DESCRIPTION:Arbuscular mycorrhiza (AM) is an ancient symbiosis between pla
 nts and glomeromycotan fungi that is extremely widespread in the plant kin
 gdom and is based on nutritional benefits to both symbiotic partners. The 
 plant receives mineral nutrients\, especially phosphate from the fungus an
 d in return provides the fungus with carbohydrates and lipids. As a result
 \, AM can significantly increase plant growth in low nutrient soils. For s
 ymbiosis establishment AM fungi colonize the root interior. This involves 
 distinct and genetically separable developmental steps that are largely un
 der plant control. They include drastic plant cell rearrangements that pre
 cede differentiation of fungal hyphae into particular shapes inside plant 
 cells. We are interested in the plant molecular mechanisms required for in
 itiation of AM symbiosis and for the rearrangement of root cortex cells al
 lowing formation of highly-branched fungal arbuscules\, which mediate nutr
 ient exchange. In addition\, we work towards elucidating the genetic deter
 minants of AM-mediated plant growth increase. Recent progress in our under
 standing of AM development and function will be presented.
