Grass pea (Lathyrus sativus L.), a legume crop in arid and semi-arid areas, is widely acknowledged as highly drought tolerant. We report here an analysis of grass pea and garden pea seedlings stressed with 20% polyethylene glycol 6000 (PEG) for five days. While leaf margins of grass pea curled inward after PEG stress, leaves of pea failed to display this trait. PEG inhibited the growth of grass pea less than that of pea. Hydrogen peroxide (H2O2) and malondialdehyde (MDA) accumulation increased in pea more than in grass pea. Greater accumulation of proline and soluble sugars alleviated osmotic stress injury to grass pea compared with pea. Moreover, PEG caused a significantly greater increase of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) and glutathione peroxidase (GPX) activities in grass pea compared to pea. These enzymes showed obvious up-regulation at the transcriptional level in grass pea leaves. Together, these data suggest that the accumulation of osmoprotectants and the improvement of oxidation resistance resulted in the higher drought tolerance of grass pea compared to pea.

“…Generally, β-ODAP in plants is hypothesized to function as a carrier molecule for zinc ions [28], a scavenger for hydroxyl ions [29], and as a protector of photosynthesis at high light intensity [30]. Some studies suggest that β-ODAP also plays a role in drought tolerance and in resistance to oxidative stress [31,32]. Currently, our knowledge on the biological role of this important metabolite is far from complete.…”

“…If CAS plays a similar role in grass pea, then changes in CAS might affect the formation of root nodules [16]. Interestingly, it was reported that the five-day-old seedlings of L. sativus inoculated with Rhizobium contained lower levels of β-ODAP than the controls, and that nitrogen deficiency caused the highest accumulation of β-ODAP in the seedlings [10,32]. Studies have shown that CS plays an important role in linking sulfur and nitrogen assimilatory pathways and regulating the flux between these two pathways [59,60].…”

“…In fact, ROS play important roles in the responses of plants to biotic and abiotic environmental stimuli, such as nutrient deficiency, drought, salinity, cadmium, and Rhizobium infection [16]. Leaves containing high levels of β-ODAP had low levels of O 2 .− and H 2 O 2 , while leaves with high contents of O 2 .− and H 2 O 2 accumulated little β-ODAP [32]. This result suggested that ROS, especially O 2 .− , may either inhibit the synthesis of β-ODAP or enhance its degradation [16,32].…”

Grass pea (Lathyrus sativus L.) is an important legume crop grown mainly in South Asia and Sub-Saharan Africa. This underutilized legume can withstand harsh environmental conditions including drought and flooding. During drought-induced famines, this protein-rich legume serves as a food source for poor farmers when other crops fail under harsh environmental conditions; however, its use is limited because of the presence of an endogenous neurotoxic nonprotein amino acid β-N-oxalyl-l-α,β-diaminopropionic acid (β-ODAP). Long-term consumption of Lathyrus and β-ODAP is linked to lathyrism, which is a degenerative motor neuron syndrome. Pharmacological studies indicate that nutritional deficiencies in methionine and cysteine may aggravate the neurotoxicity of β-ODAP. The biosynthetic pathway leading to the production of β-ODAP is poorly understood, but is linked to sulfur metabolism. To date, only a limited number of studies have been conducted in grass pea on the sulfur assimilatory enzymes and how these enzymes regulate the biosynthesis of β-ODAP. Here, we review the current knowledge on the role of sulfur metabolism in grass pea and its contribution to β-ODAP biosynthesis. Unraveling the fundamental steps and regulation of β-ODAP biosynthesis in grass pea will be vital for the development of improved varieties of this underutilized legume.
