Symbiotic bacteria enable olive fly larvae to overcome host defences
Ripe fruit offer readily available nutrients for many animals, including fruit fly larvae (Diptera: Tephritidae) and their associated rot-inducing bacteria. Yet, during most of their ontogeny, fruit remain chemically defended and effectively suppress herbivores and pathogens by high levels of secondary metabolites. Olive flies (Bactrocera oleae) are uniquely able to develop in unripe olives. Un...
متن کاملSymbiotic Bacteria Protect Wasp Larvae from Fungal Infestation
Symbiotic associations between different organisms are of great importance for evolutionary and ecological processes [1-4]. Bacteria are particularly valuable symbiotic partners owing to their huge diversity of biochemical pathways that may open entirely new ecological niches for higher organisms [1-3]. Here, we report on a unique association between a new Streptomyces species and a solitary hu...
متن کاملLocalization of Neuropeptide Gene Expression in Larvae of an Echinoderm, the Starfish Asterias rubens
Neuropeptides are an ancient class of neuronal signaling molecules that regulate a variety of physiological and behavioral processes in animals. The life cycle of many animals includes a larval stage(s) that precedes metamorphic transition to a reproductively active adult stage but, with the exception of Drosophila melanogaster and other insects, research on neuropeptide signaling has hitherto ...
متن کاملTroponin-I is present as an essential component of muscles in echinoderm larvae
The troponin complex, composed of Troponin-I, Troponin-T and Troponin-C, is an essential mediator of the contraction of striated muscle downstream of calcium signaling in almost all bilaterians. However, in echinoderms and hemichordates, collectively termed Ambulacraria, the components of the troponin complex have never been isolated, thus suggesting that these organisms lost the troponin syste...
متن کاملTemporal and spatial distribution patterns of echinoderm larvae in La Parguera, Puerto Rico.
This study describes temporal and spatial abundance patterns of echinoderm larvae in La Parguera, Puerto Rico. For the temporal study, larvae were sampled by a series of monthly tows taken with a 64 microm mesh net between the new and full moon from April 2005 to July 2006, September 2006 and August 2007. In order to measure spatial variation of echinoderm larval abundances, oblique tows were t...
