Combined metabolome and transcriptome profiling provides insights into dynamic molecular control of lemon (Citrus Limon L.) peel development.

ABSTRACT:

Background

Lemon peels are crucial quality traits and important sources of nutraceuticals. However, the regulation of peel development remains largely misunderstood. Here, we delved into the dynamic molecular mechanisms that control smooth lemon peel formation through transcriptomics and metabolomics analyses of developing peels at five different stages, including C1 (30 DAF, day after flowering), C2 (60 DAF), C3 (90 DAF), C4 (120 DAF), and C5 (150 DAF).

Results

Our analyses revealed that peel development is stage-specifically regulated, with the transition from stage C2 to stage C3 being the most critical period. Notably, major metabolic adjustments and transcriptional switches occurred between C2 and C3. Particularly, phytohormones and their related genes, flavonoids, terp
