Other claims from this paper (12)
- Observation The high-acid landrace showed very rapid malate accumulation and relatively fast degradation.
- Observation The low-acid landrace showed minor changes in malate levels during fruit development.
- Observation DEGs from three clusters were significantly enriched in the pyruvate metabolism pathway during Chinese cherry fruit development.
- Observation DEGs from three clusters were significantly enriched in the TCA cycle pathway during Chinese cherry fruit development.
- Association Malate biosynthesis genes cMDH and PEPC2 were up-regulated in the high-acid landrace.
- Association Malate transport genes ALMT4 and VHP were up-regulated in the high-acid landrace.
- Association NADP-ME, a gene associated with malate degradation, was down-regulated in Chinese cherry.
- Association Key structural genes and transcription factors (MYB, ARF, AP2, bHLH) showed strong co-expression correlations in Chinese cherry.
- Mechanism CpODORANT1like is a potential regulator of acidity in Chinese cherry, modulating NADP-ME expression.
- Mechanism CpARF2Blike is a potential regulator of acidity in Chinese cherry, modulating PEPC2 expression.
- Observation The candidate genes were validated in 34 Chinese cherry genotypes by integrated phenotypic and expression analysis.
- Mechanism Malate accumulation in Chinese cherry is regulated at both the metabolic and the vacuolar storage levels.
