Fruit ripening in tomato (Solanum lycopersicum) requires the coordination of both developmental cues as well as the plant hormone ethylene. Although the role of ethylene in mediating climacteric ripening has been established, knowledge regarding the developmental regulators that modulate the involvement of ethylene in tomato fruit ripening is still lacking. Here, we show that the tomato APETALA...

Fruit ripening is a complex, genetically programmed process that occurs in conjunction with the differentiation of chloroplasts into chromoplasts and involves changes to the organoleptic properties of the fruit. In this study, an integrative analysis of the transcriptome and proteome was performed to identify important regulators and pathways involved in fruit ripening in a spontaneous late-rip...

Climacteric fruit ripening, as it occurs in many fruit crops, depends on a rapid, autocatalytic increase in ethylene production. This agriculturally important process has been studied extensively, with tomato simultaneously acting both as a model species and target crop for modification. In tomato, the ethylene biosynthetic genes ACC SYNTHASE2 (ACS2) and ACS4 are highly expressed during fruit r...

The current experiment was carried out to determine the effect of application ethephon on maturation “Peter” figs. Fig fruits were treated with three aqueous concentrations (500, 1000, and 1500 ppm) during developmental stage. physic-chemical characteristics, such as fruit weight, length, diameter, total soluble solids (TSS), acidity recorded analysed. results showed that period fig significant...

Tomato (Solanum lycopersicum L.) is an important vegetable crop and acts as model plant for fruit development studies. Besides that, post-harvest damage is a devastating phenomenon often associated with ripening process in tomato which in turn leads to greater yield loss. Understanding the genetics, molecular and biochemical pathways is the key to overcome the existing situation. In th...

Fruit ripening is a unique aspect of plant development with direct implications for a large component of the food supply and related areas of human health and nutrition. Recent advances in ripening research have given insights into the molecular basis of conserved developmental signals coordinating the ripening process and suggest that sequences related to floral development genes might be logi...

A pear (Pyrus communis L. cv Passe Crassane) cell suspension was used as a model system to study the influence of gibberellin on processes related to fruit ripening. Growth of the cell cultures was inhibited and their loss of viability was accelerated when 0.5 millimolar gibberllic acid (GA(3)) was added to suspensions at two stages of cell development, namely, growth and quiescence. Cell respi...

Fruit ripening in tomato (Solanum lycopersicum) is a complicated development process affected by both endogenous hormonal and genetic regulators and external signals. Although the role of NOR, a member of the NAC domain family, in mediating tomato fruit ripening has been established, its underlying molecular mechanisms remain unclear. To explore further the role of NAC transcription factors in ...

Ethylene is the main regulator of climacteric fruit ripening, by contrast the putative role of other phytohormones in this process remains poorly understood. The present study brings auxin signaling components into the mechanism regulating tomato fruit ripening through the functional characterization of Auxin Response Factor2 (SlARF2) which encodes a downstream component of auxin signaling. Two...
