Stian Olsen, Kirsten Krause
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 host-invasive growth of the haustorium. The level of xyloglucan endotransglucosylation (XET) activity was found to peak at the penetrating stage of Cuscuta reflexa on its host Pelargonium zonale...

Natural product screening for new bioactive compounds can greatly benefit from low reagents consumption and high throughput capacity of droplet-based microfluidic systems. However, the creation of large droplet libraries in which each droplet carries a different compound is a challenging task. A possible solution is to use an HPLC coupled to a droplet generating microfluidic device to sequentially encapsulate the eluting compounds. In this work we demonstrate the feasibility of carrying out enzyme inhibiting assays inside nanoliter droplets with the different components of a natural crude extract after being separated by a coupled HPLC column...

Insect vectors are responsible for spreading devastating parasites and pathogens. A large number of botanicals have been suggested for eco-friendly control programs against mosquito vectors, and some of them are aromatic plants. Pelargonium roseum, a species belonging to the Geraniaceae family, due to its pleasant rose-like odor may represent a suitable candidate as mosquito repellent and/or larvicide. In this research, we evaluated the toxicity of the essential oil from P. roseum and its major constituents against the West Nile and filariasis vector Culex pipiens...

Geraniaceae are known for their unusual plastid genomes (plastomes), with the genus Pelargonium being most conspicuous with regard to plastome size and gene organization as judged by the sequenced plastomes of P. x hortorum and P. alternans. However, the hybrid origin of P. x hortorum and the uncertain phylogenetic position of P. alternans obscure the events that led to these extraordinary plastomes. Here, we examine all plastid reconfiguration hotspots for 60 Pelargonium species across all subgenera using a PCR and sequencing approach...

Identification of Pelargonium radula as bioindicator for mercury (Hg) detection confers a new hope for monitoring the safety of drinking water consumption. Hg, like other non-essential metals, inflicts the deterioration of biological functions in human and other creatures. In the present study, effects of Hg on the physiology and biochemical content of P. radula were undertaken to understand the occurrence of the morphological changes observed. Young leaves of P. radula were treated with different concentrations of Hg-containing solution (0...

BACKGROUND: Rose-scented geranium (Pelargonium sp.) is a perennial herb that produces a high value essential oil of fragrant significance due to the characteristic compositional blend of rose-oxide and acyclic monoterpenoids in foliage. Recently, the plant has also been shown to produce tartaric acid in leaf tissues. Rose-scented geranium represents top-tier cash crop in terms of economic returns and significance of the plant and plant products. However, there has hardly been any study on its metabolism and functional genomics, nor any genomic expression dataset resource is available in public domain...

Herein, we report the biosynthesis of Ag NPs, for the first time, using identified antimicrobial molecules (gallic acid+apocynin) and (gallic acid+apocynin+quercetin) from the medicinal plant Pelargonium endlicherianum Fenzl. and dramatically enhanced antimicrobial activity. We also investigate the role of each molecule on formation Ag NPs and explain the increase in the antimicrobial activity of identified molecules mediated Ag NPs. The extraction protocols, 11% ethanol and 70% methanol, resulted in identification of different constituents of gallic acid+apocynin (M1) and gallic acid+apocynin+quercetin (M2) with respective concentrations...

For species with minor inverted repeat (IR) boundary changes in the plastid genome (plastome), nucleotide substitution rates were previously shown to be lower in the IR than the single copy regions (SC). However, the impact of large-scale IR expansion/contraction on plastid nucleotide substitution rates among closely related species remains unclear. We included plastomes from 22 Pelargonium species, including eight newly sequenced genomes, and used both pairwise and model-based comparisons to investigate the impact of the IR on sequence evolution in plastids...

Pelargonium line pattern virus (PLPV, Tombusviridae) normally establishes systemic, low-titered and asymptomatic infections in its hosts. This type of interaction may be largely determined by events related to RNA silencing, a major antiviral mechanism in plants. This mechanism is triggered by double or quasi double-stranded (ds) viral RNAs which are cut by DCL ribonucleases into virus small RNAs (vsRNAs). Such vsRNAs are at the core of the silencing process as they guide sequence-specific RNA degradation Host RNA dependent-RNA polymerases (RDRs), and particularly RDR6, strengthen antiviral silencing by promoting biosynthesis of secondary vsRNAs...
