“…These results correspond with previous results of some other authors (e.g. Niki et al 1998;Radwan et al 2008). Experiments with exogenously applied SA and JA demonstrated this antagonism in various plant species, suggesting an evolutionary conserved process (Spoel & Dong 2008).…”

Kyseláková H., Sedlářová M., Kubala M., Nožková V., Piterková J., Luhová L., Novák O., Ilík P. (2013): Reactive oxygen and nitrogen species and hormone signalling in systemic infection of pea by Pea enation mosaic virus. Plant Protect. Sci., 49: 105-119.The physiological responses of pea plants during 40 days of compatible interaction with Pea enation mosaic virus (PEMV) were evaluated. PEMV induces systemic changes in the concentration of phytohormones. At 5 days post inoculation (dpi), a simultaneous increase in abscisic acid (ABA) level and a decrease in salicylic acid (SA) level was observed, which is known to be involved in the suppression of hypersensitive reaction. In our pathosystem it preceded the virus presence in the systemic leaves. PEMV induces the accumulation of ABA, SA and Hsp70 and enhances peroxidase (POX) activity at 15 dpi, when it is already transmitted throughout the plant. The formation of enations was preceded by a local accumulation of nitric oxide, which was followed by the appearance of reactive oxygen species, mostly in the vicinity of leaf veins. Such heterogeneity suggests involvement of these molecules in the control of hyperplasia and tissue differentiation.

“…In addition, Kozlowski et al (2009) The amount of total chlorophyll in inoculated plants significantly decreased by two factors, mainly by loss in leaf photosynthetic area promoting less light absorption, and chloroplast disorders during pathogen infection (Radwan et al 2008). Furthermore, other secondary factors of the infection can occur where the pathogen causes the accumulation of reactive oxygen species (ROS) that cause inactivation/oxidation of pre-existing pigments in chloroplasts (Wu et al 1997;Alma´si et al 2000;Arias et al 2003).…”

“…The decrease in stomatal conductance of inoculated plants is a consequence of stomatal damage induced by the pathogen decreasing gas exchange (Radwan et al 2008). Disease progress causes stomatal conductance decrease.…”

The objective of this study was to: first, evaluate the infection effects caused by Colletotrichum lindemuthianum pathogen (race 2047) on photosynthetic pigments and gas exchanges in Phaseolus vulgaris plants (cv. Mexico 222); and, second, determine infection effects on leaf pigments and their consequences on photosynthesis rate. A completely randomized design with a factorial scheme was used, combining two treatments (control and inoculated) and three evaluation periods (4th, 8th and 12th day). Carotenoid levels presented decreases of 28.3% and 35% during the 8th and 12th day after infection, when control and inoculated plants were compared. Correlation analysis demonstrated the direct relationship between carotenoids and photosynthesis rate (r 00.84). Total chlorophyll in infected plants had progressive reductions of 6.4%, 20.6% and 21.3% on the 4th, 8th and 12th day, respectively, when treated and untreated plants were compared. Total chlorophyll with photosynthesis (r 00.85) also revealed a significant and linear correlation. The photosynthetic rate in infected plants decreased by 22%, 49.9% and 77.3% on the 4th, 8th and 12th days after the inoculation, respectively. Anthracnose infection also induced negative effects concerning stomatal conductance, transpiration, photosynthesis and water use efficiency. Our results demonstrate that leaf pigment reduction as a result of pathogens was the main cause of lower gaseous exchanges in infected plants.
