    Flooding tolerance in interspecific introgression lines in Zea

    Nicaraguan teosinte Zea nicaraguensis, a species found in frequently flooded areas, is useful germplasm for breeding flooding-tolerant maize. Mano and Omori select flooding-tolerant lines using a library of introgression lines (ILs), each containing a chromosome segment from Z. nicaraguensis in the maize (Z. mays) inbred Mi29. The most flooding-tolerant line they identify contains a Z. […] More

    Flowering and morphology responses to high latitudes

    Timing of flowering is an adaptive trait regulated by environmental cues and has been intensively studied in annual plants, but in perennials it is currently not well characterized. Quilot-Turion et al. apply cold treatments to two locally adapted populations of the perennial Arabidopsis lyrata from central Europe and Scandinavia and study responses to vernalization. They find […] More

    Comparative genomics of domestication in Asian Vigna

    Comparative genomics of domestication in Asian Vigna Rice bean (Vigna umbellata) was domesticated in Southeast Asia and is a scientifically neglected crop with under-exploited potential. Isemura et al. compare its domestication QTLs with those of azuki bean (V. angularis) of East Asian origin. The inheritance of domestication-related traits is found to be so simple that […] More

    Chromosome region for high hydraulic conductance in rice

    Chromosome region for high hydraulic conductance in rice The rate of photosynthesis in paddy rice, Oryza sativa, often decreases around noon on sunny days because of water stress even under submerged conditions. Adachi et al. study a high-yielding indica variety with a relatively high hydraulic conductance in comparison with a standard, lower-yielding japonica variety, and […] More
