Effect of nutrient supply on photosynthesis and pigmentation to short-term stress (UV radiation) in Gracilaria conferta (Rhodophyta).
The effects of increased photosynthetic active radiation (PAR), UV radiation (UVR), and nutrient supply on photosynthetic activity, pigment content, C:N ratio and biomass yield were studied in tank cultivated Gracilaria conferta (Rhodophyta). Electron transport rate (ETR) and biliprotein content were higher under high nutrient supply (HNS), obtained from fishpond effluents, compared to low nutr...
متن کاملParasitoids as vectors of facultative bacterial endosymbionts in aphids.
Heritable bacterial endosymbionts play an important role in aphid ecology. Sequence-based evidence suggests that facultative symbionts such as Hamiltonella defensa or Regiella insecticola also undergo horizontal transmission. Other than through male-to-female transfer during the sexual generation in autumn, the routes by which this occurs remain largely unknown. Here, we tested if parasitoids o...
متن کاملOn the facultative requirement of the bacterial RNA chaperone, Hfq.
The pleiotropic post-transcriptional regulator Hfq is an RNA chaperone that facilitates pairing interactions between small regulatory RNAs (sRNAs) and their mRNA targets in several bacteria. However, this classical pattern, derived from the Escherichia coli model, is not applicable to the whole bacterial kingdom. In this article we discuss the facultative requirement for Hfq for sRNA-mRNA duple...
متن کاملCo-evolutionary dynamics of a host-parasite interaction model: obligate versus facultative social parasitism
Host-parasite co-evolution can have profound impacts on a wide range of ecological and evolutionary processes, including population dynamics, the maintenance of genetic diversity, and the evolution of recombination. To examine the co-evolution of quantitative traits in hosts and parasites, we present and study a co-evolutionary model of a social parasite-host system that incorporates (1) ecolog...
متن کاملFacultative bacterial symbionts in aphids confer resistance to parasitic wasps.
Symbiotic relationships between animals and microorganisms are common in nature, yet the factors controlling the abundance and distributions of symbionts are mostly unknown. Aphids have an obligate association with the bacterium Buchnera aphidicola (the primary symbiont) that has been shown to contribute directly to aphid fitness. In addition, aphids sometimes harbor other vertically transmitte...
