DATA & FILE OVERVIEW

 

1. Description of dataset

In this study, we address whether stochastic phenotypic switching can shape biological diversity contributing to evolutionary change across the transition from single cells to multicellular clutters in Saccharomyces cerevisiae multicellular yeast system. Population's characterization was conducted with a Coulter Counter multisize 4, and a FlowCam 3, by colony morphology, under the optic microscope, via ACE2 gene sequencing and RNA sequencing. The populations studied were the genetically uniform diploid wild-type Saccharomyces cerevisiae Y55 strain clones, C1W8.1 and C1W8.2 multicellular evolved strains, constructed ACE2 gene knockouts, and strains containing the missense mutation (ACE2 c.1934 A>T).

METHODOLOGICAL INFORMATION

Strains: ancestral wildtype (Y55 strains), C1W8.1 and C1W8.2 multicellular derived strains isolated after 60 days of selection in YPD media, constructed ACE2 gene knockouts, and strains containing the ACE2 missense mutation (ACE2 c.1934 A>T).

Media: Growth media used in this study were Yeast Peptone Dextrose media (YPD; 1% (v/w) yeast extract, 2% (v/w) peptone, 2% (v/w) D-glucose, pH 5.8) and Standard minimal (SD; Yeast nitrogen base with amino acids (YNB w/AA) 6.7 g L-1, 0.5% (v/w) D-glucose).

Phenotypic characterization of the different strains was conducted in a Coulter Counter Multisizer 4 and FlowCam® 3.0 Fluid Imaging Technologies, colony morphology, and optic microscopy. Replicate populations of different individual isolates per strain were analyzed to obtain the population distributions in YPD media.

RNA was extracted using an Invitrogen® PureLink RNA Mini Kit. Three of four extracted samples per treatment with the highest RNA integrity score were submitted for TrueSeq Stranded RNA-Seq.
