Rather than rely upon a large number of hardware components, they favored computation and elegant programming to perform key functions.
Resilient communities have robust, redundant physical and social systems that help them perform key functions under extreme circumstances.
The INM houses a unique set of integral membrane proteins that perform key functions in the organization of intranuclear architecture, control of gene expression and coupling of the nucleus to the cytoskeleton.
Ferrichrome siderophores perform key functions in fungal cells.
RIN [ 70], NOR [ 71] and CNR [ 72] genes encode transcription factors belonging to the MADS-box, NAC-domain, and SBP-box families, respectively, that act upstream of ethylene biosynthesis and perform key functions in the control of fruit ripening [ 73].
Similarly, sequence-based comparisons will tell us nothing about the similarity of two genes which differ in sequence greatly, but perform key functions in the same biological process or pathway.
Absorption, distribution, and excretion of some chemicals can be affected by mechanisms that evolved in specialized cells for transport of physiological molecules and macromolecules, to enable the cells to perform key functions of living organisms.
Although process parameters, substrates and technology differ between the wet and dry biogas fermentations analyzed in this study, community profiles are very similar at least at higher taxonomic ranks, illustrating that core community taxa perform key functions in biomass decomposition and methane synthesis.
Together, these examples demonstrate that cumulus cells perform key functions on behalf of oocytes and act as a nexus by responding to oocyte and maternal stimuli to coordinate oocyte maturation in relation to the reproductive cycle and follicle development (reviewed in Ref. 183).
Candidate effectors are understood to perform key functions prior to host colonization such as the provision of nutrients, mask recognition by the host defense system, cell-to-cell communication, detoxification of the environment, suppression of host-cell programmed cell death and killing of potential competitors [ 13, 45- 48].
