Karyotype studies in Mucuna macrocarpa Wall and Mucuna sanjappae Aitawade et Yadav (Fabaceae) from India

The genus Mucuna Adans. is represented by 100 species distributed in the world tropics (Lackey 1981; Mabberley 2005). India is one of the natural center of origin of Mucuna. Up to now there are 11 species and three varities of Mucuna reported in India. Mucuna pruriens is useful for medicinally where...

Zusammenfassung:The genus Mucuna Adans. is represented by 100 species distributed in the world tropics (Lackey 1981; Mabberley 2005). India is one of the natural center of origin of Mucuna. Up to now there are 11 species and three varities of Mucuna reported in India. Mucuna pruriens is useful for medicinally where as Mucuna pruriens var. utilis used for food and fodder purpose (Janardhanan and Lakshmanan 1985; Pugalenthi et al. 2005). Mucuna sanjappae is one of the important medicinal plants since it contains high amount of L-dopamine, which significantly proved as antiparkinson’s drug (Patil et al. 2015). Mucuna macrocarpa is also medicinally important because of its antileukemic effects on human leukemic cells (Kaun-Hung et al. 2012). For the characterization and identification of the proper species the chromosome studies are utmost important. The present work is the first report on karyomorphological analysis of two species of Indian Mucuna viz. M. sanjappae which is endemic to northern Western Ghats, Maharashtra and Mucuna macrocarpa from North-East India. Both the species represented by the chromosome number of 2n = 22. The karyotype formula for M. sanjappae is 11m, while that for M. macrocarpa is 10m + 1M. Total chromosome length in M. sanjappae is 25.15µm while that in M. macrocarpa it is 25.58 µm. Both the species show highly symmetrical karyotype i.e. (1a).
