Drought is a serious problem that causes losses in crop-yield every year, but the mechanisms underlying how roots respond to water deficit are difficult to study under controlled conditions. Methods for assaying root elongation and architecture, especially for seedlings, are commonly achieved on artificial media, such as agar, moistened filter paper, or in hydroponic systems. However, it has be...

Root system traits are important in view of current challenges such as sustainable crop production with reduced fertilizer input or in resource-limited environments. We present a novel approach for recovering root architectural parameters based on image-analysis techniques. It is based on a graph representation of the segmented and skeletonized image of the root system, where individual roots a...

in order to study the effect of soil compaction on root and shoot growth of wheat plants (shahriar variety), a greenhouse pot experiment was conducted in guilan university. the study design was factorial with completely randomized in three replications. treatments included three compaction levels; (normal compaction, compaction of ten percent and twenty percent) and two type of soil texture (cl...

Wolf tooth is a common term used to describe the first premolar, a functionless remnant from modern horse’s ancestors. This study was performed to reveal possible relationships between morphometric characteristics of wolf tooth and its clinical importance in animal’s health. A total of 158 wolf teeth were extracted from 83 horses from 1.5 to 15 years of age during a period of one year and divid...

introduction proteins are one of the basic and essential required compounds for life, and the creatures receive it either from a plant or animal origin. it has been reported that the positive effects caused by applying the magnetic field are due to the paramagnetic properties of the cells within the plant, and pigments such as the chloroplast. biophysical methods (magnetic fields, electricity, ...

optimization of the condition for pcr-directed sequencing of microsatellites poly adenine (a) length polymorphisms is more difficult and sensitive compared with other common sequences. replication slippage may occur for polymerase enzyme during microsatellite amplification and direct sequencing of these pcr products will be challenging for heterozygote samples. so, the aim of this study is to i...
