    Innovations in industrial and functional food applications of lentil in the era of biofortification
    (Springer Nature Publishing AG, 2025) Padhy, Asish Kumar; Chaurasia, Shiksha; Manivannan, Abinaya; Tripathi, Kuldeep; Sapna, Sapna; Bhatia, Sabhyata
    Lentil can serve as a prebiotic and therapeutic healthy food due to the presence of essential micronutrients, functional proteins, minerals, and carbohydrates, as well as phytochemicals that have shown to be promising in the prevention of several chronic diseases. Nutraceutical properties derived from the phytochemicals present in lentil has expanded its scope of usage to a broader perspective. In this regard, a lot of innovations have been carried out to use lentil in the form of crisps, chips, bakery products, yogurt, pasta, including in the brewing industries. Eforts are being carried out to develop meat analogs out of lentil four. However, niche area specifc consumer preferences have limited its explorations in other innovative areas. This will also necessitate developing genetic resources and varieties aligning to the needs of producers and consumers with acceptable sensory properties. Hence, demand driven development of breeding materials for biofortifcation and crop improvement programs needs considerable amount of investment in research and development of the crop. This review is a campedium of innovations in development of industrial, functional food products from lentil along with their nutritional properties and sensory acceptability serve a foundation for the researchers to invent more to popularize lentil among the consumers to ensure nutritional security.

    Understanding abiotic stress responses in lentil under changing climate regimes
    (Springer Nature Publishing AG, 2023) Singh, Baljinder; Padhy, Asish Kumar; Ambreen, Heena; Yadav, Manisha; Bhardwaj, Shubham; Singh, Gourav; Pandey, Vimal; Chakraborty, Anirban; Bhatia, Sabhyata
    Lentil (Lens culinaris Medik.) is a cool-season grain legume crop that is mainly cultivated across the semi-arid regions of Australia, South Asia, Africa, and North America. The crop is highly valued for its nutritional attributes such as dietary proteins (22–35%), carbohydrates, minerals, and fiber that play a significant role in alleviating malnutrition and micronutrient deficiencies across populations in developing countries. The last five decades have seen an upward trend in global production of lentils from 0.85 to 5.73 Mt. suggesting its increasing demand and utilization. However, various abiotic stresses such as drought, heat, cold, salinity, and nutrient deficiency impose severe threats to the global lentil yield and productivity. The current book chapter is an attempt to comprehend the morpho-physiological and biochemical changes occurring during these stresses and the developmental plasticity shown by the plant to counteract them. Furthermore, the current status of research focusing on the development of novel molecular and functional markers/tags, identification of candidate genes/QTLs responsible for abiotic stress tolerance, the intervention of high throughput genotyping and phenotyping platforms, development of populations and linkage maps, and omics studies have been discussed. Some tolerant germplasm and varieties developed through conventional and next-generation breeding approaches are also enlisted making the book chapter a concise platform for reports of abiotic stress tolerance in lentils.

    Construction of a genetic linkage map and identification of QTLs for seed weight and seed size traits in lentil (Lens culinaris Medik.)
    (PLOS, 2015) Verma, Priyanka; Goyal, Richa; Chahota, R.K.; Sharma, Tilak R.; Abdin, M. Z.; Bhatia, Sabhyata
    Seed weight and seed size both are quantitative traits and have been considered as important components of grain yield, thus identification of quantitative trait loci (QTL) for seed traits in lentil (Lens culinaris) would be beneficial for the improvement of grain yield. Hence the main objective of this study was to identify QTLs for seed traits using an intraspecific mapping population derived from a cross between L. culinaris cv. Precoz (seed weight-5.1g, seed size-5.7mm) and L. culinaris cv. L830 (seed weight-2.2g, seed size-4mm) comprising 126 F8-RILs. For this, two microsatellite genomic libraries enriched for (GA/CT) and (GAA/CTT) motif were constructed which resulted in the development of 501 new genomic SSR markers. Six hundred forty seven SSR markers (including 146 previously published) were screened for parental polymorphism and 219 (33.8%) were found to be polymorphic among the parents. Of these 216 were mapped on seven linkage groups at LOD4.0 spanning 1183.7cM with an average marker density of 5.48cM. Phenotypic data from the RILs was used to identify QTLs for the seed weight and seed size traits by single marker analysis (SMA) followed by composite interval mapping (CIM) which resulted in one QTL each for the 2 traits (qSW and qSS) that were co-localized on LG4 and explained 48.4% and 27.5% of phenotypic variance respectively. The current study would serve as a strong foundation for further validation and fine mapping for utilization in lentil breeding programs.

    Exploring genetic variability within lentil (Lens culinaris Medik.) and across related legumes using a newly developed set of microsatellite markers
    (Springer, 2014) Verma, Priyanka; Sharma, Tilak R.; Srivastava, Prem S.; Abdin, M. Z.; Bhatia, Sabhyata
    Lentil (Lens culinaris Medik.) is an economically important grain legume, yet the genetic and genomic resources remain largely uncharacterized and unexploited in this crop. Microsatellites have become markers of choice for crop improvement applications. Hence, simple sequence repeat (SSR) markers were developed for lentil through the construction of genomic library enriched for GA/CT motifs. As a result 122 functional SSR primer pairs were developed from 151 microsatellite loci and validated in L. culinaris cv. Precoz. Thirty three SSR markers were utilized for the analysis of genetic relationships between cultivated and wild species of Lens and related legumes. A total of 123 alleles were amplified at 33 loci ranging from 2-5 alleles with an average of 3.73 alleles per locus. Polymorphic information content (PIC) for all the loci ranged from 0.13 to 0.99 with an average of 0.66 per locus. Varied levels of cross genera transferability were obtained ranging from 69.70 % across Pisum sativum to 12.12 % across Vigna radiata. The UPGMA based dendrogram was able to establish the uniqueness of each genotype and grouped them into two major clusters clearly resolving the genetic relationships within lentil and related species. The new set of SSR markers reported here were efficient and highly polymorphic and would add to the existing repertoire of lentil SSR markers to be utilized in molecular breeding. Moreover, the improved knowledge about intra- and inter-specific genetic relationships would facilitate germplasm utilization for lentil improvement.
