Fission rate yeast

Estimation of the fission rate in yeast S. cerevisiae.

1) From paper

http://www.ncbi.nlm.nih.gov/pubmed/9243504 (Table 2),

, the number of fission events per minute per yeast cell, looking at 75% of the cytoplasmic volume, is 0.39 +- 0.14 (stdev). This means that in the entire cell, there are (0.39 +- 0.14)/0.75 fission events per minute.

2) The number of mitochondria in a yeast cell is in the range 20-50 (bionumbers 103070 gives a range 20-30, and paper http://www.ucl.ac.uk/zebrafish-group/publications/jensen2000.pdf gives a range 30-50, which we can interpret as a range from (20,50) (approximately). So let's say a yeast cell has 20-50 mitochondria.

Then the fission rate per mitochondrion is given by 0.016 += 0.007 events per minute per mitochodnrion (Caladis calculation www.caladis.org/compute/?q=%24a%2F(0.75*%24b)&v=a%3Anorm%2C0.39%2C0.14%3Bb%3Aunif%2C20%2C50&x=off&n=m&h=fd&a=rad&_=1430230022022

Estimation of the fusion rate in yeast S. cerevisiae.

This estimation is exactly the same, with the only difference that now the number of fusion events per minute per yeast cell as observed in paper

http://www.ncbi.nlm.nih.gov/pubmed/9243504 (Table 2),

is 0.40 +- 0.008 (stdev). The fusion rate per mitochondrion per minute is now 0.016 +- 0.006 (stdev), Caladis calculation
