“…In contrast, peroxidase genes were not differentially expressed in the susceptible plants at either day 5 or 15 after aphid infestation. These data are consistent with a previously proposed hypothesis (Heng-Moss et al 2004;Franzen et al 2007;Gutsche et al 2009;Ramm et al 2013) that tolerant plants have the ability to elevate their level of reactive oxygen species (ROS)-scavenging enzymes, such as peroxidases, which enable them to efficiently remove intracellular ROS that accumulate in response to aphid feeding.…”

Prochaska, Travis J.; Donze-Reiner, Teresa; Marchi-Werle, L.; Palmer, N. A.; Hunt, Thomas E.; Sarath, Gautam; and Heng-Moss, Tiffany, "Transcriptional responses of tolerant and susceptible soybeans to soybean aphid (Aphis glycines Matsumura) herbivory" (2015). Abstract The soybean aphid, Aphis glycines Matsumura, was introduced in 2000 to North America and has become one of the most significant pests to soybean, Glycine max (L.) Merrill, production. Possible solutions to this problem are the use of resistant plants and the understanding of the genes involved in plant resistance. In this study, we sought to better understand the genes involved in the tolerance response of soybean plants to the soybean aphid, utilizing tolerant (KS4202) and susceptible (K-03-4686) plants. Studies were conducted under greenhouse conditions. Leaf samples of both tolerant and susceptible plants were collected at day 5 and day 15 after infestation and analyzed by sequencing-by-synthesis on an Illumina GA II X instrument. In the tolerant genotype, 3 and 36 genes were found to be differentially expressed in the infested plants compared to the control treatments at day 5 and day 15, respectively. A similar comparison in the susceptible genotype revealed 0 and 11 genes to be differentially expressed at day 5 and day 15, respectively. Predominately, genes related to plant defense, such as WRKY transcription factors, peroxidases, and cytochrome p450s, were upregulated in the tolerant genotype 15 days post-infestation by aphids. In contrast, none of these genes were similarly up-regulated in the susceptible plants, suggesting that consistent elevation of defense responses is important to plant tolerance. However, significant genotypic differences in global gene expression were also found when transcriptomes from control uninfested plants were compared at both day 5 and 15. qPCR validation of select genes confirmed our RNA-seq data. These comparisons indicate that potentially broader regulation of transcriptomes also contributes to the tolerance response and provides data that the tolerant genotype (KS4202) could be useful in soybean breeding programs trying to minimize production losses accruing from soybean aphid feeding.

“…In addition, the herbivore attempts to manipulate the plant's carbohydrate metabolism of the plant for its own use [47] As demonstrated in our study, [48] reported a decrease of the chlorophyll content of leaves infected by B. cinerea and infested with aphids, due to an increase in the production of defensive compounds. However, contrary to our findings, the work published by [49] on resistant cereals and studies on wheat by Franzel et al [50] reported that infestation of the plants with aphids had no significant effects on the rate of chlorophyll fluorescence. However, Rafi et al (1996) concluded that the response of plants to insect herbivore attack differ from species to species.…”

Bi-directional interaction between economically important fungal pathogen Botrytis cinerea and aphid Myzus persicea causes serious economic losses to the crop plants resulting in loss of both time and money spend. In bi-direction interaction the fungal pathogen and insect herbivores, can both interact directly with the plant and interact indirectly with each other as they struggle to compete for the resources of the plant. We investigated the bi-directional interaction between the necrotrophic and economically important fungal pathogen Botrytis cinerea Pers Fr (Helotiales Sclerotiniaceae) and the aphid Myzus persicae (Hemiptera Aphididae) on plant host, lettuce Lactuca sativa (Asteraceae: Compositae). Botrytis cinerea on host plant causes a brownish discoloration of the leaf petiole accompanied by the rotting of the leaves, however, presence of aphids on lettuce plants causes' economic damage directly through injury and indirectly through virus transmission, resulting in wilting and head contamination.In this study, it was found that negative interaction between B. cinerea and Myzus persicae was established. The presence of fungal pathogen B. cinerea and Myzus persicae stressed the host lettuce plant, resulting in significant reduction in the rate of photosynthesis and chlorophyll fluorescence, and reduction in the dry shoot and root weight of the lettuce plant. The study established that aphid population growth rate and the number of B. cinerea lesions decreased when both were present on the same host plant.

“…photosynthetic rates and fluorescence parameters) may help to explain the physiological mechanisms underlying plant resistance. Considerable progress has been made toward identifying the physiological responses of resistant and susceptible wheat to D. noxia (Burd and Elliott 1996;Franzen et al 2007;Haile et al 1999;Heng-Moss et al 2003;Macedo et al 2009), however; only limited information is available on the responses of resistant and susceptible barley to aphid feeding (Burd and Elliott 1996;Miller et al 1994). Research on the physiological responses of resistant and susceptible cereals has focused on several different areas including; chlorophyll and protein content, chlorophyll fluorescence, gas exchange, and molecular pathways.…”

“…Susceptible plants experience alterations in chlorophyll content (Ni et al 2002) such as chlorosis development, reductions in chlorophyll (a and b) and carotenoids, and changes in chlorophyll fluorescence (Burd and Elliott 1996;Franzen et al 2007;Heng-Moss et al 2003;Miller et al 1994;Rafi et al 1997). In contrast, resistant plants have been shown to exhibit minimal differences in chlorophyll maintenance in response to D. noxia feeding (Burd and Elliott 1996;Franzen et al 2007;Miller et al 1994).…”

“…The most recent studies on the physiological responses of resistant and susceptible cereal to D. noxia were conducted by Franzen et al (2007) and Macedo et al (2009).

Knowledge of the physiological responses of barley, Hordeum vulgare L., to the Russian wheat aphid, Diuraphis noxia (Mordvilko) (Hemiptera: Aphididae) is critical to understanding the defense response of barley to aphid injury and identifying resistance mechanisms. This study documented the impact of D. noxia feeding on resistant ('Sidney') and susceptible ('Otis') barley through chlorophyll fluorescence measurements, chlorophyll content, and carbon assimilation (A-C i ) curves recorded at 1, 3, 6, 10, and 13 days after aphid introduction. All chlorophyll fluorescence parameters evaluated were similar between aphid-infested and control plants for both cultivars. A-C i curves showed that D. noxia feeding negatively impacts the photosynthetic capacity in both cultivars, but this effect was greater in the susceptible plants. From the A-C i curves, it is apparent that compensation occurs in resistant barley by day 10, but by the conclusion of the experiment, aphid populations reached levels that overwhelmed the resistant barley seedlings. Differences observed in carbon assimilation curves between control and infested plants show that D. noxia feeding impacts the dark reaction, specifically rubisco activity and RuBP regeneration. It is likely that declines in the photochemical efficiency and chlorophyll content of the plants may be a secondary effect and not the primary trigger of declines in host plant function.
