Constitutive expression of EIL-like transcription factor partially restores ripening in the ethylene-insensitive Nr tomato mutant.
Climacteric fruit ripening is regulated by the phytohormone ethylene. ETHYLENE-INSENSITIVE3 (EIN3) is a transcription factor that functions downstream from the ethylene receptors in the Arabidopsis ethylene signal transduction pathway. Three homologues of the Arabidopsis EIN3 gene have been identified in tomato, Lycopersicon esculentum, EIN3-like or LeEIL, LeEIL1, LeEIL2, and LeEIL3. These tran...
متن کاملFruit Ripening Regulation of α-Mannosidase Expression by the MADS Box Transcription Factor RIPENING INHIBITOR and Ethylene
α-Mannosidase (α-Man), a fruit ripening-specific N-glycan processing enzyme, is involved in ripening-associated fruit softening process. However, the regulation of fruit-ripening specific expression of α-Man is not well understood. We have identified and functionally characterized the promoter of tomato (Solanum lycopersicum) α-Man to provide molecular insights into its transcriptional regulati...

Introduction The role of ethylene in regulating the expression of Tomato fruit ripening involves complex gene expression three lipoxygenase (LOX) genes TomloxA, TomloxB and and biochemical changes which ultimately result in alteraTomloxC during fruit ripening has been investigated. tions to the physical properties of the fruit giving rise to The study used a combination of low-ethylene fruit ch...
متن کاملRegulation of carotenoid formation during tomato fruit ripening and development.
Carotenoid biosynthesis and its regulation during tomato fruit development and ripening is a complex process that occurs alongside the differentiation of chloroplasts into chromoplasts and changes to the organoleptic properties of the fruit. Unusually for plants, the ripe tomato fruit accumulates large amounts of lycopene, as the pattern of gene expression found in green fruit changes during fr...
متن کاملExpression and DNA binding activity of the tomato transcription factor RIN (ripening inhibitor).
Recently, we have found that the accumulation of ripening inhibitor (RIN) protein increased gradually during tomato fruit ripening. Here, the recombinant protein was expressed in Escherichia coli and affinity-purified. The DNA binding activity of renatured RIN protein was tested by electrophoretic mobility shift assay. The results indicated that an optimal expression and purification system was...
