TL;DR: Current progress made in the area of molecular crosstalk between host miRNAs and fungal invasion between plants and fungi is reviewed to understand the disease development.

TL;DR: In the current study, microbe-associated molecular pattern molecules, namely lipopolysaccharides, flagellin-22 and chitosan, and two chemical-based resistance inducers, acibenzolar-S-methyl and isonitrosoacetophenone, were used to trigger a primed state in Nicotiana tabacum cells.

TL;DR: Results suggest Scat1 is involved in modulation of ROS in a manner that deviates from the detoxification of H 2 O 2 , alters membrane integrity and contributes to the pathogenic success of S. sclerotiorum.

TL;DR: It is argued that the production of PD in avocado roots could be one of the mechanisms induced by AA that play an active role in the resistance against P. cinnamomi probably by regulating theProduction of H2O2.

TL;DR: Naturally occurring variation in resistance was found, with two lines being the most resistant and one line being themost susceptible to most of the insects and pathogens tested.

TL;DR: Findings suggested that overproduction of ROS involved in the pathogenicity of Fusarium in potato tubers may be linked to increased cell membrane integrity.

TL;DR: Phylogenetic analyses indicate that dinJ/relE and mqsR/ygiT are functional toxin-antitoxin systems and likely play different roles in regulation of X. fastidiosa population levels.

TL;DR: An updated picture of race status along with T3E profiles of north-west and -eastern Indian Xoo strains are brought and this insight would be of enormous importance in understanding rice–Xoo interaction through subsequent functional analysis of these T3Es in BB induction.

TL;DR: To understand the mechanistic model of symptom development and the role of programmed cell death (PCD) during infection, the levels of biochemical intermediates and stress responsive micro RNAs (miRNAs) with their target transcripts in Vigna unguiculata are compared.

TL;DR: Together, P. pachyrhizi seems to feign a necrotroph pathogen during early stages of infection to circumvent plant defense to biotrophs.

TL;DR: Results indicate that WRKY70 may play a critical role in suppressing virus multiplication, but not in elaborating HR cell death, by directly interacting with the CC-NB domains of RCY1.

TL;DR: The critical involvement of AsRGA29 in mediating multiple defense signaling pathways towards protecting garlic against FOC is suggested, which will help in developing RGA based markers linked to FBR resistance in garlic and onion.

TL;DR: It was found that membrane conductance, OD phenol, lignin and peroxidase activity play significant role in root resistance to P. capsici in 04-P24.

TL;DR: Results indicated that Bcphy3 encoding a histidine kinase is required for normal vegetative growth, sclerotia production, and pathogenicity in B. cinerea.

TL;DR: These findings imply that invasion of nematode triggers multiple signaling pathways both through tissue damage caused by nematodes invasion and recognition of nem atode elicitors by R genes.

TL;DR: Through the coordinated balance of generating, sensing and detoxification of ROS, A. alternata can colonize within the citrus hosts and is protected from deleterious effects of ROS.

TL;DR: The presented results support the role of salicylic acid, ascorbate, glutathione and protein S-thiolation in defense response of cucumber against P. syringae pv lachrymans.

TL;DR: Co-segregation analysis in most resistant and susceptible plants of F2 segregating population of Anugraha and Ujwala showed high level field resistance to this pathogen.

TL;DR: It is the first report of studying resistance mechanism in jute against M. phaseolina in a RIL population through transcript and miRNA analysis, suggesting silencing pathogenicity pathway of Macrophomina phaseolina.

TL;DR: Polyphenolic compounds found in cherry leaf extracts were identified and presented: fourteen hydroxycinnamates, fifteen flavonols, five flavan-3-ols and one flavon derivative.

TL;DR: The results suggest that seed priming with INA could enhance disease protection against X. perforans infection in tomato through the activation of defense genes.

TL;DR: A suppression subtractive hybridization library of resistant cultivar ‘Xingguang’ was constructed under phytoplasma stress to identify genes related to JWB resistance, and the expression of five selected genes was confirmed to upregulate at different infection periods.

TL;DR: Results suggest that the TaRH1 gene may participate in the plant stress response, a member of the DEAD-box family that encodes a putative ATP-dependent RNA helicase and is a members of the deadbox family.

TL;DR: Differences in the temporal regulation of the variables assessed during infection support the idea that the generation of reactive oxygen species (ROS) and subsequent regulation mediated by the action of antioxidant enzymes such as GPX are relevant to plant resistance to the vascular wilt causal agent.

TL;DR: Results suggested other oxilipins than jasmonate could be involved in signalling during interactions between the AM fungus and the pathogen in roots, suggesting a role of a basic endochitinase in these mycorrhiza-preformed barriers.

TL;DR: The key factors contributing to a greater tolerance to L. maculans were an effective antioxidant system and higher activity of PR proteins, i.e., chitinase and β-1,3-glucanase, and high utilization of soluble sugars during synthesis of the phenolic compounds in the pathogenesis was demonstrated in the resistant cultivar.

TL;DR: The results of this study demonstrate that apoplastic phenolics, in addition to often playing a role as antioxidants that reduce H2O2, can also cause rapid transient periods of extreme redox potential creating a local environment hostile to pathogen ingress.

TL;DR: Proteomics analysis of rice phylloplane secreted proteins shows that plant apoplastic proteins might play key roles in plant responses to biotic stress.

TL;DR: It is concluded that SpWRKY2 may play a role in the interaction between tomato and Phytophthora infestans.
