Influence of Inoculation of Leifsonia xyli subsp. xyli on Photosynthetic Parameters and Activities of Defense Enzymes in Sugarcane

Comparative analysis reveals changes in transcriptomes of sugarcane upon infection by Leifsoniaxyli subsp. xyli

“…It has been reported that brassinosteroids (BR) and abscisic acid (ABA) function in a broad range of disease resistances in tobacco and rice (Adie et al, ; Nakashita et al, ). In RSD‐infected sugarcane, the contents of gibberellin (GA), abscisic acid (ABA) and auxin (IAA) varied among different sugarcane varieties and tissues, suggesting the participation of these phytohormones in response to Lxx infection (Chen et al, ; Zhang et al, ). The current understanding of plant defence responses described above has been achieved through the study of a limited number of models, which may be constraining our view of the plant–pathogen interaction and the true capacity of plants to defend against pathogens.…”

The physiological characteristics and associated gene expression of sugar cane inoculated with Leifsonia xyli subsp. xyli

“…We used the Lxx strain GXBZ01 (accession number LFYU00000000) in this study, isolated and cultured from the sugar cane variety Badila. Bacteria were cultured in a modified M‐SC medium (Brumbley, Petrasovits, Birch, & Taylor, ), as described in our earlier publications (Zhang et al., , ).…”

“…The second of these, Badila, is highly susceptible to ratoon stunt and is also an important chewing cane variety in China. The other, GT11, is the main commercial sugar cane variety grown in Guangxi Province, China, and is susceptible to ratoon stunt; cane yield reductions as a result of this disease are seen in both plant and ratoon crops (Zhang et al., ). The cane setts used in this study comprised single buds from 10‐month‐old plants; both sugar cane varieties were subject to polymerase chain reaction (PCR) (Pan et al., ) to confirm the absence of Lxx , and setts were immersed in hot water at 50 ° C for 2 hr.…”

“…xyli ( Lxx ) (Davis, Gillaspie, Harris, & Lawson, ) and is an important disease globally because it is responsible for substantial crop yield losses (Comstock, ; Grisham, ; Li et al., ; Young et al., ). Infection affects not just the ratoon crop, but also impacts plant yields (Chen et al., ; Comstock, ; Steindl & Hughes, ; Zhang et al., , ).…”

“…Thus, interactions between the host plant and pathogen as well as their mutual recognition are key factors in the development of disease resistance (Lamb, Lawton, Dron, & Dixon, ). Previous work has shown that sugar cane growth, ultrastructure, endogenous hormones and photosynthetic characteristics are all adversely affected by ratoon stunt infection (Chen et al., ; Zhang et al., , ).…”
