Expansins are plant proteins that have the capacity to induce extension in isolated cell walls and are thought to mediate pH-dependent cell expansion. J.K.C. Rose, H.H. Lee, and A.B. Bennett ([1997] Proc Natl Acad Sci USA 94: 5955-5960) reported the identification of an expansin gene (LeExp1) that is specifically expressed in ripening tomato (Lycopersicon esculentum) fruit where cell wall disas...

Growing population, together with unpredictable climatic changes and dwindling fertile land, has forced to explore the alternate underutilized flora from the rich biome. There is a great opportunity for economic growth in agriculture system by introducing underutilized commodity in market place. Therefore, the present study was undertaken to elucidate the nutritional potential of an important u...

Ripening is one of the key processes associated with the development of major organoleptic characteristics of the fruit. This process has been extensively characterized in climacteric fruit, in contrast with non-climacteric fruit such as grape, where the process is less understood. With the aim of studying changes in gene expression during ripening of non-climacteric fruit, an Illumina based RN...

The main aim of the present study was the evaluation of proteins and antioxidant potential in ethylene-treated kiwifruit during the first 10 days of ripening. Kiwifruit samples were randomly divided into two groups: treated and untreated. Flesh firmness, sensory value, visual score, free sugars, soluble solids, ethylene biosynthesis, proteins, dietary fibers, total polyphenols and antioxidant p...

Besides an essential source of energy, light provides environmental information to plants. Photosensory pathways are thought to have occurred early in plant evolution, probably at the time of the Archaeplastida ancestor, or perhaps even earlier. Manipulation of individual components of light perception and signaling networks in tomato (Solanum lycopersicum) affects the metabolism of ripening fr...

The production of tomato under low-temperature stress in the open fields is a challenge faced by many farmers. current study compares use different ethylene treatments to accelerate fruit ripening during two successive seasons cold stress. included foliar application ethrel (2500, 5000, and 7500 ppm) field at mature green stage, dipping collected fruits solution (1000, 1500, 2000 right after ha...

The disappearance of chlorophyll is a visual sign of fruit ripening. Yet, chlorophyll breakdown in fruit has hardly been explored; its non-green degradation products are largely unknown. Here we report the analysis and structure elucidation of colorless tetrapyrrolic chlorophyll breakdown products in commercially available, ripening bananas (Musa acuminata, Cavendish cultivar). In banana peels,...

Strawberry fruit contain the allergenic Fra a proteins, members of the pathogenesis-related 10 protein family that causes oral allergic syndrome symptoms. Fra a proteins are involved in the flavonoid biosynthesis pathway, which might be important for color development in fruits. Auxin is an important plant hormone in strawberry fruit that controls fruit fleshiness and ripening. In this study, w...

Pear fruit usually soften and develop a melting texture when harvested at the mature green stage and ripened. The reason why the fruit does not fully ripen on the tree is unknown. To clarify this, our attention was directed to the continuous supply of assimilates and/or other substances into the fruit via phloem transport. To determine the effect of inhibiting phloem transport on fruit ripening...

Mango fruit (Mangifera indica L.), cv. ‘Cogshall’, ‘Kent’ and ‘Keitt’ were harvested at different maturities (61–115 d past flowering and 0–307 average g fresh weight for ‘Cogshall’) and at different sizes (364–1563 and 276–894 average g fresh weight for ‘Keitt’ and ‘Kent’, respecively). Immediately after harvest (green) or after 1 week of ripening at room temperature (ripe), fruit were homogen...
