The aim of this work was to investigate the occurrence of phosphoenolpyruvate carboxykinase (PEPCK) in different tissues of Arabidopsis thaliana throughout its vegetative and reproductive growth. The A. thaliana genome contains two PEPCK genes (PCK1 and PCK2), and these are predicted to generate 73,404 and 72,891 Da protein products, respectively. Both genes were transcribed in a range of tissu...

Idesia polycarpa, is a valuable oilseed-producing tree of the Flacourtiaceae family that has the potential to fulfill edible oil production and is also a possible biofuel feedstock. The fruit is unique in that it contains both saturated and unsaturated lipids present in pericarp and seed, respectively. However, triglyceride synthesis and storage in tissues outside of the seeds has been poorly s...

Sorbitol, the primary photosynthate and translocated carbohydrate in apple (Malusxdomestica Borkh.), is converted to fructose by sorbitol dehydrogenase (SDH; EC 1.1.1.14) which is active in apple fruit throughout development. In the apple genome, nine SDH genes have been isolated and their sequences characterized, but their individual expression patterns during apple fruit set and development h...

Soluble sugar accumulation pattern and contents were studied in two Iranian melon cultivars, ‘Suski Sabz’ and ‘Jalali Zard’ (Cucumis melo L. Inodorous). Sucrose, glucose and fructose contents were determined in different mesocarp tissues of developing fruits during days after pollination (DAP). They were characterised by enhanced accumulation of glucose and fructose during early fruit developme...

Physiological processes characteristic of ripening in tissues of intact tomato fruit (Lycopersicon esculentum Mill.) were examined in excised pericarp discs. Pericarp discs were prepared from mature-green tomato fruit and stored in 24-well culture plates, in which individual discs could be monitored for color change, ethylene biosynthesis, and respiration, and selected for cell wall analysis. W...

Fruit physiology is strongly affected by both fruit temperature and water losses through transpiration. Fruit temperature and its transpiration vary with environmental factors and fruit characteristics. In line with previous studies, measurements of physical and thermal fruit properties were found to significantly vary between fruit tissues and maturity stages. To study the impact of these vari...

MdMYB10 gene expression results in accumulation of anthocyanin in many tissues including flesh of applefruit. The MdMYB1 and MdMYBA genes are close homologues to MdMYB10 gene and both are responsiblefor red color phenotype in apple fruit skin. In the current study, an apple genome sequence draft analysisindicated that these three genes are located in a unique contig. Further a...

‘Pink Lady’ apple fruit were evaluated for anti-oxidative stress at various stages of fruit maturity and ripening. Fruit were harvested at weekly intervals starting 7 days before anticipated commercial harvest up to 42 days after commercial harvest (DACH), and then fruit harvested at commercial maturity were allowed to ripen at 22 ± 0.5C for 20 days. Ethylene production and respiration rate inc...

Well-known epigenetic DNA modifications in mammals include the addition of a methyl group and a hydroxyl group to cytosine, resulting in 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) respectively. In contrast, the abundance and the functional implications of these modifications in invertebrate model organisms such as the honey bee (Apis mellifera) and the fruit fly (Drosophila melan...
