Genotypic Variation in the Concentration of β-N-Oxalyl-L-α,β-diaminopropionic Acid (β-ODAP) in Grass Pea (Lathyrus sativus L.) Seeds Is Associated with an Accumulation of Leaf and Pod β-ODAP during Vegetative and Reproductive Stages at Three Levels of Water Stress.

Abstract excerpt

Grass pea (Lathyrus sativus L.) cultivation is limited because of the presence in seeds and tissues of the nonprotein amino acid β-N-oxalyl-L-α,β-diaminopropionic acid (β-ODAP), a neurotoxin that can cause lathyrism in humans. Seven grass pea genotypes differing in seed β-ODAP concentration were grown in pots at three levels of water availability to follow changes in the concentration and amount of β-ODAP in...
