Investigating Effects of a Prescribed Spring Fire on Symbiosis between Mycorrhiza Fungi and Range Plant Species
Fire is one of the incorporate vegetation management practices for grasslands and semi-arid rangelands. It may affect symbiotic relationship between range plants and mycorrhiza. Accordingly, this research was aimed to investigate the effects of a spring prescribed fire on the symbiotic relationships between mycorrhiza and 6 plant species. The study was conducted in a semi-arid steppe rangeland ...
متن کاملInteraction Efect between Water Deficit and Mycorrhizal Symbiosis on the Quantitative and Qualitative Yield of Sainfoin (Onobrychis sativa L.)
Water stress is one of the most important factors limiting the growth and production of crops in arid and semi-arid regions. To evaluate the effect of mycorrhizal fungi species on the growth and yield (quantity and quality) of Onobrychis sativa under water deficit condition, a greenhouse factorial experiment based on completely randomized design (CRD) with three replications was conducted in 20...
متن کاملBacterial Leaf Symbiosis in Angiosperms: Host Specificity without Co-Speciation
Bacterial leaf symbiosis is a unique and intimate interaction between bacteria and flowering plants, in which endosymbionts are organized in specialized leaf structures. Previously, bacterial leaf symbiosis has been described as a cyclic and obligate interaction in which the endosymbionts are vertically transmitted between plant generations and lack autonomous growth. Theoretically this allows ...
متن کاملThe origin of synergistic symbiosis.
A dominant theme in the history of life has been the evolutionary innovations of cooperative symbioses: the first genomes near the origin of life, integrated prokaryotic cells, the complex symbiotic communities that evolved into modern eukaryotic cells, lichens, mycorrhizae, and so on. In this paper, a model of cooperative symbiosis that shows a threshold condition for the evolution of cooperat...
متن کاملThe Irreversible Loss of a Decomposition Pathway Marks the Single Origin of an Ectomycorrhizal Symbiosis
Microbial symbioses have evolved repeatedly across the tree of life, but the genetic changes underlying transitions to symbiosis are largely unknown, especially for eukaryotic microbial symbionts. We used the genus Amanita, an iconic group of mushroom-forming fungi engaged in ectomycorrhizal symbioses with plants, to identify both the origins and potential genetic changes maintaining the stabil...
متن کاملImprovement of Growth and Stimulation of Biosynthesis Pathway of Polyphenols in Melissa officinalis L. Colonized by Arbuscular Mycorrhizal
The increasing demand for medicinal plants has amplified the importance of the development of effective methods for enhancing the cultivation of these plants. The association of arbuscular mycorrhizal (AM) fungi with medicinal plants has been found to alter the level of secondary metabolites by affecting the plant metabolism. Lemon balm (Melissa officinalis L.), is an important medicinal plant ...
