Post-Infectional Biochemical Changes in <i>Cymbopogon martinii</i> (Roxb.) Wats and <i>Cymbopogon citratus</i> (DC) Stapf. Due to Leaf Rust Disease

Abstract

Post-infectional changes in sugars, ascorbic acid, protein, phenols, chlorophyll and carotene of two Cymbopogons viz., Cymbopogon martinii and Cymbopogon citratus due to leaf rust caused by Puccinia nakanishikii (Diet) were investigated. All the biochemical constituents decreased in plants infected by the fungal pathogen.

Leaf spot disease adversely affects human health-promoting constituents and withanolide biosynthesis inWithania somnifera(L.) Dunal

“…The degradation of metabolites due to pathogen infection or during fungal disease has also been reported in many crops (Chatterjee and Ghosh ; Tamuli et al . ).…”

“…It is believed that during fungal infection in the host plant, the pathogen secretes toxins and phytotoxic proteins which not only help in pathogen establishment but also adversely affect the biosynthesis of metabolites (Tsuge et al 2013). The degradation of metabolites due to pathogen infection or during fungal disease has also been reported in many crops (Chatterjee and Ghosh 2008;Tamuli et al 2013).…”
