Alternative splicing occurs in auxin-mediated trade-off between fruit development and quality in tomato.

ABSTRACT:

Background

This study assessed the effects of auxin analog, para-chlorophenoxyacetic acid (pCPA), on fruit set and development in Micro-Tom tomato (TOMJPF00001) via phenotypic, biochemical, metabolomic, and transcriptomic analyses.

Results

pCPA treatment significantly (p < 0.05) reduced floral abscission, increased fruit set and yield, while impacting fruit morphology, ripening, sugar content, organoleptic properties, and phytohormone profiles. Metabolomic profiling revealed 836 differentially accumulated metabolites (DAMs). Among these, several phenylpropanoid-related DAMs (isoferulic acid, 6-methylcoumarin, naringenin, hesperetin 5-O-glucoside, quercetin, and dihydrokawain) were upregulated in immature green, mature green, and breaker fruits, but downregulated in red ripe
