Interindividual differences in neuronal wiring may contribute to behavioral individuality and affect susceptibility to neurological disorders. To investigate the causes and potential consequences of wiring variation in Drosophila melanogaster, we focused on a hemilineage of ventral nerve cord interneurons that exhibits morphological variability. We find that late-born subclasses of the 12A hemi...

This study was conducted to investigate the effects of different IBA doses on rooting capacity of Cherry laurel (Prunus laurocerasus L.) types in greenhouse conditions under mist propagation unit in 2008 2009. This species has an economic and important value for medicinal and pharmaceutical industry. Determination of suitable conditions for cutting propagation of different types is too importan...

bacteria of the genus azospirillum are well known as plant growth promoting rhizobacteria. the ability to synthesize phytohormones is considered one of the most important mechanisms to promote plant growth and is widely distributed among plant-associated rhizobacteria.the most important phytohormone produced by azospirillum is the auxin indole-3-acetic acid, with the l-tryptophan as the precurs...

Objectives Root resorption is a dangerous side effect in orthodontics, and maxillary incisors are at the highest risk for root resorption. It is important to understand optimal force considerations for patients with altered root lengths.The purpose of this study was to investigate the effects of root length on stress distribution on roots by means of three dimensional fi...

in order to study the effect of sowing date and plant density on some quantitative traits and yield of sugar beet genotypes a field experiment was carried out at sugar beet seed production research station of karaj in 2006. treatments arranged in a split, split plot experiment based on completely randomized block design with four replications. the main factors were two sowing dates as 14 april ...

the research has been done for assessment of effects of different concentrations of indole-3-butyric acid (iba) on rhizogenesis of scions of c. phlomidis in 2010.  the research has been done on randomized complete-blocks for five replications and three treatments with zero, 2000ppm and 3000pmm concentration. different characters such as number of root of each scion, length of root, length of ne...

abstract the lack of water is the most important problem in extensive landscape especially turfgrass in arid and semi arid regions. the root responses in native and commercial grasses under drought stress were investigated. this experiment was in a factorial experiment based on unbalanced completely random design on the year 2006. the specious that we used in this experiment included (i) commer...

In this study, the role of salicylic acid pre-treatment (0.01, 0.1 mM was investigated)in inducing salt tolerance in sweet basil. Results showed germination percentage, length of shoot and root, fresh and dry weight of leaf, and photosynthetic pigments were decreased in response to high salinity but the lipid peroxidation, coefficient allometry, and soluble sugars increased. In plants pre-treat...
