who recommends artemisinin-based combination therapies (acts) as the most effective choice to treat malaria. for developing transgenic plants with high accumulation of artemisinin (by introducing genes encoding enzymes which regulate the biosynthetic pathway of artemisinin), an efficient protocol for tissue culture and plant regeneration is necessary. in the present study, leaf explants of arte...

Lepidosperma prospectum G.T.Plunkett & R.L.Barrett (Cyperaceae tribe Schoeneae) is here described as a new species in the Sydney region of New South Wales. It highly restricted distribution, occurring at Manly (Sydney Harbour National Park), Kamay Botany Bay Park and Royal dense coastal shrublands behind cliffs. These locations are within traditional lands Gamaragal, Gweagal Dharawal people...

The aim of this research was to study the relationships between presence of plant species and environmental factors in Garizat rangelands of Yazd province and providing their predictive habitat models. After delimitation of the study area, sampling was performed using randomized-systematic method. Accordingly, vegetation data including presence and cover percentage were determined in each quadr...

background and objectives: the artemisia genus of asteraceae family is represented by 34 species in iran. artemisia sieberi grows wild in different regions of iran and grows in desert and semi- desert climate and has forage value for animals and also medicinal properties for humans. in this study we examined the antimicrobial effects of a. sieberi. materials and methods: the antimicrobial activ...

Artemisia sieberi (Asteraceae) is an important perennial plant that common in the pastures, mountains and deserts of Iran. In 2019, A. showing little leaf, yellowing, internode shortening witches’-broom symptoms (Fig. 1) were observed around Abarkooh (Yazd province, Iran). The disease incidence was up to 5%. Total DNA extracted from 0.2 g fresh midrib tissue 10 diseased five symptomless plants ...

Predictive modeling of habitat distribution of range plant species and identification of their potential habitats play important roles in the restoration of disturbed rangelands. This study aimed to predict the geographical distribution of Artemisia sieberi and find the influential variables in the distribution of A. sieberi in the desert rangelands of central Iran. Maps of environmental variab...
