Integrative Physiological, Metabolomic and Transcriptomic Analyses Uncover the Mechanisms Underlying Differential Responses of Two <i>Anubias</i> Genotypes to Low-Temperature Stress.

ABSTRACT: Anubias (Araceae) is a globally important group of ornamental aquatic plants. However, when temperatures drop to 10 °C, most species suffer obvious frostbite from cold stress, restricting winter cultivation and broader application. This study focused on two Anubias genotypes with distinct cold tolerance, adopting an integrated approach combining phenotypic, physiological, metabolomic, and transcriptomic analyses to reveal the mechanisms underlying their differential cold tolerance. Under 10 °C cold stress, compared with normal temperatures, the leaves of cold-tolerant Anubias sp. 'Long Leaf' (Jian) showed no significant frostbite, while cold-sensitive Anubias barteri var. nana 'Coin Leaf' (Jin) had clear frost damage. Both genotypes exhibited increased le
