  1. Physiological Bases and a Novel Genetic Determinant of Water-Use Efficiency (WUE)

    Yin, Jie

    <p>Water-use efficiency (WUE), the ratio of biomass to water loss, is a heritable but complex trait, the genetic basis of which is largely unknown. We utilized diverse accessions of the halophyte <em>Eutrema salsugineum </em>to ultimately identify a novel genetic determinant of WUE. <em>E. …
