    Polyploids broadly generate novel haplotypes from trans-specific variation in Arabidopsis arenosa and Arabidopsis lyrata. by Magdalena Bohutínská, Eliška Petříková, Tom R Booker, Cristina Vives Cobo, Jakub Vlček, Gabriela Šrámková, Alžběta Poupětová, Jakub Hojka, Karol Marhold, Levi Yant, Filip Kolář, Roswitha Schmickl

    Published 2024-12-01
    “…Polyploidy, the result of whole genome duplication (WGD), is widespread across the tree of life and is often associated with speciation and adaptability. It is thought that adaptation in autopolyploids (within-species polyploids) may be facilitated by increased access to genetic variation. …”

    Soil Physicochemical and Biological Properties of Paddy-Upland Rotation: A Review by Wei Zhou, Teng-Fei Lv, Yong Chen, Anthony P. Westby, Wan-Jun Ren

    Published 2014-01-01
    “…Paddy-upland rotation fields are unique from other wetland or upland soils, because they are associated with frequent cycling between wetting and drying under anaerobic and aerobic conditions; such rotations affect the soil C and N cycles, make the chemical speciation and biological effectiveness of soil nutrient elements varied with seasons, increase the diversity of soil organisms, and make the soil physical properties more difficult to analyze. …”
