Abstract
This study analyzed the impact of
isiA
deletion on the transcriptomic profile of
Synechocystis
. The
isiA
gene encodes an iron stress-induced chlorophyll-binding protein, which is significantly induced under iron starvation. The deletion of
isiA
affects the expression of various genes that are involved in photosynthesis and ABC transporters. WGCNA revealed three functional modules in which the blue module was correlated with oxidative stress. We further demonstrated that the
isi
operon contained the following five genes:
isiA
,
isiB
,
isiC
,
ssl0461
, and
dfp
by cotranscriptional PCR. Three sRNAs were identified that were related to oxidative stress. This study enhances our knowledge of IsiA-regulatory mechanisms under iron deficiency and oxidative stress.
