Siderophore-Producing Rhizobacteria as a Promising Tool for Empowering Plants to Cope with Iron Limitation in Saline Soils:A Review

引用

Pedosphere 2019年第4期29卷 409-420页

作者： Maria J.FERREIRA Helena SILVA Angela CUNHA Biology Department and Centre for Environmental and Marine Studies(CESAM) University of Aveiro Campus de Santigo

Iron(Fe) bioavailability to plants is reduced in saline soils;however, the exact mechanisms underlying this effect are not yet completely understood. Siderophore-expressing rhizobacteria may represent a promising alternative to chemical fertilizers by simultaneously tackling salt-stress effects and Fe limitation in saline soils. In addition to draught, plants growing in arid soils face two other major challenges: high salinity and Fe deficiency. Salinity attenuates growth, affects plant physiology, and causes nutrient imbalance,which is, in fact, one of the major consequences of saline stress. Iron is a micronutrient essential for plant development, and it is required by several metalloenzymes involved in photosynthesis and respiration. Iron deficiency is associated with chlorosis and low crop productivity. The role of microbial siderophores in Fe supply to plants and the effect of plant growth-promoting rhizobacteria(PGPR) on the mitigation of saline stress in crop culture are well documented. However, the dual effect of siderophore-producing PGPR, both on salt stress and Fe limitation, is still poorly explored. This review provides a critical overview of the combined effects of Fe limitation and soil salinization as challenges to modern agriculture and intends to summarize some indirect evidence that argues in favour of siderophore-producing PGPR as biofertilization agents in salinized soils. Recent developments and future perspectives on the use of PGPR are discussed as clues to sustainable agricultural practices in the context of present and future climate change scenarios.

Pine-fruit shell (PFS) is a lignocellulosic residue derived from the fruit of Araucaria angustifolia, a coniferoustree native of South America, part of a whole vegetation of the Atlantic Forest, found in the South and Southwestof Brazil. In this work PFS will be characterized and used in the production of PFS-based polyols throughoxypropylation. Three series were chosen (PFS/propylene oxide (PO) (w/v, g/mL) of 30/70, 20/80 and 10/90)with four catalyst levels (5%, 10%, 15% and 20%, (w/w, PFS based)). Oxypropylation occurred at moderateconditions of temperature, pressure and time giving rise to liquid polyols with a homopolymer content (PPO)ranging from 4-65%, a hydroxyl number (IOH) between 257-605 mg KOH/g and viscosities (V) varying from0.76 Pa.s to 373.90 Pa.s (20°C) for the series 20/80 and 10/90, while for the series 30/70, the viscosity reachedvalues higher than 500 Pa.s, 20°C. The unreacted PFS (UR) varied between 3.6% and 77.4% (PFS-basis). Afterthe PFS-based polyols production and characterization, a principal component analysis (PCA) was performed inorder to evaluate the established interactions between the used formulation variables and the obtained polyolproperties. The PCA analysis allowed to clarify the interactions between PFS and PO contents and the finalbiopolyol properties (PPO, IOH, V and UR). This approach showed to be a simple method to rationally analyzethe influence of the input formulation variables on the final polyol properties.

Chronic hemodynamic adaptations induced by resistance training with and without blood flow restriction in adults:A systematic review and meta-analysis

Sports Medicine and Health Science 2023年第4期5卷 259-268页

The purposes of this systematic review and meta-analysis of peer-reviewed literature were to examine the chronic effects of resistance training with blood flow restriction(RT-BFR)on hemodynamics,and to compare these adaptations to those induced by traditional resistance training(TRT)programs in adults(PROSPERO:Registry:CRD42022339510).A literature search was conducted across PubMed,Sports Discus,Scielo,and Web of Science *** independent reviewers extracted study characteristics and blood pressure *** of bias(The Cochrane risk of bias tool for randomized controlled trials[RoB-2]),and the certainty of the evidence(Grading of Recommendations,Assessment,Development,and Evaluation[GRADE])were used.A total of eight studies met the inclusion criteria for systolic(SBP),diastolic(DBP),and mean arterial pressure(MAP).Regarding the comparison of RT-BFR ***-exercise,no significant differences favoring the exercise group were observed(p>0.05).However,when compared to TRT,RT-BFR elicited additional improvements on DBP(-3.35;95%CI-6.00 to-0.71;I^(2)=14%;z=-2.48,p=0.01),and on MAP(-3.96;95%CI-7.94 to 0.02;I^(2)=43%;z=-1.95,p=0.05).Results indicate that RT-BFR may elicit a decrease in DBP in comparison with TRT,but the lack of data addressing this topic makes any conclusion *** research on this topic is warranted.
