Expansins are proteins that induce extension in isolated plant cell walls in vitro and have been proposed to disrupt noncovalent interactions between hemicellulose and cellulose microfibrils. Because the plant primary cell wall acts as a constraint to cell enlargement, this process may be integral to plant cell expansion, and studies of expansins have focused on their role in growth. We report ...

The effect of pectic oligomers and 1-aminocyclopropane carboxylic acid on ethylene biosynthesis and color change was studied in ripening tomato pericarp discs excised from mature-green tomato fruit (Lycopersicon esculentum Mill.). Pectic oligomers induced at least four distinct responses when added to pericarp discs: (a) a short-term, transient increase in ethylene biosynthesis; (b) a long-term...

Low fat dry fermented sausages were manufactured using controlled ripening conditions and a slow fermented process. The effect of fat content and ripening time on the chemical, colour, texture parameters and sensory acceptability was studied. The fat reduction in slow fermented sausages produced an increase in the pH decline during the first stage of the process that was favoured by the higher ...

Polycomb-group (PcG) protein MULTICOPY SUPPRESSOR OF IRA1 (MSI1) protein is an evolutionarily conserved developmental suppressor and plays a crucial role in regulating epigenetic modulations. However, the potential role and function of MSI1 in fleshy fruits remain unknown. In this study, SlMSI1 was cloned and transformed into tomato to explore its function. The quantitative real-time PCR result...

The purpose of this study was to review systematically randomized controlled trials that were associated with cervical ripening. We identified randomized controlled trials that compared the use of Foley catheter, with or without extraamniotic saline solution infusion, Laminaria, or hygroscopic dilators for cervical ripening or induction with pharmacologic agents or placebo. Randomized controlle...

effects of gibberellic acid (ga) and abscisic acid (aba) on dormant and after-ripened wheat seed, cultivar rl4137, were studied. the aim of the study was to evaluate the effects of seed after-ripening in comparison with gibberellin application on breaking of seed dormancy. moreover, the effect of abscisic acid on dormancy induction was also evaluated. acid and alkaline posphatase activity of se...

role of labor induction has increased in the last decade due to the ‎early detection of fetal jeopardy. although very useful, oxytocin alone is not always successful for induction of ‎labor. in a randomized clinical ‎trial we compared vaginal dinoprostone plus oxytocin with oxytocin alone for ‎induction of labor in 91 ‎pregnant women at 40 weeks or greater gestation with bishop scores ≤ 4. fort...

labor induction despite an unriped cervix is one of the most common indications of the use of prostaglandines. this clinical trial was performed to compare the effectiveness of oxytocin with misoprostol for induction of labor in bahonar hospital, kerman/iran from 1999 to 2000. sixty pregnant women with indication for labor induction were randomly assigned to receive misoprostol or oxytocin. mis...

Pawpaw fruit were harvested at the advent of the ripening process and were ripened at room temperature. Based on fruit fi rmness and respiration and ethylene production rates at harvest and during ripening, fruit were classifi ed into one of four categories: preripening (no to very slight loss of fi rmness; preclimacteric), early ripening (some softening; increasing rates of ethylene and CO2 pr...

In this research, the accelerated ripening of the Kabkab dates from Khalal to Tamr using NaCl and acetic acid solutions was studied. Fruits at Khalal stage were harvested and washed with distilled water before being treated with ripening inducers: 1. NaCl solutions, 2. acetic acid solutions and 3. Aqueous solution of NaCl (1%) and acetic acid. moisture, pH, colour, brix and textural firmness of...
