Conventional farming reduces the activity of earthworms: Assessment of genotoxicity test of soil and vermicast
Jaswinder Singh,Jaswinder Singh,Jaswinder Singh,Sharanpreet Singh,Adarsh Pal Vig,Sartaj Ahmad Bhat,Swarndeep Singh Hundal,Rui Yin,Rui Yin,Martin Schädler,Martin Schädler +10 more
TL;DR: The activity of earthworms was less in an agricultural field where there may have been more application of chemical fertilizers and pesticides compared to a site using more organic manure with reduced genotoxicity.

Natural triploidy in phyto-oestrogen producing Curcuma species and cultivars from Thailand
Tidarat Puangpairote,Charun Maknoi,Thaya Jenjittikul,Kesara Anamthawat-Jónsson,Puangpaka Soontornchainaksaeng +4 more
TL;DR: Investigating the extent of triploidy and the level of genome size variation among commercially cultivated phyto-oestrogen producing Curcuma and related species in Thailand revealed three distinct groups: diploid C.comosa, C.latifolia and C. latifolia, and tetraploidC.caesia, which showed statistically significant difference in genome size from all other Triploid taxa.

Studies on Nuclear DNA and Meiotic Chromosomes in 8 Species on Mammillaria
TL;DR: Meiotic studies of Pollen Mother Cell (PMCs) and 4C DNA content from root tip cells of 8 species of Mammillaria of the family Cactaceae revealed significant interspecific variations in the genome, leading to genetic drift among the species.
Journal ArticleDOI
Cytophotometric Estimation of 4C DNA Content and Chromosome Analysis in Four Species of Astrophytum Lem. of the Family Cactaceae
TL;DR: The structural alterations in the chromosomes as well as loss or addition of highly repetitive sequences in the genome caused variations in the nuclear DNA at interspecific level indicating a micro-change of nuclear material during evolution.

Abscisic acid promotes development of somatic embryos on converted somatic embryos of Corydalis yanhusuo (Fumariaceae)
TL;DR: Histological and scanning electron microscopic studies confirmed the direct origin of embryos from the epidermal layer of cells of Corydalis yanhusuo as direct development of somatic embryos in the region at the junction of cotyledonary leaf and root when cultured on Murashige and Skoog basal medium.
