Abstract:

Twelve Fasciclin-like arabinogalactan proteins(FLA)sequences were screened from the peach(Prunus persica)genome database. Protein structure analysis of the 12 FLAs revealed that PpFLA7 seems not the classical member of FLA family due to the absence of glycosylated sites. PpFLA6 showed a significant difference with other ones because of a distinctive composition and distribution of conserved domains. Phylogenetic analysis indicated that PpFLAs family could be classified into 3 groups:Clade Ⅰ,Clade Ⅱ,and Clade Ⅲ. Expression analysis by qPCR manifest that 12 PpFLAs were differentially expressed in various tissues,and the highest expression of PpFLA4 in firm-ripe peach fruit suggest that this member may play an important role in peach fruit during ripening.
