Identification of Key Pathways and Candidate Genes Controlling Organ Size Through Transcriptome and Weighted Gene Co-Expression Network Analyses in Navel Orange Plants (<i>Citrus sinensis</i>).

ABSTRACT: Background/Objectives: Organ size is a critical target trait in fruit-tree breeding programs, as it significantly impacts the economic value of plants by influencing their biomass, yield, and quality. Understanding the molecular mechanisms underlying organ size in citrus is essential for breeding new cultivars with superior fruit quality. Methods: In this study, we investigated the regulatory network involved in organ size using the Citrus sinensis 'Newhall' navel orange variety and its large-organ mutant, 'M25'. Results: Ploidy analysis indicated that the organ enlargement observed in 'M25' was not attributable to changes in chromosome ploidy. Furthermore, RNA sequencing of tender leaves and young fruits from both 'M25' and 'Newhall' oranges identified 1817 and
