Developmental transitions in some parasitic angiosperms are tied directly to host-derived chemical cues (xenognosins). The obligate hemi-parasite Striga asiatica, initiates the root apical meristem population (germination), development of the host attachment organ (the haustorium), and shoot apical meristem initiation (seed coat shedding) in response to specific xengonosins. These checkpoints s...
ABSTRACT Striga gesnerioides is a root hemiparasite of wild and cultivated legumes, among which cowpea (Vigna unguiculata) and Indigofera hirsuta are suitable hosts. In this study, we examined the genetic structure and host-parasite interaction of a strain of S. gesnerioides parasitizing I. hirsuta (SGFL) from central Florida (United States). Amplified fragment length polymorphism analysis was ...
This article documents the addition of 396 microsatellite marker loci to the Molecular Ecology Resources Database. Loci were developed for the following species: Anthocidaris crassispina, Aphis glycines, Argyrosomus regius, Astrocaryum sciophilum, Dasypus novemcinctus, Delomys sublineatus, Dermatemys mawii, Fundulus heteroclitus, Homalaspis plana, Jumellea rossii, Khaya senegalensis, Mugil ceph...
The map and the model designed by a designer and presented to a manufacturer in the form of a map is the result of his knowledge and innovation. The manufacturer, in turn, uses his best effort to produce a part accordingly. However, because of production problems and raw material, producing a precise part is very difficult and costly. One of the most important problems in this regard is designi...
introduction: several researches have reported that stress is able to inhibit the development of morphine tolerance via activating of hypothalamic-pituitary-adrenal (hpa) axis. in the present study we tried to examine the effect of epinephrine, the product of adrenal medulla, on the development of morphine tolerance. methods: analgesic tolerance was induced by intrathecal (i.t.) injection of mo...
Introduction: Ultra low dose (ULD) morphine induces hyperalgesia which is mediated by excitatory Gscoupled opioid receptors. This study was designed to investigate the development of tolerance to hyperalgesic effect of morphine. Also we attempt to seek possible similarity, in view of Gs proteins, between hyperalgesic effect of ULD and hyperalgesic effect after tolerance to HD. Method: Male ...
This paper describes the 'push-pull' or 'stimulo-deterrent diversionary' strategy in relation to current and potential examples from our own experiences. The push-pull effect is established by exploiting semiochemicals to repel insect pests from the crop ('push') and to attract them into trap crops ('pull'). The systems exemplified here have been developed for subsistence farming in Africa and ...
