“…Thus, the first question was, “Are there discernible differences in local (i.e., bark) responses between two clones with varying susceptibility to CCD when they are artificially inoculated with Seiridum cardinale ?”. In SI bark, the S. cardinale ‐induced early production of JA (starting from 1 dpi until the end of the experiment) followed by the synthesis of Et, together with an accumulation of SA (from 3 dpi), in agreement with previously reported responses of plants challenged by pathogens (Kunkel & Brooks, 2002; Bari & Jones, 2009), as well as by abiotic stress (e.g., Pellegrini et al, 2016); while the reductions of SA at 6 and 13 dpi could be related to the consumption of this compound by cells in order to counteract the accumulation of reactive oxygen species (ROS; Kaya et al, 2023). According to Shigenaga and Argueso (2016), this outcome suggests that SA served as a mediator of cell survival (being part of the signalling pathways) by providing defence reactions (e.g., phenylpropanoid pathway) and regenerating active reduced forms, as confirmed by the significant increase of the total antioxidant capacity).…”

“…According to Shigenaga and Argueso (2016), the absence of any enhancement of JA and SA throughout the whole experiment (which even showed some decreases) confirms that these compounds were not involved in the regulation of signalling responses in the early phase of host‐pathogen interaction. In particular, the observed reduction of SA indicated that this antioxidant molecule could be consumed by the cell in order to counteract the possible ROS generation due to the increased cellular damage (as indicated by the increase of MDA by‐products at 1, 4, 9 and 13 dpi; Kaya et al, 2023), so SA could serve as a mediator of cell survival by providing better defence reactions rather than part of the regeneration of active reduced forms (as confirmed by the unchanged values of ORAC and HORAC observed throughout the whole experiment, except at 4 dpi; Saleem et al, 2021). These outcomes documented that the production of ABA and Et is required to activate local defence responses against S. cardinale infection/colonization in RI clones of C. sempervirens (García‐Andrade et al, 2000).…”

The necrotrophic fungus Seiridium cardinale is the main responsible for Cypress Canker Disease (CCD), a pandemic affecting many Cupressaceae worldwide. The present study aims to elucidate the signalling of the early responses in the bark and foliage of CCD‐susceptible and ‐resistant C. sempervirens clones to S. cardinale inoculation (SI and RI, respectively). In the bark of SI, a peaking production of ethylene (Et) and jasmonic acid (JA) occurred at 3 and 4 days post inoculation (dpi), respectively, suggesting an attempted plant response to the pathogen. A response that, however, was ineffective, as confirmed by the severe accumulation of malondialdehyde by‐products at 13 dpi (i.e., lipid peroxidation). Differently, Et emission peaked in RI bark at 3 and 13 dpi, whereas abscisic acid (ABA) accumulated at 1, 4 and 13 dpi, resulting in a lower MDA accumulation (and unchanged levels of antioxidant capacity). In the foliage of SI, Et was produced at 1 and 9 dpi, whereas JA and salicylic acid (SA) accumulated at 1 and 3 dpi. Conversely, an increase of ABA and SA occurred at 1 dpi in the RI foliage. This outcome indicates that some of the observed metabolic alterations, mainly occurring as local defence mechanisms, might be able to gradually shift to a systemic resistance, although an accumulation of MDA was observed in both SI and RI foliage (but with an increased antioxidant capacity reported only in the resistant clone). We believe that the results reported here will be useful for the selection of clones able to limit the spread and damage of CCD.

“…However, these positive effects, attributed to the role of the preharvest application of a particular elicitor at a given dose, cannot rule out the signalling crosstalk with other plant hormones or plant growth regulators that may be involved. Today, whether these elicitors modulate the high or low concentration of the plant hormones, their role during growth and ripening of yellow pitahaya are still unknown, although there is evidence in other fruit and vegetables [39]. SA is an essential signalling elicitor participating in plant responses to several type of stresses throughout a wide signalling crosstalk with ethylene, auxins, MeJa, abscisic acid, melatonin, or brassinosteroids [39][40][41].…”

Yellow pitahaya (Selenicereus megalanthus Haw.) is an exotic fruit with great potential for exportation in Ecuador. The research was carried out with the objective of evaluating the fruit growth and ripening as affected by four elicitors: salicylic acid (SA), methyl salicylate (MeSa), methyl jasmonate (MeJa), and oxalic acid (OA), all of them at 1, 5, and 10 mM concentration, compared with untreated plants (control). For each elicitor, nine plants were selected, and on each plant, three fruits were marked to follow up the growth by measuring polar and equatorial diameters. At harvest, yield (kg plant−1 and number of fruits plant−1), fruit weight, percentage of pulp and skin, total soluble solids (TSS), titratable acidity (TA), and firmness were determined. Treated plants enhanced fruit size, crop yield, and fruit weight compared with control fruits, although results depended on the elicitor tested and applied doses. The highest and lowest TSS were found in 10 mM MeSa and 5 mM MeJa-treated fruit, respectively, while the highest TA content was shown in 5 mM SA. Firmness was only enhanced in MeJa-treated fruits. Overall, results suggest that preharvest use of elicitors could modulate the pitahaya ripening and could improve quality attributes at harvest.

“…The quest for suitable techniques to induce salinity tolerance in plants continues, ultimately aiding them in combating the harmful effects of salt stress [21]. Salicylic acid (SA) is a phenolic compound that acts as a growth regulator in a wide range of physiological and biochemical processes, including plant growth, thermogenesis, flowering and ion uptake [22,23]. SA treatment also reduces lipid peroxidation, and it has the potential to interact with other plant hormones to make plants more resistant to the effects of salt stress [24].…”

Maize (Zea mays L.) is a salt-sensitive plant that experiences stunted growth and development during early seedling stages under salt stress. Salicylic acid (SA) is a major growth hormone that has been observed to induce resistance in plants against different abiotic stresses. Furthermore, plant growth-promoting rhizobacteria (PGPR) have shown considerable potential in conferring salinity tolerance to crops via facilitating growth promotion, yield improvement, and regulation of various physiological processes. In this regard, combined application of PGPR and SA can have wide applicability in supporting plant growth under salt stress. We investigated the impact of salinity on the growth and yield attributes of maize and explored the combined role of PGPR and SA in mitigating the effect of salt stress. Three different levels of salinity were developed (original, 4 and 8 dS m−1) in pots using NaCl. Maize seeds were inoculated with salt-tolerant Pseudomonas aeruginosa strain, whereas foliar application of SA was given at the three-leaf stage. We observed that salinity stress adversely affected maize growth, yield, and physiological attributes compared to the control. However, both individual and combined applications of PGPR and SA alleviated the negative effects of salinity and improved all the measured plant attributes. The response of PGPR + SA was significant in enhancing the shoot and root dry weights (41 and 56%), relative water contents (32%), chlorophyll a and b contents (25 and 27%), and grain yield (41%) of maize under higher salinity level (i.e., 8 dS m−1) as compared to untreated unstressed control. Moreover, significant alterations in ascorbate peroxidase (53%), catalase (47%), superoxide dismutase (21%), MDA contents (40%), Na+ (25%), and K+ (30%) concentration of leaves were pragmatic under combined application of PGPR and SA. We concluded that integration of PGPR and SA can efficiently induce salinity tolerance and improve plant growth under stressed conditions.
