Interpretive Summary:

Technical Abstract: Functional genomics is an emerging technological frontier in postharvest crop management. This is driven in part by exponential growth of genomics resources for specialty crops, which include genomes and transcriptomes. These global¬ scale technologies are allowing insights into responses of Rosaceous tree fruit to modified atmospheres, various storage temperature regimes, and crop protectants in the postharvest period. These insights will allow researchers and producers to maximize favorable outcomes, especially with regard to differential at-harvest fruit status that can influence postharvest outcomes. Previous work on the samples we sequenced showed, as a function of on-tree fruit position, that pear fruit had distinct fruit quality attributes and metabolite profiles at harvest and throughout the storage period. To discover the gene activities associated with these differences, we sequenced the transcriptome of these D'Anjou pear fruit samples. A primary hurdle to analyzing european pear transcriptome data is the utility of the reference Bartlett genome; we therefore also discuss this important prerequisite and how it impacts RNA-Seq analysis.
