kochia is one of those plants which have capability to grow in different environments and can be used as a valuable plant to produce biomass and seed. the purpose of this study was to evaluate the possibility of kochia planting in different dates as well as its resistance to cold weather of mashhad winter. seven sowing dates including 10th october, november, march, april, may, june and july and...
For investigation deficit irrigation and nitrogen application effect on nutrients uptake of henna ecotypes, this research was conducted in the form of split-split-plot on the basis of randomized complete block design with four replications in the Research Field of Islamic Azad University, Jiroft, Iran in 2013-2014. The main, sub and sub-sub plot were deficit irrigation (100, 75 and 50% of ...
Natural Variation in Stomatal Responses to Environmental Changes among Arabidopsis thaliana Ecotypes
Stomata are small pores surrounded by guard cells that regulate gas exchange between plants and the atmosphere. Guard cells integrate multiple environmental signals and control the aperture width to ensure appropriate stomatal function for plant survival. Leaf temperature can be used as an indirect indicator of stomatal conductance to environmental signals. In this study, leaf thermal imaging o...
Despite no obvious barriers to gene flow in the marine realm, environmental variation and ecological specializations can lead to genetic differentiation in highly mobile predators. Here, we investigated the genetic structure of the harbour porpoise over the entire species distribution range in western Palearctic waters. Combined analyses of 10 microsatellite loci and a 5085 base-pair portion of...

Salvia L. genus has antibacterial, antioxidant, antidiabetic and culinary properties. This genus consists of 55 species including 17 endemic ones in Iran. Out crossing and widespread distribution of Salvia L. genus plants have led to great impact on their morphological variation of ecotypes. This study was conducted for investigating morphological variation as well as characters relationsh...
Previous research has shown that sequences of 16S rRNA genes and 16S-23S rRNA internal transcribed spacer regions may not have enough genetic resolution to define all ecologically distinct Synechococcus populations (ecotypes) inhabiting alkaline, siliceous hot spring microbial mats. To achieve higher molecular resolution, we studied sequence variation in three protein-encoding loci sampled by P...
background: the rate of nosocomial infection appears to depend on whether it is calculated using the center for disease control (cdc) or carrier state criteria. the objective of this study was to differentiate between primary endogenous (pe), secondary endogenous (se) and exogenous (ex) infections, and to compare this classification with cdc criteria for nosocomial infections. methods: children...
fennel is one of the oldest herbs and possesses appealing flavor and beneficial medicinal effects. fennel(foeniculum vulgare mill.) belongs to the apiaceae family and its essential oil and seeds are used to flavor foods including meats, ice cream, candy, baked goods and condiments. the increasing commercial value of fennel necessitates the need to develop elite ecotypes with high essential oil ...
