Abstract

Drought stress affects plant productivity by altering plant responses at the morphological, physiological, and molecular levels. In this study, we identified physiological and genetic responses in × hybrid clones 72-30 and 72-31 after 12 days of exposure to drought treatment. After 12 days of drought treatment, glucose, fructose, and sucrose levels were significantly increased in clone 72-30 under drought stress. The Fv/Fo and Fv/Fm values in both clones also decreased under drought stress. The changes in proline, malondialdehyde, and HO levels were significant and more pronounced in clone 72-30 than in clone 72-31. The activities of antioxidant-related enzymes, such as catalase and ascorbate peroxidase, were significantly higher in the 72-31 clone. To identify drought-related genes, we conducted a transcriptomic analysis in × leaves exposed to drought stress. We found 883 up-regulated and 305 down-regulated genes in the 72-30 clone and 279 and 303 in the 72-31 clone, respectively. These differentially expressed genes were mainly in synthetic pathways related to proline, abscisic acid, and antioxidants. Overall, clone 72-31 showed better drought tolerance than clone 72-30 under drought stress, and genetic changes also showed different patterns.

摘要

干旱胁迫通过改变植物在形态、生理和分子水平上的反应来影响植物生产力。在本研究中，我们确定了杂交克隆72 - 30和72 - 31在干旱处理12天后的生理和遗传反应。干旱处理12天后，在干旱胁迫下克隆72 - 30中的葡萄糖、果糖和蔗糖水平显著增加。在干旱胁迫下，两个克隆中的Fv/Fo和Fv/Fm值也都下降。脯氨酸、丙二醛和过氧化氢水平的变化显著，且在克隆72 - 30中比在克隆72 - 31中更明显。抗氧化相关酶如过氧化氢酶和抗坏血酸过氧化物酶的活性在72 - 31克隆中显著更高。为了鉴定与干旱相关的基因，我们对遭受干旱胁迫的叶片进行了转录组分析。我们分别在72 - 30克隆中发现了883个上调基因和305个下调基因，在72 - 31克隆中发现了279个和303个。这些差异表达基因主要参与脯氨酸、脱落酸和抗氧化剂的合成途径。总体而言，在干旱胁迫下，克隆72 - 31比克隆72 - 30表现出更好的耐旱性，并且遗传变化也呈现出不同的模式。
