Transcriptome analysis of cyst formation in Rhodospirillum centenum reveals large global changes in expression during cyst development.

ABSTRACT:

Background

Rhodospirillum centenum is a photosynthetic member of the Gram-negative Azospirillum clade members of which exhibit a complex developmental life-cycle featuring morphologically distinct cell types. Under periods of nutrient deprivation, replicative vegetative cells differentiate into metabolically dormant cysts that survive harsh environmental stresses such as desiccation. Encystment involves a multi-stage developmental process that includes the rounding of cells, production of large intracellular storage granules of poly-hydroxybutyrate (PHB) and the excretion of a protective exopolysaccharide coating that envelops dormant cysts.

Results

To study the process of cyst development, we performed RNA-seq studies on cells that were induced to undergo cyst development.
