The main objective of this study was to investigate the influence of on the growth of Tartary buckwheat plants. This study highlighted that the roots of Tartary buckwheat can be colonized by and that this fungal endophyte improved plants height, fresh weight, dry weight, and grain yield. In the meantime, the colonization of in Tartary buckwheat leaves resulted in elevated levels of photosynthesis, plant hormone content, antioxidant enzyme activity, proline content, chlorophyll content, soluble sugars, and protein content. Additionally, the introduction of to Tartary buckwheat roots led to a substantial rise in the levels of flavonoids and phenols found in the leaves and seeds of Tartary buckwheat. In addition, colonization reduced the content of malondialdehyde and hydrogen peroxide when compared to non-colonized plants. Importantly, the drought tolerance of Tartary buckwheat plants is increased, which benefits from physiology and bio-chemical changes in plants after colonized. In conclusion, we have shown that can improve systematic resistance and promote the growth of Tartary buckwheat by enhancing the photosynthetic capacity of Tartary buckwheat, inducing the production of IAA, increasing the content of secondary metabolites such as total phenols and total flavonoids, and improving the antioxidant enzyme activity of the plant.
本研究的主要目的是调查[未提及的某种因素]对苦荞麦植株生长的影响。该研究强调，苦荞麦的根部可被[未提及的某种真菌内生菌]定殖，且这种真菌内生菌提高了植株高度、鲜重、干重和籽粒产量。同时，[未提及的某种真菌内生菌]在苦荞麦叶片中的定殖导致光合作用水平、植物激素含量、抗氧化酶活性、脯氨酸含量、叶绿素含量、可溶性糖和蛋白质含量升高。此外，将[未提及的某种真菌内生菌]引入苦荞麦根部导致苦荞麦叶片和种子中黄酮类化合物和酚类物质的含量大幅上升。另外，与未被定殖的植株相比，[未提及的某种真菌内生菌]定殖降低了丙二醛和过氧化氢的含量。重要的是，苦荞麦植株的耐旱性增强，这得益于[未提及的某种真菌内生菌]定殖后植株的生理和生化变化。总之，我们已经表明，[未提及的某种真菌内生菌]可以通过增强苦荞麦的光合能力、诱导吲哚乙酸的产生、增加总酚和总黄酮等次生代谢产物的含量以及提高植物的抗氧化酶活性来提高系统抗性并促进苦荞麦的生长。
