Biochemical and molecular analysis of pink tomatoes: deregulated expression of the gene encoding transcription factor SlMYB12 leads to pink tomato fruit color.
The color of tomato fruit is mainly determined by carotenoids and flavonoids. Phenotypic analysis of an introgression line (IL) population derived from a cross between Solanum lycopersicum 'Moneyberg' and the wild species Solanum chmielewskii revealed three ILs with a pink fruit color. These lines had a homozygous S. chmielewskii introgression on the short arm of chromosome 1, consistent with t...
متن کاملFruit-Surface Flavonoid Accumulation in Tomato Is Controlled by a SlMYB12-Regulated Transcriptional Network
The cuticle covering plants' aerial surfaces is a unique structure that plays a key role in organ development and protection against diverse stress conditions. A detailed analysis of the tomato colorless-peel y mutant was carried out in the framework of studying the outer surface of reproductive organs. The y mutant peel lacks the yellow flavonoid pigment naringenin chalcone, which has been sug...
متن کاملMolecular Insights Reveal Psy1, SGR, and SlMYB12 Genes are Associated with Diverse Fruit Color Pigments in Tomato (Solanum lycopersicum L.).
The color of tomato (Solanum lycopersicum) fruit flesh is often used as an indicator of quality. Generally, fruit color is determined by the accumulation of carotenoids and flavonoids, along with concomitant degradation of chlorophylls during ripening. Several genes, such as phytoenesynthetase1 (Psy1), STAY-GREEN (SGR), and SlMYB12, have been extensively studied to elucidate the genes controlli...
متن کاملIdentification of Linked Markers for Delayed Fruit Ripening in Tomato Using Simple Sequence Repeat (SSR) Markers
Tomato (Solanum lycopersicum L.) is an important vegetable crop and acts as model plant for fruit development studies. Besides that, post-harvest damage is a devastating phenomenon often associated with ripening process in tomato which in turn leads to greater yield loss. Understanding the genetics, molecular and biochemical pathways is the key to overcome the existing situation. In th...
متن کاملNull Allele Frequencies at HLA-G Locus in Iranian Healthy Subjects
Background: HLA-G gene contains 15 alleles including a null allele, HLA-G*0105N. Previous studies have shown that HLA-G*0105N does not encode the complete HLA-G1 or HLA-G5 isoforms but encodes a functional HLA-G protein with the ability to in-hibit NK cell cytolysis. Thus, although the biological functions of HLA-G1 and HLA-G5 proteins are abrogated, other isoforms such as HLA-G2 can replace th...
