Abstract
Expansins are plant cell wall loosening proteins involved in the process of fruit softening, loosening cell walls and reducing fruit firmness.
In this study, 35 FvEXPs genes were identified in the F. vesca genome.
These genes were divided into four subfamilies (27 FvEXPAs, 5 FvEXPBs, 1 FvEXLAs, and 2 FvEXLBs) and were distributed unevenly on 7 chromosomes.
Gene structure and motif analysis showed the conserved structure and motif in same subgroup.
However, the different motifs and structures might reveal functional divergence of multi-gene family members of FvEXPs in different developmental stages of fruits.
The expression profiling by RNA-seq and qRT-PCR analysis revealed that the FvEXP genes have distinct expression patterns among different stages of strawberry development and ripening.
Three genes (FvEXPA9, FvEXPA12, and FvEXPA27) were highly expressed in the ripening stage, FvEXPA9 and FvEXPA12 were especially highly expressed in turning stage, whereas FvEXPA27 was highly expressed especially in red stage.
