<p><b>KEY MESSAGE</b></br>Developmental context and species-specific hormone requirements are of key importance in the advancement of in vitro protocols and manipulation of seed development. Improvement of in vitro tissue and cell culture protocols in grain legumes such as embryo rescue, interspecific hybridization, and androgenesis requires an understanding of the types, activity, and balance of hormones within developing seeds. Towards this goal, the concentration of auxin, cytokinin, gibberellin, and abscisic acid (ABA) and their precursors and derivatives were measured in the developing seeds of field pea (Pisum sativum L.), chickpea (Cicer arietinum L.), lentil (Lens culinaris Medik.), and faba bean (Vicia faba L.) from 4 days after anthesis until 8 days after reaching maximum fresh weight. The importance of developmental context (developmental time and space) is demonstrated in both the differences and similarities between species for hormone profiles, especially with regard to cytokinin and ABA biosynthesis during the embryo formation. Auxin and its conjugates are significant during the pattern formation stage of all legumes; however, IAA-Asparagine appears important in the Vicieae species and its concentrations are greater than IAA from the globular stage of embryo development on in multi-seed fruits. Finally, the significance of non-polar gibberellins during lentil seed development is highlighted.</p>

There are three main kinds of chickpeas: Desi, which has small, darker seeds and a rough coat; Bombay, which has slightly larger dark seeds; and Kabuli, which has lighter coloured seeds with a smooth coat. Chickpeas are an excellent source of the essential nutrients, iron, folate, phosphorus, protein and dietary fiber. Chickpeas are low in fat and most of this is polyunsaturated. Desi chickpeas have a markedly higher fiber content than Kabulis and hence a very low glycemic index which may make them suitable for people with blood sugar problems. The plant grows to between 20–50 cm high and has small feathery leaves on either side of the stem. Chickpea pods are short in length containing 2-3 seeds. ... [more]


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. ... [more]


Pea (Pisum sativum L.) is one of the first domesticated crops, and was the model crop for the foundational genetic studies by Gregor Mendel, which he first reported in 1865. Pea is grown in most temperate regions of the world with annual production over the past decade of 10-12 million tonnes of field pea and 14-17 million tonnes of vegetable pea. Pea belongs to the Leguminosae family and consists of two species, P. fulvum and P. sativum with several ‘wild’ subspecies of P. sativum. Canada is the leading producer and exporter of field pea in the world. Saskatchewan is the leading province in pea production followed by Alberta and Manitoba. ... [more]


Faba bean is an annual legume that thrives in relatively cooler growing climates. It is one of the best nitrogen fixers among the grain legumes deriving up to 74% of its nitrogen from the atmosphere and leaving soil nitrogen balances positive (Amanuel et al., Biol Fertil Soils 32:353–359). Nutritionally, it is a good source of dietary fiber, protein, phosphorus, copper and manganese, and a very good source of folate. It is also very low in saturated fat, cholesterol and sodium. Faba bean has an erect growth habit with stiff stems and long pinnate, gray-green leaves. The pods are long with a downy interior and contain 3-8 seeds. Faba bean is still often grown as a cover crop to prevent erosion, because they can overwinter and because as a legume, they fix nitrogen in the soil. ... [more]
