    1. Accumulation of sugars in the xylem apoplast observed under water stress conditions is controlled by xylem pH.

      The xylem of poplar trees was shown to respond to embolism formation by accumulating soluble carbohydrates in the apoplast and dropping xylem sap pH. Our analysis suggests that there is a functional link between these two processes. Real time, in vivo measurements showed a sudden drop in the pH of the xylem apoplast in the range of stem water potentials responsible for severe levels of embolism. The restoration of higher pH followed recovery from stress. Measurements also showed that the observed range of changes in pH may influence the dynamics of sugar accumulation in xylem sap. We propose a new model of stem ‘priming’ for stress recovery that is triggered by lowering pH of the xylem and the activation of xylem invertase.

      Summary

      Perennial grasses have been identified as being, in many ways, ideal feedstocks for bioenergy production. Yet side-by-side comparisons of key carbon fluxes and pools, particularly in response to climate extremes, for perennial grasses compared with the traditional row crops that they replace are needed. This research represents a long-term eddy covariance experiment, encompassing a severe drought, where three perennial ecosystem are compared with traditional row crops. The results show that perennial ecosystems are more resilient to drought than row crops both in terms of carbon uptake and storage and that a post-drought effect may be more likely in a perennial relative to annual ecosystem.

    2. Element distribution and iron speciation in mature wheat grains (Triticum aestivum L.) using synchrotron X-ray fluorescence microscopy mapping and XANES imaging

      Accepted manuscript online: 2 APR 2016 01:16AM EST | DOI: 10.1111/pce.12749

      While it is known that much of the iron (Fe) in wheat grains is associated with phytate in the aleurone, little is known about the distribution of Fe species in the other grain tissues (i.e. crease, embryo) and about the local association of Fe with other possible ligands. This paper demonstrates the use of XANES imaging for speciation analysis of an essential element in a staple food grain. Our results show that large differences in element distribution and Fe speciation exist within and between different wheat grain tissues due to the presence of different transport mechanisms. We show that Fe in the nucellar projection is not phytate bound.

    4. Acclimation of the crucifer Eutrema salsugineum to phosphate limitation is associated with constitutively high expression of phosphate-starvation genes

      V.M.E. Velasco, John Mansbridge, Samantha Bremner, Kimberley Carruthers, Peter S. Summers, Wilson W.L. Sung, Marc J. Champigny and Elizabeth A. Weretilnyk

      Accepted manuscript online: 1 APR 2016 09:45PM EST | DOI: 10.1111/pce.12750

      Phosphorus is a limiting macronutrient in many natural habitats and managed agricultural systems. We show that an extremophile crucifer, Eutrema salsugineum (synonymous with Thellungiella salsuginea) copes with low phosphate (Pi) using strategies different than its close relative, Arabidopsis thaliana. Pi-starved seedlings and four-week old plants have reduced Pi content relative to plants fertilized with Pi but otherwise exhibit comparable phenotype and biomass suggesting that Eutrema has a naturally high capacity to acquire and manage Pi efficiently. Our results are consistent with Eutrema plants anticipating low environmental Pi, a behaviour revealed in part by a constitutive expression of genes identified as Pi-starvation responsive in other plants, including Arabidopsis.

    5. Genetic background and environmental conditions drive metabolic variation in wild type and transgenic soybean (Glycine max) seeds

      Hagai Cohen, Ofer M. Shir, Yang Yu, Wensheng Hou, Shi Sun, Tianfu Han and Rachel Amir

      Accepted manuscript online: 1 APR 2016 08:15PM EST | DOI: 10.1111/pce.12748

      Brief Summary Statement

      Wild type and transgenic soybean (Glycine max) seeds with higher methionine contents were grown in four geographical habitats in China characterized by different climatic conditions. Using metabolite profiling and advanced statistical tools we revealed genotype-by-environment interactions, suggesting that mutual relationships existing between the variables of genetic background and environmental conditions are key-determining factors of metabolite profiles in seeds grown under natural environments.
