Phosphate-limitation physiology in ectomycorrhizal pitch pine
H2PO4 (Pi) uptake rates, and root surface acid phosphatase (APase) rates were assessed in pitch pine (Pinus rigida Mill.) seedlings inoculated with the ectomycorrhizal fungi Laccaria bicolor (Maire) Pat., Paxillus involutus (Batsch.) Fr., or Pisolithus tinctorius (Pers.) Coker and Couch, and grown at 10 or 100 μM Pi in sand culture. Following a 6-week period of acclimation to the Pi regimes, se...
متن کاملInfluence of growth rate on the physiological response of marine Synechococcus to phosphate limitation
Phosphate (P) is an important nutrient potentially limiting for primary productivity, yet, we currently know little about the relationship between growth rate and physiological response to P limitation in abundant marine Cyanobacteria. Thus, the aim of this research was to determine how variation in growth rate affected the physiology of marine Synechococcus WH8102 and CC9311 when growing under...
متن کاملPhoB Activates Escherichia coli O157:H7 Virulence Factors in Response to Inorganic Phosphate Limitation
Enterohemorrhagic Escherichia coli (EHEC), an emerging food- and water-borne hazard, is highly pathogenic to humans. In the environment, EHEC must survive phosphate (Pi) limitation. The response to such Pi starvation is an induction of the Pho regulon including the Pst system that senses Pi variation. The interplay between the virulence of EHEC, Pho-Pst system and environmental Pi remains unkno...
متن کاملThe transcriptional control of plant responses to phosphate limitation.
Plants have evolved an array of responses that adapt their growth to conditions of limited phosphate (Pi) supply. These involve biochemical and developmental changes that improve Pi acquisition and recycling, and protect against the stress of Pi starvation. The induction of these responses requires a sophisticated regulatory system that integrates information on external and internal plant Pi s...
متن کاملphosphate limitation modulates capsular polysaccharide composition in mycobacteria 4
Inorganic phosphate limitation modulates capsular polysaccharide composition in mycobacteria 4. Running title: Pi limitation modulates capsular polysaccharide composition. ABSTRACT Mycobacterium tuberculosis is protected by an unusual and highly impermeable cell-envelope that is critically important for the successful colonisation of the host. The outermost surface of this cell envelope is form...
