BURP-domain protein genes highly expressed in immature peach fruit

Abstract

Two cDNA clones PF10056 and PF11634 having some homology to BURP-domain protein transcript were found in peach fruit. The deduced amino acid sequences (444 and 427 amino acids, respectively) showed 50% identity to RD22 from Arabidopsis in the C-terminal half. In addition, "CHX₁₀CHX₂₅CHX₂₅CH" (X: arbitrary amino acid) commonly found among BURP-domain proteins was also exist near C-terminal region. In the N-terminal half, sequences of 28 amino acids were repeated 5 times or five and half times. The clones expressed strongly in immature fruit or young leaf although expression was dropped latter half of fruit development. Expression in flower bud was low comparing to young fruit.
