Abstract excerpt
The pedicel of the maize (Zea mays L.) caryopsis is a complex structure consisting of layers of specialized cell-types involved with solute transfer into the developing kernel. A molecular marker for one of these cell layers, the phloem parenchyma, has been obtained by differential screening of a cDNA library from 7 days after pollination (DAP) kernels. The clone encodes a novel processed type of thioredoxin,...
