“…Moreover, it was previously documented that StWRKY1 participates in other defense pathways, including regulating phenylpropanoid metabolite gene expression, strengthening the secondary cell wall, and enhancing potato resistance to P. infestans [ 81 , 82 ]. Modifying the host cell wall to the plasma membrane continuum is critical for sensing and inducing several interlinked and independent defense signaling compounds, e.g., ROS/NO burst and cell death [ 83 ].…”

Nitric oxide (NO) is an essential redox-signaling molecule operating in many physiological and pathophysiological processes. However, evidence on putative NO engagement in plant immunity by affecting defense gene expressions, including histone modifications, is poorly recognized. Exploring the effect of biphasic NO generation regulated by S-nitrosoglutathione reductase (GNSOR) activity after avr Phytophthora infestans inoculation, we showed that the phase of NO decline at 6 h post-inoculation (hpi) was correlated with the rise of defense gene expressions enriched in the TrxG-mediated H3K4me3 active mark in their promoter regions. Here, we report that arginine methyltransferase PRMT5 catalyzing histone H4R3 symmetric dimethylation (H4R3sme2) is necessary to ensure potato resistance to avr P. infestans. Both the pathogen and S-nitrosoglutathione (GSNO) altered the methylation status of H4R3sme2 by transient reduction in the repressive mark in the promoter of defense genes, R3a and HSR203J (a resistance marker), thereby elevating their transcription. In turn, the PRMT5-selective inhibitor repressed R3a expression and attenuated the hypersensitive response to the pathogen. In conclusion, we postulate that lowering the NO level (at 6 hpi) might be decisive for facilitating the pathogen-induced upregulation of stress genes via histone lysine methylation and PRMT5 controlling potato immunity to late blight.

“…In their review, Des Marais et al (2013) [89] draw up a non-exhaustive list of genes underlying genotype-by-environment interaction in plant abiotic traits and bring to light a majority of transcription factors, photoreceptors and in less extent enzyme, binding protein and 2-component signaller. Likewise, transcription factors are largely involved in plant response to biotic stress [90,91]. Several recent studies stress out the transcription factor involvement in stress tolerance and their potential for crop improvement [92,93].…”

Renewed consumer demand motivates the nutritional and sensory quality improvement of fruits and vegetables. Specialized metabolites being largely involved in nutritional and sensory quality of carrot, a better knowledge of their phenotypic variability is required. A metabolomic approach was used to evaluate phenotypic plasticity level of carrot commercial varieties, over three years and a wide range of cropping environments spread over several geographical areas in France. Seven groups of metabolites have been quantified by HPLC or GC methods: sugars, carotenoids, terpenes, phenolic compounds, phenylpropanoids and polyacetylenes. A large variation in root metabolic profiles was observed, in relation with environment, variety and variety by environment interaction effects in decreasing order of importance. Our results show a clear diversity structuration based on metabolite content. Polyacetylenes, β-pinene and α-carotene were identified mostly as relatively stable varietal markers, exhibiting static stability. Nevertheless, environment effect was substantial for a large part of carrot metabolic profile and various levels of phenotypic plasticity were observed depending on metabolites and varieties. A strong difference of environmental sensitivity between varieties was observed for several compounds, particularly myristicin, 6MM and D-germacrene, known to be involved in responses to biotic and abiotic stress. This work provides useful information about plasticity in the perspective of carrot breeding and production. A balance between constitutive content and environmental sensitivity for key metabolites should be reached for quality improvement in carrot and other vegetables.

“…A similar observation was reported in the potato where expression of the StTCP23 was modulated during the infection of Streptomyces turgidiscabies (scad disease) and Fusarium solani. The susceptible and lethal symptoms of scad disease were signi cantly increased when StTCP23 was silenced in the potato [51]. It can be inferred from the present analysis in banana that after Foc infection in the root, plant tissues like leaf can sense the stress and triggered expression of the certain TCP (MaTCP4, MaTCP9 and MaTCP11).…”

The TCP transcription factor gene family is highly conserved among the plant species. It plays a major role in the regulation of flower symmetry, cell division, development of leaf, fibre and nodule in the plants by controlling the synthesis of various plant hormones. Banana is a major staple crop in the world. However, Fusarium oxysporum f. sp. cubense (Foc) infection is a major threat to banana production. The role of TCP gene family during the Foc infection is not explored till now. Herein, a total of 27 non-redundant TCP (MaTCP) gene sequences were retrieved from the banana genome and analysed for structural characteristics, phylogenetic correlation, subcellular, and chromosomal localizations. Phylogenetic analysis showed that the MaTCP proteins were highly conserved among different species and found to be the closest relative of the Oryza sativa and Zea mays. Promoter analysis of the TCP sequences showed that the cis-acting regulatory elements are associated with various stresses, environmental and hormonal signals. The higher transcripts accumulation in developing tissues (fruit finger, leaves, and stem) than of mature tissues (peel and pulp) showed a significant role of MaTCP in banana (cv. Rasthali) growth and development. Further, higher expression of the certain MaTCPs (MaTCP2, MaTCP4, MaTCP6, MaTCP9 and MaTCP11) in Foc race 1 infected root and leaf tissues of Rasthali indicated their promising role during Fusarium infection. This study will underpin the facet of TCP transcription factors on the development of biotic (Foc) stress tolerance in banana.
