How can you use “spore” in a sentence? Here are some example sentences to help you improve your vocabulary:
Cano and Borucki [ 26 ] revived a bacterial spore from the abdominal contents of extinct bees preserved for 25 to 40 million years in buried Dominican amber and cultured and identified it.
As a second measure of aberrant segregation, we determined the frequency of diploid spore colonies in the mutants.
Since S. pombe contains only three chromosome pairs, aberrant assortment during one or both of the meiotic divisions can produce, by chance, a significant fraction of meiotic products that receive at least one copy of each chromosome and are hence viable [ 38 43 ] . Aberrant segregation can also produce nullisomic aneuploids (missing one or more chromosomes), polysomic aneuploids (having additional copies of individual chromosomes), and diploids [ 38 39 44 ] . In S. pombe the haploids and diploids are viable, nullisomic aneuploids are inviable, and disomic aneuploids tend to lose the extra chromosome or chromosomes and become haploid [ 45 ] . We therefore determined the frequencies of spore viability and meiotic diploidy as genetic measures of chromosome segregation errors.
It has been suggested previously [ 38 ] that these phenotypes are characteristic of a defect in meiosis II because spore formation in S. pombe is controlled by the spindle pole body of the MII spindle [ 40 41 42 ] .
An earlier report demonstrated that disruption of HNT2 was tolerated by haploid yeast strains without an effect on growth and that ApppN and AppppN accumulate 30 and 3-fold, respectively on account of the hnt2 deletion [ 13 ] . Because those data were obtained by random spore analysis, we considered it important to test whether elevated dinucleoside polyphosphate levels co-segregate with hnt2 disruption in all tetrads examined and whether any other commonly used genetic markers affect dinucleoside polyphosphate levels.
