Abstract

Research into the physiological bases of symbiont interactions in vesicular­ arbuscular (VA) endomycorrhizae has occurred relatively recently. The last review on mycorrhizae in this series ( 1 2 1 ) was mainly devoted to>ectomycor221 0066-4294/88/0601 -0221$02.00 SMITH & GIANINAZZI-PEARSON rhizae, reflecting the lack of knowledge of VA mycorrhizal physiology at that time. Although the fungi had been identified as members of the Endogo­ naceae and progress had been made in pinpointing the causes of the growth responses of plants to VA mycorrhizal infection, physiological research was only really given impetus at the "Endomycorrhizas" meeting at Leeds in 1974 (147). Many of the hypotheses proposed there have stimulated experimenta­ tion and advanced our understanding of the functioning of VA mycorrhizal roots and the physiology of mycorrhizal plants. It has become clear that mycorrhizae are an integral part of the plant (69) and that in nature most plant species (more than 80%) have a root system that is really a VA mycorrhizal system.
