uses of such plants.
