AI Article Synopsis
- The study analyzed phytohormone levels in resistant and susceptible wheat varieties affected by the fungus Helminthosporium sativum using an immunoenzyme assay.
- In resistant wheat, cytokinin levels rose while maintaining a stable ratio of IAA (Indole-3-acetic acid) to ABA (Abscisic acid) during infection.
- In contrast, the susceptible wheat variety showed an increase in ABA levels, highlighting the importance of hormones in plant resistance to fungal infections.
Article Abstract
Using immunoenzyme assay, we studied the levels of phytohormones in resistant and susceptible varieties of wheat infected with Helminthosporium sativum. The infection of wheat with this pathogen leads to an increase in cytokinins in plants of the resistant variety in the presence of stable IAA/ABA ratio. The level of ABA increases in the infected plants of the susceptible variety. The role of hormones in the mechanisms of plant resistance to fungal infections is discussed.
