We have demonstrated that low concentrations of ethanol vapor efficiently induce the alc gene expression system in tobacco (Nicotiana tabacum cv Samsun NN), potato (Solanum tuberosum cv Solara), and oilseed rape (Brassica napus cv Westar). For many situations, this may be the preferred method of induction because it avoids direct application of comparatively high concentrations of an ethanol so...

Leaves exhibit a wide range of form and function: as well as the flattened photosynthetic organs we are most familiar with, modifications of leaf morphology produce the rigid spines of cacti, the cup-shaped insect traps of pitcher plants, colorful flower parts such as petals and some of the tendrils used for attachment by climbing plants. One fundamental choice in leaf architecture is whether t...

A major portion of the Iranian fig (Ficus carica) industry is located in high-salinity regions, and salinity is an important limiting factor in the production of this fruit. The present study was conducted to investigate the changes of leaf antioxidant-enzyme activity, proline and total protein content in two fig cultivars with two leaf shapes: ‘Anjir Sabz’ with lobate and palmate leaves, and ‘...

In this work, cuticular waxes from flag leaf blades and peduncles of Triticum aestivum cv. Bethlehem were investigated in search for novel wax compounds. Seven wax compound classes were detected that had previously not been reported, and their structures were elucidated using gas chromatography-mass spectrometry of various derivatives. Six of the classes were identified as series of homologs di...

MAHMOOD, I., A. RAZZAQ, M. RASHEED, A. QAYYUM and M. AHMAD, 2014. Employment of immature embryo culture for in vitro selection of drought tolerant somaclones of wheat. Bulg. J. Agric. Sci., 20: 155-161 Drought, a serious threat to world agriculture, demands neo-breeding approaches. Tissue culture being a mutagenic process induces somaclonal variations, which can be manipulated for improving dro...

INTRODUCTION Lowering of low density lipoprotein (LDL) cholesterol (LDL-C) has been shown to be associated with significant reduction of adverse cardiovascular (CV) events. The 2013 ACC/AHA guidelines recommend high-intensity statin therapy to lower LDL-C levels by$ 50% with no specific target goal for adults at high risk for atherosclerotic CV diseases, andmoderate-intensity statin therapy to ...

Pulmonary arterial hypertension (PAH) is one of the common conditions primarily affecting right heart and promoting atrial fibrillation (AF), but mechanisms are poorly understood. This study aimed to use multi-scale models investigate by which (RA) remodeling facilitates perpetuates arrhythmias. We have developed single-cell-to-tissue-level computer mimic control disease incorporating most rece...

High throughput assays have been developed to measure the ice nucleation activity of transgenic tobacco, Nicotiana tabacum L. cv. Petit Havana SR1 plants expressing the ice nucleation gene, inaZ, from Pseudomonas syringae at a young seedling stage, as well as in leaf tissue. Both assays are carried out in 96-well microtitre plates. The first assay involves direct seeding in vitro, one seed per ...

Ecophysiological characteristics of "Ahmadaghaii" "Ohadi" "Kallehghuchi" cultivars (as scions) on four pistachio rootstocks (Pistacia vera Cv. Badami riz, P. vera Cv. Sarakhs, P. atlantica sub sp. Mutica, P. atlantica sub sp. Atlantica) were evaluated during the spring and summer seasons of 2005 in the Iran's Pistachio Research Institute (IPRI). Ecophysiological characteristics such as photosyn...
