How can you use “symbiotic” in a sentence? Here are some example sentences to help you improve your vocabulary:
Our analyses of prokaryotic and eukaryotic genomic sequence data support two symbiotic events in the origin of eukaryotes: one premitochondrial (2.
If two or more symbiotic events were involved, this does not necessarily confirm that any of the living lineages of amitochondriate eukaryotes arose prior to the second (mitochondrial) event.
This is illustrated by the numerous observations of adaptive gene amplifications in response to antibiotics [ 31, 32, 33], anticancer drug treatments and exposure to various toxins [ 34, 35, 36, 37, 38, 39] or heavy metals [ 40, 41, 42, 43, 44], nutrient limitations [ 32, 33, 45, 46, 47, 48, 49, 50], pesticide treatments [ 51, 52, 53], extreme temperatures [ 54, 55] and symbiotic and parasitic interactions [ 56, 57].
Until about five years ago, it was generally accepted that there was a prior period (before mitochondria) in the history of eukaryotes [ 2 26 ] . The basal position of eukaryotes lacking mitochondria (amitochondriate) in phylogenetic trees [ 27 ] was consistent with this supposition as was evidence from sequence signatures [ 6 ] . However, molecular phylogenetic studies of several proteins in recent years have suggested that some or all amitochondriate eukaryotes once possessed mitochondria in the past [ 9 ] . Based on this new evidence, most current models for the origin of eukaryotes assume only a single symbiotic or fusion event between an archaebacterium and an α-proteobacterium [ 8 28 29 ] .
The latter is believed to have occurred only in cyanobacteria [ 10 ] and preceded the symbiotic event leading to the mitochondrion of eukaryotes.
