“…Citric acid was upregulated in the tolerant inoculated cultivars, but it was below the level of detection in the susceptible inoculated cultivars, proving its role in the defense of potato roots against Sss. Similarly, the role of citric acid in improving plant vigor against pathogen attack was also demonstrated in Zea mays [32]. Azelaic acid was also significantly upregulated in the tolerant cultivars in the current study.…”

Plants defend themselves from pathogens by producing bioactive defense chemicals. The biochemical mechanisms relating to quantitative resistance of potato to root infection by Spongospora subterranea f. sp. subterranea (Sss) are, however, not understood, and are not efficiently utilized in potato breeding programs. Untargeted metabolomics using ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) was used to elucidate the biochemical mechanisms of susceptibility to Sss root infection. Potato roots and root exudate metabolic profiles of five tolerant cultivars were compared with those of five susceptible cultivars, following Sss inoculation, to identify tolerance-related metabolites. Comparison of the relative metabolite abundance of tolerant versus susceptible cultivars revealed contrasting responses to Sss infection. Metabolites belonging to amino acids, organic acids, fatty acids, phenolics, and sugars, as well as well-known cell wall thickening compounds were putatively identified and were especially abundant in the tolerant cultivars relative to the susceptible cultivars. Metabolites known to activate plant secondary defense metabolism were significantly increased in the tolerant cultivars compared to susceptible cultivars following Sss inoculation. Root-exuded compounds belonging to the chemical class of phenolics were also found in abundance in the tolerant cultivars compared to susceptible cultivars. This study illustrated that Sss infection of potato roots leads to differential expression of metabolites in tolerant and susceptible potato cultivars.

“…Also, Ström et al (2005) report that the nutrient extraction efficiency increases through the application of citric acid (10 mM). Martinez-Pacheco et al (2011) reported that citric acid differentially induced proteolytic activity and vigor in the corn hybrids. Sadak et al (2013) reported that coapplication of ascorbic acid and citric acid may alleviate the harmful effects of salinity stress.…”

This research was conducted during 2016-2017 awheat growing season to investigate the effects of different rates of seed coating of an organic acid mixture (citric acid, glutamate, and proline) on yield and quality of wheat. The field experiments were established in Dogankent and Haciali locations of Eastern Mediterranean Agricultural Research Institute in Turkey. Study was carried out with randomised complete block design with 4 replications and Ceyhan-99 bread wheat variety was used as seed material. Before seeding, wheat seeds were coated with organic acid mixture product (0.75% citric acid, 0.25% glutamate, 0.25% proline, 2% Zn and 96.75 water), in three different doses (500 ml ton-1, 1 l ton-1, 1.5 l ton-1) to compare with control (uncoated). There were statistically significant differences at 5% level in 1000 grain weight and grain yield values in Dogankent location and 1000 grain weight, grain yield and number of spikes in Hacialilocation. Highest yield values were obtained from 500 ml t-1 application dose for both locations. With 500 ml t-1 application dose at Dogankent location, grain yield was 11.9 t ha-1 which was 8.97% higher over control. In Hacali location, 500 ml t-1 application dose was increased yield by 15.96% compared to control which resulted with 10.5 t ha-1 grain yield. No statistically significant difference was observed in quality characteristics (protein, gluten, hardiness and sedimentation) in trials.
