Sequence and developmental expression of a seed storage protein gene in pecan

Summary

A cDNA clone, designated pepl, that encodes a putative seed storage protein in pecan (Carya illinoinensis) was isolated and characterized. Northern blot analysis indicated that this gene is embryo-specific, and is temporally expressed during the reserve accumulation stage of pecan seed development. The nucleotide sequence covers the partial coding region (135 base pairs) with a 3’ non-coding region of 219 base pairs. The deduced amino acid sequence consists of 45 amino acids that bears close identity to seed storage proteins from other plants.
