“…The plant immune system and phytohormone signaling are interwoven [105]. While almost all major phytohormones have been linked to plant immunity at some level [106], jasmonic acid (JA), salicylic acid (SA) and ethylene (ET) are key regulators [105].…”

All land plants must cope with phytopathogens. Algae face pathogens, too, and it is reasonable to assume that some of the strategies for dealing with pathogens evolved prior to the origin of embryophytes – plant terrestrialization simply changed the nature of the plant-pathogen interactions. Here we highlight that many potential components of the angiosperm defense toolkit are i) found in streptophyte algae and non-flowering embryophytes and ii) might be used in non-flowering plant defense as inferred from published experimental data. Nonetheless, the common signaling networks governing these defense responses appear to have become more intricate during embryophyte evolution. This includes the evolution of the antagonistic signaling pathways of jasmonic and salicylic acid, multiple independent expansions of resistance genes, and the evolution of resistance gene-regulating microRNAs. Future comparative studies will illuminate which modules of the streptophyte defense signaling network constitute the core and which constitute lineage- and/or environment-specific (peripheral) signaling circuits.

“…Four basidiospores are 59 D r a f t D r a f t rp1 complex have been shown to confer a race non-specific resistance response to rust (Hulbert 81 1997). In contrast, race-specific resistance involves plant resistance genes that recognize the 82 pathogen avirulence gene effectors, triggering the plant defense response (Sekhwal et al 2015). 83…”

The aim of this work was to examine the function of phytohormones in the pathogenesis of cedar-apple rust, a fungal disease caused by Gymnosporangium juniper-virginianae Schwein. on Eastern red cedar (Juniperus virginiana L.) and crabapple trees (Malus spp. Mill.). Control cedar branchlets, gall tissues, fungal telial horns, as well as healthy and infected apple leaves were collected throughout fungal and plant development and used for profiling endogenous cytokinins (CK) and abscisic acid (ABA) by high performance liquid chromatography – electrospray ionization – tandem mass spectrometry. Phytohormone composition implicates cytokinin involvement in the development of rust infection. Moreover, increased levels of total CKs, as well as the unique profiles of sporulating galls on cedar trees, telial horns, and infected apple leaves, dominated by cis-Zeatin type CK, suggest that the fungus can synthesize hormones to facilitate the infection process. Distribution of ABA in the fungal and plant tissues indicates an important function of this stress hormone in regulating rapid changes in osmotic pressure during teliospore production by the galls. This study of the cedar-apple rust disease cycle is the first elucidation of phytohormones profiling between a pathogenic fungus and the attacked plant in a dual-host infection system.

“…These signalling pathways can interact during the defence response and can be dependent on each other to a certain degree. Both antagonistic and also synergistic interactions have been observed between SA-and JA-dependent defences (Robert-Seilaniantz et al 2011;Shigenaga & Argueso 2016). Treatment of cucumber roots with phenolic acids led to membrane damages accompanied by lipid peroxidation (Politycka 1997), which is a starting point of the JA biosynthetic pathway (Wasternack 2006).…”

“…Besides SA, other plant stress hormones such as abscisic acid (ABA) (Mauch-Mani & Mauch 2005;Cao et al 2011) and jasmonic acid (JA) (Pozo et al 2004;Halim et al 2006) may act in the defence signalling pathways in plant-pathogen interactions (Shigenaga & Argueso 2016). For example, exogenous application of JA effectively protected barley plants against infection by biotrophic powdery mildew fungus (Blumeria = Erysiphe graminis f.sp.…”

Plant Protect. Sci., 55: 31-42. Abstract:The effect of plant heat-shock (HS) pre-treatment (40.5°C, 2 h) on Pseudoidium neolycopersici development in the susceptible and moderately resistant Solanum spp. genotypes was studied together with biochemical responses (endogenous concentrations of salicylic (SA), jasmonic (JA), abscisic acid (ABA), and peroxidase (POX) activity). In HS pre-treated S. lycopersicum, an acceleration of pathogen, chlorosis and necrosis development, strong SA, JA accumulation, and increased POX activity were detected. In S. chmielewskii, HS pre-treatment caused a slight suppression of pathogen development, increase in JA, ABA concentrations, and POX activity. HS accelerated and strengthened the development of symptoms and biochemical responses to the infection in the susceptible genotype in contrast to moderately resistant genotype with a robust defence response to an infection per se.
