Significant Contributions to Research Field

    The paradigm that sink processes exert primary control over resource distribution in plants (Patrick 1997) has guided my approach to discovering how nutrient (and water) transport is regulated. In established non-meristimatic sinks, control is restricted to sink transport processes (Patrick 1997). To examine these transport phenomena experimentally, we introduced an innovative model using developing legume seeds (Patrick & McDonald 1980). Thereafter, substantial progress has been made in understanding cellular pathway, mechanism and control of nutrient and water import into seed sinks (Zhang et al., 2007). Employing novel structure/function

    approaches, CE Offler and I showed that nutrient release/uptake occurs in specialised transport cells located at maternal/filial seed interfaces (Patrick and Offler 2001). These studies highlighted a central role for transfer cells in developing seeds (Offler and Patrick 1993). A claim since verified by physiological and molecular observations (Zhang et al., 2007). With NA Walker, we showed that sucrose release from maternal seed tissues was energy

    +coupled by a proton antiport mechanism and that uptake by their filial tissues occurs by sucrose/H symport

    (Patrick 1997). The latter finding was the first direct demonstration of transport function by a higher plant transfer cell (McDonald et al., 1996 cited in Patrick 1997). These findings underpinned a collaboration with W Frommer

    +to clone genes encoding sucrose/ (Tegeder et al., 1999) and amino acid/ (Tegeder et al., 2000) H symporters and

    sucrose effluxers (Zhou et al., 2007a). A molecular genetic approach established that sucrose transporters play a central role in determining biomass accumulation by seeds (Rosche et al., 2002). With SD Tyerman, we

    discovered channels, including novel non-selective channels (Zhang et al., 2004) and aquaporins (Zhou et al.,

    2007b), responsible for release of phloem-imported ions and water respectively from seed coats (Zhang et al.

    2007). We developed a verifiable model that resource transport in maternal and filial seed tissues is regulated by a turgor homeostatic mechanism located in maternal seed tissue (Patrick 1997; Zhang et al., 2007). Working along

    similar lines to those described above, discovering the cellular pathway of phloem unloading in developing tomato fruits (Ruan and Patrick 1995) led to identifying hexose transporters as major determinants of fruit sugar levels (Dibley et al unpubl).
