Malate accumulation and transcriptome patterns during fruit development in sweet Cherry (Prunus avium L.).

ABSTRACT:

Background

Fruit acidity serves as a primary determinant of organoleptic quality in fleshy fruits. Malate predominates and significantly contributes to the fruit flavor profile and palatability in sweet cherry. However, the molecular mechanisms regulating malate accumulation in fruit cells of this species remain poorly understood.

Results

In this study, we performed quantitative profiling of titratable acidity (TA) in 97 sweet cherry cultivars at maturity, establishing a phenotyping framework for acidity classification. Temporal metabolomic analyses identified malate as the dominant organic acid throughout fruit development, exhibiting a biphasic accumulation pattern. Integrated transcriptomic profiling of high-acid and low-acid fruits across developmental stages revealed 3,
