Area of Science:

  • Microbiology
  • Systems Biology
  • Bioinformatics

Background:

  • High-throughput reverse genetics in microorganisms relies on quantitative readouts for gene function elucidation.
  • Current methods for quantifying microbial phenotypes are limited, primarily focusing on growth and a small number of model organisms.

Purpose of the Study:

  • To develop an image analysis software, Iris, for systematic exploration of microbial phenotypes beyond growth.
  • To enable sensitive and versatile quantification of various cellular processes in diverse microorganisms.

Main Methods:

  • Development of Iris, an image analysis software for quantifying phenotypes like biofilm formation, colony morphogenesis, and reporter activity.
  • Application of Iris to reanalyze existing chemical genomics data in Escherichia coli.
  • Proof-of-principle screens using Iris on biofilm formation and morphogenesis in bacteria and Candida albicans.

Main Results:

  • Iris provides more sensitive growth measurements compared to existing software.
  • Iris successfully recapitulated known genetic insights and identified novel genes and pathways.
  • The software demonstrated compatibility with various microorganisms and data types (endpoint/kinetic).

Conclusions:

  • Iris significantly advances the systematic analysis of microbial macroscopic phenotypes beyond simple growth.
  • The software facilitates the discovery of novel genes and pathways involved in complex cellular processes.
  • Iris is a versatile tool applicable to a broad range of microorganisms and research questions in microbial genetics and systems biology.
