Abstract

Although characterization of plant interactions has become a research hotspot to assess the adaptability of endangered plants, the underlying molecular basis remains elusive. Dove tree (Davidia involucrata Baill.) seedlings were watered with distilled water (CK), leaf water extract (0.025 g mL-1) and branch water extract (0.1 g mL-1) from Cornus controversa, respectively. Subsequently, the morphology, biomass and gene expression levels of DiSOC1-b and DiCCoAOMT1 were analyzed. The results showed that morphological traits and biomass accumulation of D. involucrata seedlings were decreased by the addition of leaf water extracts, and increased by branch water extracts. Moreover, the gene expression level of DiSOC1-b was significantly down-regulated, while the gene expression level of DiCCoAOMT1 was significantly up-regulated in the stems and roots of D. involucrata upon treatment with leaf water extracts of C. controversa. In contrast, the gene expression level of DiSOC1-b was significantly up-regulated in the leaves and stems, while the gene expression level of DiCCoAOMT1 was significantly down-regulated in the roots of D. involucrata upon treatment with branch water extracts of C. controversa. In addition, the expression level of DiSOC1-b was positively correlated with most of morphological traits and total biomass (P < 0.05), while DiCCoAOMT1 was negatively correlated with the majority of morphological traits in D. involucrata seedlings (P < 0.05). Taken together, these results suggest that water extracts from the leaves and branches of the C. controversa exhibit opposite allelopathic effects and affect the expression levels of genes related to growth (DiSOC1-b) and environmental adaptability (DiCCoAOMT1) in D. involucrata seedlings.
山茱萸水提取物对与珙桐幼苗生长相关的 DiSOC1-b 和 DiCCoAOMT1 基因表达水平的影响
尽管植物相互作用的表征已成为评估濒危植物适应性的研究热点,但其潜在的分子基础仍然难以捉摸。分别用蒸馏水(CK)、山茱萸叶水提取物(0.025 g mL-1)和山茱萸枝水提取物(0.1 g mL-1)浇灌珙桐(Davidia involucrata Baill.)幼苗。随后,对 DiSOC1-b 和 DiCCoAOMT1 的形态、生物量和基因表达水平进行了分析。结果表明,加入叶片水提取物后,D. involucrata幼苗的形态特征和生物量积累减少,而加入枝条水提取物后,幼苗的形态特征和生物量积累增加。此外,用 C. controversa 的叶水提取物处理 D. involucrata 的茎和根时,DiSOC1-b 的基因表达水平显著下调,而 DiCCoAOMT1 的基因表达水平显著上调。相反,用 C. controversa 的枝叶水提取物处理 D. involucrata 后,DiSOC1-b 在叶和茎中的基因表达水平明显上调,而 DiCCoAOMT1 在根中的基因表达水平明显下调。此外,DiSOC1-b 的表达水平与 D. involucrata 幼苗的大多数形态特征和总生物量呈正相关(P < 0.05),而 DiCCoAOMT1 与 D. involucrata 幼苗的大多数形态特征呈负相关(P < 0.05)。综上所述,这些结果表明,从C. controversa的叶片和枝条中提取的水提取物具有相反的等位基因效应,会影响D. involucrata幼苗中与生长(DiSOC1-b)和环境适应性(DiCCoAOMT1)相关基因的表达水平。
