A former lectotype for Bromus cincinnatus Ten. (Poaceae) has been superseded, as it is in serious conflict with the protologue. Another element of protologue designated effective lectotype. The new identified coespecific intermedius Guss., a Mediterranean species L. subg. Bromus. combination Helictochloa panormitana (Lojac.) Romero Zarco proposed originally described Avena australis Parl., nom....

Forty-one methanol extracts of 28 indigenous medicinal plant species were tested for their insecticidal bioactivity against cotton whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), adults and second nymphal instars under controlled conditions. This study is within a bioprospection context, in the form of utilizing local plant species as an alternative in sustainable agriculture dev...

Zataria multiflora Boiss known as Avishan Shirazi (in Iran) is one of the valuable Iranian medicinal plants. The aim of study was to evaluate anti-Candida activity of Z. multiflora against different species of Candida in vitro. Anti-Candida activity of the aqueous, ethanolic and methanolic maceration extract of the aerial parts of Z. multiflora Boiss was studied in vitro. Anti-Candida activity ...

Exotic invasive species can directly and indirectly influence natural ecological communities. Cheatgrass (Bromus tectorum) is non-native to the western United States and has invaded large areas of the Great Basin. Changes to the structure and composition of plant communities invaded by cheatgrass likely have effects at higher trophic levels. As a keystone guild in North American deserts, graniv...

environmental stress especially drought is one of the most important factors to reduce and disturbance in different stages of floral growth especially sprouting in dry and semi-dry lands of iran. for this purpose a factorial essay executed in accidentally manner with four iterations in vitro condition. four genotypes of bromus tomentellus pasture types were used (92 tehran, 630 kordestan, 3414 ...

PREMISE OF THE STUDY Bromus tectorum (Poaceae) is an annual grass species that is invasive in many areas of the world but most especially in the U.S. Intermountain West. Single-nucleotide polymorphism (SNP) markers were developed for use in investigating the geospatial and ecological diversity of B. tectorum in the Intermountain West to better understand the mechanisms behind its successful inv...
