硫在植物次生代谢中起着至关重要的作用,特别是在硫代葡萄糖苷的生物合成中,硫作为核心结构元件参与分子调控机制。此外,硫代谢与氮同化错综复杂,突出其在植物生理过程中的多面作用。光,另一个关键的非生物决定因素,直接调节作物生产力,光强度控制基本过程,如生长动力学和光合效率。本研究旨在阐明光胁迫和硫缺乏对受控环境条件下西兰花(Brassica oleracea var. italica)生长和水分动力学的影响,探讨光胁迫和硫缺乏单独和联合胁迫下的生理和分子机制。结果表明,缺硫对植物水分关系的影响强于光胁迫,而光胁迫主要影响光合活性和生物量积累。复合应激导致更明显的生理反应,包括不同于单一应激处理的不同的水通道蛋白调节模式。这些发现提示了一种有助于维持水分平衡的补偿机制,强调了硫有效性、光强和植物适应策略之间复杂的相互作用。
期刊介绍:
Plant Biology is an international journal of broad scope bringing together the different subdisciplines, such as physiology, molecular biology, cell biology, development, genetics, systematics, ecology, evolution, ecophysiology, plant-microbe interactions, and mycology.
Plant Biology publishes original problem-oriented full-length research papers, short research papers, and review articles. Discussion of hot topics and provocative opinion articles are published under the heading Acute Views. From a multidisciplinary perspective, Plant Biology will provide a platform for publication, information and debate, encompassing all areas which fall within the scope of plant science.
