Metabolo‐Transcriptomics Analyses Reveal Alfalfa Adaptation to Combined Saline‐Alkali and Low‐Temperature Stress in the Field

open access: yesPlant Biotechnology Journal, Volume 24, Issue 2, Page 504-519, February 2026.
ABSTRACT Alfalfa (Medicago sativa L.) is known as the ‘King of Forage’ because of its high protein content and excellent palatability. Alfalfa productivity is adversely affected in cold regions with saline‐alkali soils. However, the mechanisms underlying the response of alfalfa to combined saline‐alkali and low‐temperature stress under field conditions
