Impact of combined abiotic stress and pathogen infection on plants. The impact of combined abiotic stresses (mainly drought) and pathogen infection has been shown by taking examples from a few representative studies. (A) Impact of weather variables like temperature, rainfall and relative humidity (RH) on development of stem rot caused by Sclerotinia sclerotiorum in Cicer arietinum during the year 1993–1994 (Sharma et al., 2012). The figure shows increased incidence of stem rot under conditions of high humidity and high rainfall. (B) Effect of drought on Puccinia recondita infection in T. aestivum. Drought enhanced lesion development (Bethenod et al., 2001). (C) Effect of drought on Erysiphe cruciferarum infection in Alliaria petiolata. Drought and fungal infection had additive effect on plant growth. Drought although slowed disease development (decreased % diseased leaf area under drought conditions), plants under drought stress were much smaller as compared to well watered ones, so the powdery mildew occupied the total leaf area by the end of the experiment (Enright and Cipollini, 2007). (D) Effect of drought on infection by Rhizoctonia bataticola in Cicer arietinum. Drought (corresponding to 40% field capacity) predisposed chickpea to dry root rot (Sharma and Pande, 2013). All the graphs have been reconstructed from data taken from respective studies.
