Table 1 Description of expression profiles obtained by K-means clustering (K = 10) of microarray data

From: Clustering of Pseudomonas aeruginosa transcriptomes from planktonic cultures, developing and mature biofilms reveals distinct expression profiles

Cluster No Up-regulation in:
1 confluent biofilm time points (expression peak – 14 hrs)
2 confluent biofilm time points (expression peak – 48 hrs)
3 confluent biofilm time points and in SP planktonic culture
4 LP planktonic culture (expression peak) and in developing biofilms (8 hrs)
5 LP planktonic culture and in developing biofilms (8 hrs) (expression peak)
6 SP planktonic culture
7 LP planktonic culture,
8 developing biofilms (8 hrs)
9 LP and SP planktonic culture
10 SP planktonic culture and in developing biofilms (8 hrs)
