ABSTRACT = {Seedlings of <i>Taxus chinensis</i> var. <i>mairei</i> were used as experimental materials to study the adaptation of <i>Piriformospora indica</i> to this plant under water stress. The materials were divided into two groups, namely, with or without inoculation with <i>P. indica</i>. Each group was subjected to four different levels of water stress. Vitality and physiological and biochemical indexes of the roots of <i>T. chinensis</i> var. <i>mairei</i> were regularly measured. Under water stress, <i>T. chinensis</i> var. <i>mairei</i> had significantly decreased root vitality; root vitality was higher in inoculated roots than in uninoculated roots. Under intense water stress, the inoculated roots had a higher soluble sugar content than the uninoculated roots. Under water stress, <i>T. chinensis</i> var. <i>mairei</i> experienced decreased activity of aerobic respiratory metabolic enzymes. The activity of anaerobic respiratory metabolic enzymes and alcohol dehydrogenase initially increased and then decreased, whereas that of lactate dehydrogenase increased. The inoculated roots had a higher activity of respiratory metabolic enzymes than the uninoculated roots. As water stress was further intensified, the roots had significantly decreased activity of aerobic respiratory metabolic enzymes and significantly increased activity of anaerobic respiratory metabolic enzymes. The activity of respiratory metabolic enzymes decreased faster in the uninoculated roots than in the inoculated roots. This study demonstrated that <i>Piriformospora indica</i> plays a positive role in enhancing the antihypoxic ability of <i>T. chinensis</i> var. <i>mairei</i>, thereby alleviating plant damage due to water stress.},
