Abstract
Mitochondrial processes are implicated in plant response to biotic stress caused by viruses, actinomyces, bacteria, and pests, but its function in defense against fungal invasion remain unclear. Here, we investigated the role and regulation of mitochondrial alternative oxidase (AOX) in response to black spot disease caused by hemibiotrophic fungus Marssonina brunnea in poplar. M. brunnea inoculation induced the transcript amount of AOX1a gene in the mitochondrial electron transport chain (miETC) and the biosynthetic genes of jasmonic acid (JA) and ethylene (ET) with accumulation of these phytohormones in poplar leaf, while inhibiting the transcript amount of mitochondrial cytochrome c oxidase gene (COX6b) and genes related to SA. The enhanced AOX reduced poplar susceptibility to M. brunnea with higher ATP/ADP ratio while AOX repressor caused a reverse effect. Exogenous JA and 1-aminocyclopropane-1-carboxylic acid (ACC, biosynthetic precursor of ET) inhibited the transcript amount of COX6b and consequently increased the ratio of AOX pathway to total respiration. Further, transcription of CYS C1 and CYS D1 genes catalyzing cyanide metabolism was induced, while the cysteine (CYS substrate) levels reduced upon M. brunnea inoculation; exogenous JA and ACC mimicked the effect of M. brunnea infection on cysteine. Exogenous SA enhanced, while JA and ACC reduced, poplar susceptibility to M. brunnea. Moreover, inhibiting AOX completely prohibited JA- and ET-increased tolerance to M. brunnea in poplar. These observations indicate that JA- and ET-induced mitochondrial AOX pathway triggers defense against M. brunnea in poplar. This effect probably involves cyanide. These findings deepen the understanding of plant-pathogenic fungi interactions.
