Changes in gene expression produced by the application of (+)-abscisic acid (ABA) to Arabidopsis thaliana plants were compared with changes produced by the ABA structural analogs (-)-ABA, (+)-8'-acetylene ABA and (-)-2',3'-dihydroacetylenic abscisyl alcohol. The maximum expression of many rapidly (+)-ABA-induced genes occurred prior to peak hormone accumulation, suggesting negative feedback reg...

Although much progress has been made towards understanding the ripening of non-climacteric fruit using the strawberry as a model plant, the defined molecular mechanisms remain unclear. Here, RNA-sequencing was performed using four cDNA libraries around the onset of ripening, and a total of 31,793 unigenes and 335 pathways were annotated including the top five pathways, which were involved in ri...

Fruit ripening is a genetically programmed process. Transcription factors (TFs) play key roles in plant development and ripening by temporarily and spatially regulating the transcription of their target genes. In this study, a total of 159 TFs were identified from a spontaneous late-ripening mutant 'Fengwan' (C. sinensis L. Osbeck) sweet orange (MT) and its wild-type counterpart ('Fengjie 72-1'...

Kiwifruit [Actinidia deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson, cv. "Hayward"] is classified as climacteric fruit and the initiation of endogenous ethylene production following harvest is induced by exogenous ethylene or chilling exposure. To understand the biological basis of this "dilemma," kiwifruit ripening responses were characterized at 20°C following treatments with exogenous ethy...

After-ripening (AR) is a time and environment regulated process occurring in the dry seed, which determines the germination potential of seeds. Both metabolism and perception of the phytohormone abscisic acid (ABA) are important in the initiation and maintenance of dormancy. However, molecular mechanisms that regulate the capacity for dormancy or germination through AR are unknown. To understan...

Ripening of fleshy fruits is a complex process that involves dramatic changes in color, texture, flavor, and aroma, which is essentially regulated by multiple hormone signals. Although the metabolic mechanisms for the regulation of fruit development and ripening have been studied extensively, little is known about the signaling mechanisms underlying this process. FERONIA has been increasingly s...

The NAP (NAC-like, activated by AP3/P1) transcription factor belongs to a subfamily of the NAC transcription factor family, and is believed to have an important role in regulating plant growth and development. However, there is very little information about this subfamily in Rosaceous plants. We identified seven NAP genes in the peach genome. PpNAP2 was categorized in the NAP I group, and conta...

the research was carried out to study the effect of controlled deficit irrigation (cdi) on quality and quantity of sugar beet in bardsir region of kerman and karaj during 2005- 2006. in this experiment, 11 irrigation treatments were studied in a randomized complete block design with three replicates. crop water requirement was calculated in two- day periods. the treatments were implemented in d...

Abscisic acid (ABA) plays a major role in promoting ripening sweet cherry, non-climacteric fruit. Exogenous application of ABA has been performed to study fruit and cracking, but this growth regulator is not used for commercial production. To determine the potential improve cherry quality, canopy spraying was assayed four cultivars. Canopy S-ABA significantly: (1) enhanced color ‘Glenred’, ‘Lap...
