- Open AccessGenetic Screening Identifies Cyanogenesis-Deficient Mutants of Lotus japonicus and Reveals Enzymatic Specificity in Hydroxynitrile Glucoside MetabolismAdam Takos, Daniela Lai, Lisbeth Mikkelsen, Maher Abou Hachem, Dale Shelton, Mohammed Saddik Motawia, Carl Erik Olsen, Trevor L. Wang, Cathie Martin, Fred RookPlant 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.

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.

In arbuscular mycorrhizal (AM) symbiosis, development of arbuscules, the structures responsible for mineral nutrient transfer to the plant, requires host plant functions. This work identifies two half-ABC transporters that are widely conserved in the vascular plants. Their interaction and function in the peri-arbuscular membrane is required for arbuscule development and a functional AM symbiosis.
