OBJECTIVE Sweet potato whitefly, Bemisia tabaci Gen. (B. tabaci), is one of the most important pests of various greenhouse crops in Iran. Nowadays, chemical insecticides are broadly used for control of the pests that causes risk to consumer's health. For the first time, contact toxicity of Pelargonium roseum Andrews and Artemisia sieberi Besser essential oils on B. tabaci and its possible appli...

The mechanisms that regulate mitochondrial inheritance are not yet clear, even though it is 100 years since the first description of non-Mendelian genetics. Here, we quantified the copy numbers of mitochondrial DNA (mtDNA) in the gametic cells of angiosperm species. We demonstrate that each egg cell from Arabidopsis thaliana, Antirrhinum majus, and Nicotiana tabacum possesses 59.0, 42.7, and 73...

BACKGROUND Staphylococcus aureus is one of the most causative organisms in the skin wound infections. Development of resistant S. aureus to current treatments in individuals with low immunity is a global concern. The aim of this study was to evaluate the efficacy of herbal formulation against skin wound infection. METHODS The efficacy of herbal formulation containing Oliveria decumben...

The effectiveness of 7 fungicides (Amistar 250 SC, Bayleton 5 WP, Bumper 250 EC, Discus 500 WG, Folicur BT 225 EC, Folicur Multi 50 WG, Score 250 EC) and 2 bioproducts (Biochikol 020 PC and Biosept 33 SL) in the control of Puccinia pelargonii-zonalis was tested on pelargonium cv. Pulsar F1 Salmon. Additionally, their influence on plant growth, size of pustules, percentage of germinated spores a...

The parasitic vines of the genus Cuscuta form haustoria that grow into other plants and connect with their vascular system, thus allowing the parasite to feed on its host. A major obstacle that meets the infection organ as it penetrates the host tissue is the rigid plant cell wall. In the present study, we examined the activity of xyloglucan endotransglucosylases/hydrolases (XTHs) during the ho...

Overall phylogenetic relationships within the genus Pelargonium (Geraniaceae) were inferred based on DNA sequences from mitochondrial(mt)-encoded nad1 b/c exons and from chloroplast(cp)-encoded trnL (UAA) 5' exon-trnF (GAA) exon regions using two species of Geranium and Sarcocaulon vanderetiae as outgroups. The group II intron between nad1 exons b and c was found to be absent from the Pelargoni...
