Bactrocera dorsalis; Insecticide resistance; Mass spectrometry; Trichlorphon; Two-dimensional gel electrophoresis

Functional proteins in larvae of Bactrocera dorsalis, a major fruit pest, play a central role in their resistance to organophosphorus insecticides. Changes in proteins in B. dorsalis larvae after trichlorphon treatment may have a role in the resistance response to trichlorphon. We analyzed 14 protein spots of crude proteins from B. dorsalis larvae post-treatment ... more

Cowpea (Vigna unguiculata) is of great importance for human consumption due to its high nutritional value. The crop is grown in tropical and subtropical regions of the world; however, grain productivity is severely affected by water restriction imposed by long periods of drought in semiarid regions. We compared two contrasting cowpea genotypes for drought ... more

Antagonistic bacteria; Bacillus pumilus; Identification; Marine microorganisms; Rice blast fungus

In this paper, a plate confrontation method was used to isolate bacteria antagonistic to the rice blast fungus Magnaporthe grisea from samples collected from China’s Dalian Bay. The antagonist strain LM-031 was obtained. We studied this strain’s morphological, physiological and biochemical characteristics and analyzed its 16S rDNA sequence. We compared the effects of different ... more

Apis cerana; Differential expression; Proteome; Varroa destructor

The mite (Varroa destructor) has become the greatest threat to apiculture worldwide. As the original host of the mite, Apis cerana can effectively resist the mite. An increased understanding of the resistance mechanisms of Eastern honeybees against V. destructor may help researchers to protect other species against these parasites. In this study, the proteomes ... more

Ecology; Flue-cured tobacco; Leaf quality; Proteome; Two-dimensional electrophoresis

The leaves of tobacco plants were used to analyze differences in protein content of tobacco grown in the four main flue-cured tobacco-producing areas of Sichuan Province, China. An improved protein extraction method, isoelectric focusing/sodium dodecyl sulfate-polyacrylamide gel electrophoresis two-dimensional gel electrophoretic separation, was used to extract and separate total protein from ... more

Fusarium wilt caused by Fusarium oxysporum f. sp lycopersici (Fol) is one of the main diseases affecting tomatoes. The BHRS 2,3 genotype of tomato is, however, resistant to this disease. A proteomic approach was used to understand the defense mechanisms of this genotype using the tomato root, the first tissue that interacts with the fungus, as a target. Protein was extracted and separated by ... more

Plant Proteins; Proteome; Sapindaceae; seeds

Paullinia cupana Kunth var. sorbilis (Mart.) Ducke, the cultivated guarana plant, is native to the Amazon and has been valued for its medicinal, stimulant and energetic properties for centuries. The seeds are the main commercial product of the plant and the source of high amounts of purine alkaloids (caffeine and theobromine) and polyphenols (flavonoids, catechins, and tannins). Proteins ... more

Interaction; Nitrogen resource; Rice; Rice blast fungus; Small secreted proteins

Previous studies have shown that the blast fungus, Magnaporthe oryzae, may experience nitrogen starvation during infection of its plant host (rice,Oryza sativa). Here, we studied the expression of seven genes encoding cysteine-rich proteins with N-terminal signal peptides during nitrogen limitation and throughout the infection process. Some genes were upregulated to a greater ... more
