Identification and analysis of new phloem proteins from Brassicaceae and Cucurbitaceae
… aim of this work was the identification of new phloem sap proteins and a metabolic characterisation of this transport fluid. The experiments were performed on the three plant species C. sativus, C. maxima and B. napus. To characterise the phloem samples from B. napus, a new model plant for …

Influence of feeding-location on nutritional quality for cochineal insects (Homoptera : Dactylopiidae) on Opuntia ficus-indica (Cactaceae)
… possible explanation for the disparity in size. Phloem sap was collected from the severed stylets of cochineal insects and analysed for polyphenols (which inhibit growth) and amino acids (responsible for growth). The indication from the polyphenol analysis was that it was not responsible for …

The dynamics of molecular components that regulate aphid-plant interactions
… important insect pests, which feed on phloem sap using stylets. Aphids cause significant losses of crop yield, through draining plant resources and vectoring over 275 plant viruses. In plant-pathogen interactions, basal plant defense involving pathogen associated molecular pattern …

Spatio-temporal analysis of florigenic signals in Arabidopsis thaliana, Sinapis alba and Brassica napus
… signal is transduced to the shoot apex via the phloem to induce flowering remains to be elucidated. This study aimed at the identification of new candidates involved in the induction of flowering by employing three plant species, Arabidopsis thaliana, Sinapis alba and Brassica napus in …

Plasticity of Primary Metabolism in Parasitic Orobanchaceae
… which has decreased levels of asparagine in the phloem sap compared to the wild type. However, altered amino acid levels in other lines did not impact P. aegyptiaca growth, indicating that this parasite has ability to compensate for variation in host metabolic composition. This research …

Behavior and Ecology of Wild Slow Lorises (Nycticebus coucang): Social Organization, Infant Care System, and Diet
… food: floral nectar and nectar-producing parts, phloem sap, fruits, gums (another group of plant exudates), and arthropods. The largest proportion of feeding time was spent on phloem sap (34.9%), floral nectar and nectar-producing parts (31.7%), and fruits (22.5%). These food types should provide …

Exploring Chemically Mediated Interactions Between Spotted Lanternfly, Lycorma delicatula, and Its Host Plants in the Mid-Atlantic Region of the United States
… (Hemiptera: Fulgoridae), is a polyphagous phloem feeding planthopper introduced to the United States in 2014. Now established in 19 states, its aggregations, persistent feeding, and honeydew threaten specialty crops, especially wine grapes. Management often relies on insecticides and …

Zur Bedeutung von Saccharose-Transportern in Pflanzen mit offener Phloemanatomie
… Nährstoffe, wie z.B. Zucker, durch ein als Phloem bezeichnetes Transportgewebe. Der Langstreckentransport zwischen verschiedenen Teilen der Pflanze ist essentiell für deren Entwicklung und Ertragsbildung. Nach bisheriger Lehrmeinung gibt es zwei Wege, wie die Metabolite, insbesondere …
