“…Therefore, AMF can suppress or reduce plant pests and diseases through the induction of systemic resistance (Pozo and Azcon-Aguilar 2007;Pineda et al 2010;Jung et al 2012). Depending on the plant/pathogen/AMF interaction, MIR could be associated with systemic acquired resistance (SAR)-like priming of salicylic acid (SA)-dependent genes (Khaosaad et al 2007;Gallou et al 2011), but more often coincides with priming of jasmonic acid (JA)-dependent defenses, especially in grapevine (Li et al 2010;Hao et al 2012). In this case, MIR is thought to result from the active suppression of components in the SA-dependent defense pathway, causing systemic priming of JA-dependent defenses (Pozo and Azcon-Aguilar 2007).…”

Viticulture is a major worldwide economic sector with a vine area of 7.52 million ha, wine production of 288 Mhl, and wine exports of 26 billion euros. Nevertheless, viticulture has to adapt to new challenges of pest management, such as pesticide reduction, and climate change, such as increasing droughts. Viticulture adaptation can benefit from arbuscular mycorrhiza, a plant-fungus symbiosis. Here, we review the ecosystemic services of arbuscular mycorrhiza for grapevine production. The major points are the following: (1) arbuscular mycorrhiza fungi increase grapevine growth and nutrition by a better access to soil nutrients and by activating the regulation of plant transport proteins for phosphorus (P), nitrogen (N), and other elements. (2) Arbuscular mycorrhiza fungi increase the tolerance to abiotic stresses such as water stress, soil salinity, iron chlorosis, and heavy metal toxicity. (3) Arbuscular mycorrhiza fungi protect against biotic stresses such as root diseases. (4) Arbuscular mycorrhiza fungi produce glycoproteins and a dense hyphal network that increases soil stability and save soil nutrients up to 14 % of the grape production income. (5) P fertilisation reduces mycorhization. (6) Using herbaceous plants as cover crops favors arbuscular mycorrhiza fungi.

“…PR1 genes were first discovered in tobacco (Nicotiana tabacum L.) (Antoniw et al 1980), then many PR1 genes were identified from many monocotyledonous and dicotyledonous plants (Mitsuhara et al 2008;Li et al 2011). Most PR1 proteins with molecular weights of 14~17 kD are alkaline.…”

Pathogenesis-related (PR) proteins encoded by plant defense genes play key roles in plant disease-resistance responses, specialized in systemic-acquired resistance. However, their roles in the response of wheat to fungal infection are still not well known. Our earlier studies have reported that a full-length TcLr19PR1 gene (818 bp) was isolated from wheat infected by leaf rust (Puccinia triticina). Here, we showed that TcLr19PR1 was induced earlier and its expression level was higher in the incompatible interaction between seedling stage of wheat and P. triticina than in compatible interactions. TcLr19PR1 was strongly induced after P. triticina inoculation and ABA and SA treatments, in which the expression level of TcLr19PR1 significantly increased and reached the maximum at 12 and 72 h, respectively. Furthermore, the transgenic T 1 -stable TcLr19PR1 lines generated in the susceptible wheat cultivar Zhengzhou 5389 background exhibited certain extent disease resistance against P. triticina infection by preventing disease development. In addition, Western blotting was conducted to confirm that TcLr19PR1 protein was induced by P. triticina infection in positive transgenic plants at the protein expression level. These findings suggest that TcLr19PR1 gene plays an important role in wheat development and resistance to leaf rust pathogen attack.

“…Host-pathogen interactions involve complicated defences, generally, host plants express a wide range of resistance-related proteins in response to pathogen attacks, include pathogenesis-related (PR) enzymes [3]. A comprehensive understanding of the proteins induced by pathogens will help reveal the complex molecular mechanisms that mediate plant disease resistance and will aid the development of new strategies to increase disease resistance in some economically important crops.…”

“…More recently, the significance of resistance-related proteins has been reported for many plant-pathogen interactions [13, 14], and some intensive attempts have also been made to engineer resistance to apple disease. Several genes have been isolated that are related to apple disease resistance [3, 15–18]. The functions of some PR enzymes, including chitinases, β-1,3-glucanases and peroxidases, which act directly against pathogens, were also confirmed by some assays [15–17].…”

Understanding the defence mechanisms used by apple leaves against Alternaria alternate pathogen infection is important for breeding purposes. To investigate the ultrastructural differences between leaf tissues of susceptible and resistant seedlings, in vitro inoculation assays and transmission electron microscopy (TEM) analysis were conducted with two different inoculation assays. The results indicated that the resistant leaves may have certain antifungal activity against A. alternate that is lacking in susceptible leaves. To elucidate the two different host responses to A. alternate infection in apples, the proteomes of susceptible and resistant apple leaves that had or had not been infected with pathogen were characterised using two-dimensional electrophoresis (2-DE) and matrix-assisted laser desorption/ionisation time-of-flight tandem mass spectrometry (MALDI-TOF-TOF MS). MS identified 43 differentially expressed proteins in two different inoculation assays. The known proteins were categorised into 5 classes, among these proteins, some pathogenesis-related (PR) proteins, such as beta-1,3-glucanase, ascorbate peroxidase (APX), glutathione peroxidase (GPX) and mal d1, were identified in susceptible and resistant hosts and were associated with disease resistance of the apple host. In addition, the different levels of mal d1 in susceptible and resistant hosts may contribute to the outstanding anti-disease properties of resistant leaves against A. alternate. Taken together, the resistance mechanisms of the apple host against A. alternate may be a result of the PR proteins and other defence-related proteins. Given the complexity of the biology involved in the interaction between apple leaves and the A. alternate pathogen, further investigation will yield more valuable insights into the molecular mechanisms of suppression of the A. alternate pathogen. Overall, we outline several novel insights into the response of apple leaves to pathogen attacks. These findings increase our knowledge of pathogen resistance mechanisms, and the data will also promote further investigation into the regulation of the expression of these target proteins.
