transcriptome of duckweed (Spirodela polyrhiza) under different lights treatment

Red light (RL) and blue light (BL) greatly influence the growth and physiological processes of duckweed. Physiological and molecular mechanisms underlying the response of duckweed to different light qualities remain unclear. This study employed physiological and transcriptomic analyses on duckweed, Spirodela polyrhiza, to elucidate its differential response mechanisms under RL, BL, and white light (WL) conditions. Changes in growth indicators, ultrastructure alterations, metabolite accumulations, and differentially expressed genes (DEGs) were measured.

红光（Red Light, RL）与蓝光（Blue Light, BL）对浮萍的生长及生理过程具有显著调控作用。目前，浮萍响应不同光质的生理与分子机制尚未阐明。本研究以紫背浮萍（Spirodela polyrhiza）为实验材料，通过生理与转录组学分析，解析其在红光、蓝光及白光（White Light, WL）培养条件下的差异化响应机制。本研究测定了生长指标变化、超微结构改变、代谢物积累量以及差异表达基因（Differentially Expressed Genes, DEGs）的表达情况。
