This study of the whitefly Bemisia tabaci and two bacteria (Portiera aleyrodidarum and Hamiltonella defensa) cohoused in each host cell investigated whether the decay of Portiera metabolism genes is complemented by host and Hamiltonella genes, and compared the metabolic traits of the whitefly symbiosis with other sap-feeding insects (aphids, psyllids, and mealybugs).
To investigate whether these viral tRNAs complemented the host tRNA pool to render it better adapted to viral amino acid requirements, we compared the ratio of host tRNAs per viral amino acid 1) for the 15 amino acids that had no viral tRNA versus the 2) the five amino acids with one viral tRNA.
Bacteroidetes degraded high-molecular-weight organic matter, such as protein and carbohydrates, and complemented the host genome to degrade resistant foods such as plant cell wall compounds (including cellulose, pectin, and xylan) (Thoetkiattikul et al. 2013).
Presenting the guidelines on Monday he said "mobile workers complement host country workers by helping to address skills gaps and labour shortages - in other words they tend not to take jobs away from host country workers".
S. epidermidis rather than acting alone, is able to kill pathogens by complementing the host's innate immune system.
Although the two BPL_N encoding genes have acquired introns (supplementary fig. S9, Supplementary Material online), they are likely not complementing any host deficiency related to biotin ligation that is associated with eukaryotic BirA proteins that carry the BPL_N domain.
Under selection for translational optimization in the virus, we might hypothesize that 1) the additional tRNAs correspond to optimal codons in the viral genome and/or 2) the additional tRNAs correspond to the most abundant amino acids in the virus and/or 3) they complement the host tRNA pool to optimize viral protein translation.
As primary endosymbionts are most often involved in complementing the host's diet, this finding suggests that this bacterium might have been lost during adulthood by a few males and hence, that it might be essential to the larval rather than the adult stage [ 59].
Transformation of aromatic hydrocarbons has also been attained by heterologous expression of the terminal oxygenase components using non-specific ET proteins complemented by the host strain (Mukerjee-Dhar et al. 2005).
This is complemented by a host of tactics that in other circumstances might be called bribes.
