Tomato (Solanum lycopersicum) is an established model to study fleshy fruit development and ripening. Tomato ripening is regulated independently and cooperatively by ethylene and transcription factors, including nonripening (NOR) and ripening-inhibitor (RIN). Mutations of NOR, RIN, and the ethylene receptor Never-ripe (Nr), which block ethylene perception and inhibit ripening, have proven to be...

The involvement of ethylene in fruit ripening is well documented, though knowledge regarding the crosstalk between ethylene and other hormones in ripening is lacking. We discovered that AUXIN RESPONSE FACTOR 2A (ARF2A), a recognized auxin signaling component, functions in the control of ripening. ARF2A expression is ripening regulated and reduced in the rin, nor and nr ripening mutants. It is a...

The ripening durations and ingredients for the Salchichon sausages were modified to increase pork rear leg consumption by Korean consumers. The salchichon, a ripened pork sausage, was produced to evaluate the efficacy of two different ripening durations with and without rosemary powder on salchichon sausage quality, and the treatments were: i) 45 days of ripening without rosemary, ii) 60 days o...

BACKGROUND Panax ginseng is a famous traditional medicine in Korea for its beneficial effect on obesity, cardiac and liver associated diseases. The aim of this study was to investigate the metabolite in Panax ginseng (P. ginseng, Aralicaceae) berries depending on the ripen stages and evaluate its potential inhibition on adipocyte differentiation in 3 T3-L1 cells. METHODS Different ripening st...

We have studied the transcription of polygalacturonase (PG) and several other riponing-associated genes in wild-type tomato (Lycopersicon esculentum) fruit and three ripening-impaired mutants, rin, nor, and Nr. In wild-type fruit, the PG gene becomes transcriptionally active early in ripening and remains transcriptionally active during the ripening process. Fruit of the three ripening-impaired ...

We propose that semiflexible polymers in poor solvent collapse in two stages. The first stage is the well known formation of a dense toroidal aggregate. However, if the solvent is sufficiently poor, the condensate will undergo a second structural transition to a twisted entangled state, in which individual filaments lower their bending energy by additionally orbiting around the mean path along ...

this study was done to evaluate the effects of harvest time on some factor of ‘ahmadaqaie’ pistachio nuts in rafsanjan. in three consecutive years (2009-2012) during three stages of friut ripening (40, 70 and 100 percent of hulling), fruit was harvested and physiological and biochemical parameters were measured. the experiments were conducted as randomized complete block design with compound an...

For production of high quality grape berries, the whole cluster should ripen at one time. The lack of uniform ripening within a cluster is termed "uneven ripening," and is characterized by the presence of green berries in an otherwise mature ripe cluster. Uneven ripening of 'Concord' is a major problem in the South, often prohibiting production. Northwest Arkansas is the southern boundary for c...

Temporal changes in total flavonoid content (TFC), composition, free radical scavenging activity and metabolism-related gene expression of three Prunus humilis cultivars with distinctively different fruit colors were investigated this study. The highest TFCs all observed at the initial sampling stage (young-fruit stage, YFS), which then declined gradually until ripening. dark-red-fruited cultiv...
