Mycorrhizal fungi regulate daily rhythm of circadian clock in trifoliate orange under drought stress

Original language description

The circadian rhythm of plants is associated with stress responses; however, it is not clear whether increased host plant drought tolerance by arbuscular mycorrhizal fungi (AMF) is associated with changes in the circadian clock. The present study aimed to analyze the effect of Funneliformis mosseae (Nicol. &amp; Gerd.) Schussler &amp; Walker on the circadian clock gene expression patterns in trifoliate orange (Poncirus trifoliata L. Raf.) along with gas exchange, abscisic acid (ABA) levels and antioxidant enzyme gene expression under well-watered (WW) and drought stress (DS) conditions. Plant growth, net photosynthetic rate, stomatal conductance and ABA levels were significantly higher in AMF- than in non-AMF-inoculated plants regardless of soil water regimes. Six circadian clock genes, including PtPRR7, PtLHY, PtCCA1, PtGI, PtPIF3 and PtSRR1, were identified and showed rhythmic expression patterns over the course of the day. The AMF inoculation reduced the expression of most circadian clock genes in different time periods. However, AMF treatment significantly increased PtPRR7 and PtGI expression at 5:00 p.m. under WW and DS conditions, PtLHY expression at 1:00 a.m. and PtSRR1 expression at 9:00 p.m. At 1:00 a.m., AMF inoculation up-regulated the expression of the circadian clock genes PtPRR7, PtCCA1, PtLHY and PtPIF3 and the antioxidant enzyme genes PtFe-SOD, PtMn-SOD, PtCu/Zn-SOD, PtPOD and PtCAT1. Correlation analysis revealed that these changes in circadian clock gene expression were associated with antioxidant enzyme gene expression, root ABA and gas exchange. We concluded that mycorrhizal fungi have the ability to regulate the daily rhythm of the circadian clock in trifoliate orange plants in response to drought.
