Changes in ripening-related processes in tomato conditioned by the alc mutant

Theoretical and Applied Genetics, 1988
The alc mutation affects the ripening and storability of tomato fruit. The alteration of fruit color in alc lines is due to a reduction in total pigment and a reduction in lycopene relative to total carotinoids. Polygalacturonase (PG) activity is reduced to less than 5% of normal, and the isozymes PG2a and PG2b are absent in alc fruit.

cDNA cloning and characterisation of novel ripening-related mRNAs with altered patterns of accumulation in the ripening inhibitor (rin) tomato ripening mutant

Plant Molecular Biology, 1993
A cDNA library produced from mRNA isolated from the pericarp of wild-type tomato fruit (Lycopersicon esculentum Mill. cv Ailsa Craig) at the first visible sign of fruit ripening was differentially screened to identify clones whose homologous mRNAs were present at reduced levels in fruit of the tomato ripening mutant, ripening inhibitor,rin. Five clones

Altered sensitivity to ethylene in ‘Tardivo’, a late‐ripening mutant of Clementine mandarin

Physiologia Plantarum, 2013
‘Tardivo’ mandarin is a mutant of ‘Comune’ Clementine with a delay in peel degreening and coloration, allowing late harvesting. In this work, we have explored if the late‐harvesting phenotype of ‘Tardivo’ mandarin is related to altered perception and sensitivity to ethylene.

Mode of inheritance of Alcobaca, a tomato fruit-ripening mutant

Euphytica, 1981
Alcobaca, an abnormally ripening tomato mutant, was crossed with the normal cultivar Rutgers. Examination of F1, F2 and BC1 populations indicated that a single recessive gene controls the mutant phenotype. No maternal effect was detected.

Changes in Polygalacturonase Isoenzymes during the ‘Ripening’ of Normal and Mutant Tomato Fruit

European Journal of Biochemistry, 1980
Polygalacturonase activity is not detectable in mature green tomato fruits but appears as fruits begin to change colour and continues to increase during the ripening period. There is a sequential appearance of two isoenzymes, polygalacturonase 1 and 2, during ripening.

Survival of Brucella abortus aqp X Mutant in Fresh and Ripened Cheeses

Foodborne Pathogens and Disease, 2015
The objective of this work was to evaluate the survival of a Brucella abortus aqpX mutant during the elaboration and conservation of fresh and ripened cheeses at 4 °C and 24 °C. The pH values and water activity were monitored for each type of cheese. The fresh cheese was elaborated with raw milk inoculated with 6×10⁸ colony-forming units (CFU)/mL each ...

Polyuronide solubilization during ripening of normal and mutant tomato fruit

Phytochemistry, 1987
Abstract The amount and molecular size of soluble polyuronide extractable from ripening tomatoes is markedly affected by residual enzyme activity. The efficacy of phenol-acetic acid-water treatment to remove this residual activity is demonstrated. Data obtained using treated wall preparations confirms that there is an increase in soluble polyuronide ...

Ripening and cell wall synthesis in normal and mutant tomato fruit

Phytochemistry, 1991
Abstract Cell wall synthesis during development of ‘Rutgers’, rin and nor tomatoes was quantified at different ‘ripening’ stages by measuring incorporation of 14 C into pericarp cell walls 18 hr after pedicel injection of [U- 14 C]sucrose. Colour (Hunter ‘a’ and ‘b’ values) and pericarp firmness were also monitored.

ACS4 exerts a pivotal role in ethylene biosynthesis during the ripening of tomato fruits in comparison to ACS2.

The Plant Journal
In the climacteric fruit tomato (Solanum lycopersicum), 1-aminocyclopropane-1-carboxylic acid (ACC) synthase 2 (ACS2) and ACS4 are jointly recognized as key enzymes in orchestrating System-2 ethylene biosynthesis during fruit ripening.

Salt-stress Induces Partial Ripening of the nor Tomato Mutant but Expression of only some Ripening-Related Genes

Journal of Plant Physiology, 1991
Summary Tomato plants homozygous for the character non-ripening (nor) when grown in normal nutritional conditions produce fruit that change colour at maturity only very slowly, in a typical non-climacteric fruit behaviour pattern. However, by subjecting the plants to salinity stress, at the end of development the fruit redden and partially ripen ...
