“…Generally, jasmonates are vital in providing defense against biotic stresses, especially necrotrophic pathogens. Resistance against pests (such as herbivores, predatory, or parasitic arthropods) and pathogens can be enhanced by the jasmonate treatment that is an integral part of the plant defense signaling (Rohwer and Erwin 2008). In the case of an abiotic stress such as O 3 , Örvar et al (1997) reported that pretreating tobacco plants with jasmonates inhibited O 3 -induced cell death.…”

Plant Hormones Under Challenging Environmental Factors

Among various contaminants, ozone (O 3 ) is considered the most ubiquitous and phytotoxic atmospheric pollutant in industrialized and developing countries. It causes extensive risks for plant life, in terms of survival and productivity of wild and cultivated species. Plant response to O 3 resembles the biotic defense reactions and includes two steps: the first is a biphasic oxidative burst with a massive, rapid, and transient increase in apoplastic reactive oxygen species (ROS) production; the second is the induction of the hypersensitive response (HR) and systemic acquired resistance (SAR). In particular, the acute O 3 exposure (high concentrations for a few hours) results in the activation of programmed cell death (PCD) response that interacts with the synthesis of several hormones and other signaling molecules. The cross talk among all these molecules and their complex and interconnected signaling pathways are more important to determine (1) the initiation, propagation, and containment of O 3 -induced cell death, (2) the degree of the sensitivity of plants to this contaminant, and (3) the regulatory potential that plants have to promptly respond to oxidative stress. The present chapter reviews the role of phytohormones (such as ethylene, abscisic acid, gibberellins, auxins, and cytokinins) and other signaling molecules (such as salicylic and jasmonic acids, proline, and brassinosteroids), as well as their synergistic and antagonistic effects, in the complex signaling pathway involved in plant responses to O 3 stress.

“…The key oxylipin studied in this work ( figure 1 and table 1) was the stress hormone jasmonic acid, known to regulate plant growth and development as well as (biotic) defences against pathogens and pests (e.g. [65]). In addition, the latter studies also gave attention to actual evidence for altered biotic defences; it was found that the PsbS-deficient mutant (with lower levels of flexible NPQ and enhanced production of ROS and jasmonic acid) was more resistant to herbivore attack than the wild-type under field conditions (table 1).…”

This review focuses on feedback pathways that serve to match plant energy acquisition with plant energy utilization, and thereby aid in the optimization of chloroplast and whole-plant function in a given environment. First, the role of source-sink signalling in adjusting photosynthetic capacity (light harvesting, photochemistry and carbon fixation) to meet whole-plant carbohydrate demand is briefly reviewed. Contrasting overall outcomes, i.e. increased plant growth versus plant growth arrest, are described and related to respective contrasting environments that either do or do not present opportunities for plant growth. Next, new insights into chloroplast-generated oxidative signals, and their modulation by specific components of the chloroplast's photoprotective network, are reviewed with respect to their ability to block foliar phloem-loading complexes, and, thereby, affect both plant growth and plant biotic defences. Lastly, carbon export capacity is described as a newly identified tuning point that has been subjected to the evolution of differential responses in plant varieties (ecotypes) and species from different geographical origins with contrasting environmental challenges.

“…Exogenous application of JA stimulates leaf senescence and controls the expression of a series of senescence-related plant genes (van den Berg and Ewing, 1991). JAs can also alter physiological processes in plants, stimulate ageing, and induce faster plant propagation (Rohwer and Erwin, 2008). Martin-Closas et al (2000) showed that since JA might affect vegetative and root development in potato, in vitro effects of JA on the micropropagation of potato and its potential use in enhancing potato micropropagation are important.…”

“…Initially, JA was associated with senescence promotion (Koda et al 1991;Shan et al 2011) and microtuber formation (Koda and Kikuta, 2001), however, recent studies have shown that JA has unique and potentially useful properties that affect plant growth and development when applied exogenously van den Berg and Ewing, 1991;Rohwer and Erwin, 2008). JA is known in vitro microtuber promoting agent (van den Berg, 1991) that also affects vegetative growth and root development (Martin-Closas et al 2000).…”

Meristem derived in vitro plantlets of potato (Solanum tuberosum L.) cultivars Pasinler, Granola, and Caspar were micropropagated on agar-solidified MS medium containing different concentrations of jasmonic acid (JA) using single-node stem cuttings. The results of the study showed that inclusion of 1.0 µM JA in the MS medium provided a substantial and visible increase in most of the plantlet characteristics studied and the effect of this concentration was more pronounced compared to the control and all other JA concentrations. The highest number of shoots (8.00), nodes (19.00), leaves (19.00), and roots (15.75) on cv. Caspar and a maximum shoot length (15.13 cm) was observed on cv. Granola from 1.0 µM JA concentration. This concentration of JA also helped to induce longest roots (14.95 cm) on cv. Pasinler. The highest plantlet fresh weight from cv. Pasinler (649.38 mg), and cv. Caspar (630.18 mg), and maximum dry weight of plantlets from cv. Pasinler (98.58 mg), cv. Caspar (93.89 mg) and cv. Granola (79.03 mg) were noted on MS medium containing 1.0 µM of JA. Since the application of JA accelerates the multiplication of young plantlets throughout the year without depending on the season, this allows fast commercial propagation of new potato cultivars. These results may also serve as basis for the mass production of these economically important potato cultivars through in vitro micropropagation techniques and microtuberization studies.
