Abstract EN
Rubredoxins are a class of iron-containing proteins that play an important role in the reduction of superoxide in some anaerobic bacteria and also act as electron carriers in many biochemical processes.
Unlike the more widely studied about rubredoxin proteins in anaerobic bacteria, very few researches about the function of rubredoxins have been proceeded in plants.
Previous studies indicated that rubredoxins in A.
thaliana may play a critical role in responding to oxidative stress.
In order to identify more rubredoxins in plants that maybe have similar functions as the rubredoxin-like protein of A.
thaliana, we identified and analyzed plant rubredoxin proteins using bioinformatics-based methods.
Totally, 66 candidate rubredoxin proteins were identified based on public databases, exhibiting lengths of 187–360 amino acids with molecular weights of 19.856–37.117 kDa.
The results of subcellular localization showed that these candidate rubredoxins were localized to the chloroplast, which might be consistent with the fact that rubredoxins were predominantly expressed in leaves.
Analyses of conserved motifs indicated that these candidate rubredoxins contained rubredoxin and PDZ domains.
The expression patterns of rubredoxins in glycophyte and halophytic plant under salt/drought stress revealed that rubredoxin is one of the important stress response proteins.
Finally, the coexpression network of rubredoxin in Arabidopsis thaliana under abiotic was extracted from ATTED-II to explore the function and regulation relationship of rubredoxin in Arabidopsis thaliana.
Our results showed that putative rubredoxin proteins containing PDZ and rubredoxin domains, localized to the chloroplast, may act with other proteins in chloroplast to responses to abiotic stress in higher plants.
These findings might provide value inference to promote the development of plant tolerance to some abiotic stresses and other economically important crops.
