Genomic Approaches - Innovative Tools to Improve Quality of Fresh Cut Produce

Innovative and Integrated Approaches to Investigating Postharvest Stress Physiology and the Biological Basis of Fruit Quality During Storage

“…The same approach has been used to investigate the molecular mechanism underlying tolerance to CI in peach (Granell et al, 2007). For this goal, a cDNA microarray, named CHILLPEACHt, has been developed selecting targets from a database (ChillpeachDB) containing 8,144 cDNA sequences obtained from the mesocarp of sensitive and tolerant peaches.…”

Challenges in Feasible Problem Construction in Nutritional Genomics: An Empirical Study

“…The employment of state-of-the art techniques is particularly useful in defining processes that affect fruit quality. Genomic technologies are currently being used in a range of crops coupled with other technologies such as genetic marker development and breeding lines in order to improve the quality of fruits and vegetables (Granell et al 2007). Emerging genomic tools and approaches are rapidly providing new clues and candidate genes that are expanding the known regulatory circuitry of ripening (Adams-Phillips et al 2004).…”

“…Currently, a combination of transcriptomic, proteomic, and metabolomic approaches has been applied in order to identify gene regions/QTLs relevant to tomato fruit quality (reviewed in Granell et al 2007). Positional cloning of genes defined by ripening defect mutations in tomato fruit system have led to the identification of novel ethylene signal transduction components, as well as to the elucidation of the function of unique transcription factors, affecting ripening-related ethylene production (reviewed in Barry and Giovannoni 2007).…”

“…The major commercial traits in citrus include improved fruit quality, higher yield, and tolerance to environmental stresses (Terol et al 2007 performance, the existence of differential preformed mechanisms as well as inducible responses to cold temperature storage has been revealed with the employment of microarray analysis. These tools and analysis provide valuable information to design postharvest protocols and to introduce those candidate genes in the plant breeding programs (Granell et al 2007). …”

“…In-house citrus microarrays have been developed to identify candidate for fruit quality genes and to study the impact of genetic background and environment on gene expression (reviewed in Granell et al 2007). A Citrus GeneChip microarray, developed by using the Affymetrix technology, was employed to gain insight into the molecular mechanisms involved in the responses of citrus fruit to low-temperature storage (Maul et al 2008).…”
