Other claims from this paper (6)
- Intervention effect Frankia cells exposed to Alnus roots most strongly upregulated the potassium transporter operon kdp and an ABC transporter operon of uncharacterized function.
- Intervention effect Frankia cells exposed to Alnus roots most strongly upregulated acyl dehydrogenases and the potassium transporter Kdp at protein level.
- Observation A cluster of two cellulases and a cellulose synthase among the 60 most upregulated was conserved in Frankia and other actinobacteria such as Streptomyces.
- Observation Cellulase activity was detected on CMC all along the length of the root but not away from it.
- Intervention effect Cellulose synthase was active at the hyphal tip in response to Alnus root exudates, giving a calcofluor stained tip.
- Mechanism The authors suggest the upregulated genes and proteins indicate preadaptation of Frankia to stresses linked to penetration into isotonic host tissues.
