Proline degradation by proline dehydrogenase/proline oxidase (PRODH/POX) contributes to apoptosis or autophagy. The identification of specific pathway of apoptosis/survival regulation is the aim of this study. We generated knocked-down PRODH/POX MCF-7 breast cancer cells (MCF-7shPRODH/POX). PRODH/POX silencing did not affect cell viability. However, it contributed to decrease in DNA and collage...

Proline accumulation was often correlated with drought tolerance of plants infected by arbuscular mycorrhizal fungi (AMF), whereas lower proline in some AM plants including citrus was also found under drought stress and the relevant mechanisms have not been fully elaborated. In this study proline accumulation and activity of key enzymes relative to proline biosynthesis (▵(1)-pyrroline-5-carboxy...

The transfer of cultured tomato cells (Lycopersicon esculentum cv VFNT-Cherry) to a low water potential environment resulted in an increased dry weight to fresh weight ratio accompanied by a rapid accumulation of proline. Proline content continued to increase as osmotic adjustment and growth occurred. The initial increase in proline concentration was accompanied by a drop in turgor. However, pr...

Root exudates have important, yet incompletely known, roles in plant physiology, mainly in rhizosphere interactions with other organisms. Proline might play a critical role in protecting plants under stress, particularly under saline conditions. However, as far as we know, no attempts have been made to determine the proline content of root exudates. Here, we present preliminary results of the q...

in order to study the effects of foliar application of zn and k on yield and some physiological traits of spring safflower (carthamus tinctorius l.), cv. esfahan 14, under drought stress, a pot experiment was conducted in research greenhouse of yasouj university. experiment was a factorial based on completely randomized design with three replications. factors consisted of drought stress (s1- wi...

a hydroponic experiment was conducted to evaluate the effects of salt stress on safflower genotypes under greenhouse conditions. the experiment was arranged as a factorial one based upon a completely randomized design with three replications. five safflower genotypes (arak2811, nebraska10, sod25, ca116, and ca128), and four salinity treatments (0, 0.3, 0.5, and 0.7 percent of nacl) were employe...

This study was conducted in two phases: 1) to investigate the effect of drought stress on relative water content and proline of leaf and 2) to evaluate the effect of drought stress and potassium concentrations in nutrient solution on the lily (Lilium longifolium × Asiatic cv. Termoli). Based on a completely randomized design in mixture of sand and perlite medium and in three levels of potassium...
