“…The third group of microorganisms that can be found in the rhizosphere are true and phate (Ca 5 HO 13 P 3 ). Phosphate (P)-solubilizing bacter ia can exert a positive eff ect on tomato growth, increasing the phosphorus status (Van Veen et al, 1997) and signifi cantly enhance photochemical activity accompanied by an increase of chlorophyll content in plants (Liu et al, 2017).…”

SummaryThis study aims to develop a biocontrol agent against Fusarium oxysporum f.sp. radicis-lycopersici (FORL) in tomato. For this, a set of 23 bacterial endophytic isolates has been screened for their ability to inhibit in vitro the growth of FORL using the dual plate assay. Three isolates with the most sound antagonistic activity to FORL have been qualitatively screened for siderophore production, phosphates solubilization and indolic acetic acid (IAA) synthesis as growth promotion traits. Antagonistic values of the three candidates against FORL were respectively: 51.51 % (EB4B), 51.18 % (EB22K) and 41.40 % (EB2A). Based on 16S rRNA gene sequence analysis, the isolates EB4B and EB22K were closely related to Enterobacter ludwigii EN-119, while the strain EB2A has been assigned to Leclercia adecarboxylata NBRC 102595. The promotion of tomato growth has been assessed in vitro using the strains EB2A, EB4B and EB22K in presence of the phytopathogen FORL. The treatments with the selected isolates increased significantly the root length and dry weight. Best results were observed in isolate EB4B in terms of growth promotion in the absence of FORL, improving 326.60 % of the root length and 142.70 % of plant dry weight if compared with untreated controls. In the presence of FORL, the strain EB4B improved both root length (180.81 %) and plant dry weight (202.15 %). These results encourage further characterization of the observed beneficial effect of Enterobacter sp. EB4B for a possible use as biofertilizer and biocontrol agent against FORL.

“…Instead the decline in ETR and ΦPSII under water stress can be attributed to an increase in the reduced plastoquinone pool, which can lead to a decrease in photochemical quenching (Maxwell and Johnson 2000). Although it has been found that NPQ can rise under water stress (Tezara et al 1999, Liu et al 2017, that effect was not found in this study, which suggests that the water stress applied was severe enough as to induce partial stomatal closure, but at the same time not too strong to increase significantly the loss of energy as heat, perhaps because the plants were grown at a mild light intensity [200 µmol(photon) m -2 s -1 ].…”

“…Nonphotochemical quenching (NPQ), an indicator of the thylakoid transmembrane pH gradient, triggers enzymatic and nonenzymatic (physicochemical) reactions that lead to the dissipation of excess excitation energy as heat (Maxwell andJohnson 2000, Papageorgiou andGovindjee 2014). Therefore, NPQ is a mechanism to avoid photooxidative damage and it increases with progressive stress (Tezara et al 1999, Liu et al 2017.…”

Climate models predict an increase in atmospheric CO2 concentration and prolonged droughts in some parts of the Amazon, but the effect of elevated CO2 is still unknown. Two experiments (ambient CO2 -400 ppm and elevated CO2 -700 ppm) were conducted to assess the effect of drought (soil at 50% field capacity) on physiological parameters of Carapa. At ambient CO2 concentration, light-saturated net photosynthetic rate (PNsat) was reduced by 33.5% and stomatal conductance (gs) by 46.4% under drought, but the effect of drought on PNsat and gs was nullified at elevated CO2. Total plant biomass and leaf area production were also reduced (42-47%) by drought. By changing leaf traits, Carapa is able to endure drought, as the consumptive use of water was reduced under drought (32-40%). The improvement of PNsat under elevated CO2 and water stress and the leaf plasticity of Carapa broaden our understanding of the physiology of Amazonian trees.Additional key words: chlorophyll fluorescence; leaf water potential; nonphotochemical quenching; water-use efficiency. use of water; ETRelectron transport rate; FC -field capacity; Fm -maximal fluorescence yield of the dark-adapted state; Fm' -maximal fluorescence yield of the light-adapted state; Fs -steady-state fluorescence yield; Fv/Fm -maximal quantum yield of PSII photochemistry; Fv -variable fluorescence; gs -stomatal conductance; Jmax -maximum electron transport rate; F0 -minimal fluorescence yield of the dark-adapted state; Jmax25 -Jmax at 25°C; LMA -leaf mass per area ratio; NPQ -nonphotochemical quenching; T -temperature in Kelvin; PN -net photosynthetic rate; PNsat -light-saturated PN; PNmax -light-and CO2-saturated PN; RH -relative humidity; TNC -total non-structural carbohydrates; Vcmax -maximum carboxylation rate of Rubisco; Vcmax25 -Vcmax at 25°C; VPDL -leaf-to-air vapor pressure difference; WT -total dry matter (biomass); WUEi -intrinsic water-use efficiency; Γ -CO2-compensation point; Γ* -Γ in absence of mitochondrial respiration; ΨL -leaf water potential; ФPSII -effective quantum yield of PSII photochemistry.

“…Maize growers can maximize leaf area and the net photosynthetic rate to attain high grain yields by properly managing P fertilization (Zhang et al 2018). Managing P fertilization also increases photosynthetic carbon and nitrogen metabolism, as well as water-use efficiency of dwarf bamboo under drought stress (Liu et al 2015(Liu et al , 2017b. Based on the effect of phosphate fertilizer on the photosynthetic performance of plants in a stressful environment, we speculated that phosphate fertilizer could promote soybean photosynthesis in a shaded environment.…”
