Abstract

This article focuses on the genetic and molecular mechanisms underlying the green ripe fruit phenotype in the cultivated tomato cultivar 'Lvbaoshi' (LBS). The study identifies three key genes—SlMYB12, STAY-GREEN 1 (SlSGR1), and PHYTOENE SYNTHASE 1 (SlPSY1)—whose mutations collectively cause LBS fruits to develop green ripe fruits with colorless peel. Specifically, a 603 bp deletion in the SlMYB12 promoter leads to colorless peel, while mutations in SlSGR1 and SlPSY1 disrupt chlorophyll degradation and carotenoid biosynthesis, respectively, resulting in green flesh. Functional analyses, including RNA interference and CRISPR/Cas9 gene editing, confirm that these genes and their interactions regulate fruit color in both cultivated and some wild tomato species, with implications for tomato breeding and fruit quality improvement.
