“…After 48 hours of treatment, changes in biomass accumulation were observed. The similar pattern of biomass accumulation was recorded in foliar sprayed fennel (Hashmi et al 2012) or pepper plants (Elwan & El-Hamahmy 2009). Visible increase of biomass was also detected in chamomile plants continuously cultivated in medium enriched by 2 mM SA or with low concentration of SA (250 µM) (Kováčik et al 2009).…”

Salicylic acid regulates secondary metabolites content in leaves of Matricaria chamomilla

The influence of increasing doses of salicylic acid (SA) on selected physiological parameters and the content of coumarin-related compounds of diploid and tetraploid cultivars of Matricaria chamomilla plants were studied. Forty-eight hours after treatment SA showed growth-promoting effect with decrease in tissue water content, chlorophylls and soluble proteins. High doses of SA led to an increase of reactive oxygen species (hydrogen peroxide and superoxide radical) resulted in membrane damage (measured by accumulation of malondialdehyde). Changes in secondary metabolites accumulation in leaves were also observed. The pattern of quantitative changes of studied compounds was similar in tetraploid and diploid plants. The content of herniarin and its precursor (Z )-and (E )-2-β-D-glucopyranosyloxy-4-methoxycinnamic acid increased simultaneously. A considerable increase of umbelliferone and decrease in chlorogenic acid was registered. The rise of ene-yne-dicycloether in treated plant was also detected.

“…MeJA treatment increased expression of VTC1 and VTC2 transcripts and enhanced AsA accumulation in Arabidopsis (Sasaki-Sekimoto et al, 2005). SA application positively increased AsA content in pepper and strawberry leaves (Elwan and El-Hamahmy, 2009;Karlidag et al, 2009). The present study demonstrated that VpVTC was induced by SA, MeJA, and Eth in the resistant genotype 'Baihe-35-1', and the maximum induction occurred at 1, 0.5, and 6 h, respectively.…”

ABSTRACT. Using rapid amplification of cDNA ends, a full-length cDNA sequence of a GDP-L-galactose phosphorylase-like gene was isolated from leaves infected by Erysiphe necator in the Chinese wild (Vitis pseudoreticulata) clone, 'Baihe-35-1', an E. necator-resistant genotype. The full-length cDNA, designated as VpVTC, comprised 1943 bp and putatively encodes a 453-amino acid polypeptide containing an HIT motif. The deduced amino acid sequence showed high similarity with that of VTC genes from other plants. The expression of VpVTC, determined by reverse transcriptase-polymerase chain reaction, was induced by E. necator and defense signaling molecules, including salicylic acid, methyl jasmonate, and ethephon, in 'Baihe-35-1', the V. quinquangularis genotype 'Shang-24', and the E. necator-susceptible A GGP-like gene from a Chinese wild Vitis species V. pseudoreticulata genotype, 'Hunan-1'. Transcript levels of VpVTC correlated well with the degree of disease resistance in the 3 genotypes. Maximum induction of VpVTC by E. necator (>7-fold at 96 h postinoculation) occurred in 'Baihe-35-1', which also showed the fastest response to signaling molecules. Upregulating the expression of VpVTC in 'Baihe-35-1' resulted in a gradual increase in the ascorbic acid concentration of leaves inoculated with E. necator. Furthermore, VpVTC was expressed in leaves, stems, inflorescence, tendrils, and fruit at all developmental stages, with the highest level occurring in fruit 35 days after flowering.

“…However, the use of SA at high concentration (10 mM) caused tip-burn symptom on the shoot and young leaves (data not shown). In the similar vein, Babalar et al (2007) and Elwan and El-Hamahmy (2009) had explained that the use of SA at a high concentration may harm the produce. This work shows that preharvest SA application at 5 mM was a proper concentration controlling CI of lemon basil during cold storage.…”

“…In CI temperatures, elevated levels of reactive oxygen species (ROS), particularly H 2 O 2 , have been detected (Elwan and El-Hamahmy, 2009). Generally, there is a balance between the generation of ROS and ROS scavenging system in plant.…”

“…Recently, salicylic acid, a plant growth regulator and a safe chemical used to maintain postharvest quality, has been proven to be a major component inducing bioactive compounds such as antioxidants and antioxidant enzymes (Supapvanich and Promyou, 2013). Elwan and El-Hamahmy (2009) suggested that a range of antioxidant enzyme activities such as catalase (CAT), guaiacol peroxidase (G-POD) and asborbate peroxidase (A-POD) play important roles in removing H 2 O 2 which these enzyme activities are induced by SA. Hatamzadeh et al (2012) suggested that SA is able to eliminate ROS and lead to decreasing lipid peroxidation.…”
