The fungal toxin fusicoccin induces plant wilting by affecting ion transport across the plasma membrane of plant cell. The activity of this toxin is so far unknown in humans. In the present study we show that fusicoccin is able to affect the platelet aggregation process. The toxin associates with platelet intracellular binding sites and induces aggregation in platelet-rich plasma in a dose-depe...

A new methodology is presented that allows the upscaling of land surface parameters of a Soil-VegetationAtmosphere-Transfer (SVAT) Model. Focus is set on the proper representation of latent and sensible heat fluxes on grid scale at underlying subgrid-scale heterogeneity. The objective is to derive effective land surface parameters in the sense that they are able to yield the same heat fluxes on...

Increasing drought is one of the most critical challenges facing species and ecosystems worldwide, and improved theory and practices are needed for quantification of species tolerances. Leaf water potential at turgor loss, or wilting (π(tlp) ), is classically recognised as a major physiological determinant of plant water stress response. However, the cellular basis of π(tlp) and its importance ...

The assumption that seeds imbibe most of the water required for germination as liquid through seed-to-soil contact has been a dominant theme in germination research and seeding technology. Under most conditions, seeds are also exposed to water vapour during imbibition, but the relative contributions of liquid and vapour are difficult to assess. In water uptake models that include vapour, proced...

Antifungal potential of aqueous extracts of forty plants of different families were tested against Fusarium oxysporum f.sp. ciceri causal agent of wilting of chick pea. Among forty plant species tested aqueous extract of Chenopodium ambrosioides has recorded significant antifungal activity against the test fungi. Solvent extracts viz. petroleum ether, benzene, chloroform, and methanol and ethan...

An isolate of Bursaphelenchus xylophilus from Pinus sylvestris in Missouri infected and reproduced in 2-3-year-old seedlings of P. sylvestris and to some extent in seedlings of P. nigra. Wilting, however, occurred only in P. sylvestris. B. xylophilus isolated from P. strobus in Vermont infected and reproduced only in P. strobus seedlings. P. taeda seedlings were resistant to both of these isola...

Alyceclover (Alysicarpus spp.) is an annual, high-quality leguminous forage, suitable for production under tropical and subtropical climates where the husbandry of conventional leguminous forages, Trifolium spp., is uneconomical. The damage potential and reproduction of Belonolairaus longicaudatus and Hoplolaimus galeatus on alyceclover were studied under greenhouse conditions, using sand and s...

This research examines the effects of two irrigation strategies on water use efficiency and fruit yield components ‘Royal Gala’ ‘Brookfield apple orchards in south-central Chile. The study was carried out during 2008–2009 2009–2010 growing seasons at sites. A randomized block experimental design established with application treatments: theoretical volume required by plant (T1) farm protocol (T2...
