Abstract

A Zea mays cDNA clone, ZmERabp4, coding for a new member of the auxin-binding
protein family was isolated. The primary amino acid sequence contains an N-
terminal hydrophobic leader sequence, a potential glycosylation site (Asn136-Thr-
Thr) and a C-terminal KDEL motif known to be responsible for retention of
proteins within the lumen of the ER. The expression pattern of the ZmERabp4 gene
in various organs of maize differs from the expression pattern previously
observed for the ZmERabp1 gene. The ZmERabp4 gene is expressed highly in male
flower organs, whereas the ZmERabp1 gene shows highest expression in female
flower parts. In situ hybridization and analysis by laser scanning microscopy
revealed enhanced levels of expression for both genes in the coleoptile when
compared with the primary leaf of etiolated maize seedlings.
