Gene Ontology analyses of RNA seq data obtained from MAPK3-1-overexpressing (OE) and MAPK3-2-OE roots compared to their control, as well as MAPK3-1-RNA interference (RNAi) and MAPK3-2-RNAi compared to their control, hierarchically orders the induced and suppressed genes, strengthening the hypothesis that their heterologous expression in Gossypium hirsutum (upland cotton) would impair parasitism by the root knot nematode (RKN) Meloidogyne incognita. (bvsalud.org)
Consistently, significant down-regulation in transcript levels of the Hg-rps23, Hg-snb1, Hg-cpn1 genes were observed in the nematodes feeding on the transgenic roots, suggesting a broad-spectrum resistance mediated by the host-mediated silencing of vital H. glycines genes. (bvsalud.org)
Infection2
In the present study, we produced stable transgenic soybean plants individually harboring the inverted repeats of three essential H. glycines genes, Hg-rps23, Hg-snb1, and Hg-cpn1, and evaluated their resistance to SCN infection. (bvsalud.org)
There were no significant differences in morphological traits between transgenic and NT soybean plants under conditions with negligible SCN infection. (bvsalud.org)
Performance2
G. L. Tylka, " Get the Latest Information on Performance of SCN-resistant Soybeans ", 2013. (iastate.edu)
In summary, our results demonstrate the effectiveness of host-induced silencing of essential H. glycines genes to enhance broad-spectrum SCN resistance in stable transgenic soybean plants, without negative consequences on the agronomic performance. (bvsalud.org)
Aphis1
The soybean aphid (Aphis glycines Matsumura) is one of the most important insect pests of soybeans in the North-central region of the US. (bvsalud.org)
Brown stem rot1
Soybean plants challenged with the brown stem rot fungus or with soybean cyst nematodes did not present changes in fatty acid levels in leaves or seeds, indicating that the changes induced by aphids are not a general response to pests. (bvsalud.org)
Yield2
A meta-analytic approach was used to summarize data on the effects of fluopyram-amended seed treatment on sudden death syndrome (SDS) and yield of soybean (Glycine max L.) in over 200 field trials conducted in 12 U.S. states and Ontario, Canada from 2013 to 2015. (bvsalud.org)
The variation in yield response was explained partially by disease severity (19%), geographic region (8%), and sowing date (10%) but not by the resistance level of the cultivar. (bvsalud.org)
Avoid2
It has been hypothesized that aphids avoid effective defenses by inhibition of jasmonate-regulated plant responses. (bvsalud.org)
thus, these changes in fatty acid metabolism may be examples of "metabolic hijacking" by the aphid to avoid the induction of effective defenses. (bvsalud.org)
Management1
Sustainable use of insect resistance in crops require insect resistance management plans that may include a refuge to limit the spread of virulence to this resistance. (bvsalud.org)
