“…Similarly, Janda et al (2014) reported that exogenous SA alleviates the damaging effect of various abiotic stresses and modulates the photosynthetic process of the plant. Few literatures have also established the role of exogenous SA in enhancing the resistance of wheat to biotic stresses (Underwood et al 2014).…”

High temperature reduces the growth and yield of most of the agriculturally important crops. Elicitors have been reported to modulate the thermotolerance of crops under abiotic stresses. Here, we studied the effect of salicylic acid (SA) on thermotolerance level of C306 (thermotolerant) and PBW343 (thermosusceptible) wheat cultivars grown under heat stress. Pilot experiment confirmed spraying of 100 mM SA prior to heat stress (38°C, 2 h) as the most effective treatment. Numerous protein spots were observed in C306 under SA ? HS compared to PBW343 during post-anthesis stage by 2-DE. Differentially expressed proteins were identified as signaling molecule, heat-responsive transcription factors (HSFs) and heat shock proteins (HSPs) using MALDI-TOF-TOF/MS analysis. Abundance of transcripts of HSFs, HSPs, CDPK, SOD, RCA, etc. was observed in C306 in response to SA ? HS, as compared to PBW343. C306 showed better accumulation of transcript of SAGs, osmolyte and total antioxidant capacity under SA treatment compared to PBW343. SA was observed to reduce the detrimental effect of HS on soluble starch synthase (SSS) activity as well as synthesis of starch granules in both the cultivars.

“…We have focused on studying the molecular basis of heat-induced loss of host plant resistance to insects using the wheat–HF interaction as a model [ 14 , 15 , 16 , 17 , 18 ]. The molecular and biochemical basis of wheat resistance and susceptibility to HF has been extensively investigated using genomics, functional genomics, and metabolomics technologies.…”

Heat stress compromises wheat (Triticum aestivium) resistance to Hessian fly (HF, Mayetiola destructor (Say)). This study aimed to investigate the impact of heat stress on transcript expression of wheat genes associated with resistance to HF infestation under normal and heat-stressed conditions. To this end, ‘Molly’, a wheat cultivar containing the resistance gene H13, was subjected to HF infestation, heat stress, and the combination of HF infestation and heat stress. Our RNA-Seq approach identified 21 wheat genes regulated by HF infestation under normal temperatures (18 °C) and 155 genes regulated by HF infestation when plants were exposed to 35 °C for 6 h. Three differentially expressed genes (DEGs) from the RNA-Seq analysis were selected to validate the gene function of these DEGs using the RT-qPCR approach, indicating that these DEGs may differentially contribute to the expression of wheat resistance during the early stage of wheat–HF interaction under various stresses. Moreover, the jasmonate ZIM domain (JAZ) gene was also significantly upregulated under these treatments. Our results suggest that the genes in heat-stressed wheat plants are more responsive to HF infestation than those in plants growing under normal temperature conditions, and these genes in HF-infested wheat plants are more responsive to heat stress than those in plants without infestation.

BackgroundBananas (Musa spp.) are the most important fruit crops worldwide due to their high nutrition value. Fusarium wilt of banana, caused by fungal pathogen Fusarium oxysporum f. sp. cubense tropical race 4 (Foc 4), is considered as the most destructive disease in the world and results in extensive damage leading to productivity loss. The widespread use of plant resistance inducers (PRIs), such as benzothiadiazole (BTH), is a novel strategy to stimulate defense responses in banana plants to protect against pathogens infection. The recent focus on the crop defense against fungal infections has led to a renewed interest on understanding the molecular mechanisms of specific PRIs-mediated resistance. This transcriptome study aimed to identify genes that are associated with BTH-induced resistance. Patterns of gene expression in the leaves and roots of BTH-sprayed banana plants were studied using RNA-Seq.ResultsIn this study, 18 RNA-Seq libraries from BTH-sprayed and untreated leaves and roots of the Cavendish plants, the most widely grown banana cultivar, were used for studying the transcriptional basis of BTH-related resistance. Comparative analyses have revealed that 6689 and 3624 differentially expressed genes were identified in leaves and roots, respectively, as compared to the control. Approximately 80% of these genes were differentially expressed in a tissue-specific manner. Further analysis showed that signaling perception and transduction, transcription factors, disease resistant proteins, plant hormones and cell wall organization-related genes were stimulated by BTH treatment, especially in roots. Interestingly, the ethylene and auxin biosynthesis and response genes were found to be up-regulated in leaves and roots, respectively, suggesting a choice among BTH-responsive phytohormone regulation.ConclusionsOur data suggests a role for BTH in enhancing banana plant defense responses to Foc 4 infection, and demonstrates that BTH selectively affect biological processes associated with plant defenses. The genes identified in the study could be further studied and exploited to develop Foc 4-resistant banana varieties.Electronic supplementary materialThe online version of this article (10.1186/s12864-018-4830-7) contains supplementary material, which is available to authorized users.
