“…This gene is suggested to play a major role in fruit pigmentation of the KNY2 inbred during the ripening stages. In a previous study, we detected and confirmed a SNP at the -77 position of the CYC -B gene that showed perfect association and a dominant phenotype in KNY2 for orange fruit color [16] (Fig. 2b, d).…”

“…S2). To examine the genotypic variation in the F2 generations, SNP sites of SGR and CYC-B genes were identified [16, 30]. The SGR gene plays an important role in the regulation of chlorophyll degradation in tomato fruits and leaves [31, 32].…”

“…Three isoforms of the PSY gene have been identified in tomato. The PSY1 isoform is responsible for fruit ripening, whereas PSY2 and PSY3 are likely predominant in green tissues and roots, respectively [14–16]. PSY1 and PDS genes are upregulated during fruit ripening, while genes for enzymes carrying out cyclisation of lycopene such as β-Lcy and ε-Lcy are downregulated, resulting in low levels of β-carotene during tomato ripening [17].…”

Our previous report had showed the evidence of CYC-B ( β-lycopene cyclase ) gene expression associated with orange color of fleshy fruit in tomato [16].

BackgroundTomatoes provide a significant dietary source of the carotenoids, lycopene and β-carotene. During ripening, carotenoid accumulation determines the fruit colors while chlorophyll degradation. These traits have been, and continue to be, a significant focus for plant breeding efforts. Previous work has found strong evidence for a relationship between CYC-B gene expression and the orange color of fleshy fruit. Other work has identified a point mutation in SGR that impedes chlorophyll degradation and causes brown flesh color to be retained in some tomato varieties.MethodsWe crossed two inbred lines, KNY2 (orange) and KNB1 (brown) and evaluated the relationship between these genes for their effect on fruit color. Phenotypes of F2 generation plants were analyzed and a novel ‘orange-brown’ fruit color was identified.ResultsWe confirm two SNPs, one in CYC-B and another in SGR gene sequence, associated with segregation of ‘orange-brown’ fruit color in F2 generation. The carotenoid and chlorophyll content of a fleshy fruit was assessed across the different phenotypes and showed a strong correlation with expression pattern of carotenoid biosynthesis genes and SGR function. The orange-brown fruit has high β-carotene and chlorophyll. Our results provide valuable information for breeders to develop tomato fruit of a novel color using molecular markers.Electronic supplementary materialThe online version of this article (doi:10.1186/s41065-016-0023-z) contains supplementary material, which is available to authorized users.

A yellow green peel mutant (ygp) in cucumber was caused by a mutation in Csa2G352940 encoding MYB36 transcription factor. Peel color is one of the important agronomic traits of cucumber (Cucumis sativus L.). However, studies on the molecular regulation mechanism of peel color in cucumber are few. In this study, a cucumber yellow green peel mutant (ygp) of cucumber mutagenized with ethylmethylsulfone by using a wild type cucumber with dark green peel was identified. Pigment measurements indicated that the chlorophyll content of the ygp mutant was less than that of the wild type. Genetic analysis revealed that the phenotype of the ygp mutant was monogenic recessive inheritance. MutMap and genotyping results demonstrated that Csa2G352940 (CsMYB36), encoding the transcription factor MYB36, was the causal gene of the ygp mutant in cucumber. CsMYB36 was downregulated in the fruit of the ygp mutant. Transcriptome profile analysis of the fruit peel of the ygp mutant identified 92 candidate genes including genes that encode Casparian strip (CsCASP1) and pigment synthesis protein (CsMYC2) involved in peel color development in cucumber. CsMYB36 may regulate yellow green coloration in cucumber by interacting with these genes. Overall, these results showed that CsMYB36 can regulate the yellow green peel coloration in cucumber.
