Ten germplasms of three Crotalaria species viz. C. pallida (Acc. No. 4250, 4803, 4805, 4806, and 4807), incana 4790, 4801, 4804, 4809), juncea (Local) were investigated cytogenetically through Chromomycin A3 (CMA) 4′-6 diamidino-2-phenylindole (DAPI) fluorescent bandings. After CMA-banding, 10 showed 31 centromeric 34 terminal bands which indicated a tendency accumulating GC-rich sequences at r...

An enzymatic maceration and Giemsa staining method was used to compare the karyotypes of Crotalaria laburnifolia (trifoliate) C. spectabilis (simple leaves) species belonging distinct morphological sections with different degrees floral specialization. Both taxa share a 2n=16, asymmetric chromosome complement, relatively similar karyotypic formulae. However, differences in chromosome-SAT, sizes...

The moth Utetheisa ornatrix (family Arctiidae) depends on pyrrolizidine alkaloids (PAs) for defense. It sequesters the toxins as a larva from its food plants (Crotalaria species: family Fabaceae) and retains them through metamorphosis. We report here that PA-possession in the adult female U. ornatrix has a life-shortening effect, suggesting that, by putting the compounds to use, the moth may be...

The African Japanagromyza Sasakawa are revised, including a key and genitalic illustrations, and the limits of the genus are discussed. Nine species are recognized, which include four previously described species and four newly described species: J. crinicolis spec. nov.; J. dolobrata spec. nov.; J. laureata spec. nov.; J. nesiota spec. nov. The ninth species ("female 1") is described but not f...

Abstract Background Diversification of global food systems through exploration traditional varieties and wild edible plant species is a focal mitigation strategy for security worldwide. The present study determined the phenomic diversity locally available, affordable climate-resilient cultivated Crotalaria breeding purposes. Methods Seed samples were collected from different administrative coun...

Inspite of considerable development in contraceptive technology, search for female antifertility agent in plants continues to be a potential area of investigation. The ethanol extract of Crotalaria juncea seeds which showed promising antiovulatory activity in female albino rats was examined for the isolation of its active fractions. Two fractions were obtained using Thin Layer Chromatography ...
