Figure 1From: Transcriptome analysis of cyst formation in Rhodospirillum centenum reveals large global changes in expression during cyst development Phase-contrast microscopy depicting representative stages in R. centenum cyst formation. The panels labeled with black numbers show demonstrative cell types observed at 4Â h, 24Â h, 48Â h, 72Â h and 96Â h time points after induction of cyst formation by a shift from CENS (0Â h) to CENBA medium.Back to article page
