“…In addition, 12/13 CO 2 fractionation occurs during diffusion into the cell 50 , 51 . Phosphorus starvation in plants often leads to a disruption of hydraulic conductance due to stomata closure 52 – 54 . Indeed, when the stomata are closed, plants use the CO 2 which is already present in the leave cells and therefore it is very likely that Rubisco can consume also more 13 C as substrate.…”

Plant roots are able to exude vast amounts of metabolites into the rhizosphere in response to phosphorus (P) deficiency. Causing noteworthy costs in terms of energy and carbon (C) for the plants. Therefore, it is suggested that exudates reacquisition by roots could represent an energy saving strategy of plants. This study aimed at investigating the effect of P deficiency on the ability of hydroponically grown tomato plants to re-acquire specific compounds generally present in root exudates by using 13C-labelled molecules. Results showed that P deficient tomato plants were able to take up citrate (+ 37%) and malate (+ 37%), particularly when compared to controls. While glycine (+ 42%) and fructose (+ 49%) uptake was enhanced in P shortage, glucose acquisition was not affected by the nutritional status. Unexpectedly, results also showed that P deficiency leads to a 13C enrichment in both tomato roots and shoots over time (shoots—+ 2.66‰, roots—+ 2.64‰, compared to control plants), probably due to stomata closure triggered by P deficiency. These findings highlight that tomato plants are able to take up a wide range of metabolites belonging to root exudates, thus maximizing C trade off. This trait is particularly evident when plants grew in P deficiency.

“…They stated that Pseudomonas and Rhizobium, Klebsiella and Pseudomonas possess the ability to solubilize insoluble inorganic phosphates and make them available to the plants. P deficiency has a significant influence on leaf photosynthesis and carbon metabolisms in plants (Rao 1996) and could result in smaller size of stomatal opening (Sarker et al 2010). Furthermore, Khan et al (2010) mentioned that phosphorus plays an important role in photosynthesis, energy transfer, signal transduction, and respiration in the plant.…”

“…The photosynthetic rate of plants could be affected by a non-stomatal factor that primarily depends on the activity of intrinsic enzymes, photosynthetic apparatus, and their regulation mechanisms (Li et al, [ 2006 ]). P deficiency could result in smaller in size of stomatal opening (Sarker et al, [ 2010 ]), atmospheric CO 2 became hard to entry into cell of plant, but through catalysis of CA in P. nil , which showed high activity, another carbon source could be supplied for photosynthesis of P. nil by the transformation from HCO 3 − to CO 2 under P deficiency stress. Photosynthesis efficiency can be described by the maximal PSII photochemical efficiency (Fv/Fm) and actual photochemical quantum efficiency of open PSII (Φ PSII ).…”

BackgroundP deficiency in karst areas significantly influenced leaf photosynthesis and carbon metabolisms in plants which were bad for plant growth. Meanwhile, fertilizer application would cause lots of environmental problems. Therefore planning and developing P deficiency-resistant plants in karst areas are important to prevent shortage of P resources and reduce the environmental impacts of P supplementation.ResultsThis study examined the photosynthetic response of three climber plant species, namely, Pharbitis nil (Linn.) Choisy, Lonicera pampaninii Levl, and Parthenocissus tricuspidata (Sieb.et Zucc.) Planch to phosphorus (P) deficiency stress. The plants were exposed to P deficiency stress at three treatments of 0.125 mM, 0.031 mM, and 0 mM for 30 d; 0.250 mM P was used as the control. Photosynthetic responses were determined by measurement of leaf photosynthesis, chlorophyll fluorescence, carbonic anhydrase activity, and stable carbon isotope ratios. Pharbitis nil showed high CA activity, more negative δ13C values and could maintain long-term stable photosynthetic capacity. Lonicera pampaninii also showed high CA activity but positive δ13C values compared to Pharbitis nil, and its photosynthetic capacity decreased as P deficiency stress increased. Parthenocissus tricuspidata had a low photosynthesis and positive δ13C values compared to Pharbitis nil, it could grow normally even under 0 mM P.ConclusionsPharbitis nil was tolerant to long-term, severe P deficiency stress, a finding that is attributed to its stable PSII and regulation of carbonic anhydrase. Lonicera pampaninii showed a poor adaptability to short-term P deficiency, but exhibited long-term tolerance under 0.125 mM P concentration. Parthenocissus tricuspidata was tolerant to long-term P deficiency stress, may exhibit a stomatal limitation. Besides, P deficiency stress had little effect on the way of inorganic carbon utilization of the three climber plants. Different adaptation mechanisms to P deficiency stress should be considered for the selection of species when developing P deficiency-resistant plants.Electronic supplementary materialThe online version of this article (doi:10.1186/s40529-014-0060-8) contains supplementary material, which is available to authorized users.
