Sucrose Promotes Strawberry Fruit Ripening and Affects

Strawberry is a typical nonclimacteric fruit whose ripening mechanism needs to be further investigated Sucrose has been recently proved as a signal molecule participating in strawberry fruit ripening and related processes While in the effects of sucrose application timing and concentration on ripening fruit qualities remain unclear as well as the transcriptome-wide

Characterization of an AGAMOUS gene expressed throughout

Jul 16 2015In fruits the expansin gene was similarly expressed in both wild type and transgenic samples (Fig 7d) while in the case of sepals the gene transcripts were almost undetectable in wild type ones and showed a ripening-related increment in the transgenic sepals in parallel with the ripening of the fruit (Fig 7c)

Ethylene regulated gene expression in tomato fruit

tomato fruit unable to autonomously produce ripening-related ethylene (data not shown) were therefore used to identify genes responsive to either 15min or 5h ethylene treatment (50mll–1) Isolation of early ethylene-regulated cDNA clones by differential display RNA from ethylene-treated and untreated tomatoes was

Differential expression of genes during banana fruit

Oct 01 2006For most of the genes studied treatment with 1-MCP had almost completely blocked the expression of genes in the fruit indicating that their transcription was ripening related and influenced by ethylene either directly or indirectly (Fig 2A) In order to distinguish between direct and indirect ethylene regulation we treated mature green fruit
