A Non-Climacteric Fruit Gene CaMADS-RIN Regulates Fruit Ripening and Ethylene Biosynthesis in Climacteric Fruit
MADS-box genes have been reported to play a major role in the molecular circuit of developmental regulation. Especially, SEPALLATA (SEP) group genes play a central role in the developmental regulation of ripening in both climacteric and non-climacteric fruits. However, the mechanisms underlying the regulation of SEP genes to non-climacteric fruits ripening are still unclear. Here a SEP gene of ...
متن کاملRegulation of tomato fruit ripening
Fruit ripening is a sophisticatedly orchestrated developmental process, unique to plants, that results in major physiological and metabolic changes, ultimately leading to fruit decay and seed dispersal. Because of their strong impact on fruit nutritional and sensory qualities, the ripeningassociated changes have been a matter of sustained investigation aiming at unravelling the molecular and ge...
متن کاملClimacteric fruit ripening: Ethylene-dependent and independent regulation of ripening pathways in melon fruit
Cantaloupe melons have a typical climacteric behaviour with ethylene playing a major role in the regulation of the ripening process and affecting the ripening rate. Crossing of Cantaloupe Charentais melon with a non-climacteric melon indicated that the climacteric character is genetically dominant and conferred by two duplicated loci only. However, other experiments made by crossing two non-cli...
متن کاملEthylene feedback mechanisms in tomato and strawberry fruit tissues in relation to fruit ripening and climacteric patterns
Exposing pericarp tissue excised from immature tomato fruit to 4.5 mmol l C2H4 revealed a negative C2H4 feedback mechanism in relation to its biosynthesis since ACC concentration and C2H4 production by the tissue were reduced. An opposite trend (positive C2H4 feedback mechanism) was observed in pericarp tissue excised from fruit at the pink stage. At the mature-green stage however, tissue showe...
متن کاملRegulation of climacteric respiration in ripening avocado fruit.
Ripening of avocado fruit is associated with a dramatic increase in respiration. In vivo(31)P nuclear magnetic resonance spectroscopy revealed large increases in ATP levels accompanying the increase in respiration. Both glycolytic enzymes, phosphofructokinase, and pyrophosphate: fructose-6-phosphate phosphotransferase were present in avocado fruit with the latter activity being highly stimulate...
