“…Amongst biotic elements, fungal diseases are the most problematic. Macrophomina phaseolina the causative agent of charcoal rot is the pest that reduces yields up to 60% (Gaige et al, 2010). It is a highly virulent pathogen and causes diseases in many hosts including mungbean, okra, cucurbits, rice, maize and cotton (Shehzad et al, 1988).…”

Background: Mungbean [Vigna radiata (L.) Wilczek] is an important pulse crop globally. This imperative crop is severely affected by charcoal rot disease caused by Macrophomina phaseolina (Tassi) Goid. In the present study, the leaves of Calotropis procera L. were tested for their antifungal potential against M. phaseolina. Materials and Methods: Various concentrations i.e. 1%, 2.5%, 4%, 5.5% and 7% of methanolic extract of C. procera leaves were prepared and their in vitro bioactivity was examined against the test fungus. Methnolic leaf extract was partitioned using n-hexane, chloroform, ethyl acetate and n-butanol and antifungal activity of each fraction was evaluated. n-Hexane fraction was subjected to GC-MS analysis. Results: The higher concentration of methanolic leaf extract (7%) caused maximum inhibition in the diameter of M. phaseolina i.e. 38%. The n-hexane fraction of methanolic leaf extract was found to be the most effective against M. phaseolina. Seven compounds belonging to classes of chlorocarbon, aromatic hydrocarbon, azocompounds, aromatic carboxylic acids and fatty acids were identified in GC-MS analysis of n-hexane fraction. Conclusion: Antifungal activity of the methanolic leaf extract of C. procera might be due to the presence of the identified compounds in n-hexane fraction of methanolic leaf extract.

“…et al, 2013;Zheljazkov et al, 2013). The induction of secondary metabolite accumulation is a stress response, which depends on MeJA to coordinate the activation of the expression of multiple biosynthetic genes and the activity of diversifying enzymes (Gaige et al, 2010). MeJA-induced transcriptome changes have been analyzed in many different plant species including wheat and sweet basil (Diallo et al, 2014;Misra et al, 2014).…”

Abstract:Transcriptome profiling has been widely used to analyze transcriptomic variation in plants subjected to abiotic or biotic stresses. Although gene expression changes induced by methyl jasmonate (MeJA) have been profiled in several plant species, no information is available on the MeJA-triggered transcriptome response of Polygonum multiflorum Thunb., a species with highly valuable medicinal properties. In this study, we used transcriptome profiling to investigate transcriptome changes in roots of P. multiflorum seedlings subjected to a 0.25 mmol/L-MeJA rootirrigation treatment. A total of 18 677 differentially expressed genes (DEGs) were induced by MeJA treatment, of which 4535 were up-regulated and 14 142 were down-regulated compared with controls. These DEGs were associated with 125 metabolic pathways. In addition to various common primary and secondary metabolic pathways, several secondary metabolic pathways related to components with significant pharmacological effects were enriched by MeJA, including arachidonic acid metabolism, linoleic acid metabolism, and stilbenoid biosynthesis. The MeJA-induced transcriptome changes uncovered in this study provide a solid foundation for future study of functional genes controlling effective components in secondary metabolic pathways of P. multiflorum.

“…Charcoal rot of sorghum caused by M. phaseolina, soil and seed-borne disease of sorghum, is endemic to tropical and temperate regions of the world (Wyllie 1998). The disease severity may be enhanced by hot and dry environment (Gaige et al 2010) and may cause upto 100% yield losses (Bashir & Malik 1988). This disease can cause lodging and grain yield loss in the range of 23Á64% under favorable conditions (Mughogho & Pande 1984) besides adversely affecting the quality of fodder.…”

The fungal disease, charcoal root rot, caused by Macrophomina phaseolina is a foremost yield restraining factor of Sorghum bicolor L. around the world. The expression analysis of genes induced in general defense response can endow with clues to reveal major defense mechanisms against pathogen infection in sorghum plant. The role of chitinase and Stilbene synthase in response to M. phaseolina in sorghum was studied under control growth conditions using a real-time polymerase chain reaction. Here, we report the expression analysis of antifungal genes in two cultivars viz. PJ-1430 (resistant) and SU-1080 (susceptible) at different hours after inoculation with M. phaseolina isolate MTCC 2165. Chitinase and stilbene synthase were induced in PJ-1430 within 0 h, 24 h and in SU-1080 in 48 h, 24 h, respectively, after inoculation. However, the expression levels of chitinase and stilbene synthase in resistant cultivar were significantly higher. The results showed that chitinase and stilbene synthase can be effective to enhance resistance to M. phaseolina.
