  1. aHomologous search was conducted by BLASTP against the Arabidopsis Refseq database (http://www.arabidopsis.org/index.jsp). E-value was set to <1E-10. The Arabidopsis gene ID with highest score is picked for further analysis
  2. bThe proteins were annotated based on the public databases: Arabidopsis database (http://www.arabidopsis.org/index.jsp) and cucumber Refseq database (http://cucumber.genomics.org.cn/page/cucumber/index.jsp)
  3. cThe proposed biological processes were refer from the GO terms and related research reports of the top hit Arabidopsis genes
  4. dThe expression fold was calculated as the ratio of the protein expression in 2 dpa fruits vs. protein expression in 0 dpa fruit, P-value <0.05; The dramatically increased (fold >5) DEPs were marked with stars
