“…The concurrent increase of F 0 in these stressed plants also suggests the occurrence of a structural damage to PSII Reaction Centres (Krause, 1988;Bussotti et al, 2011a;Gottardini et al, 2014). Interestingly, the analysis of the MR parameters pointed out a difference in the drought response between Q. ilex and A. unedo, with the former showing a slower re-reduction of P700 þ and PC þ (decrease of v red ) resulting from a slower electron donation from P680, and the latter showing a concurrent reduced rate of photo-induced electron transfer through PSI (decrease of v ox ), indicating that a reduction of the PSI photochemical activity was also occurring (Oukarroum et al, 2012;Gao et al, 2014).…”

“…Exposure to O 3 can result in foliar lesions such as chlorosis and necrosis, but the appearance and the severity of these leaf injuries differ among plant species and varieties (Tamaoki 2008). However, it is well known that O 3 may produce functional alterations even without, before the onset of, or in addition to visible effects on a plant (Gottardini et al 2014). O 3 reacts with plants in a (1) solid (e.g., with the leaf cuticle), (2) gas (e.g., with hydrocarbons emitted by plants), and (3) liquid phase.…”

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.

“…Recent studies indicate that Chlorophyll fluorescence (ChlF) measurements may provide unique benchmarks to improve global agricultural productivity models, improving the reliability of crop yield projections under climate change scenarios (Guanter et al 2014;Malaspina et al 2014). More generally, ChlF is emerging as a very powerful tool in agricultural, environmental, and ecological studies (Gottardini et al 2014). One of its main advantages is that ChlF is a non-invasive tool, allowing scientists to get information on the photosynthetic process without destroying the tested sample.…”

Chlorophyll a fluorescence as a tool to monitor physiological status of plants under abiotic stress conditions

Plants living under natural conditions are exposed to many adverse factors that interfere with the photosynthetic process, leading to declines in growth, development, and yield. The recent development of Chlorophyll a fluorescence (ChlF) represents a potentially valuable new approach to study the photochemical efficiency of leaves. Specifically, the analysis of fluorescence signals provides detailed information on the status and function of Photosystem II (PSII) reaction centers, lightharvesting antenna complexes, and both the donor and acceptor sides of PSII. Here, we review the results of fast ChlF analyses of photosynthetic responses to environmental stresses, and discuss the potential scientific and practical applications of this innovative methodology. The recent availability of portable devices has significantly expanded the potential utilization of ChlF techniques, especially for the purposes of crop phenotyping and monitoring.
