Lens culinaris

Overview
GenusLens
Speciesculinaris
Common NameCultivated Lentil
AbbreviationL.culinaris

Lentil (Lens culinaris Medik.) is an important pulse crop with annual production of 3-4 Mt across 70 countries (Cubero et al. 2009. DOI 10.1079/9781845934873.0000; pg. 13). Lentils are a good source of protein, carbohydrates, micronutrients and vitamins for human nutrition and is consumed in more than 120 countries. Furthermore, their small seed size and flat shape make them relatively quick cooking and easily decorticated compared to most other grain legumes (Sharpe et al. 2013. BMC Genomics. DOI 10.1186/1471-2164-14-192). The Lentil plant has a bushy growth habit with a height of about 40 cm; the seeds are lens-shaped and usually grow two per pod.

Nutrition

Lentils offer many health benefits for human nutrition since they are high in fibre, protein, complex carbohydrate and low in calories and fat. The high level of soluble fiber and complex carbohydrates found in lentils can help people stabilize blood sugar levels. The high protein content can help people who want to boost their protein intake. Using lentils to replace meat can reduce saturated fat intake while supplying important nutrients for your daily diet since lentils are an excellent source of potassium, folate, iron, mangansese and other minerals. Also, they are naturally gluten-free can help people who are gluten intolerant. Therefore, lentils can be your perfect choice if you are looking for healthy food options.

Morphology

Lens culinaris (cultivated lentil) is generally between 20 and 30 cm tall, but some cultivars can grow as tall as 75 cm and as short as 15 cm. Lentil is indeterminate which means growth habits of lentil can be considerable different: erect to semi-erect and compact growth to branched low bushy forms. Other morphological features, like number of leaflets, flower colour, seed size, cotyledon colour and days to maturity also exhibit a wide range of variations. The variations are mainly determined by genotypes but can be fairly affected by environmental conditions.

Lentil is an economically important pulse crop for Canada produced mainly for the export market. In conventional breeding programs, several segregating generations must be grown in order to reach a certain level of homozygosity that allows the selection of traits of interest. In contrast, double-haploid (DH) technology produces instant homozygosity and thus can significantly reduce the time required for developing new varieties. The efficiency of the lentil breeding program will also be improved through the reduction in the population size required for screening.
2009
Colletotrichum truncatum is a pathogen of several leguminous plant species where it causes a disease called anthracnose. Host specialization, infertility and genetic differentiation among isolates from different hosts have been demonstrated. In the population of C. truncatum from lentil two races were described. Detailed histological studies of the infection process by isolates of both races have revealed quantitative rather than qualitative differences.
2009
Lentil anthracnose is currently the most important lentil disease in Saskatchewan. In a project about to be completed on molecular aspects of this pathogen, we generated an extensive library of genes activated by the anthracnose fungus and by lentil during the infection process. In order to fully benefit from the investment made in this NSERC-CRD, we received one-year funding to confirm the function of a number of genes in the anthracnose fungus, Colletotrichum truncatum, that we have identified and believe to be involved in virulence of the fungus.

2009
A set of 1107 legume cross species orthologous sequences (COS) were amplified from Lens culinaris (CDC Redberry and Eston) and L. ervoides (L01-827a and IG 72815). Sequences were aligned and SNPs identified. A subset of 110 KASP assays were designed for use in L. culinaris. An Illumina GoldenGate array of 768 SNPs was designed for use in L. ervoides or interspecies hybrid populations between Lc and Le.
2008 to 2009
Mixture of eight cultivars with varying seed phenotypes: Indian Head, Commando, CDC LeMay, CDC Robin, and breeding lines 1899T-50 and 1788-4 (CDC, Univ. Saskatchewan, Saskatoon, Canada) All developmental stages of seeds and very young fertilized pods were harvested from mature plants, and divided into the following lots: very young fertilized ovaries, young ovules, enlarging seeds, cotyledons of fully filled seed, seed coats of fully filled seeds. cDNA library was made from a mixture of equal amounts of mRNA extracted from each of the above tissues.
