      Genetic Screening Identifies Cyanogenesis-Deficient Mutants of Lotus japonicus and Reveals Enzymatic Specificity in Hydroxynitrile Glucoside Metabolism
      Adam Takos, Daniela Lai, Lisbeth Mikkelsen, Maher Abou Hachem, Dale Shelton, Mohammed Saddik Motawia, Carl Erik Olsen, Trevor L. Wang, Cathie Martin, Fred Rook
      Plant Cell May 2010, 22 (5) 1605-1619; DOI: https://doi.org/10.1105/tpc.109.073502

      This work describes a high-throughput screen for mutants affected in their ability to release hydrogen cyanide using the model legume Lotus japonicus. Mutants revealed unexpected specificity in the enzymes of both synthesis and degradation of cyanogenic glucosides and closely related compounds. This may offer flexibility in the production of deterrents to herbivores by this species.

      The Arabidopsis Nitrate Transporter NRT1.8 Functions in Nitrate Removal from the Xylem Sap and Mediates Cadmium Tolerance
      Jian-Yong Li, Yan-Lei Fu, Sharon M. Pike, Juan Bao, Wang Tian, Yu Zhang, Chun-Zhu Chen, Yi Zhang, Hong-Mei Li, Jing Huang, Le-Gong Li, Julian I. Schroeder, Walter Gassmann, Ji-Ming Gong
      Plant Cell May 2010, 22 (5) 1633-1646; DOI: https://doi.org/10.1105/tpc.110.075242

      Environmental stresses affect the nitrate distribution between roots and shoots, and transporters that remove nitrate from the xylem sap are essential for long-distance nitrate transport. This study shows that the nitrate transporter NRT1.8 is induced by cadmium and removes nitrate from xylem vessels and furthermore establishes a correlation between nitrate allocation and cadmium tolerance.
