  • Characterization of the BPC genes in alfalfa and functional verification of MsBPC10 in salt tolerance (2026) · BMC Plant Biology · doi

    Background Soil salinization severely restricts the growth and forage yield of Medicago sativa (alfalfa), a globally critical leguminous forage crop, yet the regulatory mechanisms governing its salt tolerance remain incompletely understood-especially the role of the BASIC PENTACYSTEINE (BPC) transcription factor family, which has been implicated in plant stress responses but never systematically investigated in alfalfa’s salt adaptation processes.

  • Drought–salinity interaction suppresses seed germination and seedling growth in alfalfa by altering water status, membrane stability, and antioxidant responses (2026) · Frontiers in Plant Science · doi

    The interactive effects of drought and salinity stress on early alfalfa establishment and the underlying physiological regulatory mechanisms remain insufficiently understood. The study aims to fill this knowledge gap.

  • Drought–salinity interaction suppresses seed germination and seedling growth in alfalfa by altering water status, membrane stability, and antioxidant responses (2026) · Frontiers in Plant Science · doi

    However, the integrated responses of alfalfa during early establishment to combined drought and salinity stress, particularly the physiological links among water status, membrane stability, antioxidant defense, seed germination, and seedling growth, remain insufficiently understood.
