Engineering broad root-knot resistance in transgenic plants by RNAi silencing of a conserved and essential root-knot nematode parasitism gene
TLDR
Bioengineering crops expressing dsRNA that silence target RKN parasitism genes to disrupt the parasitic process represents a viable and flexible means of developing novel durable RKN-resistant crops and could provide crops with unprecedented broad resistance to RKN.
Nematode pathogenesis and resistance in plants.
TLDR
Nematodes comprise a large phylum of animals that includes plant and animal parasites as well as many free-living species, and the Heteroderidae can be divided into two groups: the cyst nematodes, which include the genera Heterodera and Globodera; and the root-knot nematode, which is the most economic damage worldwide.
RFLP loci associated with soybean seed protein and oil content across populations and locations
TLDR
Two soybean populations were evaluated with restriction fragment length polymorphism (RFLP) markers to identify marker-quantitative trait locus (QTL) associations in different environments and populations, and interval mapping indicated that QTLs identified at Athens for seed protein and oil were different from those at Blackville.
Endogenous cellulases in animals: isolation of beta-1, 4-endoglucanase genes from two species of plant-parasitic cyst nematodes.
TLDR
The synthesis of EGases in the esophageal glands of the cyst nematodes Globodera rostochiensis and Heterodera glycines is reported on and it is revealed that the four catalytic domains belong to family 5 of the glycosyl hydrolases.
The parasitome of the phytonematode Heterodera glycines.
TLDR
The first comprehensive parasitome profile for a parasitic nematode is obtained and 51 new H. glycines gland-expressed candidate parasitism genes are identified, of which 38 genes constitute completely novel sequences.
A root-knot nematode secretory peptide functions as a ligand for a plant transcription factor.
TLDR
This discovery is the first demonstration of a direct interaction of a nematode-secreted parasitism peptide with a plant-regulatory protein, which may represent an early signaling event in the root-knot nematodes-host interaction.
Identification of quantitative trait loci for plant height, lodging, and maturity in a soybean population segregating for growth habit
TLDR
The use of molecular markers to identify quantitative trait loci (QTLs) has the potential to enhance the efficiency of trait selection in plant breeding and may be related to a few QTLs with large effects conditioning plant height, lodging, and maturity in this population.
