Overview

After a Rank Prize Fund Fellowship on seed germination in Bangor, in 1979, Royal Society and DFG fellowships allowed me to spend 12 months in the Membrane Research Group of the Nuclear Research Centre Jülich, (West) Germany. This seminal experience laid the foundation of a lifelong international career (in Bangor) linking biochemistry and biophysics at the level of the individual cell in situ in a unique way.  By the use of quantitative tissue mapping using microcapillaries (Ann. Rev. Plant Biol. 50:447, 1999), the Bangor SiCSA Lab has played a global role in understanding the fundamental mechanical, water and solute relations at individual cell resolution within plant tissues.  Initially a description of previously unknown basic water relations parameters, this progressed via the mechanics of leaf and root growth (New Phytol 112:1, 1989; Plant Physiol 93:222, 1990) and movement (Bot. Acta 110:118, 1997) to the interplay of individual cell’s osmotic adjustment (Planta 196:40, 1995) and metabolism (New Phytol. 136:97, 1997; Plant Physiol. 124:599, 2000). The lab was one of the first to quantify gene expression in individual cells in situ (Plant Physiology 130:1335, 2002) and one of a very small number to relate metabolism to gene expression. A key discovery has been the key role played by, and the heterogeneity of, the extracellular matrix (apoplast) (J Exp Bot 52:623, 2001; Planta 215: 210, 2002). Despite a reduced output in recent years (I was not included in the latest REF – but had contributed two world class researchers to each of the previous two research exercises) I recently contributed (as the only plant scientist) to two international conferences in the “new” area of Single Cell Analysis (London 2012, Boston, 2014). Equipment designed and built in Bangor has been sold around the world (including to Reken) and researchers from all over the world have come for training to Bangor. This basic science has been applied to a wide range of applications. Much of which has been in the applied context of stress tolerance (from low temperature to anti-tank shell (DU) fragments). A battery of techniques continues to be developed to analyse picolitre samples from cells in situ. The latest include CZE and MALDI-TOF-MS. Previous approaches have included MRI (Cell & Mol. Biol of Wood Formation. Eds Savidge et al; Bios. 101, 2000) and con-focal microscopy (PNAS  97: 1932, 2000. The techniques are also now being applied to the rhizosphere (Plant & Soil 368:471, 2013).  In a different context, the lab was seminal in the major current Bangor rice breeding programme (Theor Appl Genet 95:143, 1997). Since 2009, I have been involved in a series of explicitly commercial-linked programmes (BBSRC-Link and KESS) involving valuable products of plants. The largest involved galanthamine (an anti-Alzheimer drug) synthesis in daffodils. These brought me even closer to individuals within the Bangor School of Chemistry. In 2018 I was working with Prof Bela Paizs adapting the single cell CZE output for Mass Spectroscopy.
