Cytological studies in the genus Indigofera L.

Taxonomical, Anatomical, Cytological and Palynological Assessment of a Germplasm of Indigofera Tinctoria L. (Fabaceae): An Ayurvedic Plant

“…The somatic chromosome complement in I. tinctoria is symmetric in nature (Figure 3:B). The chromosome number is in conformity with earlier report of Gupta and Agarwal 23 ; however, the authors suggested a different karyotype formula (1M+5m+2sm) for the species. Meiosis: Meiocytes at diplotene-diakinesis (Figure 3:C) and MI (Figure 3:D-E) always show 2n=16 chromosomes with preponderance of rod bivalents as reported earlier by Ghosh et al 24 (2016).…”

Karyomorphological Analysis of <i>Indigofera santapaui</i> (Leguminosae: Papilionoideae) An Endemic Species from North Western Ghats and Maharashtra of India

“…Indigofera is one of the highly diversified genera containing annual herbs to perennial shrubs and distributed throughout India. The genus is dominated by basic number x=8 (182 taxa) and rarely x=7 (5 taxa) and the genus consists of always median and sub-median types of chromosomes (Singh and Roy 1970, Bhatt and Sanjappa 1975, Gupta and Agarwal 1982, Sanjappa and Dasgupta 1983, Rice et al 2015. Among Indian species of Indigofera, the seven trifoliate leaved species namely I. barberi Gamble, I. glandulosa Wendl., I. karuppiana Pallithanam, I. pedicellata Wight &.…”

Meiotic Configurations and Secondary Chromosome Associations in <i>Indigofera tinctoria</i> L. (Family: Fabaceae)

“…A statistical analysis of the cytological data reveals that the basic chromosome number (x) is probably five (selective doubling of chromosomes possibly as x=5, n=8). Gupta and Agarwal (1982) evaluated the genus Indigofera on karyomorphology and suggested the base number was four. In the present investigation, the meiocytes show a total lack of multivalent formation and variable number of associations indicating possible allopolyploid lineage of the species.…”
