“…Previous studies have reported significant differences in root uptake of mineral nutrients under different root-zone temperatures (Tindall et al 1990;Hood and Mills 1994), suggesting that plant mineral nutrient acquisition is also sensitive to temperature change. Considering the primary contribution of AM fungi in providing mineral nutrients such as phosphorus and trace elements to their host plants (Smith and Read 2008), it is of interest to know whether AM fungi and night warming interactively influence plant nutrient acquisition.…”

Elevated night temperature, one of the main climate warming scenarios, can have profound effects on plant growth and metabolism. However, little attention has been paid to the potential role of mycorrhizal associations in plant responses to night warming, although it is well known that symbiotic fungi can protect host plants against various environmental stresses. In the present study, physiological traits of Medicago truncatula L. in association with the arbuscular mycorrhizal (AM) fungus Rhizophagus irregularis were investigated under simulated night warming. A constant increase in night temperature of 1.53°C significantly reduced plant shoot and root biomass, flower and seed number, leaf sugar concentration, and shoot Zn and root P concentrations. However, the AM association essentially mitigated these negative effects of night warming by improving plant growth, especially through increased root biomass, root to shoot ratio, and shoot Zn and root P concentrations. A significant interaction was observed between R. irregularis inoculation and night warming in influencing both root sucrose concentration and expression of sucrose synthase (SusS) genes, suggesting that AM symbiosis and increased night temperature jointly regulated plant sugar metabolism. Night warming stimulated AM fungal colonization but did not influence arbuscule abundance, symbiosis-related plant or fungal gene expression, or growth of extraradical mycelium, indicating little effect of night warming on the development or functioning of AM symbiosis. These findings highlight the importance of mycorrhizal symbiosis in assisting plant resilience to climate warming.

“…By contrast, plants grown at 22, 28 and 33 C were free of B deficiency at the same level of B supply (Forno et al, 1979). In a less chilling-sensitive species, tomato (Lycopersicon esculentum 'Burpee') (Kratsch and Wise, 2000), reduction in B uptake at 93 mM B only occurred after root temperature was decreased to 10 C (Tindall et al, 1990). However, exposure to 10 C in the root zone did not decrease B uptake in chilling-tolerant species, such as oilseed rape and wheat (Huang et al, 1996;Ye et al, 2003), because this temperature is above their chilling threshold (Macduff et al, 1987).…”

“…In chilling-sensitive species like cassava, sunflower and tomato, root chills decreased B uptake rates, B transport from root to shoot, and B partitioning into young leaves, consequently enhancing the sensitivity of new shoot growth to B deficiency, at low/marginal external B supply (e.g. at 0Á25 mM B in sunflower at 12 C) (Forno et al, 1979;Tindall et al, 1990;Ye et al, 2000). In contrast, low root temperature (10 C) delayed B deficiency in chilling-tolerant species like oilseed rape compared with 20 C in the root zone (Ye et al, 2003), through maintaining root growth and B uptake rate and increasing B partitioning into new shoot growth.…”

“…Root chills decrease B partitioning into new leaves, and thus increase the sensitivity of leaf growth to low B supply (Forno et al, 1979;Tindall et al, 1990;Ye et al, 2000). From the available experimental evidence (Table 1), root chill-induced effects on B transport into, and B partitioning within, the shoot may be regulated by chilling-induced leaf stomatal responses and transpiration, particularly in mature leaves, which are expected to contribute to most of the transpiration activity in the canopy on the basis of their leaf area.…”

Background Field observations and glasshouse studies have suggested links between boron (B)-deficiency and leaf damage induced by low temperature in crop plants, but causal relationships between these two stresses at physiological, biochemical and molecular levels have yet to be explored. Limited evidence at the whole-plant level suggests that chilling temperature in the root zone restricts B uptake capacity and/or B distribution/utilization efficiency in the shoot, but the nature of this interaction depends on chilling tolerance of species concerned, the mode of low temperature treatment (abrupt versus gradual temperature decline) and growth conditions (e.g. photon flux density and relative humidity) that may exacerbate chilling stress.Scope This review explores roles of B nutrition in chilling tolerance of continual root or transient shoot chills in crop species adapted to warm season conditions. It reviews current research on combined effects of chilling temperature (ranging from >0 to 20 C) and B deficiency on growth and B nutrition responses in crop species differing in chilling tolerance.Conclusion For subtropical/tropical species (e.g. cucumber, cassava, sunflower), root chilling at 10-17 C decreases B uptake efficiency and B utilization in the shoot and increases the shoot : root ratio, but chilling-tolerant temperate species (e.g. oilseed rape, wheat) require much lower root chill temperatures (2-5 C) to achieve the same responses. Boron deficiency exacerbates chilling injuries in leaf tissues, particularly under high photon flux density. Suggested mechanisms for B · chilling interactions in plants are: (a) chilling-induced reduction in plasmalemma hydraulic conductivity, membrane fluidity, water channel activity and root pressure, which contribute to the decrease in root hydraulic conductance, water uptake and associated B uptake; (b) chilling-induced stomatal dysfunction affecting B transport from root to shoot and B partitioning in the shoot; and (c) B deficiency induced sensitivity to photo-oxidative damage in leaf cells. However, specific evidence for each of the mechanisms is still lacking. Impacts of B status on chilling tolerance in crop species have important implications for the management of B supply during sensitive stages of growth, such as early growth after planting and early reproductive development, both of which can coincide with the occurrence of chilling temperatures in the field.

“…Assimilate partitioning, taking place via apoplastic and symplastic pathways under high temperature, has significant effects on transport and transfer processes in plants although it strongly depends on genotypes (Yang et al, 2002;Taiz and Zeiger, 2006). Mineral uptake by plants in the rhizosphere is directly influenced by soil temperature, and the lower (chilling) and higher (heat) temperatures compared to the optimum lead to a considerable reduction in mineral uptake (Cumbus and Nye, 1984;Raju et al, 1990;Tindall et al, 1990).…”
