“…Grasspea seeds contain about 8.6–34.6%, protein content which is higher than chickpea (18%), field pea (21%), French bean (20%) ( 41 ). Grasspea seeds consist of around 60% globulins and 30% albumins in the total seed proteins with 90% digestibility at a 10% level of protein intake ( 42 – 46 ). Analysis of seeds for carbohydrates and crude fiber has shown that these vary between 48–52.3% and 1.1–1.7%, respectively ( 9 , 27 , 44 ).…”

“…The iron and zinc content in grasspea seeds ranged 6.9–8.7 mg/100 g and 2.46–36.7 mg/100 g, respectively ( 58 , 59 ). However, large genetic variability for iron and zinc concentration in Lathyrus genetic resources were observed at ICARDA breeding programme ( 46 , 67 ) that can be used for biofortification or genetic improvement of grasspea. The comparative table on nutritive value of grasspea with other cool season legumes are given in the Table 3 .…”

The genus Lathyrus consists of more than 184 herbaceous annual and perennial species suitable for multifaceted sustainable food and feed production system in the arid and semi-arid regions of the world. The grasspea is a promising source of protein nutrition. However, its potential is not being utilized fully due to the presence of neurotoxin content (β-N-oxalyl-l-α, β diaminopropionic acid, β-ODAP), a causal agent of non-reversible lower limbs paralysis. The high protein contents in seeds and leaves with ~90% digestibility make it sustainable super food to beat protein malnutrition in future. Therefore, it is desired to breed new grasspea cultivars with low β-ODAP contents. Limited research has been carried out to date about this feature. A draft genome sequence of grasspea has been recently published that is expected to play a vital role in breeding and identifying the genes responsible for biosynthesis pathway of β-ODAP contents in grasspea. Efforts to increase awareness about the importance of genus Lathyrus and detoxify β-ODAP in grasspea are desired and are in progress. Presently, in South Asia, systematic and dedicated efforts to support the farmers in the grasspea growing regions by disseminating low β-ODAP varieties has resulted in a considerable improvement in reducing the incidence of neurolathyrism. It is expected that the situation will improve further by mainstreaming grasspea cultivation by implementing different approaches such as the development and use of low β-ODAP varieties, strengthening government policies and improved detox methods. The present review provides insight into the multifaceted characteristics of sustainable nutritious grasspea in the global and Indian perspective.

“…Some of these breeding programmes are still active, however, they are meager in comparison with that for other legume crops (Vaz Patto et al, 2006 ). Several varieties and lines have been developed by combining low β-ODAP (<0.1%) with high-yield potential (up to 1.5 tons/ha) and resistance to an array of biotic and abiotic stresses (Kumar et al, 2013 ; Dixit et al, 2016 ; Sen Gupta et al, 2021 ).…”

Grass pea is well-established as one of the most resilient and versatile crops that can thrive under extreme climatic circumstances such as cold, heat, drought, salt-affected soils, submergence, and excessive rainfall along with resistance to several diseases and pests. However, despite the awareness of its virtues, its cultivation globally has decreased recently owing to the presence of a neurotoxin, β-N-oxalyl-L-α, β-diaminopropionic acid (β-ODAP), in the seedlings and seeds of this legume, which has been reported to cause neurolathyrism, a non-reversible neurological disorder in humans and animals. Significant repositories of Lathyrus germplasm are available across countries that have provided access to a wide range of agro-morphological traits as well as the low β ODAP content. Efforts have been made worldwide to use these germplasms for the genetic enhancement of grass pea to make this food safe for human consumption. Efforts on molecular breeding of this crop are also lagging. However, during the last decade, the research scenario has changed with some efforts being made toward improving this climate resilient pulse in terms of genomic resources. Molecular markers have also been used to evaluate the interspecific diversity as well as the phylogenetic relationship among the species and mapping studies. Intron-targeted amplified polymorphic, genomic simple sequence repeat, resistance genes analogs, and disease resistance markers developed for other legume species have been successfully cross-amplified in grass pea. Transcriptomic studies have recently been undertaken on grass pea by deploying several second-generation sequencing techniques. In addition, a few studies have attempted to unveil the genes and the underlying mechanism conferring biotic and abiotic stress or regulating the pathway of β-ODAP in grass pea. Proteomics has accelerated the identification studies on differential proteomes in response to salinity and low-temperature stress conditions for unveiling the common signaling pathways involved in mitigating these abiotic stresses and in discovering differentially regulated proteins. In grass pea, a metabolomics approach has been used to identify the metabolic processes associated with β-ODAP synthesis. Genome sequencing of grass pea is under way which is expected to be vital for whole-genome re-sequencing and gene annotation toward the identification of genes with novel functions. Recently, a draft genome sequence of grass pea was developed, and some efforts are underway to re-sequence a diverse panel of grass pea comprising 384 germplasm lines. Owing to the scantiness of a successful transformation protocol, research on the application of modern approaches of genome editing like the Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) or CRISPR-associated protein 9 (CRISPR/Cas9) system for the engineering of signaling pathways or regulatory mechanisms seeks immediate attention to reduce the β-ODAP content in seeds and to improve the potential agronomic traits in grass pea.

“…In the recent past, the crop has received considerable attention from scientific and farming community alike due to its climate smart attributes such as tolerance to drought, waterlogging, heat, cold, and salinity (Lambein et al, 2019). Grass pea is recognized as a source of affordable protein, micronutrients, and fiber of seeds (Sen Gupta et al, 2021;Tamburino et al, 2012;Tarade et al, 2007). Although grass pea is rich in protein, its utilization is limited by the presence of a free non-protein amino acid, called β-N-Oxalyl-L-α, βdiaminopropionic acid (β-ODAP).…”

Grass pea (Lathyrus sativus L.) is an important food legume crop but notorious for plant neurotoxin β-N-Oxalyl-L-α, β-diaminopropionic acid (β-ODAP), causing neurolathyrism to human and animals. The study aimed to compare changes in physical and chemical parameters of 13 genotypes of different geographic origins in pre & post-boiling, microwaving and autoclaving. The results showed significantly different effects of pre and post-cooking treatments on genotypes and cooking methods independent of one another. The genotypes from South Asia exhibited higher β-ODAP content compared to the genotypes from other region. Significantly negative correlation was noted between protein content and β-ODAP concentration across the treatments under boiling (r = −0.555**) and microwave (r = −0.342*) treatments. Boiling was the best treatment and significantly reduced β-ODAP concentration by 70%. Its reduction percentage remained 30%, and 14% under microwaving and autoclaving, in the same order. Therefore, boiling was recommended over other treatments for safe human consumption of grass pea seeds.
