A study on the effect of endophyte fungus, Piriformospora indica, on the yield and phytochemical changes of globe artichoke (Cynara scolymus L.)leaves under water stress
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2014, Vol 2, Issue 6
Abstract
Piriformospora indica, a cultivable root colonizing endophytic fungus of Sebacinales, promotes plant growth and confers resistance against biotic and abiotic stress. The fungus has also the ability to colonize the roots of many varieties of plant species. The goal of present study was to clarify the colonization ability of P.indica in artichoke roots and the respond of plant to water stress. Results showed that Globe artichoke (Cynara scolymus L.) was strongly colonized by the fungus. The fungus retarded the droughtinduced malfunctioning in the photosynthetic pigments. Proline, an osmotic signal adjustment was clearly increased during water stress in colonized plants. Total phenol, flavonoid contents, radical scavenging activities, and photosynthetic pigments were influenced by treatments. Based on the obtained results and observations, it can be concluded that P.indica as an elicitor enhances the plant growth efficiency under sever conditions. Thus, P.indica- colonized Cynara scolymus L., provides a good model system to study root-to-shoot communication in secondary metabolites production.
