We will capitalise on our previous discovery of novel phenotypic variation in arbuscular mycorrhizas in mutant and wild-type tomato, to explore development and function of the symbiosis at the molecular-genetic level. We will clone and sequence the gene responsible for mycorrhiza-defective phenotypes to provide inferences on function and relations with other genes. We will determine if plant defence blocks fungal colonisation in the mutant and/or varies with different wild-type phenotypes and explore molecular mechanisms of nutrient transfer from fungus to plant in relation to phenotypic diversity. The project will provide new insights into genome/phenome interactions controlling this widespread beneficial symbiosis.

我们将利用我们以前发现的突变体和野生型番茄丛枝菌根的新表型变异，在分子遗传水平上探索共生的发展和功能。我们将克隆和测序的基因负责菌根缺陷的表型，以提供功能和与其他基因的关系的推断。我们将确定植物防御是否会阻止突变体中的真菌定殖和/或随不同的野生型表型而变化，并探索与表型多样性有关的从真菌到植物的营养转移的分子机制。该项目将为控制这种广泛有益共生的基因组/表型组相互作用提供新的见解。
