The characteristics of fruit ripening and expression of ripening-related genes were investigated in epi, an ethylene overproduction mutant of tomato (Lycopersicon esculentum Mill.). The epi produces apparently more ethylene than its wild type VFN8 at every stage of vegetative and fruit growth and ripening; compared to VFN8, the epi fruit showed higher CO2 evolution, faster descending of chlorop...

Recently, long non-coding RNAs (lncRNAs) have been shown to play critical regulatory roles in model plants, such as Arabidopsis, rice, and maize. However, the presence of lncRNAs and how they function in fleshy fruit ripening are still largely unknown because fleshy fruit ripening is not present in the above model plants. Tomato is the model system for fruit ripening studies due to its dramatic...

Sweet cherries are a favourite stone crop among consumers of fruit products. At present, the demand for sweet is growing, which encourages expansion varietal range crops with different ripening periods. The purpose this study was to develop mathematical model predicting formation and cherry pyrene mass depending on weather factors characteristics. conducted during 2008–2019 in conditions Southe...

Our knowledge of the factors mediating ethylene-dependent ripening of climacteric fruit remains limited. The transcription of ethylene-regulated genes is mediated by ethylene response factors (ERFs), but mutants providing information on the specific role of the ERFs in fruit ripening are still lacking, likely due to functional redundancy among this large multigene family of transcription factor...

Tomato (Solanum lycopersicum) is an established model to study fleshy fruit development and ripening. Tomato ripening is regulated independently and cooperatively by ethylene and transcription factors, including nonripening (NOR) and ripening-inhibitor (RIN). Mutations of NOR, RIN, and the ethylene receptor Never-ripe (Nr), which block ethylene perception and inhibit ripening, have proven to be...

The ripening durations and ingredients for the Salchichon sausages were modified to increase pork rear leg consumption by Korean consumers. The salchichon, a ripened pork sausage, was produced to evaluate the efficacy of two different ripening durations with and without rosemary powder on salchichon sausage quality, and the treatments were: i) 45 days of ripening without rosemary, ii) 60 days o...

Modifications to the cell wall of developing and ripening tomato fruit are mediated by cell wall-degrading enzymes, including a beta-d-xylosidase or alpha-l-arabinofuranosidase, which participate in the breakdown of xylans and/or arabinoxylans. The activity of both enzymes was highest during early fruit growth, before decreasing during later development and ripening. Two beta-d-xylosidase cDNAs...

bananas are climacteric fruits and controlling ripening is effective in reducing loss. this experiment studied the effect of packaging (plastic bag, edible wax and plastic bag, plastic bag and 2 or 4 g/kg potassium permanganate) over 5 weeks of cold storage on the quality and characteristics of cavendish cultivar bananas. the samples were removed from storage at 8, 16, 24, 32 and 40 days and fr...

We have studied the transcription of polygalacturonase (PG) and several other riponing-associated genes in wild-type tomato (Lycopersicon esculentum) fruit and three ripening-impaired mutants, rin, nor, and Nr. In wild-type fruit, the PG gene becomes transcriptionally active early in ripening and remains transcriptionally active during the ripening process. Fruit of the three ripening-impaired ...

Protein synthesis by intact Bartlett pear fruits was studied with ripening as measured by flesh softening, chlorophyll degradation, respiration, ethylene synthesis, and malic enzyme activity. Protein synthesis is required for normal ripening, and the proteins synthesized early in the ripening process are, in fact, enzymes required for ripening. (14)C-Phenylalanine is differentially incorporated...
