The tomato (Solanum lycopersicum) protein MADS-RIN plays important roles in fruit ripening. In this study, the functions of two homologous tomato proteins, FUL1 and FUL2, which contain conserved MIKC domains that typify plant MADS-box proteins, and which interact with MADS-RIN, were analysed. Transgenic functional analysis showed that FUL1 and FUL2 function redundantly in fruit ripening regulat...

The ripening of bananas is seen by a characteristic change of their color from deep green to bright yellow. Likewise, their over-ripening and eventual rotting are accompanied by the appearance of an unappetizing brown. Chlorophyll breakdown is a major contributor to the visual signs of these processes in bananas. Outlined here are the basic structures of chlorophyll catabolites in higher plants...

Background and Objectives: This study is the first research on the physiochemical characteristics, microbial population and microstructure of Poosti cheese over 90-days of ripening. The main difference between Poosti cheese and other types of traditional cheese is the skin, which is used for its storage. Materials and Methods: Physicochemical characteristics including moisture, salt, pH, acidi...

An increase in the enzyme activity of 1-aminocyclopropane-1-carboxylic acid (ACC) synthase and ACC oxidase induces the evolution of ethylene during the ripening of passion fruit. A much higher level of ethylene is produced in arils than in seeds or peels during ripening. The pattern of expression of two ACC synthase genes (PE-ACS1 and PE-ACS2), one ACC oxidase gene (PE-ACO1), and two ethylene r...

BACKGROUND Ripening of fleshy fruit is a complex developmental process involving the differentiation of tissues with separate functions. During grapevine berry ripening important processes contributing to table and wine grape quality take place, some of them flesh- or skin-specific. In this study, transcriptional profiles throughout flesh and skin ripening were followed during two different sea...

Changes in the concentrations of the free fatty acids (FFA) containing an even number of carbon atoms in Serra cheese were monitored using a two-way factorial design over a ripening period of 35 days throughout the cheesemaking season. Both time variables had statistically significant effects at the 5% level on the concentrations of FFA. The concentration of stearic acid increased signt$cantly ...

Transcriptional studies in relation to fruit ripening generally aim to identify the transcriptional states associated with physiological ripening stages and the transcriptional changes between stages within the ripening programme. In non-climacteric fruits such as grape, all ripening-related genes involved in this programme have not been identified, mainly due to the lack of mutants for compara...

Fruit ripening is a developmental process that is exclusive to plants whereby mature seed-bearing organs undergo physiological and metabolic changes that promote seed dispersal. Molecular investigations into ripening control mechanisms have been aided by the recent cloning of tomato ripening genes that were previously known only through mutation. Advances in the genomics of tomato have provided...

Tomato (Solanum lycopersicum) fruit ripening-specific N-glycan processing enzyme, β-D-N-acetylhexosaminidase (β-Hex), plays an important role in the ripening-associated fruit-softening process. However, the regulation of fruit ripening-specific expression of β-Hex is not well understood. We have identified and functionally characterized the fruit ripening-specific promoter of β-Hex and provided...
